## Spring Cloud GateWay构建Route的应用 ##

1.使用Java API方式构建路由  
1）添加依赖配置

2）配置路由规则

通过RouteLocatorBuilder接口来构建路由规则，此处使用的是指定的Path来构建路由

3）验证路由

启动项目，浏览器访问http://localhost:8080/shenzhen/a，会进入https://www.jd.com/

之后可以在项目控制台的debug info中看到匹配的路由是forward

2.使用配置文件方式构建路由  
1）添加依赖配置

2）使用指定Path匹配指定路由

在application.properties中配置端口、route的id、uri、predicates

启动项目后，浏览器访问http://localhost:8220/foundation，会进入https://www.apache.org/foundation/

![在这里插入图片描述][20200813132606951.gif_pic_center]

项目的debug info中显示匹配的路由id是Path\_Route

3）使用After路由规则匹配指定路由

在application.properties中配置端口、route的id、uri、predicates

启动项目后，浏览器访问http://localhost:8220/index.html，会进入https://www.apache.org/index.html/

![在这里插入图片描述][20200813132646415.gif_pic_center]

项目的debug info中显示匹配的路由id是After\_Route

4）使用指定Cookie匹配指定路由

在application.properties中配置端口、route的id、uri、predicates

![在这里插入图片描述][2020081313212181.png_pic_center]

使用curl访问 http://localhost:8220 会接收mysql服务器返回资源文件  
![在这里插入图片描述][20200813132127512.png_pic_center]

curl http://localhost:8220 --cookie “name=wxl”

5）使用综合路由规则匹配指定路由

可以在配置文件中对11种路由规则综合配置

启动项目后，浏览器访问http://localhost:8220/index.html，会进入https://www.oracle.com/index.html/  
![在这里插入图片描述][20200813132748637.gif_pic_center]

项目的debug info中显示匹配的路由id是Weight\_Route2

## \* 某些路由匹配规则之间会存在相互冲突，请按实际效果配置使用顺序 ##
