express框架是nodejs的一个优秀的web框架，继承了许多简单易用的方法
1、创建web服务器并接受get请求
首先要安装express
npm install express --save
const express = require('express');
const app = express();
app.get('/getName', function(req, resp){
resp.send('孙悟空');
});
app.listen('8000', function(){
console.log('server is running at port 8000...');
});2、post请求并获请求取参数
const express = require('express');
const bodyParser = require('body-parser');
const app = express();
const urlencodedParser = bodyParser.urlencoded({ extended: false })
app.get('/getName', function(req, resp){
resp.send('孙悟空');
});
app.post('/test_post', urlencodedParser, function (req, res) {
var response = {
"first_name":req.body.first_name,
"last_name":req.body.last_name
};
console.log(response);
res.end(JSON.stringify(response));
})
app.listen('8000', function(){
console.log('server is running at port 8000...');
