php 模拟POST提交的2种方法详解

一、通过curl函数

$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

$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);
