**一 开源项目地址**

[https://github.com/cakin24/spring-cloud-code/tree/master/ch17-1/ch17-1-2-gateway][https_github.com_cakin24_spring-cloud-code_tree_master_ch17-1_ch17-1-2-gateway]

**二 核心代码**

server:
      port: 8081
    spring:
      application:
        name: spring-cloud-gateway
    
    # 关键看下面这段，定义了id，uri，Path
    spring:
      cloud:
        gateway:
          routes: #当访问http://localhost:8080/baidu,直接转发到https://www.baidu.com/
          - id: baidu_route
            uri: http://baidu.com:80/
            predicates:
            - Path=/baidu
    
    
    
    
    logging: ## Spring Cloud Gateway的日志配置
      level:
        org.springframework.cloud.gateway: TRACE
        org.springframework.http.server.reactive: DEBUG
        org.springframework.web.reactive: DEBUG
        reactor.ipc.netty: DEBUG
    
    
    management:
      endpoints:
        web:
          exposure:
            include: '*'
      security:
        enabled: false

**三 测试**

1 启动 ch17-1/ch17-1-2-gateway

2 浏览器输入  [http://localhost:8081/baidu][http_localhost_8081_baidu]

页面路由到百度主页

3 浏览器输入  [http://localhost:8081/actuator/gateway/routes][http_localhost_8081_actuator_gateway_routes]

页面显示

[
        {
            "route_id": "baidu_route",
            "route_definition": {
                "id": "baidu_route",
                "predicates": [
                    {
                        "name": "Path",
                        "args": {
                            "_genkey_0": "/baidu"
                        }
                    }
                ],
                "filters": [],
                "uri": "http://baidu.com:80/",
                "order": 0
            },
            "order": 0
        }
    ]
