我們經常會聽人說利用php模擬用戶發送post數據,今天出于好奇我找了兩個用不同方法來實例post數據的方法,使用 PHP 向頁面 POST 數據,代碼如下:

<?php

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)<br />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報錯,把$out .= "Connection: Keep-Alivernrn";中的Keep-Alive改成Close,利用php的socket模擬發送post數據的一個實例,代碼如下:

<?php

$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 "<h2>Response header:</h2>n";

echo $headers;

echo "n";

echo "<h2>Response body:</h2>n";

echo $body;

?>
