angular 中配置跨域

1. 新建一个 proxy.conf.json

{

    "/search": {

        "target": "https://wenku.baidu.com/search",

        "secure": false,

        "changeOrigin": true

    },

    "/getnotice": {

        "target": "https://wenku.baidu.com/message/getnotice",

        "secure": false,

        "changeOrigin": true

    },

    "/api": {

        "target": "https://wenku.baidu.com",

        "secure": false,

        "changeOrigin": true

    }

}

2. 在 package.json 中

  "name": "angular-demo",

  "version": "0.0.0",

  "scripts": {
