php模擬post提交數據

php模擬post提交資料,用處很多,可用來網站的採集,登陸等等

//以程式登陸一個論壇登入為例
function bbslogin($user_login, $password, $host, $password, $host, $port = " 80") {
 //需要提交的post資料
 $argv = array('cookie' => array('user_login' => $user_login, 'password' => $password, '_wp_http_referer' => '/bbpress/', 're' => '', 'remember' => true));
 foreach ($argv['cookie'] as $key => $value) {
 $params[ ] = $key . '=' . $value;
 }
 $params = implode('&', $params);
 $header = "POST /bbpress/bb-login.php HTTP/ 1.1rn";
 $header .= "Host:$host:$portrn";
 $header .= "Content-Type: application/x-www-form-urlencodedrn";
 $header . = "Content-Length: " . strlen($params) . "rn";
 $header .= "Connection: Closernrn";
 $header .= $params;
 $fp = fsockopen($ host, $port);
 fputs($fp, $header);
 while (!feof($fp)) {
 $str = fgets($fp);
 //以下是自己的邏輯程式碼,這裡主要是模擬cookie,可用來同步登陸
 if (!(strpos($str, "Set-Cookie:") === false)) {
 $tmparray = explode(" ", $str);
 $cookiearray = explode("=", $tmparray[1]);
 $cookiepaths = explode("=", $tmparray[6]);
 $cookiename = urldecode($cookiearray[0]);
 $cookievalue = urldecode(substr($cookiearray[1], 0, strlen($cookiearray[1]) - 1));
 $cookietime = time() + 3600 * 24 * 7;
 $cookiepath = urldecode(substr($cookiepaths[1], 0, strlen($cookiepaths[1]) - 1));
 setcookie($cookiename, $cookievalue, $cookietime , $cookiepath);
 }
 }
 fclose($fp);
}
?>

// PHP POST資料的三種方法
// php有三種方法可以post資料,分別為Curl、socket、file_get_contents:


/**
 * Socket版本
 * 使用方法：
 * $post_string = "app=socket&version=beta";
 * request_by_socket('facebook.cn','/restServer.php',$post_string) ;
*/
function request_by_socket($remote_server, $remote_path, $post_string, $port = 80, $timeout = 30)
{
{
 $ if (!$socket) die("$errstr($errno)");

 fwrite($socket, "POST $remote_path HTTP/1.0rn");
 fwrite($socket, "User-Agent: Socket Examplern");
 fwrite($socket, "HOST: $remote_serverrn");
 fwrite( $socket, "Content-type: application/x-www-form-urlencodedrn");
 fwrite($socket, "Content-length: " . (strlen($post_string) + 8) . 'rn');
 fwrite($socket, "Accept:*/*rn");
 fwrite($socket, "rn");
 fwrite($socket, "mypost=$post_stringrn");
 fwrite($socket, "rn");
 $header = "";
 while ($str = trim(fgets($socket, 4096))) {
 $header .= $str;
 }
 $data = "";
 while (!feof($socket)) {
 $data .= fgets($socket, 4096);
 }
 return $data ;
}



/**
 * Curl版本
 * 使用方法：
 * $post_string = "app=request&version=beta";
 * request_by_curl('http://facebook.cn/restServer.php',$post_string );
*/
function request_by_curl($remote_server, $post_string)
{
 $ch = curl_in ;
 curl_setopt($ch, CURLOPT_URL, $remote_server);
 curl_setopt($ch, CURLOPT_POSTFIELDS, 'mypost=' . $post_string);
 curl_setopt($ch, CUR3); curl_setopt($ch, CURLOPT_USERAGENT, "Jimmy's CURL Example beta");
 $data = curl_exec($ch);
 curl_close($ch);
 return $data
 curl_close($ch);
 return $data
;
}


/**
 * 其它版本
 * 使用方法：
 * $post_string = "app=request&version=beta";
 * request_by_other('http://facebook.cn/restServer.php',$post_string );
*/
function request_by_other($remote_server, $post_string)
{
 $context = array(
 'http' => array(
 'method' => 'POST',
 'header' => 'Content-type: application/x-www-form-urlencoded' .
 'rn'.'User-Agent : Jimmy's POST Example beta ' .
 'rn'.'Content-length:' . strlen($post_string) + 8,
 'content' => 'mypost=' . $post_string)
 );
