The embodiment of the application provides a resource query processing method, a device, a computer device and a storage medium, which aim to solve the technical problem of how to process a RD when encountering resource links of RCD device resources in the RD and the query method is set as a recursive query. The following will specifically describe the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems by means of examples and with reference to the accompanying drawings. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. It should be noted that, in the resource query processing method provided by the present invention, the execution body is an RD, where the RD may be a computer device, or a resource query processing apparatus, where the apparatus may be implemented in a manner of software, hardware, or a combination of software and hardware to be part or all of resource query processing.
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In one embodiment, fig. 2 provides a method for processing a resource query, and this embodiment relates to a specific process of processing, by an RD, a first resource query request message when a query manner in the first resource request is a recursive query. As shown in fig. 2, the method includes:
s101, receiving a first resource query request message; the first resource query request message comprises a query mode and a query condition.
In this embodiment, the first resource query request message is a request sent by the querying end to the RD, and is used for querying the device resource required by the user. For example, assuming that the certain RCD is a luminaire, the first resource query request message may be to obtain attribute information of the luminaire, for example: the color rendering index, color rendering temperature, stroboscopic information of the lamp and the like. Wherein the first resource query request message can comprise a query mode and a query condition, and the query mode represents a characteristic attribute query, a recursion query, a link query and the like; the characteristic attribute query only obtains the value of the characteristic value attribute in the resource, for example, when the thermometer resource is queried, only obtains the value of the temperature attribute, and other common attributes do not query. The query conditions represent query conditions that the RD needs to follow when querying using a specified query format, for example: the query condition may be a type, a query range, a query time period, etc., and in this embodiment, the query mode and the query condition of the first resource query request message are not limited.
For example, the format of the first resource query request message may be a format of a constrained application protocol (The Constrained Application Protocol, coAP) request message, and the query mode and the query condition may be set in a query portion of the first resource query request message.
S102, inquiring a resource file according to the first resource inquiry request message, and acquiring resource information corresponding to the first resource inquiry request message; the resource file includes the release resource information of the RD and the release resource information of the RCD.
The resource file is stored in the RD, and includes a file of release resource information of the RD and release resource information of the RCD, where the release resource information of the RD and the release resource information of the RCD may be resource information that can be queried by each device, and the release resource information may include a resource type, an address, and the like of the device, which is not limited in this embodiment. The resource file may be in an oic/res format, the resource type of the published resource information of the RD may be oic.wk.rd, and the resource type of the published resource information of the RCD may be oic.wk.res.
In this embodiment, the RD searches the resource file for the resource information meeting the query condition according to the query mode in the first resource query request message, for example, the query mode in the first resource query request message is a recursive query, and if the query condition is a lamp, the RD searches the resource file for the resource information with all the resource types being the lamp in the recursive query mode.
S103, if the query mode is recursive query and the resource information comprises the resource link of the RCD, a preset processing mechanism is adopted to process the first resource query request message.
In this embodiment, if the query manner carried in the first resource query request message is recursive query and the obtained resource information corresponding to the first resource query request message includes the resource link of the RCD, a preset processing mechanism is adopted to process the first resource query request message. Wherein the resource link of the RCD represents an acquisition path of resource information issued by the RCD, for example: the resource links of the RCD may include resource addresses, types, interfaces available for use, IP addresses, etc., which are not limited in this embodiment. The preset processing mechanism represents a processing rule of the RD to the first resource query request message, which is preset according to the requirement, namely: and the RD processes each request when receiving different first resource inquiry request messages.
In this embodiment, a corresponding processing mechanism may be specified in advance, and when a query manner is a recursive query and the resource information includes a resource link of an RCD, processing may be performed according to the processing mechanism, for example, the processing mechanism may be that the query manner is a recursive query and when the resource information includes a resource link of an RCD, the first resource query request message is directly ignored, or the resource link of the RCD is fed back to the query end, or the corresponding RCD is directly accessed to obtain a query resource, or the like.
According to the resource query processing method provided by the embodiment, the RD searches the resource information meeting the query condition in the resource file according to the query mode in the first resource query request message, and if the query mode is recursive query and the queried resource information comprises the resource link of the RCD, the first resource query request message is processed by adopting a preset processing mechanism.
Optionally, in one embodiment, step S103 "the processing the first resource query request message by using a preset processing mechanism" includes: discarding the first resource query request message.
In this embodiment, if the RD processes the first resource query request message according to the preset processing mechanism, and if the query mode is recursive query and the queried resource information includes the resource link of the RCD, the RD discards the first resource query request message, i.e. directly ignores the first resource query request message. Thus, after the inquiring end can not receive the response information returned by the RD for a long time, the inquiring end considers that the network does not have the needed resources.
In one embodiment, fig. 3 provides a method for processing a resource query, which relates to a processing mechanism of RD if the query mode is a recursive query and the queried resource information includes a resource link of RCD. As shown in fig. 3, the "processing the first resource query request message by using a preset processing mechanism" includes:
s201, according to the resource information, a first response message is acquired.
The first response message is used for representing a resource query result.
In this embodiment, if the resource information includes resource connection of the RCD, the resource connection of the RCD may be used as a query result to generate the first response message, or if the resource information includes specific information of the query resource, the specific information of the query resource is used as a resource query result to generate the first response message. For example: the first resource query request message is: the color rendering index and color rendering temperature of the lamp are obtained, and the first response message may include a specific color rendering index and color rendering temperature of the lamp, or the first response message may include an identifier, an address, an inquiry interface, and the like of the lamp, which is not limited in this embodiment.
Optionally, one implementation of the step S201 includes: changing the query mode into a link query mode; acquiring the resource link of the RCD according to the resource information by adopting the link inquiry mode; and carrying the resource link of the RCD in the first response message.
In this embodiment, since the resource link cannot be obtained by the recursive query method, the query method needs to be changed to the link query method, for example, the recursive query method (oic.if.b) may be changed to the link query method (oic.if.ll), the resource link of the RCD may be obtained by the link query method, and the resource link of the RCD may be carried in the first response message. The resource link of the RCD represents a link path of the RCD for issuing resource information, for example, if the RCD is a luminaire a, the resource link of the RCD may be a luminaire a device identifier, a resource address, a type, an available interface, an IP address, etc., and the RD may generate the first response message according to the luminaire a device identifier, the resource address, the type, the available interface, the IP address, etc.
Optionally, the first response message is a redirection message, where the redirection message is used to instruct the querying end to acquire the required resources from the RCD. After the query terminal receives the first response message, the query terminal obtains the required resources from the corresponding RCD according to the first response message.
S202, the first response message is sent to a query end.
In this embodiment, the RD sends the first response message to the query end, where the query end may perform corresponding processing according to the content and type of the first response message. For example, if the first response message includes a resource link of the resource-constrained device a, and the first response message is a common response message, the querying end may continue to query the resource-constrained device a for the required resource, or may not query the resource-constrained device a for the required resource. If the first response message includes a resource link of the resource-constrained device a and the first response message is a redirection message, the querying end must query the resource-constrained device a for the required resource.
According to the resource query processing method provided by the embodiment, the RD acquires the first response message according to the resource information corresponding to the first resource query request message, sends the first response message to the query terminal, and informs the query terminal of the query result, so that the technical problem of how the RD processes when encountering resource links of the RCD equipment resources in the RD and the query method is set as recursive query is solved.
In one embodiment, fig. 4 provides a method for processing a resource query, and this embodiment relates to a specific process of obtaining, by an RD, a first response message according to resource information. As shown in fig. 4, S201 includes:
S301, determining a target RCD according to the resource information.
In this embodiment, since the resource information includes the resource link of the RCD, the RD may determine the target RCD according to the resource link of the RCD, for example, if the resource link of the RCD includes information such as an identifier, an address, an interface, etc. of the RCD, the target RCD may be determined according to the identifier, the address, the interface, etc. of the RCD.
It should be noted that, the resource information may include resource links of one RCD or resource links of a plurality of RCDs, and the determined target RCD may include one RCD or a plurality of RCDs.
S302, a second resource query request message is sent to the target RCD; the second resource query request message is used for indicating the target RCD to query the resources required by the query end.
Based on the target RCD determined in step S301, the RD sends a second resource query request message to the target RCD, where the second resource request is used to instruct the target RCD to query the resource required by the querying end, that is, to query the resource requested by the first resource query request message.
For example: assuming that the target RCD is the lamp A, the RD sends a second resource query request message to the lamp A to acquire the color rendering index of the lamp A, and the lamp A returns the display index of the lamp A to the RD when receiving the request.
If the target RCD includes a plurality of RCDs, the RD sends a second resource query request message to each RCD, respectively.
S303, receiving a second response message sent by the target RCD; the second response message includes the resources required by the querying end.
In this step, after receiving the second resource query request message, the target RCD feeds back, according to the second resource query request message, the second response message carried by the required resource information to the RD. For example, if the target RCD is a refrigerator and the second resource query request message is used for querying the temperature of the refrigerator, the refrigerator carries the current temperature of the refrigerator in the second response message and feeds the second response message back to the RD.
S304, generating the first response message according to the second response message.
Based on the second response message sent by the target RCD and received by the RD in step S302, the first response message is generated according to the second response message, and since the second response message is the result of the query of the target RCD according to the second resource query request message sent by the RD, the first response message generated according to the second response message includes the resources required by the query end. The manner of generating the first response message according to the second response message may be, for example, a format required for converting the second response message into the first response message, or other manners, which are not limited in this embodiment.
Considering that the resource query request sent by the query end is more than asking for resources from one RCD in some cases, optionally, if there are multiple target RCDs, the generating the first response message according to the second response message includes: and generating the first response message according to the second response message sent by each target RCD. When a plurality of target RCDs exist, the RD sends corresponding second resource query request messages to the plurality of target RCDs, each target RCD returns the result queried according to the second resource query request message to the RD as a second response message after receiving the second resource query request message, and the RD integrates the second response messages sent by all the target RCDs to generate the first response message. Thus, the RD can query the resources required by the querying side regardless of whether the source of resources required by the querying side is a target RCD or a plurality of RCDs.
According to the resource query request method provided by the embodiment, the RD determines the target RCD firstly according to the resource information, then sends the second resource query request message for indicating the target RCD to query the resources required by the query end to the target RCD, and generates the first response message according to the second response message which is fed back by the target RCD and comprises the resources required by the query end, so that the RD can still acquire the resources required by the query end when the query mode is recursive query and the resource information comprises the resource links of the RCD, and the query efficiency is improved.
The embodiment of the application also provides a method for processing the published resource information of the RD, optionally, if the query mode is a recursive query and the published resource information of the RD is included in the resource information, acquiring the resource meeting the query condition by adopting the recursive query mode.
In this embodiment, if the query portion of the first resource query request message is if=oic.if.b and oic.wk.rd, the query mode is a recursive query, and the corresponding resource information includes the published resource information of RD, and then a recursive query mode is adopted to obtain the resource meeting the query condition.
In one embodiment, fig. 5 provides a resource query processing method, and this embodiment relates to a specific process of the RCD publishing its queriable resource to the RD. As shown in fig. 5, the method further includes:
s401, receiving a resource release request sent by an RCD of a resource to be released; the resource release request comprises the equipment identification and attribute information of the RCD of the resource to be released.
In this embodiment, when the RCD that is to issue a resource needs to issue the resource, the RD may be selected first, and then a resource issue request is sent to the RD. The resource release request sent by the RCD of the resource to be released includes its own device identifier and attribute information, where the device attribute information includes a resource address, a type, an available interface, an IP address, and the like, which is not limited in this embodiment.
Alternatively, when the RCD that is to issue the resource selects the RD, a broadcast request may be sent first, where the broadcast request is used to indicate that the RCD needs the resource to issue, and a response message of the received RDs, and one or more RDs are selected from the RDs that are to issue. It should be noted that one RCD may determine one or more RDs, and one RD may also correspond to one or more RCDs.
And S402, authenticating the RCD of the resource to be issued according to the resource issuing request.
In this embodiment, the RD authenticates the RCD of the resource to be issued that sends the request according to the resource issuing request, where authentication indicates whether the RCD of the resource to be issued that sends the request has authority to issue the resource on the RD, and the manner in which the RD authenticates the RCD of the resource to be issued may be, for example, by identifying whether the RCD of the resource to be issued is a device that has already been bound to the RD, or may be other authentication manners, which is not limited in this embodiment.
And S403, if the authentication is passed, storing the release resource information of the RCD of the resource to be released into the resource file according to the resource release request.
Based on the result of authenticating the RCD of the resource to be issued in the step S402, if the authentication result is passed, the RD saves the resource information issued by the RCD of the resource to be issued in the own resource file, where the resource information issued by the RCD of the resource to be issued may be any information of the RCD of the resource to be issued, for example: parameter information, usage detail information, and the like, which is not limited in this embodiment.
According to the resource query processing method provided by the embodiment, the RD authenticates the corresponding RCD of the resource to be issued according to the resource issuing request by receiving the equipment identifier and the attribute information resource issuing request of the RCD of the resource to be issued, if the authentication is passed, the issued resource information of the RCD of the resource to be issued is stored in the resource file, and in the method, the RD authenticates the RCD of the resource to be issued first, and if the authentication is passed, the issued resource information is stored, so that the RD does not process the resource request of the RCD without authority when helping the RCD to process the resource discovery request, and the security of the RD processing process when the RCD equipment resource is linked in the RD is met, and the query method is set as the security of the RD during recursive query.
It should be understood that, although the steps in the flowcharts of fig. 2-5 are shown in order as indicated by the arrows, these steps are not necessarily performed in order as indicated by the arrows.
