Detailed explanation of nodejs rendering page resources through response writeback
This article mainly introduces the detailed explanation of nodejs rendering page resources through response writeback. Now I share it with you and give it as a reference.
We generally operate page rendering through the api provided by the node framework. How to use the original write-back method to achieve the same function?
The following is asynchronously reading a file through the node provided All content api readFile operates, the code is as follows:
html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie=edge"> <link rel="stylesheet" type="text/css" href="./static/style.css" rel="external nofollow" /> <title>Document</title> </head> <body> <p>这是一个p </p> <p>这是一个p </p> <p>这是一个p </p> <p>这是一个p </p> <p>这是一个p </p> <p>这是一个p </p> <p>这是一个p </p> <p>这是一个p </p> <p>这是一个p </p> <p>这是一个p </p> <p>这是一个p </p> <script type="text/javascript" src="./static/test.js"></script> </body> </html>
/static folder contains test.js and style.css files
p:nth-child(1){
font-size: 50px;
color: red;
}
p:nth-child(3){
font-size: 80px;
color: blue;
}
p:nth-child(6){
font-size: 100px;
color: blueviolet;
}app.js
// 搭建服务
var http = require('http');
var fs = require('fs');
var server = http.createServer();
server.on('listening',()=> {
console.log('server starts at localhost 8080');
})
server.listen('8080','localhost');
//监听服务
server.on('request',(req,res)=>{
if(req.url == '/') {//渲染html文件
fs.readFile('./html/node.html',(err,info)=>{
res.write(info);
res.end();
})
} else if(req.url.startsWith('/static')) {//统一渲染html需要的static静态文件到页面
fs.readFile(__dirname + req.url,(err,info) =>{
res.write(info);
res.end();
})
}
})The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
