1、自己写

const http = require('http');

http.createServer(function(req,res){
    var get = {};
    if(req.url.indexOf('?')!=-1){
        var arr = req.url.split('?');
        var url = arr[0];
        var arr2 = arr[1].split('&');
        for(var i=0;i<arr2.length;i++){
            var arr3 = arr2[i].split('=');
            get[arr3[0]]=arr3[1];
        }
    }else{
        var url = req.url;
    }
    console.log(url,get);
    res.write('aaa');
    res.end();
}).listen(8080);

2、引入querystring模块

const http = require('http');
const querystring = require('querystring');
http.createServer(function(req,res){
    var get = {};
    if(req.url.indexOf('?')!=-1){
        var arr = req.url.split('?');
        var url = arr[0];
        get = querystring.parse(arr[1]);
    }else{
        var url = req.url;
    }
    console.log(url,get);
    res.write('aaa');
    res.end();
}).listen(8080);

3、引入url模块

const http = require('http');
const urlli = require('url');

http.createServer(function(req,res){
    var obj = urlli.parse(req.url,true); //true解析，如果没有true，默认不解析
    var url = obj.pathname;
    var get = obj.query;
    console.log(url,get);
    res.write('aaa');
    res.end();
}).listen(8080);

提交表单的HTML代码

<!DOCTYPE html>
<html lang="en">
<head>
	<meta charset="UTF-8">
	<title>Document</title>
</head>
<body>
	<form action="http://localhost:8080/aaa" method="get">
		用户：<input type="text" name="user" value=''><br>
		密码：<input type="password" name="pass" value=''><br>
		<input type="submit" value="提交">
	</form>
</body>
</html>
