php模拟登录 获取SESSIONID,并则在读取网页的时候发送
php模拟登录的两种方法
方法1用curl:
一.先开启php curl函数库的步骤
1).去掉windows/php.ini 文件里;extension=php_curl.dll前面的; ? ?/*用 echo phpinfo();查看php.ini的路径*/
2).把php5/libeay32.dll,ssleay32.dll复制到系统目录windows/下
3).重启apache
二.例子
例子:
<?php
$_jar = tempnam('./tmp','');
$ch = curl_init(); curl_setopt($ch,CURLOPT_URL,'http://******');
curl_setopt($ch, CURLOPT_POST, 1);
$request = 'email_address=&password=&action=';
curl_setopt($ch, CURLOPT_POSTFIELDS, $request);
//把返回来的信息保存在$_jar文件中
curl_setopt($ch, CURLOPT_JAR, $_jar);
//设定返回的数据是否自动显示
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
//设定是否显示头信息
curl_setopt($ch, CURLOPT_HEADER, false);
//设定是否输出页面内容
curl_setopt($ch, CURLOPT_NOBODY, false);
curl_exec($ch);
curl_close($ch); //get data after login
$ch2 = curl_init();
curl_setopt($ch2, CURLOPT_URL, 'http://*****');
curl_setopt($ch2, CURLOPT_HEADER, false);
curl_setopt($ch2, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch2, CURLOPT_FILE, $_jar);
$orders = curl_exec($ch2);
echo '';
echo strip_tags($orders);
echo '';
curl_close($ch2);?
?>
方法2用fsockopen:
<?php
?GetWebContent($host, $method, $str, $sessid = '')
{?
? ? $ip = gethostbyname($host);?
//echo "ip=$ip<br>";
? ? [email=$fp=@fsockopen($ip,80]$fp=@fsockopen($ip,80[/email]);?
? ? if (!$fp) return;?
? ? fputs($fp, "$method\r\n");?
? ? fputs($fp, "Host: $host\r\n");?
? ? if (!empty($sessid))?
? ? {?
? ? ? ? fputs($fp, ": PHPSESSID=$sessid; path=/;\r\n");?
? ? }?
? ? if ( substr(trim($method),0, 4) == "POST")?
? ? {?
? ? ? ? fputs($fp, "Content-Length: ". strlen($str) . "\r\n"); // ?别忘了指定长度?
? ? }
? ? //fputs($fp, "Content-Type: application/x-www-form-urlencoded\r\n\r\n");?
fputs($fp, "Content-Type: application/x-www-form-urlencoded\r\n");?
fputs($fp, "User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; InfoPath.1)\r\n)");//add by Ew 071012
fputs($fp, "Connection: Keep-Alive\r\n\r\n");
? ? if ( substr(trim($method),0, 4) == "POST")?
? ? {?
? ? ? ? fputs($fp, $str."\r\n");?
? ? }?
? ? while(!feof($fp))?
? ? {?
? ? ? ? $response .= fgets($fp);?
? ? }?
? ? $hlen = strpos($response,"\r\n\r\n"); // LINUX下是 "\n\n"?
? ? $header = substr($response, 0, $hlen);?
//echo "header=$header<hr><hr>";
? ? $entity = substr($response, $hlen + 4);?
? ? if ( preg_match('/PHPSESSID=([0-9a-z]+);/i', $header, $matches))?
? ? {?
? ? ? ? $a['sessid'] = $matches[1];?
? ? }?
? ? if ( preg_match('/Location: ([0-9a-z\_\?\=\&\#\.]+)/i', $header, $matches))?
? ? {?
? ? ? ? $a['location'] = $matches[1];?
? ? }
? ? $a['content'] = $entity; ? ??
? ? fclose($fp);?
? ? return $a;?
}
? $response = GetWebContent("$host","POST /$login_page HTTP/1.0", $str);//登入得到新的session_id
? //...可以在这里先保存session_id
? $response = GetWebContent("$host","GET /$somepage HTTP/1.0", '', $response['sessid']);//使用session_id访问页面
? echo $response['location'].$response['content']."<br>";?
?>
