This article will explain in detail what is the latest gateway flow control component of zuul integration Sentinel. The content of the article is of high quality, so the editor shares it for you as a reference. I hope you will have a certain understanding of the relevant knowledge after reading this article.

I. explanation

Sentinel gateway traffic control supports traffic control for different routes and custom API packets, and for request attributes (such as URL parameters, Client IP,Header, etc.). Sentinel 1.6.3 introduces the support of gateway traffic control console. Users can view API Gateway real-time route and custom API packet monitoring, manage gateway rules and API packet configuration directly on the Sentinel console.

Second, functional access 1. The gateway adds sentinel-related jar dependencies on com.alibaba.cloud spring-cloud-starter-alibaba-sentinel com.alibaba.csp sentinel-datasource-nacos com.alibaba.cloud spring-cloud-alibaba-sentinel-gateway2. Sentinel configuration of gateway zuul spring: # sentinel dynamic configuration rules cloud: sentinel: zuul: enabled: true order: pre: 2000 post: 500 error:-100 filter: enabled: false datasource: # current limit ds1: nacos: server-addr: ${zlt.nacos.server- Addr} dataId: ${spring.application.name}-sentinel-gw-flow groupId: DEFAULT_GROUP rule-type: gw-flow # api grouping ds2: nacos: server-addr: ${zlt.nacos.server-addr} dataId: ${spring.application.name}-sentinel-gw-api-group groupId: DEFAULT_ GROUP rule-type: gw-api-group

The rule data source that binds gw-flow (current limit) and gw-api-group (api grouping) is nacos and specifies the corresponding dataId and groupId on nacos.

3. Nacos rule configuration 3.1. Current limiting configuration gw-flow

Data ID:api-gateway-sentinel-gw-flow

Group:DEFAULT_GROUP

Configuration content:

[{"resource": "user", "count": 0, "paramItem": {"parseStrategy": 3, "fieldName": "name"}}, {"resource": "uaa_api", "count": 0}]

Rule 1: all user requests are intercepted (qps=0) as long as the parameters with name are intercepted. User is the routeId rule on zuul routing configuration. All requests with uaa_api grouped by 2:api are intercepted (qps=0).

3.2. Api packet configuration gw-api-group

Data ID:api-gateway-sentinel-gw-api-group

Group:DEFAULT_GROUP

Configuration content:

[{"apiName": "uaa_api", "predicateItems": [{"pattern": "/ user/login"}, {"pattern": "/ api-uaa/oauth/**", "matchStrategy": 1}]}]

All the api configured above to meet the rules are grouped into uaa_api grouping rule 1: precise matching / user/login grouping rule 2: prefix matching / api-uaa/oauth/**

4. Gateway zuul startup parameters

You need to add-Dcsp.sentinel.app.type=1 startup to the original startup parameters of the access side to mark your service as API Gateway. When you connect to the console, your service will be automatically registered as a gateway type, and then you can configure gateway rules and API grouping on the console, for example:

Java-Dcsp.sentinel.app.type=1-jar zuul-gateway.jar III. Sentinel console management

API Management (grouping)

Gateway traffic control rules

4. Test current-limiting api1. Test current limit rule 1

All user requests are intercepted (qps=0) as long as the parameter has name.

You can access api without adding name parameter

After the parameter name, the request is intercepted.

two。 Test current limit rule 2

All requests grouped by api as uaa_api are intercepted (qps=0)

Prefix matching / api-uaa/oauth/**

Precise matching / user/login
