vue引入axios同源跨域问题

前言：

跨域方案有很多种，既然我们用到了vue，那么就使用vue提供的跨域方案。

解决方案：

1.修改httprequestutil.js

 import axios from 'axios'
 export var baseurl = '/api'
 /**
 * get请求
 */
 export function get(url, callback){
  console.log('测试get请求')
  axios.get(baseurl+url)
  .then(function (response) {
   console.log(response)
   callback(response.data,true)
  })
  .catch(function (error) {
   console.log(error)
   callback(null,false)
  })
 }
 export default {
  get
 }

2.修改index.js

'use strict'
 // template version: 1.3.1
 // see http://vuejs-templates.github.io/webpack for documentation. 
 const path = require('path') 
 module.exports = {
 dev: {
  // paths
  assetssubdirectory: 'static',
  assetspublicpath: '/',
  proxytable: {
  '/api': {
   target: 'http://127.0.0.1:8088',//设置你调用的接口域名和端口号 别忘了加http
   changeorigin: true,
   pathrewrite: {
   '^/api': 'http://127.0.0.1:8088'//这里理解成用‘/api'代替target里面的地址，后面组件中我们掉接口时直接用api代替 比如我要调用'http://40.00.100.100:3002/user/add'，直接写‘/api/user/add'即可
   }
  }
  },
  // various dev server settings
  host: 'localhost', // can be overwritten by process.env.host
  port: 8090, // can be overwritten by process.env.port, if port is in use, a free one will be determined
  autoopenbrowser: false,
  erroroverlay: true,
  notifyonerrors: true,
  poll: false, // https://webpack.js.org/configuration/dev-server/#devserver-watchoptions-
  /**
  * source maps
  */
  // https://webpack.js.org/configuration/devtool/#development
  devtool: 'cheap-module-eval-source-map',
  // if you have problems debugging vue-files in devtools,
  // set this to false - it *may* help
  // https://vue-loader.vuejs.org/en/options.html#cachebusting
  cachebusting: true,
  csssourcemap: true
 },
 build: {
  // template for index.html
  index: path.resolve(__dirname, '../dist/index.html'),
  // paths
  assetsroot: path.resolve(__dirname, '../dist'),
  assetssubdirectory: 'static',
  assetspublicpath: '/',
  /**
  * source maps
  */
  productionsourcemap: true,
  // https://webpack.js.org/configuration/devtool/#production
  devtool: '#source-map',
  // gzip off by default as many popular static hosts such as
  // surge or netlify already gzip all static assets for you.
  // before setting to `true`, make sure to:
  // npm install --save-dev compression-webpack-plugin
  productiongzip: false,
  productiongzipextensions: ['js', 'css'],
  // run the build command with an extra argument to
  // view the bundle analyzer report after build finishes:
  // `npm run build --report`
  // set to `true` or `false` to always turn it on or of
  bundleanalyzerreport: process.env.npm_config_report
 }
 }

proxytable: {
'/api' : {
target: 'http://127.0.0.1:8088' , //设置你调用的接口域名和端口号 别忘了加http
changeorigin: true ,
pathrewrite: {
'^/api' : 'http://127.0.0.1:8088' //这里理解成用‘/api'代替target里面的地址，后面组件中我们掉接口时直接用api代替 比如我要调用'http://40.00.100.100:3002/user/add'，直接写‘/api/user/add'即可
}
}
},
