我想尝试登录安全的https网站。我的代码运行成功为其他网站，但某些网站，窗体通过javascript提交它不工作。目前我使用下面的代码curl

I am trying to login a secure https website thorugh curl . my code is running successfully for other sites but some website where form is submitting through javascript its not working . currently i am using the following code for curl

# Define target page
$target = "https://www.domainname.com/login.jsf";
# Define the login form data
$form_data="enter=Enter&username=webbot&password=sp1der3";
# Create the cURL session
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $target); // Define target site
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); // Return page in string
curl_setopt($ch, CURLOPT_COOKIEJAR, "cookies.txt"); // Tell cURL where to write cookies
curl_setopt($ch, CURLOPT_COOKIEFILE, "cookies.txt"); // Tell cURL which cookies to send
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_POSTFIELDS, $form_data);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE); // Follow redirects
# Execute the PHP/CURL session and echo the downloaded page
$page = curl_exec($ch);

curl_close($ch);
?>    

，登录名如下

<form name="login" method="post" action="./servelet" >
Username=<input type="text" name="username" value="" >
Password=<input type="text" name="password" value="" >

$EMAIL            = '';
$PASSWORD         = '!';

$cookie_file_path = "/tmp/cookies.txt";
$LOGINURL         = "/login.jsf"; 
$agent            = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1";


// begin script
$ch = curl_init(); 

// extra headers
$headers[] = "Accept: */*";
$headers[] = "Connection: Keep-Alive";

// basic curl options for all requests
curl_setopt($ch, CURLOPT_HTTPHEADER,  $headers);
curl_setopt($ch, CURLOPT_HEADER,  0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);         
curl_setopt($ch, CURLOPT_USERAGENT, $agent); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); 
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file_path); 
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file_path); 

// set first URL
curl_setopt($ch, CURLOPT_URL, $LOGINURL);

// execute session to get cookies and required form inputs
$content = curl_exec($ch); 

 // grab the hidden inputs from the form required to login
$fields = getFormFields($content);
$fields['loginForm:userName'] = $EMAIL;
$fields['loginForm:password'] = $PASSWORD;

// get x value that is used in the login url
$x = '';
if (preg_match('/login\.jsf/i', $content, $match)) {
echo $x = $match[1];
}

//$LOGINURL   = "https://cart2.barnesandnoble.com/mobileacct/op.asp?stage=signIn";
   $LOGINURL   = "/pages/login.jsf";

// set postfields using what we extracted from the form
   $POSTFIELDS = http_build_query($fields); 

// change URL to login URL
curl_setopt($ch, CURLOPT_URL, $LOGINURL); 

// set post options
curl_setopt($ch, CURLOPT_POST, 1); 
curl_setopt($ch, CURLOPT_POSTFIELDS, $POSTFIELDS); 

// perform login
 $result = curl_exec($ch);  

 //print $result; 
$url2='';
curl_setopt($ch, CURLOPT_URL, $url2); 

$result2 = curl_exec($ch);  


function getFormFields($data)
{
if (preg_match('/(<form id="loginForm.*?<\/form>)/is', $data, $matches)) {
    $inputs = getInputs($matches[1]);

    return $inputs;
} else {
    die('didnt find login form');
}
}
