php模拟post提交数据,可用来网站的采集,登陆等等
[code]<?php
//以程序登陆一个论坛登录为例
function bbslogin($user_login, $password, $host, $port = "80") {
//需要提交的post数据
$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/1.1\r\n";
$header .= "Host:$host:$port\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Content-Length: " . strlen($params) . "\r\n";
$header .= "Connection: Close\r\n\r\n";
$header .= $params;
$fp = fsockopen($host, $port);
fputs($fp, $header);
while (!feof($fp)) {
$str = fgets($fp);
//以下是自己的逻辑代码,这里主要是模拟cookie,可用来同步登陆
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);
