配置route

spring:  
  cloud:  
    gateway:  
      routes:  
        - id: test_route  
          uri: https://www.baidu.com/  
          predicates:  
          - Query=url,baidu  
        - id: qq_route  
          uri: https://www.qq.com/  
          predicates:  
          - Query=url,qq

测试

浏览器地址栏输入内容，并且回车

http://localhost:88/hello?url=qq

会被网关映射到

https://www.qq.com/hello

可以尝试下面的测试，这将跳转到baidu的搜索首页


http://localhost:88/s?url=baidu
