啟動文件 /app.js：

var express = require('express'); var bodyParser = require('body-parser'); var proxy = require('http-proxy-middleware'); var path = require('path');var index = require('./routes/index'); var data = require('./routes/data');var app = express();/* 設置靜態目錄 */ app.use(express.static('src'));/* 啟用反向代理 */ var options = {target: 'http://localhost:8080/h5', // 目標主機changeOrigin: true,//secure: false,// ws: true,// pathRewrite: {// '^/api' : '/h5/api'// } }; var apiProxy = proxy(options); // 開啟代理功能，并加載配置 app.use('/api', apiProxy); // 對地址為’/‘的請求全部轉發// Node Express API 路由配置 app.use('/', index); app.use('/data', data);// // catch 404 and forward to error handler // app.use(function(req, res, next) { // var err = new Error('Not Found'); // err.status = 404; // next(err); // });// // error handler // app.use(function(err, req, res, next) { // // set locals, only providing error in development // res.locals.message = err.message; // res.locals.error = req.app.get('env') === 'development' ? err : {}; // // // render the error page // res.status(err.status || 500); // res.render('error'); // });/* json 輸出支持, 啟動服務 */ app.use(bodyParser.json()); app.listen(7788);var url = "http://localhost:7788"; console.log('listen: ' + url);/* 啟動瀏覽器訪問站點 */ var child_process = require("child_process"); var cmd = 'start ' + url;if(process.platform == 'linux'){cmd = 'xdg-open '; }else if(process.platform == 'darwin'){cmd = 'open '; } // else{ // process.platform == 'win32' // cmd = 'start "%ProgramFiles%\Internet Explorer\iexplore.exe"'; // }child_process.exec(cmd + ' "'+url + '"'); //child_process.exec(cmd + url);

路由配置 /routes/index.js

var express = require('express'); var router = express.Router();/* GET home page data. */ router.get('/', function(req, res, next) {res.send({ title: '首頁' }); });router.get('/login', function(req, res, next) {res.send({ title: '登錄' }); });module.exports = router;

路由配置 /routes/data.js
