php模拟用户发送post数据方法

我们经常会听人说利用php模拟用户发送post数据,今天出于好奇我找了两个用不同方法来实例post数据的方法，有需要了解的朋友可以看看.

<script>ec(2);</script>

使用 PHP 向页面 POST 数据

代码如下

复制代码

function socketPost($url, $data, &$ret) {  $urlArr = parse_url($url);  $host = $urlArr['host'];  $port = isset($urlArr['port'])?$urlArr['port']:80;  $path = isset($urlArr['path'])?$urlArr['path']:"/";  $fp = fsockopen($host, $port, $errno, $errstr, 30);  if (!$fp)  {      echo "$errstr ($errno) n";   return false;  }  else  {      $out = "POST $path HTTP/1.1rn";      $out .= "Host: $hostrn";   $out .= "Content-Type: application/x-www-form-urlencodedrn";   $out .= "Content-Length: ".strlen($data)."rn";      $out .= "Connection: Keep-Alivernrn";   $out .= $data;   $ret = "";      fwrite($fp, $out);      while (!feof($fp))   {          $ret .= fgets($fp, 128);      }      fclose($fp);  }  return true; } ?>

如果post报错，把$out .= "Connection: Keep-Alivernrn";中的Keep-Alive改成Close

利用php的socket模拟发送post数据的一个实例

 

代码如下

复制代码

$domain = "127.0.0.1";   $port = 80;   $uri = "/ly/post.php";   $data="txtName=111&txtEmail=222@1.net&rabSex=%D0%A1%BD%E3&txtFrom=%BD%AD%CE%F7%C1%FA%C4%CF&txtQq=2222&txtUrl=33333333&txtFace=images%2Fface%2Fface05.gif&txtEm=images%2Fem%2Fem01.gif&txtBody=rrr";   $protocolstr ="POST {$uri} HTTP/1.1rnHost: {$domain}rnContent-type: application/x-www-form-urlencodedrnContent-length: " . strlen($data) . "rnReferer: http://10.10.10.10/ly/index.phprnUser-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; SV1; .NET CLR 1.1.4322)rnAccept: */*rnrn{$data}rnrn";         $sock = fsockopen($domain, $port, $errno, $errstr, 30);   if (!$sock) die("$errstr ($errno)n");   fputs($sock, $protocolstr);      $headers = "";   while ($str = trim(fgets($sock, 4096)))     $headers .= "$strn";      $body = "";   while (!feof($sock))     $body .= fgets($sock, 4096);   fclose($sock);      echo " Response header: n";   echo $headers;   echo "n";      echo " Response body: n";   echo $body;   ?>

在这里我们就不讲关于fsockopen fwrite这些函数的用法了，只讲述模仿过程，有需要的可参考了下。
