php 获取session id,php用curl获取sessionid
http://www.111cn.net/phper/21/cfc64649f56d7b599cbb3cf15ade8cee.htm
$cookie_jar = tempnam(''./tmp'',''cookie'');
$ch = curl_init(); curl_setopt($ch,CURLOPT_URL,''http://******'');
curl_setopt($ch, CURLOPT_POST, 1);
$request = ''email_address=&password=&action='';
curl_setopt($ch, CURLOPT_POSTFIELDS, $request);
//把返回来的cookie信息保存在$cookie_jar文件中
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_jar);
//设定返回的数据是否自动显示
curl_setopt($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_COOKIEFILE, $cookie_jar);
$orders = curl_exec($ch2);
echo '''';
echo strip_tags($orders);
echo '''';
curl_close($ch2);
?>
方法2用fsockopen：
function GetWebContent($host, $method, $str, $sessid = '''')
{
$ip = gethostbyname($host);
//echo "ip=$ip
";
[email=$fp=@fsockopen($ip,80]$fp=@fsockopen($ip,80[/email]);
if (!$fp) return;
fputs($fp, "$method ");
fputs($fp, "Host: $host ");
if (!empty($sessid))
{
fputs($fp, "Cookie: PHPSESSID=$sessid; path=/; ");
}
if ( substr(trim($method),0, 4) == "POST")
{
fputs($fp, "Content-Length: ". strlen($str) . " "); // 别忘了指定长度
}
//fputs($fp, "Content-Type: application/x-www-form-urlencoded ");
fputs($fp, "Content-Type: application/x-www-form-urlencoded ");
fputs($fp, "User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; InfoPath.1) )");//add by Ew 071012
fputs($fp, "Connection: Keep-Alive ");
if ( substr(trim($method),0, 4) == "POST")
{
fputs($fp, $str." ");
}
while(!feof($fp))
{
$response .= fgets($fp);
}
$hlen = strpos($response," "); // LINUX下是 " "
$header = substr($response, 0, $hlen);
//echo "header=$header
";
$entity = substr($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'']."
";
