php 模拟POST提交的2种方法详解

一、通过curl函数
代码如下:
$post_data = array();
$post_data['clientname'] = "test08";
$post_data['clientpasswd'] = "test08";
$post_data['submit'] = "submit";
$url='http://xxx.xxx.xxx.xx/xx/xxx/top.php';
$o="";
foreach ($post_data as $k=>$v)
{
    $o.= "$k=".urlencode($v)."&";
}
$post_data=substr($o,0,-1);
$ch = curl_init();
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_URL,$url);
//为了支持cookie
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie.txt');
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
$result = curl_exec($ch);

二、通过fsockopen
代码如下:
$URL=‘http://xxx.xxx.xxx.xx/xx/xxx/top.php';
$post_data['clientname'] = "test08";
$post_data['clientpasswd'] = "test08";
$post_data['submit'] = "ログイン";
$referrer="";
// parsing the given URL
$URL_Info=parse_url($URL);
// Building referrer
if($referrer=="") // if not given use this script as referrer
$referrer=<PRE class=php name="code">{1}</PRE><BR>
SERVER["SCRIPT_URI"]; // making string from $dataforeach($post_data as $key=>$value)$values[]="$key=".urlencode($value); $data_string=implode("&",$values);// Find out which port is needed - if not given use standard (=80)if(!isset($URL_Info["port"]))$URL_Info["port"]=80;//
 building POST-request:$request.="POST ".$URL_Info["path"]." HTTP/1.1\n";$request.="Host: ".$URL_Info["host"]."\n";$request.="Referer: $referrer\n";$request.="Content-type: application/x-www-form-urlencoded\n";$request.="Content-length: ".strlen($data_string)."\n";$request.="Connection:
 close\n";$request.="\n";$request.=$data_string."\n";$fp = fsockopen($URL_Info["host"],$URL_Info["port"]);fputs($fp, $request);while(!feof($fp)) { $result .= fgets($fp, 128);}fclose($fp);
