一、使用node创建http服务器
javascript
var http = require('http');
// 获取到服务器实例对象
var server = http.createServer()
server.listen(8080, function() {
console.log('http://127.0.0.1:8080');
})
server.on('request', function(req, res){
console.log('request');
res.write('66666666888') // 响应数据
res.end() // 断开服务器
})二、服务器响应不同数据类型
javascript
var http = require('http');
// 获取到服务器实例对象
var server = http.createServer()
server.listen(8080, function() {
console.log('http://127.0.0.1:8080');
})
server.on('request', function(req, res){
console.log('request');
res.setHeader('Content-type', 'text/plain;charset=utf-8')
res.write('你好')
res.end() // 断开服务器
})
javascript
var http = require('http');
// 获取到服务器实例对象
var server = http.createServer()
server.listen(8080, function() {
console.log('http://127.0.0.1:8080');
})
server.on('request', function(req, res){
console.log('request');
// res.setHeader('Content-type', 'text/plain;charset=utf-8')
res.setHeader('Content-type', 'text/html;charset=utf-8')
res.write('<h1>你好</h1>')
res.end() // 断开服务器
})
javascript
var http = require('http');
var fs = require('fs')
// 获取到服务器实例对象
var server = http.createServer()
server.listen(8080, function() {
console.log('http://127.0.0.1:8080');
})
server.on('request', function(req, res){
if (req.url == '/') {
fs.readFile('./index.html', 'utf-8', function(err, data){
res.write(data)
res.end()
})
} else {
fs.readFile('./aa.jpg', function(err, data){
res.end(data)
})
}
})
三、http不同请求方法处理
javascript
var http = require('http');
var fs = require('fs')
var url = require('url')
// 获取到服务器实例对象
var server = http.createServer()
server.listen(8080, function() {
console.log('http://127.0.0.1:8080');
})
server.on('request', function(req, res){
console.log(11,req.method)
if (req.method === 'GET') {
console.log(url.parse(req.url, true).query.id)
if (req.url == '/') {
fs.readFile('./index.html', 'utf-8', function(err, data){
res.write(data)
res.end()
})
} else {
fs.readFile('./aa.jpg', function(err, data){
res.end(data)
})
}
} else if (req.method === 'POST') {
}
})四、接收处理post消息数据
javascript
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
</head>
<body>
<h1>你好啊 zm</h1>
<img src="./aa.jpg" alt="" width="50" height="50">
<div>
<form action="./" method="post">
<input type="text" name="username"> <br>
<input type="text" name="age">
<input type="submit" value="post提交">
</form>
</div>
</body>
</html>
javascript
var http = require('http');
var fs = require('fs')
// var url = require('url')
// 获取到服务器实例对象
var server = http.createServer()
server.listen(8080, function() {
console.log('http://127.0.0.1:8080');
})
server.on('request', function(req, res){
console.log('method:',req.method)
if (req.method === 'GET') {
// console.log(url.parse(req.url, true).query.id)
if (req.url == '/') {
fs.readFile('./index.html', 'utf-8', function(err, data){
res.write(data)
res.end()
})
} else {
fs.readFile('./aa.jpg', function(err, data){
res.end(data)
})
}
} else if (req.method === 'POST') {
// 请求体中
var data = ''
req.on('data', function(d){
data+=d
console.log(d)
})
req.on('end', function(){
console.log(require('querystring').parse(data))
})
}
})
五、服务器代码模块拆分
server.js
javascript
var http = require('http');
var fs = require('fs')
// var url = require('url')
var router = require('./router')
// 获取到服务器实例对象
var server = http.createServer()
server.listen(8080, function() {
console.log('http://127.0.0.1:8080');
})
server.on('request', function(req, res){
// console.log('request');
// // res.setHeader('Content-type', 'text/plain;charset=utf-8')
// res.setHeader('Content-type', 'text/html;charset=utf-8')
// res.write('<h1>你好</h1>')
// res.end() // 断开服务器
console.log('method:',req.method)
router(req, res)
})router.js
javascript
var fs = require('fs')
var controller = require('./controller')
module.exports = (req, res) => {
if (req.method === 'GET') {
// console.log(url.parse(req.url, true).query.id)
if (req.url == '/') {
controller.index(res)
} else {
fs.readFile('./aa.jpg', function(err, data){
res.end(data)
})
}
} else if (req.method === 'POST') {
// 请求体中
var data = ''
req.on('data', function(d){
data+=d
console.log(d)
})
req.on('end', function(){
controller.user(require('querystring').parse(data))
})
}
}controller.js
javascript
var fs = require('fs')
module.exports = {
index(res){
fs.readFile('./index.html', 'utf-8', function(err, data){
res.write(data)
res.end()
})
},
user(postData, res){
// 业务逻辑代码
console.log(postData)
}
}
