Detailed Description

The following examples are given for the detailed implementation and specific operation of the present invention, but the scope of the present invention is not limited to the following examples.

The embodiment provides a technical scheme: a dynamic routing arrangement method based on Spring Cloud Gateway comprises the following steps:

step S1: registering dynamic routing rule information

The service provider provides a service system interface required to be registered, perfects basic service information, arranges resources, and determines the flow direction and arrangement processing requirements of the dynamic route; adding necessary filtering into a dynamic route, wherein the filtering comprises a black and white list, current limiting, fusing and the like, and the filtering is used as a limiting strategy of a service gateway;

step S2: boot load snoop dynamic routing configuration

Starting a Spring Cloud Gateway system, automatically monitoring the configuration of a dynamic route, loading rule information into the Spring Cloud Gateway route, continuously monitoring, and refreshing the route in real time once the route information changes;

step S3: request call gateway

A consumer or a system administrator calls a unified open address of the service gateway, splices the unique code of the service, inputs necessary parameters and sends a request to the service gateway;

step S4: matched route filtering control strategy

The service gateway request path carries a route unique identifier, and is automatically matched with private filtering rules through gateway route identification, the private filtering rules are unique to different gateways, and a global filter has a control function on all service gateways;

step S5: executing dynamic routing choreography flow

In the request processing process of the service gateway, arranging a plurality of routing resources, adapting http resources and groovy resources, converting resource information of different routes, and recording response log information of different resources;

step S6: request return

And after the routing strategy is successfully executed, the service gateway returns service interface data provided by the service provider, records the return information to the log, and the service gateway finishes calling.

In this embodiment, in step S1, the service provider provides a plurality of original resource information, performs arrangement operations on different resources, determines the flow direction of the resource, specifies the service name, the service code, the system to which the service belongs, the service home center, and the service request mode, and completes a basic information registration, that is, the external unique identifier and the special classification of the dynamic route. After the registration is completed, the configuration of the global filter and the private filter is carried out according to the routing arrangement requirement, and the policies such as a black and white list, current limiting, fusing and the like are configured based on the Spring Cloud Gateway routing rule, so that the policy guarantee is provided for the dynamic routing.

In this embodiment, in step S2, once the Gateway system (Spring Cloud Gateway system) is started, dynamic routing information is automatically monitored, where the routing information is obtained from the micro service dynamic configuration service nacos, an external API provided by the nacos is called to complete real-time monitoring of dynamic routing changes, the API provided by the nacos cannot monitor a new problem of the dynamic routing, and a cache region is established in the nacos for this purpose in step S2, and is specially stored with the dynamic routing identification information, and monitors the cache region to complete monitoring of the new routing, that is, to complete real-time monitoring of the dynamic routing configuration. And the dynamic routing information monitoring executes dynamic routing service (dynamic routing service) at the same time, and dynamically adds or modifies new routing information according to the requirement of the routing information by the Spring Cloud Gateway routing rule.

In this embodiment, in step S3, the dynamic routing provides a unified external address, the consumer or the system administrator splices information such as an unique identifier endpoint (i.e., a service code) of the routing request, and inputs a request message, and the routing can analyze routing information including the service code during the request invocation process, and the service code is used as a unique identifier, and enters the dynamic routing arrangement gateway similar to a pass.

In this embodiment, in step S4, when the request enters the dynamic routing, the execution order of each type of filter is specified according to the Spring Cloud Gateway routing rule, and the filter getOrder rewriting method is as follows:

the smaller the return result is, the earlier the return result is, the dynamic routing orchestration gateway respectively executes global IP black and white list filtering, global current limiting processing, analysis routing parameter filtering, global IP dimension current limiting, global application black and white list filtering, authentication filtering, global user dimension black and white list filtering, private service dimension IP black and white list filtering, private service dimension service current limiting filtering, private service + IP combined current limiting filtering, private service dimension service fusing filtering and the like. The black and white list of the IP limits that only some IPs can be called or some IPs cannot be called; in the route parameter analysis, log information is recorded simultaneously by analyzing token, frompip, body and the like, so that the dynamic route calling of later-stage statistics can be conveniently used; the security of application calling is ensured by checking appKey in authentication; in the current-limiting filtering, the phenomenon that the gateway service bearing is exceeded to cause breakdown because multiple requests occur in a short time in the gateway route is prevented; in the fusing filtering, if a certain service is abnormal too much or the request time is too long, a degradation mechanism is executed, and the normal calling of other gateways is ensured.

In this embodiment, in step S5, in the service gateway processing process, after a resource is executed, it needs to process the resource response information, and record the response information in the log, so as to ensure the backup of data before processing, obtain the data stream after response to another resource in the route arrangement, and when the resource is an HTTP resource, use the response data of the previous resource as the entry parameter of the next resource, and complete the invocation inside the route; when another resource is a groovy resource, different results are output according to different logics of the groovy resource script, such as filtering response data or adding identification information to the response data.

In this embodiment, in step S6, after the request Gateway performs filtering and dynamic arrangement, the previously registered service interface return data has changed correspondingly according to the arrangement processing and the requirement of the consumer, and is more safely usable under the protection of the Spring Cloud Gateway system, and the log information is saved while the data is returned after the request is finished.
