1、自己写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];

console.log(url,get);

res.write('aaa');

res.end();

}

}else{

var url = req.url;

}

console.log(url,get);

res.write('aaa');

res.end();
}).listen(8080);2、引入querystring模块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);
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);
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代码提交表单的HTML代码

个人练习如下：个人练习如下：
const http = require("http");
const queryString = require("querystring");
const urlNode = require('url');

http.createServer((req,res)=>{

console.log(req.url);
// /aaa?user=123&pass=456

var get = {};

var url = '';

if(req.url.indexOf('?') != -1){


//方法一：切割字符串

// var _arr = req.url.split('?'); //['aaa','user=123&pass=456']

// url = _arr[0]; //'aaa'

// var _arr2 = _arr[1].split('&'); //['user=123','pass=456']

// _arr2.map((v,k,arr)=>{

//
var key = v.split('=')[0];

//
var value = v.split('=')[1];

//
get[key] = value;

// })


//方法二：正则表达式

// var query = req.url.substr(req.url.indexOf('?')+1);

// var regAll = new RegExp("([^?&=]+)=([^?&=]*)", "gi");

// var regSingle = new RegExp("([^?&=]+)=([^?&=]*)", "i");

// var arrAll = query.match(regAll);
//["user=123", "pass=456"]

// arrAll.map(function(v,k,arr){

//
var resultArr = v.match(regSingle);

//
get[resultArr[1]] = resultArr[2];

// })

//方法三：引入querystring模块

// const arr = req.url.split('?');

// url = arr[0];

// get = queryString.parse(arr[1]);

//方法四：

// const obj = urlNode.parse(req.url,true);

// url = obj.pathname;

// get = obj.query;


}else{

url = req.url;

}

console.log(url,get);

res.write('123456')

res.end('12')
}).listen(8000)
const http = require("http");

const urlNode = require('url');

http.createServer((req,res)=>{

console.log(req.url);
// /aaa?user=123&pass=456

var get = {};

var url = '';

if(req.url.indexOf('?') != -1){

}else{

url = req.url;

}

console.log(url,get);

res.write('123456')

res.end('12')
}).listen(8000)以上都 是原生node实现：以上都 是原生node实现：下面的是express中 req.query 就可以方便的取到 { id 123456}
app.get('/article',(req,res)=>{

console.log(req.query)


})
app.get('/article',(req,res)=>{

console.log(req.query)


})以上就是本文的全部内容，希望对大家的学习有所帮助。
