var url = require('url');
var qs = require('querystring');
var path = require("path") ;
var queryUrl = "" ;
var root = path.basename(queryUrl) ;
console.log(root) ; // bb?name=bigbear&memo=helloworld
var ext = path.extname(root) ;
console.log(ext || "Not Ext Name !") ; // Not Ext Name !
由于api过多,以上只列出来了常用的几个,大家需认真阅读文档。
二,综合栗子
场景描述------服务器接到不同情况的请求,通过 “Url” 分别做不同处理,代码如下:
(1),建立”index.html“
复制代码 代码如下:
<!doctype html>
<html>
<head>
<title>Bigbear</title>
<meta content="IE=8" http-equiv="X-UA-Compatible"/>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<style type="text/css">
div {
margin-top: 50px;
width: 100%;
margin: 0px;
height:120px;
line-height:120px;
color:#fff;
font-size:22px;
background:#ff9900;
text-align: center;
}
</style>
<script src="https://www.jb51.net/index.js"></script>
</head>
<body>
<div>Hello,大熊!</div>
</body>
</html>
(2),建立”index.js“
alert("Hello bb !") ; // 为了测试就这么一句代码
(3),建立”server.js“
复制代码 代码如下:
var http = require("http");
var fs = require('fs');
var url = require('url');
var path = require("path") ;
http.createServer(function(request,response) {
var method = request.method ;
method = method.toLowerCase() ;
var fileName = path.basename(request.url) ;
var extName = path.extname(fileName) ;
var root = "./" ;
if("get" == method){
if(extName){
fs.readFile("./" + fileName,"utf-8",function (error,data){
if(error)throw error ;
response.writeHead(200,{
"Content-Type": {
".css": "text/css" ,
".js" : "application/javascript"
}[extName]
}) ;
response.write(data) ;
response.end() ;
});
}
else{
fs.readFile(root + "index.html","utf-8",function (error,data){
if(error)throw error ;
response.writeHead(200,{
"Content-Type" : "text/html"
});
response.write(data) ;
response.end() ;
});
}
}
else if("post" == request.url){
// handle post here
}
}).listen(8888) ;
console.log("Web Server Running , Port On ---> 8888") ;
node server.js 运行一下。
三,总结一下
