一个测试HTML Method的例子

测试用代码：

<form method="POST">
    First name: <input type="text" name="fname" />
    Last name: <input type="text" name="lname" />
    <input type="submit" value="Submit" />
</form>

使用GET时传送给服务的数据：

GET /phpsocket/method.php?fname=steven&lname=jobs HTTP/1.1
Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/x-shockwave-flash, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, application/x-ms-application, application/x-ms-xbap, application/vnd.ms-xpsdocument, application/xaml+xml, */*
Referer: http://localhost/phpsocket/method.php?fname=steven&lname=jobs
Accept-Language: zh-cn
Accept-Encoding: gzip, deflate
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 2.0.50727; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729; .NET4.0C; .NET4.0E)
Host: localhost
Connection: Keep-Alive

使用POSTT时传送给服务的数据：

POST /phpsocket/method.php HTTP/1.1
Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/x-shockwave-flash, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, application/x-ms-application, application/x-ms-xbap, application/vnd.ms-xpsdocument, application/xaml+xml, */*
Referer: http://localhost/phpsocket/method.php
Accept-Language: zh-cn
Content-Type: application/x-www-form-urlencoded
Accept-Encoding: gzip, deflate
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 2.0.50727; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729; .NET4.0C; .NET4.0E)
Host: localhost
Content-Length: 23
Connection: Keep-Alive
Cache-Control: no-cache
Cookie: ZDEDebuggerPresent=php,phtml,php3

fname=steven&lname=jobs

两者比较结果：
1. GET提交时网址发生了变化，POST提交时网址没有变化；
2. GET数据以网址QueryString的方式提交给服务器，POST数据以Content的方式提交给服务器。
