node.js 接收get请求

Get 请求的相关方法一定在http.ServerRequest下，ServerRequest有data、end、close3个事件，method、url、headers、trailers、httpVersion、connection6个属性，setEncoding、pause、resume3个方法。url属性下有一段说明描述了怎么解析get请求：

request.url#

Request URL string. This contains only the URL that is present in the actual HTTP request. If the request is:

GET /status？name=ryan HTTP/1.1
 Accept: text/plain

Then request.url will be:"/status？name=ryan"If you would like to parse the URL into its parts, you can use require（"url"）.parse（request.url）. Example:

node> require（"url"）.parse（"/status？name=ryan"） { href: "/status？name=ryan", search: "？name=ryan", query: "name=ryan", pathname: "/status" }

If you would like to extract the params from the query string, you can use therequire（"querystring"）.parse function, or pass true as the second argument to require（"url"）.parse. Example:

node> require（"url"）.parse（"/status？name=ryan", true） { href: "/status？name=ryan", search: "？name=ryan", query: { name: "ryan" }, pathname: "/status" }

说明中提到了require（"url"）和require（"querystring"）可以分别查看API的URL和Query Strings小节
按照说明试一下吧（node> 表示在命令行里敲代码）
那就结合 hello world 写一个动态的hello world[javascript]

var http = require（"http"）;
var server = http.createServer（）;
server.on（"request",function （req, res）{
res.writeHead（200, {"Content-Type": "text/plain"}）;
var name = require（"url"）.parse（req.url,true）.query.name
res.end（"Hello World " + name）;
}）;
server.listen（1337, "127.0.0.1"）;
console.log（"Server running at http://127.0.0.1:1337/"）;

将以上代码保存到 example3.js文件中，在cmd中敲入node example3.js

在浏览器地址栏中敲入 http://127.0.0.1:1337/hello？name=myname
挺简单的，下一节讲复杂的post http://www.linuxidc.com/Linux/2012-02/53535.htm
