4.vue引入axios同源跨域

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

}

}
