1.gulp browserSync proxy

var url = require('url');
var proxy = require('proxy-middlewre');

var proxyOptions = url.parse('http://192.168.85.201:3000');
    proxyOptions.route = '/api';
    // requests to `http://192.168.85.201:8000/api/login` are proxied to `http://192.168.85.201:3000/login`

    browserSync.init({
        server: {
            baseDir: "./",
            directory: true,
            middleware: [proxy(proxyOptions)]
        }
    });

2.webpack proxy

var webpack = require('webpack');
var WebpackDevServer = require('webpack-dev-server');
var config = require('./build/webpack.config');

// 相当于经由过程当地node效劳代办要求到了http://cnodejs.org/api
var proxy = {
    '/api/*': {
            target: 'https://cnodejs.org',
            secure: false
        }
}

//启动效劳
var server = new WebpackDevServer(webpack(config), {
    publicPath: config.output.publicPath,
    proxy: proxy,
    stats: {
        colors: require('supports-color')
    },
});

//将其他路由，悉数返回index.html
server.app.get('*', function (req, res) {
    res.sendFile(__dirname + '/index.html')
});

server.listen(9999);
