php模拟post提交数据,用处很多,可用来网站的采集,登陆等等
- //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);
- }
- ?>

// PHP POST数据的三种方法
- // php有三种方法可以post数据,分别为Curl、socket、file_get_contents:
-
