It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
The data transmission method of the heterogeneous system can be applied to an application environment shown in fig. 1. Wherein the user terminal 102 communicates with the server 104 via a network. The client 106 communicates with the server 104 over a network. The server 104 may receive instructions sent by a plurality of different terminals or clients at the same time, and perform related operations or forward the instructions according to the received instructions. The server 104 receives a service request pushed by the data center, where the service request is a service request initiated by the user terminal 102. The server 104 issues an instruction to the corresponding client 106 with the established long connection according to the service request, and the client 106 is used for interfacing interaction data between the intranet and the extranet.

The terminal 102 may be, but not limited to, various personal computers, notebook computers, smartphones, tablet computers, and portable wearable devices, and the server 104 may be implemented by a stand-alone server or a server cluster composed of a plurality of servers.
In one embodiment, as shown in fig. 2, a data transmission method of a heterogeneous system is provided, and the method is applied to the system in fig. 1 for illustration, and includes the following steps:
step 202, the server receives a service request pushed by the data center, where the service request is a service request initiated by the user terminal.
By adopting a unified business management information platform, all resources and information on the enterprise interior and the enterprise exterior supply chain can be managed uniformly, the integration can eliminate various information barriers and information islands caused by division in the enterprise, for example, the effective management of the whole supply chain can be realized by utilizing an enterprise resource planning system, ERP (Enterprise Resource Planning) enterprise resource planning is an enterprise information management system which is mainly used for integrated management of material resources, fund resources and information resources in the manufacturing industry. The business systems used inside each enterprise may have a plurality of business systems such as OA office systems, business processing systems, etc., and the business systems used between different enterprises may be very different (heterogeneous systems). Meanwhile, enterprise business systems are generally deployed in enterprise intranets, and related business databases are generally not accessible through public networks based on security considerations. Specifically, a user can log in a service system of a specific scene by inputting a user name and a password in a PC end or a mobile phone Application program or a browser webpage, the user can initiate a specific service request through an app (Application program) or a web browser, a background of the service system receives the service request sent by a user terminal and pushes the service request to a server through a data center, the server can receive the service request pushed by the data center, and the service request comprises services of different enterprise systems. The user terminal refers to a program corresponding to the server and providing local service for the user. Except for some applications that only run locally, they are typically installed on a common client and need to run in conjunction with the server. The service request refers to a service request corresponding to a service function initiated by a user in different service scene systems according to different requirements, and different enterprises at the upstream and downstream of a supply chain can be involved in the processing process of the service request to process different data, so that data interaction is required to be performed across the enterprise systems to obtain a final service processing result. Business systems under corresponding scenes can be created by enterprises according to different business requirements, for example, an internet of vehicles business system, an internet of things system and the like, business data among the business systems of different enterprises are completely isolated, and the business data can comprise business service data, worksheet data, organization data and the like. For the same enterprise, a plurality of business systems in different scenes can be built in the enterprise, and a user management center of the business system uses a unified set of organization, role information and user information, namely, data of the organization, the role, the user and the like which are uniformly arranged can be shared by all departments in the same enterprise. Different departments of the enterprise can create own business services of the departments through logging in the management account numbers on an application management center interface. Different enterprises or departments may create business application services that belong to different roles under their own organizational framework. For example, in online shopping applications, a user needs to create an order, and during the processing of this business request, the data in the "Customer service system and the data in the" Product service system need to be read. The server needs to send instructions to the client service system and the product service system to search corresponding data according to the order creation request sent by the user side. The user can initiate an order creation request through triggering operation, and the order creation request is sent to the server through a data center in the system, wherein the service request comprises a user terminal identifier, and the user terminal identifier is used for identifying a unique user terminal.
In step 204, the server issues an instruction to the corresponding client with the established long connection according to the service request, where the client is used for interfacing interaction data between the intranet and the extranet.
After the server receives the service request pushed by the data center, the server can issue an instruction to a corresponding client with established long connection according to the service request, wherein the long connection client is used for interfacing interaction data between the enterprise intranet and the extranet. The long connection client automatically connects to the long connection service cluster according to the login account when starting, and maintains a long connection state with the server. For example, in an online shopping system, a user may initiate a create order request by triggering an operation and send it to a server through a service gateway or data center. When the server receives the order creation request sent by the user terminal pushed by the data center, the server can send an instruction to a corresponding client with established long connection according to the order creation request, and the long connection client is used for interfacing interaction data between the enterprise intranet and the extranet, so that the following functions can be realized: connecting with an enterprise business database; receiving a working instruction from a server, and processing the instruction to finish the functions of fetching and writing data from an enterprise business database; detecting the network state in real time, and automatically recovering the connection with the server after the network is disconnected; the enterprise user may choose to turn on or off certain functions as desired.
And 206, the client processes the data related to the service request according to the service processing logic in the instruction to obtain a service processing result related to the service request, and returns the service processing result to the data center, and the data center processes and analyzes the service processing result to obtain a result corresponding to the service request and returns the result to the user terminal.
After the server issues an instruction to the corresponding client with the established long connection according to the service request, the client processes data related to the service request according to the service processing logic in the instruction to obtain a service processing result related to the service request, and returns the service processing result to the data center, and the data center processes and analyzes the service processing result to obtain a result corresponding to the service request and returns the result to the user terminal. When the client processes the service request, the client may need to obtain the data of the database in the enterprise intranet corresponding to the client at the same time. For example, when the client receives the service request forwarded by the server, the client accesses the service database in the intranet through the private address to process the service request, after obtaining the service processing result corresponding to the service request, the client can keep a long connection state with the server through the public network address to realize the isolation of the intranet and the extranet, and returns the service processing result to the server, and then returns the service processing result to the data center, and after the data center further processes and analyzes the service processing result, the result corresponding to the service request is obtained and returned to the user terminal. The server in the application expands and deploys new functions beyond the original service functions, and the server cluster can achieve the capability of supporting more user accesses simultaneously by adding the server and deploying linear resource expansion of related services.
In this embodiment, when data transmission needs to be performed across service systems, the server receives a service request pushed by the data center, where the service request is a service request initiated by the user terminal. Compared with the traditional data transmission mode, the server can send an instruction to the corresponding client with the established long connection according to the service request, and the client is used for interfacing the interactive data between the enterprise intranet and the enterprise extranet. The client processes the data related to the service request according to the service processing logic in the instruction to obtain a service processing result related to the service request, and returns the service processing result to the data center, and the data center processes and analyzes the service processing result to obtain a result corresponding to the service request and returns the result to the user terminal. Therefore, based on the long connection frame, data exchange transmission under a cross-enterprise, namely cross-business system scene can be realized, the problems of cross-enterprise heterogeneous system data fusion and data synchronization are solved, meanwhile, the security problems such as network service attack and the like possibly caused by the fact that a client carries an access address of a long connection cluster are avoided, and the heterogeneous system data transmission can be effectively carried out while the system security is ensured.
In one embodiment, the service request includes services of different enterprise systems, and after returning the service processing result to the data center, the method further includes a step of issuing an instruction to a downstream client corresponding to the service processing result, and specifically includes:
and the data center issues a command to a downstream client corresponding to the service processing result according to the service processing result.
And the downstream client processes the data related to the service request according to the instruction to obtain a service processing result related to the service request, and returns the service processing result to the data center.
When the client processes the data related to the service request according to the service processing logic in the instruction, a service processing result related to the service request is obtained, and the service processing result is returned to the data center, and the service request contains the services of different enterprise systems in the supply chain, so that the server can further continue to issue the instruction to the downstream client corresponding to the service processing result. Specifically, a service integration architecture diagram of the heterogeneous system as shown in fig. 3. The data center in the heterogeneous system, i.e. the integrated system, of the cross-enterprise can issue instructions to the downstream client corresponding to the service processing result according to the service processing result of the client corresponding to the upstream enterprise, so that the downstream client processes the data related to the service request according to the instructions to obtain the service processing result related to the service request, and returns the service processing result to the data center. And the data center processes and analyzes the results obtained after the cooperative processing of the upstream enterprise client and the downstream enterprise client in the service supply chain, obtains the results corresponding to the service request and returns the results to the user terminal. Therefore, the security of each upstream and downstream enterprise system can be ensured, and the upstream and downstream enterprise clients of the supply chain related to the service request can cooperatively process the service request, so that the data transmission among different subsystems can be effectively carried out.
In one embodiment, the client is connected to a service database in the intranet, and the step of processing data related to the service request by the client according to the service processing logic in the instruction includes:
and the client acquires related data from a service database in the enterprise intranet according to the service processing logic in the instruction and processes the data related to the service request.
After the server receives the service request pushed by the data center, the server can issue an instruction to the corresponding client with the established long connection according to the service request, and issue an instruction to the client involved in the service request processing process, where the instruction is used to instruct the client to acquire related data from a service database in the enterprise intranet according to the service processing logic in the instruction, so as to process the data related to the service request. The client is connected with a service database in the enterprise intranet, the client can be installed on an independent server, the server can access the service database through a private address, and the client is connected with the server through a public network address to realize the isolation of the enterprise intranet and the enterprise intranet. In the application, the client is a data service center for opening the intranet and the extranet, for example, an independent machine can be allocated in the intranet for deployment, and the network access of the machine can be independently configured with a security policy, so that the intranet data service is opened to the minimum degree, and the security of the system in data transmission is effectively ensured. Specifically, when the client is started, the client can automatically connect to the long connection service cluster in a login account mode to keep connection with the server. The server can issue instructions to corresponding clients with established long connections according to the received service requests, the clients are connected with a service database in the enterprise intranet, and the instructions issued by the server are used for instructing the clients to acquire relevant data from the enterprise intranet and process the instructions. The long connection client side can comprise a short connection login service and a long connection login service, after the user successfully logs in through the short connection through an account number and a password, the long connection cluster connection parameters can be obtained, and the client side accesses the long connection service cluster according to the obtained long connection parameters. For example, when the server cluster receives a connection request sent by the client a, the server returns corresponding connection parameters to the client according to the connection request, and establishes long connection with the client according to the connection parameters, where the client allocates service nodes automatically, for example, the service node CPU or IO capability may be allocated automatically according to the number of connections of the service node client. The long connection server cluster is characterized in that a cluster architecture is adopted for long connection service, so that single service node access to single machine limitation of a client can be prevented, service stop caused by single node service interruption can also be prevented, and high availability and real-time capacity expansion capability of the system are realized. The server can realize the following functions: managing access of a long connection client; forwarding or issuing instructions to the corresponding long connection clients; the service nodes are communicated with each other, and corresponding clients are automatically transferred to other service nodes for management when the service nodes exit abnormally; and processing a client request instruction (such as data uploading), and pushing corresponding service data to a data center after the related instruction is executed. The data center refers to a processing center for enterprise data calculation, storage, analysis and the like, and can provide data service for an application terminal. Therefore, the login safety is ensured by long connection of the login instruction, the problem of cross-enterprise business data integration is solved by constructing a high concurrency distributed instruction exchange architecture, and heterogeneous system data transmission can be effectively performed while system safety is ensured.
In one embodiment, the heterogeneous system further comprises a data service function end, wherein the data service function end is used for issuing a priority authority instruction through a preset function account. When the service is started, the data service function end accesses the server according to the preset starting parameters, the server can be a long connection server cluster, when the data service function end receives a service data acquisition request sent by the user terminal, the data corresponding to the service data request is acquired from the data center in a short connection request mode according to the service data acquisition request, and the data is returned to the user terminal. The client comprises a data service function end, namely a long connection function end, wherein the long connection function end is a special long connection client, and a special account is allocated to execute a high-authority management instruction, such as controlling and designating a common client. The long connection function end is used for issuing a priority authority instruction through a preset function account number, a short connection user password login process is not needed to obtain long connection information, when the service is started, the long connection function end is accessed into the long connection server cluster according to a preset starting parameter, the long connection function end can issue an instruction to the server cluster, the instruction carries an instruction identification, and the instruction identification is used for indicating the server cluster to control the client according to the instruction identification. When the data service function receives a service data acquisition request sent by the user terminal, acquiring data corresponding to the service data request from the data center in a short connection request mode according to the service data acquisition request, and returning the data to the user terminal. In addition, when the data service function receives a service request sent by the user terminal, the service request is pushed to the server in a long connection request mode according to the service request, and a command is issued to the corresponding long connection client to execute related operations through the server according to the service request. Therefore, different ends can be allocated for processing according to different functions of the instruction set and the division of different function roles, for example, the instruction set of the client side mainly comprises management instructions such as data uploading and the like, and requests of the server side to allocate storage space instructions and the like are initiated; the long connection function end is responsible for specific allocation storage space request processing, issuing instructions to the server cluster and the like, has different instruction processing capacity from that of the common connection client, has a special processing instruction set, distributes corresponding functions in a service form after packaging the long connection function end, and provides the function end designated functions for other integrated systems or data centers for use in a public service interface form, thereby effectively solving the problem of data transmission of an enterprise business system across enterprise intranets deployed in an intranet, and realizing configuration of server system resources on demand through a high-concurrency expandable cluster.
In one embodiment, after returning the service processing result to the data center, the method further includes a step of calling the corresponding service instance according to the third party integrated system identifier, and specifically includes:
and receiving a service call request sent by the third-party integrated system through the long-connection service proxy end, wherein the service call request carries a third-party integrated system identifier, and the long-connection service proxy end is used for distributing corresponding functions in a service form after packaging the long-connection function end and providing specified functions for an external integrated system through a service interface form.
And after the identity authentication of the third-party integrated system identifier is successful, calling a corresponding service instance according to the third-party integrated system identifier.
After the server returns the service processing result to the data center, the long connection server cluster can receive a service call request sent by the third-party integrated system through the long connection service proxy end, the service call request carries a third-party integrated system identifier, the long connection service proxy end is used for distributing corresponding functions in a service form after packaging the long connection function end, and the specified functions are provided for the third-party integrated system for use through a service interface form, namely, the specified functions are provided for an external integrated system for use through the service interface form. And after the identity authentication of the third-party integrated system identifier is successful through the long connection server cluster by the long connection service proxy, the corresponding service instance is called according to the third-party integrated system identifier. The long connection service proxy terminal is a package of a specific function service terminal, performs service package aiming at the interaction function of the data center, and other data centers are not directly connected to the long connection cluster of the data center and interact through service call. The long-connection service proxy end mainly performs identity authentication of data center interaction and processing of data center interaction matters. The long connection server cluster has an automatic keep-alive function of a service node, for example, the service node is managed through a ZooKeeper, the ZooKeeper is a distributed type, the distributed application program coordination service of open source codes is realized by Chubby of Google, and the ZooKeeper is an important component of Hadoop and Hbase. It is a software providing a consistency service for distributed applications, the provided functions include: configuration maintenance, domain name service, distributed synchronization, group service, etc. When a service node is disconnected, the service node is automatically removed from the cluster, and the connected client is automatically transferred to other service nodes. For example, after a certain service node abnormally terminates the service, the server cluster automatically excludes the node from continuing to serve the user, the original client connected to the node automatically initiates a reconnection request after detecting the service interruption, and the server redistributes the available service nodes for access, thereby achieving the effect of automatically recovering the connection. The server cluster supports the thread expansion of resources, namely, the clients which can be accessed by the server cluster simultaneously also follow the linear expansion, namely, the clients which are simultaneously served can achieve high concurrency, the service node supports the network link multiplexing technology, and a single service node can achieve high concurrency. Meanwhile, the long connection server cluster also has a service instruction processing function, and can realize instruction receiving processing, instruction issuing processing and instruction forwarding processing. For example, the third party integrated system may be a subsystem of the current integrated system, for example, in a certain government engineering system, the current integrated system may be a national level heterogeneous system, and the third party integrated system may be a next-level provincial level heterogeneous system, where each integrated system includes a plurality of sub-enterprise systems, and each sub-enterprise system is provided with a corresponding long connection client. When the long connection server cluster receives a service call request sent by the third-party integrated system through the long connection service proxy, the long connection server cluster can call a corresponding service instance according to the third-party integrated system identifier after the identity authentication of the third-party integrated system identifier is successful according to the third-party integrated system identifier carried in the service call request. Therefore, the security authority verification and control are carried out on different instructions through the instruction identification and the instruction type, the service security during instruction execution and the compliance of data exchange between the heterogeneous systems of enterprises can be ensured through the identity verification, and the data transmission between the heterogeneous systems of the system is realized safely, stably and efficiently.
In one embodiment, the step of calling the corresponding service instance according to the client identifier includes:
and obtaining version information corresponding to the client.
And calling the service instance of the corresponding version according to the version information.
When the server receives a request or a long connection instruction sent by the client, the server performs identity authentication on the client identifier, and after the authentication is successful, the server can call a corresponding service instance according to the client identifier. Specifically, the server may obtain version information corresponding to the client, and the server invokes a service instance of a corresponding version according to the version information. The long-link instruction comprises an instruction identification, an instruction type, a protocol version, a serial number, a data packet ID, a source ID, a target ID and an instruction load. The instruction identification refers to a specific instruction identification number, the instruction type can comprise a server instruction, a function end instruction and a client instruction, and the server can control the security authority of the instruction by combining the instruction identification with the instruction type. Version information refers to a protocol version, i.e., a protocol version supported by instructions, implementing a client instruction compatibility policy, and a low-version client cannot execute high-version instructions. The serial number refers to the instruction serial number, the serial number can be recycled, a maximum value can be set, the instruction retransmission is prevented, and the system automatically discards the expired instruction. The data packet ID is used for identifying a unique data packet, and a response message to the data packet returns the data packet ID and can be used for tracking a data flow processing link. The source ID refers to an instruction (server, function, or client) issued from which end. The target ID or template ID refers to which end process (server, function or client) the instruction is directed to. Instruction load refers to specific data carried by an instruction. For example, when the server receives the instruction sent by the client, the server may obtain version information corresponding to the client, where the version information is version 1, and then the server invokes a service instance corresponding to the corresponding version 1 according to the version information. For example, instruction a includes version 1 carrying parameters c1, c2, and c3. Version 2 is added with parameter c4, i.e. instruction B contains version 2 carrying parameters c1, c2, c3, c4. The high-version instruction, i.e. instruction B, has added parameters, i.e. the functional effect that version 2 needs to achieve in instruction B is different, and the original logic may have been modified, so that the client that originally received the low-version instruction a cannot execute the high-version instruction B. The high version instruction may be a new instruction and the low version client cannot identify and process the high version of the new instruction. Therefore, the server side provides the specified functions corresponding to different versions for the client side to use through the interface mode, the specific service instance of the corresponding version can be called according to the version instruction, and the server side can also send the instruction of the corresponding version according to the version of the client side so as to realize the compatibility of different versions.
