In an embodiment, the gateway device 1 may be a router, a switch, or the like, or may be a gateway device formed by a mobile phone, a notebook computer, a desktop computer, or the like.
For clarity of description of the present embodiment, the terms involved are defined as follows:
link isolation: the designated instance nodes of all or part of services on the primary micro-service request link are isolated into an independent environment, and each request only goes to the instance nodes in the service isolation environment and does not access the instance nodes outside the service isolation environment when accessing the services.
And (3) isolating the environment: a logically or physically separate suite or portion of a system for restricting service instances accessible to requests.
Please refer to fig. 2, which is a schematic view of a data routing system of an isolation environment 30 according to an embodiment of the present application, including: terminal 20, gateway device 1 and isolation environment 30, wherein:
the terminal 20 may be a mobile phone, a computer, etc. of a user, and the user may send a data request for accessing a certain service through a client installed in the terminal 20.
The gateway device 1 may be the gateway device 1 shown in fig. 1, which may first receive a data request issued by the terminal 20 by the gateway device 1, the gateway device 1 forwarding the data request to a suitable target serving node.
The isolation environment 30 may include a plurality of services, and in fig. 2, 2 services a and 2 services B are taken as examples, each service may include a plurality of service nodes, for example, a service a includes n nodes (n is a positive integer), and a service B includes m nodes (m is a positive integer).
In an actual scenario, a user may send a data request to any service in the isolation environment 30 through the terminal 20, where the data request may specify a target service to be accessed and target node information, and the gateway device 1 forwards the data request to a corresponding target service node based on a routing tag in the data request, and forwards data returned by the target service node to the terminal 20. Enabling data routing between the terminal 20 and the isolation environment 30.
Please refer to fig. 3, which is a data routing method according to an embodiment of the present application, which may be performed by the gateway apparatus 1 shown in fig. 1 and may be applied in the data routing scenario shown in fig. 2 to route a data request to a target service node in a specified isolation environment 30. The method comprises the following steps:
step 301: receiving a data request, wherein the data request comprises: a routing label of the target service that the request accesses.
In this step, when the user wants to access a certain service through the terminal 20, for example, the user wants to access a certain shopping platform, the shopping platform is a target service, and a data request may be sent through a mobile phone or a computer of the user, where the data request may carry a routing tag of the shopping platform that needs to be accessed, and the routing tag may record identification information of the target service and specified node information to specify the isolation environment 30 that needs to be accessed.
In an embodiment, the data request may be an HTTP request, and the routing tag may include a key value pair, for example, a tag, where different values of the tag may identify different service nodes, and may be specifically set based on actual requirements. For example, tag 1 may indicate that the user wants to designate a node 1 accessing service a, tag 2 may indicate that the user wants to designate a node 2 accessing service a, and so on. A routing tag may be placed in the HTTP request header.
In one embodiment, the data request may also be a remote call request, such as an RPC request, in which case the routing tag may be a special field in the RPC Context that specifies the isolation environment 30 to which the request is to be accessed.
Step 302: and acquiring all nodes under the target service in a resource database.
In this step, after receiving the data request sent by the terminal 20, the gateway device 1 analyzes the data request, obtains the target service specified in the routing label from the data request, and then extracts all nodes under the target service, for example, all service nodes under the shopping platform, from the resource database.
In an embodiment, the gateway device 1 may obtain the routing node through a Uniform Resource Identifier (URI), so as to obtain all nodes corresponding to the target service.
Step 303: and selecting a target node corresponding to the routing label according to all the nodes and a preset isolation service library.
In this step, the gateway device 1 may filter all nodes and isolated nodes in a preset isolated service library according to the routing tag in the data request, and find a target node of the specified target service. The screened target nodes can prevent a certain data request from going to a service node in the non-isolated environment 30, and the accuracy of data routing is guaranteed.
Step 304: and sending the data request to the target node.
In this step, after determining the target node, the gateway device 1 may initiate an access request to the specified target node based on the data request from the terminal 20, and forward result data returned by the target node to the user terminal 20.
The data routing method receives a data request sent by a request terminal 20 through a gateway device 1, acquires all nodes of a target service to be accessed by the data request from a resource database, screens out target nodes meeting the requirement of a routing label based on all the nodes of the target service and isolation nodes recorded in an isolation service library, and finally forwards the data request to the target nodes so that the target nodes can return corresponding data to the request terminal 20. In this way it is achieved that the gateway device 1 can send the request to a service node in a particular isolation environment 30. Ensuring that a certain request cannot go to a service node in the non-isolated environment 30, expanding the isolation mode of the data link request and facilitating the verification of new functions in the software product development and test process.
Please refer to fig. 4, which is a data routing method according to an embodiment of the present application, which can be executed by the gateway apparatus 1 shown in fig. 1 and can be applied in the data routing scenario shown in fig. 2 to route a data request to a target service node in a specified isolation environment 30. The method comprises the following steps:
step 401: receiving service isolation configuration information, pulling service node information to be isolated according to the configuration information to form an isolation environment 30, and recording the service node information to be isolated in an isolation service library.
In this step, a research and development worker may access the environment isolation configuration background of the gateway device 1, set information such as a service node to be isolated, and after receiving the configuration information, the gateway device 1 pulls information of the service node to be isolated, forms the isolation environment 30, and records the information of the service node to be isolated in the isolation service library.
Step 402: receiving a data request, wherein the data request comprises: a routing label of the target service that the request accesses. See the description of step 301 in the above embodiments for details.
Step 403: and judging whether the target service is in the isolated service library. If so, go to step 404, otherwise, the data request may be denied.
In this step, the isolated service library records a plurality of services configured in advance in the isolated environment 30 and node information corresponding to each service, for example, 2 services a and B are taken as examples in fig. 2, and the isolated service library records information of n nodes included in the service a and information of m nodes included in the service B. After receiving the data request, first determining whether the target service specified in the data request is in the isolated service library, if so, entering step 404, otherwise, indicating that the data request is illegal, rejecting the data request, and avoiding the illegal request from entering the isolated environment 30. For example, assuming the data request specifies that the target service is service A in the isolated service library, step 404 is entered.
Step 404: if the target service is in the isolated service library, all nodes under the target service are obtained in the resource database, which is described in detail in the foregoing embodiment for step 302.
Step 405: and selecting the node specified by the routing label from all the nodes.
In this step, after determining that the target service is a service in the isolation environment 30, the node specified by the data request is selected from all nodes of the target service based on the routing tag of the data request. For example, if the key value pair tag in the routing label is 1, the designated node 1 is selected from all the nodes of the service a.
Step 406: it is determined whether the designated node is in the isolated service library. If yes, go to step 407, otherwise, go to step 408.
In this step, although the node specified in the data request of the user is the node of the target service, the specified node is not necessarily in the isolated environment 30, for example, if the key value pair tag in the routing tag is 1, the specified node is the node 1 of the service a, and the node is in the isolated environment 30, the process proceeds to step 407. In addition, assuming that the service a has N nodes in common, where N nodes are in the isolated environment 30, and the remaining N-N nodes are not in the isolated environment 30, and the node specified in the routing tag is the node h of the service a, and the node h is in the N-N nodes, it indicates that the node h is not in the isolated service library, and step 408 is entered.
Step 407: the designated node is taken as the target node, and the process proceeds to step 409.
In this step, if the designated node is in the isolated service library, it indicates that the designated node is a legitimate isolated node, and it can be used as a target node.
Step 408: and acquiring a default node of the target service from the isolated service library, taking the default node as the target node, and entering step 409.
In this step, if the designated node is not in the isolated service library, for example, the designated node h is not in the isolated service library, it indicates that the node h is not a node in the isolated environment 30, and in order to ensure that the data request reaches the isolated environment 30 accurately this time, the node h is not taken as a target node, but a default node preset for the target service is obtained from the isolated service library, and the default node is taken as the target node, so that it is ensured that the data request initiated by the isolated environment 30 does not go to a service node in the non-isolated environment 30, and it is convenient for development and testers to verify new functions.
Step 409: and sending the data request to the target node. See the description of step 304 in the above embodiments for details.
The data routing method realizes link and environment isolation in the gateway device 1 based on the routing label. The gateway device 1 can send a request to a service node in a particular isolation environment 30 by simply specifying a routing tag in the HTTP request header when the client initiates the request. The requests initiated by the box isolation environment 30 are ensured not to go to the service nodes in the non-isolation environment 30, and development and testing personnel can verify new functions and troubleshoot problems conveniently. The link and the environment isolation of the internal service are realized in the gateway device 1, so that the gateway device is communicated with the external gray level flow, the environment isolation of the whole link is realized, and the problem that the external gray level flow cannot be connected with the internal micro service and the RPC service in series is solved. And because the whole link uses the isolation label, the internal micro-service and RPC service call use the same standard isolation strategy.
