复习:编写简单的http服务器
const http = require("http");
const ip = "192.168.25.128";
const port = 3000;
http.createServer((req,res)=>{
res.writeHead(200,{'content-type:':'text/html'});
res.write('hello');
res.end();
}).listen(port,ip,()=>{
console.log('server start');
});
改写程序
url地址访问
const http = require("http");
const url = require("url");
const ip = "192.168.25.128";
const port = 3000;
var f =function(req,res){
var pathname = url.parse(req.url).pathname;
res.write(pathname);
res.end();
}
var f2 = function(){
console.log('server');
}
http.createServer(f).listen(port,ip,f2);
文件操作
touch 创建空文件
获取文件内容
const http = require("http");
const url = require("url");
const fs = require("fs");
const ip = "192.168.25.128";
const port = 3000;
//fs.readFile('a.txt',(err,data)=>{
// if(err)throw err;
// console.log(data.toString());
// });
var data = fs.readFileSync('a.txt');//读取文件内容
var f =function(req,res){
var pathname = url.parse(req.url).pathname;
res.write(pathname);
res.write(data.toString());
res.end();
}
var f2 = function(){
console.log('server');
}
http.createServer(f).listen(port,ip,f2);
根据请求判断访问的模板
const http = require("http");
const url = require("url");
const fs = require("fs");
const ip = "192.168.25.128";
const port = 3000;
var server = new http.Server();
server.listen(port,ip);
server.on('req',function(req,res) {
var pathname = url.parse(req.url).pathname;
// var userurl = url.parse(pathname);
switch (pathname) {
case '' || '/':
fs.readFile('./index.html',function(err,content) {
if (err) {
console.log(err);
}else {
res.writeHead(200, {'Content-Type':'text/html:charset=utf-8'});
res.write(content);
res.end();
}
});
break;
default:
}
});
