gateway predicate

 

有这几种predicate，试验几个：

 

1.带header的 - HeaderRoutePredicateFactory：

spring:
  application:
    name: cloud-gateway
  cloud:
    gateway:
      discovery:
        locator:
          enabled: true    #开启动态路由功能
      routes:
        - id: host_route
          uri: lb://cloud-payment-service
          predicates:
            - Path=/payment/get/*
            - After=2021-05-28T09:11:26.769+08:00[Asia/Shanghai]
            - Header=is-ipv6, \d+

测试添加header: is-ipv6:222正常返回：

 测试添加is-ipv6=ccc或者不添加，不正常返回：

 

 

2. 带cookie的：

spring:
  application:
    name: cloud-gateway
  cloud:
    gateway:
      discovery:
        locator:
          enabled: true    #开启动态路由功能
      routes:
        - id: host_route
          uri: lb://cloud-payment-service
          predicates:
            - Path=/payment/get/*
            - After=2021-05-28T09:11:26.769+08:00[Asia/Shanghai]
            - Header=is-ipv6, \d+
            - Cookie=ipv4, \d+

测试：

带cookie成功：

 

 

 不带cookie失败：
