vue axios使用之跨域解决_vue中axios跨域-优快云博客

本文介绍了在Vue项目中使用Axios进行跨域请求的解决方案。首先在/config/index.js中调整配置，然后在api.js文件中修改接口地址。若遇到404错误，可能需更改端口并重启服务。同时，可以通过then(res.headers)获取响应头部信息。

1.首先修改项目/config/index.js中的配置贴出我的js，备注说明//--------

var path = require('path')

module.exports = {
  build: {
    env: require('./prod.env'),
    index: path.resolve(__dirname, '../dist/index.html'),
    assetsRoot: path.resolve(__dirname, '../dist'),
    assetsSubDirectory: 'static',
    assetsPublicPath: '/vue-admin/',
    productionSourceMap: true,
    // 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 off
    bundleAnalyzerReport: process.env.npm_config_report
  },
  dev: {
    env: require('./dev.env'),
    port: 8086,                       //------启动端口
    autoOpenBrowser: true,
    assetsSubDirectory: 'static',
    assetsPublicPath: '/',
    proxyTable: {                    //------下面为解决跨域添加
      '/api':{                       //------为请求的接口添加特殊标识
        target: "http://10.164.25.210:5000",   //------跨域地址
        changeOrigin:true,           //------跨域时必须参数
        pathRewrite:{                //------匹配api之前的内容替换为 /v3
            '^/api':'/v3'
        }
      },
      '/apiBMC':{                   //------多api请求，与上面示意相同
        target: "http://10.164.25.210:6385",
        changeOrigin:true,
        pathRewrite:{
            '^/apiBMC':'/v1'
        }
      }
    },
    // CSS Sourcemaps off by default because relative paths are "buggy"
    // with this option, according to the CSS-Loader README
    // (https://github.com/webpack/css-loader#sourcemaps)
    // In our experience, they generally work as expected,
    // just be aware of this issue when enabling this option.
    cssSourceMap: false
  }
}

2.调用axios的位置我的为api.js,修改接口地址

import Vue from 'vue'
import axios from 'axios';
import qs from 'qs';

Vue.prototype.$axios = axios
//axios.defaults.baseURL = '/api'
axios.defaults.headers.post['Content-Type'] = 'application/json';

let base = '';
let token = sessionStorage.getItem('X-Subject-Token');    

export const requestLogin = params => { 
	return axios.post('api/auth/tokens', params).then(res => res); //qs.stringify(
};   //------api/auth/tokens其中api为替换内容，整体访问接口http://10.164.25.210:5000/v3/auth/tokens

3.如果配置后访问出现404，可能是缓存问题，换个端口重启，修改port：8086

4.获取访问几口响应的头部，then(res.headers)
