网关处理逻辑

1. 网关优先匹配global的路由,确定路由分组
2. 按照路由顺序匹配分组里面的子路由
3. 执行路由过滤器配置

路由配置说明

#route.yaml
routes:
  - id: 196105db9a384d7a93f8102ae46684cb  # 唯一Id
    group: test # 路由分组
    order: 100  # 路由匹配顺序
    global: true # 是否全局路由
    protocol: http # 路由协议
    expressionStr: Path.AntMatch('/replace/**') # 路由匹配表达式
    filterConfigs: # 路由过滤器配置
    - name: rewrite
      param:
        regex: "/replace/(.*)"
        replacement: "/$\\1"
    - name: proxy
      param:
        uri: "lb://test"
instances:
  - host: test
    address: localhost:4843
