目的是做一个分发的php脚本，根据客户端的不同需求，分发到不同的功能脚本。所以需要首先检验客户端发来的HTTP包中的请求类型，然后再进行分发。

分发脚本：

<?php/** This file is to distribute the requests to different servers , is divided by functions* Para : Http-Request* Data : 2014.5.5*/// include the mapping-arrayinclude './mapping/RequestType.php';include './mapping/MappingTable.php';// Get functionName from clients$functionName = $_POST['functionName'];// include the ReBuildHttpBag functioninclude 'ReBuildHttpBag.php';// Generate the para needed$curPageName = "/WinPhone/Distribute.php";$desPageName = $mapping[$functionName]['pageName'];$serverPath = $mapping[$functionName]['serverPath'];$serverPort = 80;ReBuildHttpBag($_GET, $curPageName, $desPageName, $serverPath, $serverPort);?>

ReBuildHttpBag定义：

<?phpfunction ReBuildHttpBag($argv=array(), $curPageName, $desPageName, $serverPath , $serverPort){$flag = 0;$post = '';$errno = '';$errstr = '';//构造要post的字符串foreach ($argv as $key=>$value) {if ($flag!=0) {$post .= "&";$flag = 1;}$post.= $key."=";$post.= urlencode($value);$flag = 1;}$length = strlen($post);//创建socket连接$fp = fsockopen($serverPath,$serverPort,$errno,$errstr,10) or exit($errstr."--->".$errno);//构造post请求的头$header = "POST ".$desPageName." HTTP/1.1\r\n";$header .= "Host:".$serverPath."\r\n";$header .= "Referer: ".$curPageName." \r\n";$header .= "Content-Type: application/x-www-form-urlencoded\r\n";$header .= "Content-Length: ".$length."\r\n";$header .= "Connection: Close\r\n\r\n";//添加post的字符串$header .= $post."\r\n";//发送post的数据fputs($fp,$header);$inheader = 1;while (!feof($fp)) {$line = fgets($fp,1024); //去除请求包的头只显示页面的返回数据if ($inheader && ($line == "\n" || $line == "\r\n")) {$inheader = 0;}if ($inheader == 0) {echo $line;}}fclose($fp);}?>
