php模拟post提交数据

php模拟post提交数据,用处很多,可用来网站的采集,登陆等等

2. //以程序登陆一个论坛登录为例
3. function bbslogin($user_login, $password, $host, $port = "80") {
4. //需要提交的post数据
5. $argv = array('cookie' => array('user_login' => $user_login, 'password' => $password, '_wp_http_referer' => '/bbpress/', 're' => '', 'remember' => true));
6. foreach ($argv['cookie'] as $key => $value) {
7. $params[] = $key . '=' . $value;
8. }
9. $params = implode('&', $params);
10. $header = "POST /bbpress/bb-login.php HTTP/1.1\r\n";
11. $header .= "Host:$host:$port\r\n";
12. $header .= "Content-Type: application/x-www-form-urlencoded\r\n";
13. $header .= "Content-Length: " . strlen($params) . "\r\n";
14. $header .= "Connection: Close\r\n\r\n";
15. $header .= $params;
16. $fp = fsockopen($host, $port);
17. fputs($fp, $header);
18. while (!feof($fp)) {
19. $str = fgets($fp);
20. //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
21. if (!(strpos($str, "Set-Cookie:") === false)) {
22. $tmparray = explode(" ", $str);
23. $cookiearray = explode("=", $tmparray[1]);
24. $cookiepaths = explode("=", $tmparray[6]);
25. $cookiename = urldecode($cookiearray[0]);
26. $cookievalue = urldecode(substr($cookiearray[1], 0, strlen($cookiearray[1]) - 1));
27. $cookietime = time() + 3600 * 24 * 7;
28. $cookiepath = urldecode(substr($cookiepaths[1], 0, strlen($cookiepaths[1]) - 1));
29. setcookie($cookiename, $cookievalue, $cookietime, $cookiepath);
30. }
31. }
32. fclose($fp);
33. }
34. ?>
