基于node.js及express实现中间件，实现post、get

首先，当然是有必要的环境，安装node，这个我就不多说了。

依赖模块：

"express": "^4.13.4",

"request": "^2.72.0",

"body-parser": "^1.13.3",

页面

 $.ajax({type: "post",url: "/api",contentType: "application/json",    //data: {"UserName":"struggle","password":123456},  //普通数据data: JSON.stringify({"formdata":{"UserName":"struggle","password":123456}}),       //这里为了应付需要传复杂的json数据success:function(msg){console.log(msg);}});

服务端：

var express = require('express');
var app = express();
var bodyParser = require('body-parser');// 解析json，need it...
app.use(bodyParser.urlencoded({extended: false}));
app.use(bodyParser.json());                    app.post('/api', function(req, res,next){console.log('post-test');console.log(req.body.formdata);  var request = require('request');request.post('http://192.168.1.220:8094/User/Login',{form:req.body.formdata},function(err, response, body){res.send(body);   //返回的数据
        });
});app.use(express.static(path.join(__dirname, '/')))app.listen(8080);    
console.log('Listening on port 8080');
