url里的path和query-http和url模块
var http = require("http"),
url = require("url"),
fs = require("fs");
s1 = http.createServer(function (req, res) {
// res.write("<h1>hello yifei</h1>");
// res.end();
var urlObj = url.parse(req.url, true),
pathname = urlObj['pathname'], //path
query = urlObj['query']; //?后面的参数 {}类型
console.log(pathname);
console.log(query);
res.end();//终结请求
});
s1.listen(1234, function () {
console.log("http://127.0.0.1:1234?name=maotai&age=22");
});结果
返回html-fs模块
index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>test</title>
<link rel="stylesheet" href="css/base.css">
</head>
<body>
<h1>用户登录</h1>
<form action="/add.html" method="get">
<p>用户: <input type="text" name="username"></p>
<p>密码: <input type="text" name="password"></p>
<p><input type="submit"></p>
</form>
</body>
</html>
css/base.css
body{
background-color: #0086b3;
}node代码
var http = require('http'),
url = require('url'),
fs = require('fs');
s1 = http.createServer(function (req, res) {
var urlObj = url.parse(req.url, true),
pathname = urlObj['pathname'],
query = urlObj['query'];
console.log(pathname, query);
if (pathname === "/index.html") {
var con = fs.readFileSync("./index.html"); //读取html,返回
res.end(con);
return;
}
if (pathname === "/css/base.css") { //index.html里会调用css
con = fs.readFileSync("./css/base.css","utf-8");
res.end(con);
return;
}
});
s1.listen("1234", function () {
console.log("http://127.0.0.1:1234/index.html");
});
根据pathname返回不通的url
最简陋的实现(如果html不存在会报错)
var http = require("http"),
url = require("url"),
fs = require("fs");
s1 = http.createServer(function (req, res) {
var urlObj = url.parse(req.url),
pathname = urlObj['pathname'],
query = urlObj['query'];
pathname = "." + pathname;
var con = fs.readFileSync(pathname); //根据pathname返回不同的url
res.end(con);
return; //代表终结
});
s1.listen(1234, function () {
console.log("http://127.0.0.1:1234/index.html")
});
处理错误
var http = require("http"),
url = require("url"),
fs = require("fs");
s1 = http.createServer(function (req, res) {
var urlObj = url.parse(req.url),
pathname = urlObj['pathname'],
query = urlObj['query'];
try {
var con = fs.readFileSync('.'+pathname);
res.end(con);
} catch (e) {
res.end("request file is not fonund!")
}
return;
});
s1.listen(1234, function () {
console.log("http://127.0.0.1:1234/index.html")
});
处理mime
即不通类型不同的显示,如html css
谷歌浏览器会智能处理一些类型.
var http = require('http'),
url = require('url'),
fs = require('fs');
s1 = http.createServer(function (req, res) {
var urlObj = url.parse(req.url),
pathname = urlObj['pathname'],
query = urlObj['query'];
var reg = /\.(HTML|CSS|JS|JSON|TXT|ICO)/i;
var suffix = reg.exec(pathname)[1].toUpperCase();
var suffixMIME = 'text/plain';
if (reg.test(pathname)) {
switch (suffix) {
case "HTML":
suffixMIME = 'text/html';
break;
case "JS":
suffixMIME = 'text/javascript';
break;
case "CSS":
suffixMIME = 'text/css';
break;
case "JSON":
suffixMIME = 'application/json';
break;
case "ICO":
suffixMIME = 'application/octet-stream';
break;
}
}
try {
con = fs.readFileSync('.' + pathname);
res.writeHead(200, {'content-type': suffixMIME + ';charset=utf-8'});
res.end(con);
} catch (e) {
res.writeHead(404, {'content-type': 'text/plain;charset=utf-8'});
res.end("file not found")
}
});
s1.listen(1234, function () {
console.log("http://127.0.0.1:1234/index.html");
});
