php 模拟POST提交的几种方法

1、curl

$post_data = array();$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cookiecurl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie.txt');curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);$result = curl_exec($ch);
2、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($URL);// Building referrerif($referrer=="") // if not given use this script as referrer$referrer=$_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);
