Post请求

var http=require(‘http‘);
var qs=require(‘querystring‘);
 
var post_data={a:123,time:new Date().getTime()};//这是需要提交的数据
var content=qs.stringify(post_data);
 
var options = {
  host: ‘127.0.0.1‘,
  port: 8080,
  path: ‘/admin‘,
  method: ‘POST‘,
  headers:{
  ‘Content-Type‘:‘application/x-www-form-urlencoded‘,//post请求需要设置的type值
  ‘Content-Length‘:content.length
  }
};
console.log("post options:\n",options);
console.log("content:",content);
console.log("\n");
 var a=‘‘
var req = http.request(options, function(res) {
  console.log("statusCode: ", res.statusCode);
  console.log("headers: ", res.headers);
  var _data=‘‘;
  res.on(‘data‘, function(chunk){
     _data += chunk;
     a=chunk;
  });
  res.on(‘end‘, function(){
     console.log("\n--->>\nresult:",_data)
   });
});
 
req.write(content);
req.end();

http.createServer(function (request, response) {  
  
    // 发送 HTTP 头部   
    // HTTP 状态值: 200 : OK  
    // 内容类型: text/plain  
    response.writeHead(200, {‘Content-Type‘: ‘text/plain‘});  
  	response.write(a)
    // 发送响应数据 "Hello World"  
    response.end(‘Hello World\n‘);  
}).listen(8888);  

　　在服务中解析Post请求参数

var express=require(‘express‘);
var app=express();
var bodyParser = require("body-parser");
app.use(bodyParser.urlencoded({ extended: false }));
app.post(‘/admin‘,(req,res)=>{
	console.log(req)
	var data={
		code:200,
		msg:‘success‘
	}
	res.json(data);
})

app.listen(8080,()=>{

	console.log(8080)
})
