我在登录HTTPS登录URL时遇到curl发送问题。我正在尝试登录该站点并尝试在登录后显示页面。但是Curl给我HTTP 302错误。

我正在获取错误：

    function login($url,$data){
    $fp = fopen("cookie.txt", "w");
    fclose($fp);
    $login = curl_init();
    curl_setopt($login, CURLOPT_COOKIEJAR, "cookie.txt");
    curl_setopt($login, CURLOPT_COOKIEFILE, "cookie.txt");
    curl_setopt($login, CURLOPT_TIMEOUT, 40000);
    curl_setopt($login, CURLOPT_RETURNTRANSFER, TRUE);
    curl_setopt($login, CURLOPT_URL, $url);
    curl_setopt($login, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($login, CURLOPT_SSL_VERIFYHOST, false);
    curl_setopt($login, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
    curl_setopt($login, CURLOPT_FOLLOWLOCATION, TRUE);
    curl_setopt($login, CURLOPT_POST, TRUE);
    curl_setopt($login, CURLOPT_POSTFIELDS, $data);
    ob_start();
    return curl_exec ($login);
    ob_end_clean();
    curl_close ($login);
    unset($login);
