express路由中间件

记录一下express中间件的使用，防止以后用的时候找不到

var express			= require(‘express’);
var bodyParser		= require(‘body-parser’);
var multer			= require(‘multer’);
var app				= express();

//for parsing application/json
app.use(bodyParser.json());

//for parsing application/x-www-form-urlencoded
app.use(bodyParser.urlencoded({ extended: true }));

//for parsing multipart/form-data //需要用npm install multer@0.1.8
app.use(multer());
