前言
我是歌谣 今天给大家带来的是关于node中http模块的一个讲解
案例1
const http=require("http")
//创建服务器
http.createServer(()=>{
}).listen(3002,()=>{
console.log("geyao.....")
})
运行结果
案例2
const http=require("http")
//创建服务器
http.createServer((req,res)=>{
res.write("hello geyao1")
res.end()
}).listen(3002,()=>{
console.log("geyao.....")
})
运行结果
案例3
const http=require("http")
//创建服务器
http.createServer((req,res)=>{
res.write(`<html>
<p>hello geyao</p>
</html>`)
res.end()
}).listen(3002,()=>{
console.log("geyao.....")
})
运行结果
案例4
const http=require("http")
//创建服务器
http.createServer((req,res)=>{
res.writeHead(200,{"Content-Type":"text/html;charset=utf-8"})
res.write(`<html>
<p>hello geyao</p>
<div>大家好</div>
</html>`)
res.end()
}).listen(3002,()=>{
console.log("geyao.....")
})
运行结果
案例5
const http = require("http")
//创建服务器
http.createServer((req, res) => {
console.log(req)
if (req.url === "/home") {
}
res.writeHead(200, { "Content-Type": "text/html;charset=utf-8" })
res.write(renderHtml(req.url))
res.end()
}).listen(3002, () => {
console.log("geyao.....")
})
function renderHtml(url) {
switch (url) {
case "/home":
return `<html>
<p>hello home</p>
</html>`;
case "/list":
return `<html>
<p>hello list</p>
</html>`;
default:
return `<html>
<p>hello 404</p>
</html>`;
}
}
运行结果
案例6
const http = require("http")
//创建服务器
http.createServer((req, res) => {
console.log(req)
if (req.url === "/home") {
}
res.writeHead(renderStatus(req.url), { "Content-Type": "text/html;charset=utf-8" })
res.write(renderHtml(req.url))
res.end()
}).listen(3002, () => {
console.log("geyao.....")
})
function renderHtml(url) {
switch (url) {
case "/home":
return `<html>
<p>hello home</p>
</html>`;
case "/list":
return `<html>
<p>hello list</p>
</html>`;
default:
return `<html>
<p>hello 404</p>
</html>`;
}
}
function renderStatus(url){
var arr=["/home","/list"]
return arr.includes(url)?200:404
}
运行结果
