带有旁路代理的Webpack-dev服务器

如何实现代理' (与Web地址开发服务器类似grunt-connect-proxy)选项?

我正在使用webpackwebpack-dev-server与Grunt。 Gruntfile.js(代码下面)中的任务能够在端口8080上启动服务器。我想为所有后端数据请求添加代理设置(上下文URL / ajax / *)。

       "webpack-dev-server": {
        options: {
            webpack: webpackConfig,
            publicPath: "/src/assets"
        },
        start: {
            keepAlive: true,
            watch: true              
        }
    }

在webpack配置中,您可以像这样使用devServer.proxy:

proxy: {
    '/ajax/*': 'http://your.backend/'
}

我最终使用了' grunt-contrib-connect'和' grunt-connect-proxy'使用' webpack-dev-middleware'。所以,我可以使用代理中间件来处理我的所有数据请求和webpack中间件来处理静态捆绑文件请求。

    var proxySnippet = require('grunt-connect-proxy/lib/utils').proxyRequest;
    var mountFolder = function (connect, dir) {
       return connect.static(require('path').resolve(dir));
    };

    var prepareDevWebpackMiddleware = function() {

        webpackConfig.devtool = "eval-source-map";
        var compiler = webpack(require("./webpack.config.js"));

        return webpackDevMiddleware(compiler, {
            publicPath : "/assets"           
       });
    };

        connect: {
            options: {
                port: 8080,
                hostname: 'localhost',
                livereload : true
            },
            proxies: [{
                context: '/api',
                host: 'localhost',
                port: 8000
            }],
            livereload: {
                options: {
                    middleware: function (connect) {
                        return [
                            prepareDevWebpackMiddleware(),
                            proxySnippet,
                            mountFolder(connect, 'src')
                        ];
                    }
                }
            }

自v1.15以来,Webpack dev服务器代理api已经更改

https://github.com/webpack/webpack-dev-server/issues/562

glob *应该**代理所有请求

  devServer: {
    proxy: {
      '**': 'http://local.ui.steelhouse.com/'
    },
  }

webpack-dev-server不知道如何处理您的内容,因此它有一个配置,可以代理您对特定服务器处理内容的所有请求。

例如:

你应该运行' grunt内容'启动内容服务器 然后运行' grunt serve'开始发展



'use strict';

var webpackDistConfig = require('./webpack.dist.config.js'),
    webpackDevConfig = require('./webpack.config.js');

var mountFolder = function (connect, dir) {
   return connect.static(require('path').resolve(dir));
};

module.exports = function (grunt) {
  // Let *load-grunt-tasks* require everything
  require('load-grunt-tasks')(grunt);

  // Read configuration from package.json
  var pkgConfig = grunt.file.readJSON('package.json');

  grunt.initConfig({
    pkg: pkgConfig,

    webpack: {
      options: webpackDistConfig,

      dist: {
        cache: false
      }
    },
