详解VueJs前后端分离跨域问题

使用vue-cli搭建的vue项目

可以使用在项目内设置代理(proxyTable)的方式来解决跨域问题

设置配置项的目录在config下的index.js,主要通过配置proxyTable项,设置代理指向你的后台地址

dev: { env: require('./dev.env'), port: 8085, autoOpenBrowser: true, assetsSubDirectory: 'static', assetsPublicPath: 'https://www.jb51.net/', proxyTable: { '/agent': { target: 'http://127.0.0.1:7105/', changeOrigin: true, pathRewrite: { '^/agent': '' } } }, // 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 }

前端使用vue-resource来发起请求时

//在main.js中设置公用的地址 Vue.prototype.rootUrl = '/agent/'; //在具体page中发起请求的方式 that.$http.post(this.rootUrl + 'login', parms).then(function (response) { // 响应成功回调 console.log(response); }, function (response) { // 响应错误回调 });

其他方式搭建的前端项目,通过使用nginx启动前端服务同时配置代理

下列是我的nginx配置文件,不管是通过什么方式搭建的前端项目,构建成功后都会输出一个dist文件,我们只需要将nginx服务目录指向你的dist文件下你项目的入口文件即可

我的文件目录是 root D:\openplatform\portal\webapp\dist; 更改此条配置到你的目录 我入口文件名称是index.html 使用的是vue-cli打包的项目,参考vue-cli npm run build的dist目录,指向那个目录下
