Background
Data pushing systems are services/software for transmitting data from one system or application to another system or application in real-time or in bulk, which are commonly used to address data synchronization, information transfer, and real-time updates. Data push systems may transfer data between different applications, servers, devices or networks, which systems typically establish a connection between a source and a target and transfer data based on a communication protocol such as HTTP (Hypertext Transfer Protocol ), webSocket, MQTT (Message Queuing Telemetry Transport, message queue telemetry transport), etc.
Subscription to log data refers to a process in one system or application that allows a user or other system to obtain and receive log data generated by the system in real-time. In general, the log generated by the system records information such as running state, event, error and warning of the system, and is very important for fault detection, performance monitoring, security audit and the like. Through log data subscription, a user or other system may subscribe to a log type or log source of interest in order to receive up-to-date log data in real-time.

The following detailed description of specific embodiments, features and effects according to the present invention is provided with reference to the accompanying drawings and preferred embodiments.
Referring to fig. 1, an embodiment of the present application provides a log data subscription management method of a data push system, including the following steps:
s1, creating a message queue and defining a message format of log data;
s2, the data pushing system establishes bidirectional safety connection with the message queue;
s3, the data pushing system establishes one-way safety connection with the subscribing user;
s4, the subscribing user establishes bidirectional safety connection with the message queue;
s5, the subscribing user sends a log subscription request to the data pushing system;
s6, the data pushing system performs authorization verification on the log subscription request, and if verification is passed, log data are matched according to the log subscription request and are sent to a message queue;
s7, the message queue performs secondary verification on the subscribing user, and if verification is passed, the log data is sent to the subscribing user;
s8, the subscribing user receives the log data and sends a confirmation message to the message queue.
Specifically, efficient log data subscription management is realized through message queues, firstly, proper message queues such as RabbitMQ, apache Kafka, activeMQ and the like are selected, and then the message format of log data such as JSON, XML and the like is determined; secondly, a safe connection is established among the data pushing system, the message queue and the subscribing user, wherein the safe connection indicates that the communication connection among the three is protected safely and cannot be easily invaded by viruses and the like; wherein, the bidirectional safety connection means that the two parties can perform bidirectional network intercommunication, and the unidirectional safety connection can only perform unidirectional network communication; in this embodiment, two-way network interworking can be performed between the data push system and the message queue, and between the subscriber and the message queue, while only one-way network interworking can be performed between the data push system and the subscriber, i.e.: the data push system can only receive the network request of the subscriber, but can not directly send log data to the subscriber through the data push system; the subscribing user can send a confirmation message to the message queue after receiving (processing) the log data, and inform the message queue that the log data serving as the message is correctly received (processed), and only after receiving the confirmation message of the subscribing user, the message queue marks the message as consumed and deleted, so that the subscribing user can be ensured to process only the latest message, and the time difference caused by processing the outdated old message is avoided, thereby ensuring the real-time performance and the correctness when the subscribing user receives the log data.
As shown in fig. 2, in one embodiment provided in the present application, after the subscriber establishes a bidirectional secure connection with the message queue, a message subscription is created between the subscriber and the message queue, and a message monitor is established, which specifically includes the following steps:
s11, configuring an API in a message queue;
s12, a subscribing user establishes a subscription relation with a message queue through an API;
s13, setting a message monitor in a message queue, wherein the message monitor comprises a callback function;
s14, the message monitor receives the message and processes the message;
and the message queue sends the message as a callback parameter to the callback function for processing.
Specifically, in the embodiment of the application, a subscription user establishes a subscription relationship through an API (interface), then monitors a message queue by establishing a message monitor in the message queue, and when a new message arrives at the queue, the subscription user automatically receives a notification and further receives and processes the message; the callback function is arranged in the message queue, so that a mechanism for asynchronously processing the message can be realized, and the processing of the message and other logic are decoupled; through the callback function, the self-defined operation can be triggered when the message arrives, and the message does not need to be processed immediately, so that the data push system can process a plurality of messages at the same time, and the concurrency performance and the response capability of the system are improved.
In one embodiment provided by the application, when the data pushing system establishes a one-way secure connection with the subscribing user, the data pushing system generates a unique API key for the subscribing user, and the API key is used for verifying the identity of the subscribing user.
In one embodiment provided in the present application, when the subscriber establishes a bidirectional secure connection with the message queue, the message queue configures an access control list, where the access control list is used for performing a secondary authentication on the subscriber.
Further, configuring the access control list includes assigning permissions to the subscribing users and writing the permissions into the access control list.
Specifically, regarding Access Control Lists (ACLs): the message queue typically supports setting access control lists to limit access rights for subscribing users, which may be configured by ACLs to allow or deny access to the message queue to specific users or groups of users, who need to provide identity information to verify their access rights, and use the message queue to the extent they are authorized.
In one embodiment provided by the application, the data pushing system sets a timestamp in the log data, where the timestamp is used for performing consistency verification on the log data.
Specifically, the data pushing system may record and mark the time of each piece of pushed log data by setting a time stamp; the timestamp refers to the identification of a specific moment, and can be a number, a date and time format or other forms; the time stamp has the functions of data sequencing, data synchronization, data delay monitoring, data validity verification and the like.
As shown in fig. 3, in one embodiment provided in the present application, the subscribing user performs integrity check on the log data, including the following steps:
s21, subscribing users perform data acquisition on the log data to acquire check data;
s22, calculating a first checksum of the check data by adopting a checksum algorithm;
s23, the data pushing system blocks the log data to obtain log data blocks;
s24, calculating the log data block by adopting a checksum algorithm to obtain a second checksum;
s25, comparing the first checksum with the second checksum to obtain a comparison result;
s26, verifying the integrity of the log data according to the comparison result.
Further, the checksum algorithm includes one or more of MD5, SHA-1, and SHA-256.
In one embodiment provided by the application, the data pushing system uses regular expressions to match the log data.
Further, an index and a caching mechanism are built in the data pushing system, and the index and the caching mechanism are associated with the regular expression.
In summary, the security of the log data transmission process is ensured by establishing the secure connection and performing authorization verification and identity verification; the integrity of the data after the data transmission is ensured through the integrity check of the data; the timeliness and the synchronism of the data are ensured by establishing a message confirmation mechanism and a message monitor; the horizontal expansion capability, stability and scalability of the data push system are improved by establishing a message queue.
