一，对于使用creat-react-app构建的项目，可以直接在package.json下配置，具体如下

"proxy": "http://api.xxxx.com"

或者如果创建多个域，该如何设置proxy,能满足可以调用不同域下的API的需求？代码如下

//package.json中加入"proxy": {  "/api/RoomApi": {    "target": "http://open.douyucdn.cn",    "changeOrigin":true  },  "/api/v1":{    "target":"http://capi.douyucdn.cn",    "changeOrigin":true  }}

二，对于antd-pro的项目，需要在package.json的同等目录下添加.roadhogrc文件，具体代码:

{  "entry": "src/index.js",  "extraBabelPlugins": [    "transform-runtime",    "transform-decorators-legacy",    "transform-class-properties",    ["import", { "libraryName": "antd", "libraryDirectory": "es", "style": true }]  ],  "env": {    "development": {      "extraBabelPlugins": [        "dva-hmr"      ]    }  },  "externals": {    "g2": "G2",    "g-cloud": "Cloud",    "g2-plugin-slider": "G2.Plugin.slider"  },  "ignoreMomentLocale": true,  "theme": "./src/theme.js",  "proxy": {    "/api": {      "target": "http://api.xxxx.com/",      "changeOrigin": true    }  }}
