React配置多个代理

1.在src(开发环境当中)下新建一个 setupProxy.js文件
2.下载 http-proxy-middleware 模块
```
cnpm install http-proxy-middleware -S
```

引入

const { createProxyMiddleware }` = require("`http-proxy-middleware`")

4.使用

module.exports = function(app) {
  app.use("/api",createProxyMiddleware({
      target:'http://127.0.0.1',
      changeOrigin:true,
      pathRewrite:{
          "^/api":""
      }
  }))
   app.use("/user",createProxyMiddleware({
      target:'http://127.0.0.1:8080',
      changeOrigin:true,
      pathRewrite:{
          "^/user":""
      }
  }))
}
