php自動認可表單的方法(基於fsockopen與curl)_php技巧

本文執行個體講述了php基於fsockopen與curl實現自動認可表單的方法。分享給大家供大家參考，具體如下：

fsockopen和curl都可以做php自動認可表單

1. fsockopen方法:

php代碼:

<?php/*-----------------------------------------------------------*功能：使用PHP socke 向指定頁面提交資料*作者：果凍  說明：post($url, $data)**    $url   = 'http://www.xxx.com:8080/login.php';*    $data[user] = 'hong';*    $data[pass] = 'xowldo';*    echo post($url, $data);*-----------------------------------------------------------*/function post($url, $data) {  $url = parse_url($url);   if (!$url) return "couldn't parse url";   if (!isset($url['port'])) { $url['port'] = ""; }   if (!isset($url['query'])) { $url['query'] = ""; }  $encoded = "";   while (list($k,$v) = each($data)) {    $encoded .= ($encoded ? "&" : "");    $encoded .= rawurlencode($k)."=".rawurlencode($v);   }  $fp = fsockopen($url['host'], $url['port'] ? $url['port'] : 80);   if (!$fp) return "Failed to open socket to $url[host]";  fputs($fp, sprintf("POST %s%s%s HTTP/1.0n", $url['path'], $url['query'] ? "?" : "", $url['query']));  fputs($fp, "Host: $url[host]n");  fputs($fp, "Content-type: application/x-www-form-urlencodedn");  fputs($fp, "Content-length: " . strlen($encoded) . "n");  fputs($fp, "Connection: closenn");  fputs($fp, "$encodedn");  $line = fgets($fp,1024);   if (!eregi("^HTTP/1.. 200", $line)) return;  $results = ""; $inheader = 1;   while(!feof($fp)) {    $line = fgets($fp,1024);     if ($inheader && ($line == "n" || $line == "rn")) {    $inheader = 0;   }   elseif (!$inheader) {    $results .= $line;   }   }  fclose($fp);   return $results;}/*$url = 'http://video.xxx.com:80/game_vm.php';$data['gid'] = '1';echo post($url, $data);*/?>

2. Curl方法：

php代碼:

<?php  $url = 'http://localhost/curl/result.php';  $params = "param=123&param2=333"; //What will be posted  $user_agent = "Mozilla/5.0 (compatible; MSIE 5.01; Windows NT 5.0)";  $ch = curl_init();  curl_setopt($ch, CURLOPT_POST,1);  curl_setopt($ch, CURLOPT_POSTFIELDS,$params);  curl_setopt($ch, CURLOPT_URL,$url);  curl_setopt($ch, CURLOPT_USERAGENT, $user_agent);  curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);  $result=curl_exec ($ch); //execut  curl_close ($ch);  echo "Results: <br>".$result;?>

result.php (just for test)

<?phpprint_r($_POST);?>
