【前端知识】Node——http模块url模块的常用操作

一、创建简易Server

const http = require('http');
const URL = require('url');const HTTP_PORT = 8088;const server = http.createServer((req, res) => {// req：request请求对象，包含请求相关的信息；// res：response响应对象，包含我们要发送给客户端的信息；const { headers, method, url } = req;console.log( headers, method, url);
});server.listen(HTTP_PORT, () => {console.log(`🚀 Outman 服务器已启动，端口：${HTTP_PORT}`);
})

二、url相关处理

const http = require('http');
const URL = require('url');const HTTP_PORT = 8088;const server = http.createServer((req, res) => {// req：request请求对象，包含请求相关的信息；// res：response响应对象，包含我们要发送给客户端的信息；const { headers, method, url } = req;console.log( headers, method, url);// url处理if(url === '/login'){res.end('hello outman');}else if(url === '/products'){res.end('products list');}else{res.end('error request');}// url带参解析(GET)const parseInfo = URL.parse(req.url);console.log(parseInfo);const { pathname, query } = URL.parse(req.url);const queryObj = URL.parse(query);console.log(pathname, queryObj);
});server.listen(HTTP_PORT, () => {console.log(`🚀 Outman 服务器已启动，端口：${HTTP_PORT}`);
})

三、请求配置与监听

const http = require('http');
const URL = require('url');const HTTP_PORT = 8088;const server = http.createServer((req, res) => {// req：request请求对象，包含请求相关的信息；// res：response响应对象，包含我们要发送给客户端的信息；const { headers, method, url } = req;console.log( headers, method, url);// req 配置 & 监听req.setEncoding('utf-8');// 监听获取body中的参数(POST)req.on('data', (data) => {console.log('data', data);const { username, password } = JSON.parse(data);console.log(username, password);});req.on('end', () => {console.log('传输结束');});res.end('outman msg')
});server.listen(HTTP_PORT, () => {console.log(`🚀 Outman 服务器已启动，端口：${HTTP_PORT}`);
})

四、常用HTTP CODE
