vue引入axios同源跨域
阿新 • • 發佈:2018-11-08
前言:
跨域方案有很多種,既然我們用到了Vue,那麼就使用vue提供的跨域方案。
解決方案:
1.修改HttpRequestUtil.js
1 import axios from 'axios' 2 3 export var baseurl = '/api' 4 /** 5 * Get請求 6 */ 7 export function get(url, callback){ 8 console.log('測試get請求') 9 axios.get(baseurl+url) 10 .then(function (response) { 11 console.log(response) 12 callback(response.data,true) 13 }) 14 .catch(function (error) { 15 console.log(error) 16 callback(null,false) 17 }) 18 } 19 20 21 export default { 22 get 23 }
2.修改index.js
1 'use strict' 2 // Template version: 1.3.1 3 // see http://vuejs-templates.github.io/webpack for documentation. 4 5 const path = require('path') 6 7 module.exports = { 8 dev: { 9 10 // Paths 11 assetsSubDirectory: 'static', 12 assetsPublicPath: '/', 13 proxyTable: { 14 '/api': { 15 target: 'http://127.0.0.1:8088',//設定你呼叫的介面域名和埠號 別忘了加http 16 changeOrigin: true, 17 pathRewrite: { 18 '^/api': 'http://127.0.0.1:8088'//這裡理解成用‘/api’代替target裡面的地址,後面元件中我們掉介面時直接用api代替 比如我要呼叫'http://40.00.100.100:3002/user/add',直接寫‘/api/user/add’即可 19 } 20 } 21 }, 22 23 // Various Dev Server settings 24 host: 'localhost', // can be overwritten by process.env.HOST 25 port: 8090, // can be overwritten by process.env.PORT, if port is in use, a free one will be determined 26 autoOpenBrowser: false, 27 errorOverlay: true, 28 notifyOnErrors: true, 29 poll: false, // https://webpack.js.org/configuration/dev-server/#devserver-watchoptions- 30 31 32 /** 33 * Source Maps 34 */ 35 36 // https://webpack.js.org/configuration/devtool/#development 37 devtool: 'cheap-module-eval-source-map', 38 39 // If you have problems debugging vue-files in devtools, 40 // set this to false - it *may* help 41 // https://vue-loader.vuejs.org/en/options.html#cachebusting 42 cacheBusting: true, 43 44 cssSourceMap: true 45 }, 46 47 build: { 48 // Template for index.html 49 index: path.resolve(__dirname, '../dist/index.html'), 50 51 // Paths 52 assetsRoot: path.resolve(__dirname, '../dist'), 53 assetsSubDirectory: 'static', 54 assetsPublicPath: '/', 55 56 /** 57 * Source Maps 58 */ 59 60 productionSourceMap: true, 61 // https://webpack.js.org/configuration/devtool/#production 62 devtool: '#source-map', 63 64 // Gzip off by default as many popular static hosts such as 65 // Surge or Netlify already gzip all static assets for you. 66 // Before setting to `true`, make sure to: 67 // npm install --save-dev compression-webpack-plugin 68 productionGzip: false, 69 productionGzipExtensions: ['js', 'css'], 70 71 // Run the build command with an extra argument to 72 // View the bundle analyzer report after build finishes: 73 // `npm run build --report` 74 // Set to `true` or `false` to always turn it on or of 75 bundleAnalyzerReport: process.env.npm_config_report 76 } 77 }
proxyTable: {
'/api' : {
target: 'http://127.0.0.1:8088' , //設定你呼叫的介面域名和埠號 別忘了加http
changeOrigin: true ,
pathRewrite: {
'^/api' : 'http://127.0.0.1:8088' //這裡理解成用‘/api’代替target裡面的地址,後面元件中我們掉介面時直接用api代替 比如我要呼叫'http://40.00.100.100:3002/user/add',直接寫‘/api/user/add’即可
}
}
