( 基于 Express 4.x )

启动文件 /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();/* 设置静态目录 */
app.use(express.static('src'));/* 启用反向代理 */
var options = {target: 'http://localhost:8080/h5', // 目标主机changeOrigin: true,//secure: false,// ws: true,// pathRewrite: {//     '^/api' : '/h5/api'// }
};
var apiProxy = proxy(options);  // 开启代理功能，并加载配置
app.use('/api', apiProxy);      // 对地址为’/‘的请求全部转发// 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 输出支持, 启动服务 */
app.use(bodyParser.json());
app.listen(7788);var url = "http://localhost:7788";
console.log('listen: ' + url);/* 启动浏览器访问站点 */
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: '首页' });
});router.get('/login', function(req, res, next) {res.send({ title: '登录' });
});module.exports = router;

路由配置 /routes/data.js

var express = require('express');
var router = express.Router();
var fs = require('fs');
var PATH = './public/data/';//读取数据模块，供客户端调用
//查询接口，token校验
//公共接口，无需校验
//data/read?type=it
//data/read?type=it.json
router.get('/read', function(req, res, next) {var type = req.param('type') || "";fs.readFile(PATH + type + '.json', function (err, data){if(err){return res.send({success: false,message: '读取文件异常'});}var COUNT = 50;// TODO: try{}catch(){}var obj =[];try{obj = JSON.parse(data.toString());}catch(e){obj = [];}if(obj.length > COUNT){obj = obj.slice(0, COUNT);}return res.send({success: true,data:obj});});
});// 数据存储模块——后台开发使用
router.post('/write',function(req, res, next){if(!req.cookies.user){return res.render('login',{});}// 文件名var type = req.param('type') || "";// 关键字段var url = req.param('url') || '';var title = req.param('title') || '';var img = req.param('img') || '';if(!type || !url || !title || !img){return res.send({success: false,message:'提交的字段不全'});}//1)读取文件var filePath = PATH + type + '.json';fs.readFile(filePath, function(err, data){if(err){return res.send({success: false,message: '读取数据失败'});}var arr = JSON.parse(data.toString());//代表每一条记录var obj = {img: img,url: url,title: title,id: guidGenerate(),time: new Date()};arr.splice(0, 0, obj);//2)写入文件var newData = JSON.stringify(arr);fs.writeFile(filePath, newData, function(err){if(err){return res.send({status:0,info: '写入文件失败'});}return res.send({success: true,message: obj});});});
});//阅读模块写入接口 后台开发使用
router.post('/write_config', function(req, res, next){if(!req.cookies.user){return res.render('login',{});}//TODO:后期进行提交数据的验证//防xss攻击 xss// npm install xss// require('xss')// var str = xss(name);var data = req.body.data;//TODO ： try catchvar obj = JSON.parse(data);var newData = JSON.stringify(obj);// 写入fs.writeFile(PATH + 'config.json',newData, function(err, data){if(err){return res.send({success: false,message: '写入数据失败'});}return res.send({success: true,message:'数据写入成功',data:newData})})
});//登录接口
router.post('/login', function(req, res, next){//用户名、密码、验证码var username = req.body.username;var password = req.body.password;//TODO ：对用户名、密码进行校验//xss处理、判空//密码加密 md5(md5(password + '随机字符串'))//密码需要加密－> 可以写入JSON文件if(username === 'admin' && password === '123456'){res.cookie('user',username);return res.send({success: true});}return res.send({success: false,message: '登录失败'});
});// guid
function guidGenerate() {return 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g, function(c) {var r = Math.random() * 16 | 0,v = c == 'x' ? r : (r & 0x3 | 0x8);return v.toString(16);}).toUpperCase();
