Install the vue-resource plug-in

Cnpm install vue-resource-save

Check the version of the plug-in in package.json in the root directory

Import files under rourer-index.js

Import Resource from 'vue-resource'Vue.use (Resource)

After introducing vue-resource, you can use http based on global Vue objects, or you can use http reference links based on a Vue instance

Install the axios plug-in

Cnpm install-save axios

Introduced in the background service file (server.js)

Var axios = require ('axios')

Create a new public Js file to store httpserver

Import axios from 'axios' / / introduces the axios plug-in export function getHttp (url, callFun) {/ / get request method axios.get (url) .then (callFun) .catch (function (err) {console.log (err)})}

III. Proxy agent

Find the proxyTable setting agent under the config-index.js file

For example, my vue project link is localhost:8080 background data address is localhost:8081/api/seller (port is not the same)

ProxyTable: {'/ api': {target: 'http://localhost:8081', changeOrigin: true, pathRewrite: {' ^ / api':'/ api' / / pathRewrite method overrides url, so that the configured url overrides url with the method http://localhost:8081/api/seller / /'^ / api':'/'/ / pathRewrite The configured url is http://localhost:8081/seller}.

4. Data call

Write the following code in the vue page where you want to call the data

Js part

Import {getHttp} from'.. / static/js/httpserver.js'export default {data () {return {seller: {}, methods: {shangjia: function () {let url ='/ api/seller' getHttp (url, function (res) {res = res.data console.log (res)})}
