本篇文章主要介紹了詳解VueJs前后端分離跨域問(wèn)題，詳細(xì)介紹了在項(xiàng)目?jī)?nèi)設(shè)置代理（proxyTable）的方式來(lái)解決跨域問(wèn)題，有興趣的可以了解一下

使用vue-cli搭建的vue項(xiàng)目

可以使用在項(xiàng)目?jī)?nèi)設(shè)置代理（proxyTable）的方式來(lái)解決跨域問(wèn)題

設(shè)置配置項(xiàng)的目錄在config下的index.js，主要通過(guò)配置proxyTable項(xiàng)，設(shè)置代理指向你的后臺(tái)地址

dev: {
  env: require('./dev.env'),
  port: 8085,
  autoOpenBrowser: true,
  assetsSubDirectory: 'static',
  assetsPublicPath: '/',
  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來(lái)發(fā)起請(qǐng)求時(shí)

//在main.js中設(shè)置公用的地址
Vue.prototype.rootUrl = '/agent/';

//在具體page中發(fā)起請(qǐng)求的方式
that.$http.post(this.rootUrl + 'login', parms).then(function (response) {
     // 響應(yīng)成功回調(diào)
     console.log(response);
    }, function (response) {
     // 響應(yīng)錯(cuò)誤回調(diào)
    });

其他方式搭建的前端項(xiàng)目，通過(guò)使用nginx啟動(dòng)前端服務(wù)同時(shí)配置代理

下列是我的nginx配置文件，不管是通過(guò)什么方式搭建的前端項(xiàng)目，構(gòu)建成功后都會(huì)輸出一個(gè)dist文件，我們只需要將nginx服務(wù)目錄指向你的dist文件下你項(xiàng)目的入口文件即可

我的文件目錄是 root D:\openplatform\portal\webapp\dist; 更改此條配置到你的目錄我入口文件名稱是index.html 使用的是vue-cli打包的項(xiàng)目，參考vue-cli npm run build的dist目錄，指向那個(gè)目錄下

#error_log logs/error.log notice;

  log_format main '[$time_iso8601] [$remote_addr] [$request] [$http_user_agent] [$cookie_customerID_cookie_flag] [$args]';

       index index.html;
      }
  location @router {

    }
  location ^~/agent/ {

      proxy_send_timeout 600s;
    }
  }
