【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}`);
})
