Express采坑系列之POST请求

// 允许所有的请求形式 
app.use(function(req, res, next) { 
  res.header("Access-Control-Allow-Origin", "*"); 
  res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
  next();
});

// 引入json解析中间件
var bodyParser = require(‘body-parser‘);

// 添加json解析
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended: false}));

var express = require(‘express‘);
var router = express.Router();


router.post(‘/‘, function(req, res, next) {

  // 获取参数
  var query = req.body;
  console.log("post请求：参数", query);

  res.send(‘hello , world‘);
});
