试图登录到使用卷曲的网站

Question

我是新来卷曲并尝试过很多教程。最后一次尝试做我用下面的代码：

<?php 

    // INIT CURL 

    $url="http://www.justanswer.com/account/sign-in.aspx"; 

    function login($url) { 
    $result = ""; 
    $cookiePath = "/tmp/cookies.txt"; 
    // Initialize the page 
    $page = curl_init(); 
    // Set some options 
    curl_setopt($page, CURLOPT_COOKIESESSION, true); 
    curl_setopt($page, CURLOPT_REFERER, 'http://www.justanswer.com/login.aspx'); 
    curl_setopt($page, CURLOPT_FOLLOWLOCATION, false); 
    curl_setopt($page, CURLOPT_FRESH_CONNECT, true); 
    curl_setopt($page, CURLOPT_HEADER, true); 
    curl_setopt($page, CURLOPT_POST, true); 
    curl_setopt($page, CURLOPT_RETURNTRANSFER, true); 
    curl_setopt($page, CURLOPT_CONNECTTIMEOUT, 30); 

    $pattern = "#Set-Cookie: (.*?; path=.*?;.*?)\n#"; 
    preg_match_all($pattern, $result, $matches); 
    array_shift($matches); 
    $cookie = implode("\n", $matches[0]); 

    // Use the parsed cookies with the next request 
    curl_setopt($page, CURLOPT_COOKIE, $cookie); 

    curl_setopt($page, CURLOPT_COOKIESESSION, true); 
    curl_setopt($page, CURLOPT_FOLLOWLOCATION, false); 
    curl_setopt($page, CURLOPT_FRESH_CONNECT, true); 
    curl_setopt($page, CURLOPT_HEADER, false); 
    curl_setopt($page, CURLOPT_POST, false); 

    // Set the URL 
    curl_setopt($page, CURLOPT_URL, $url); 

    // Set the location of and send the cookies 
    curl_setopt($page, CURLOPT_COOKIEJAR, $cookiePath); 
    curl_setopt($page, CURLOPT_COOKIEFILE, $cookiePath); 

    // Send out POST data 
    curl_setopt($page, CURLOPT_POST, 1); 
    curl_setopt($page, CURLOPT_POSTFIELDS,       "__EVENTTARGET=&__EVENTARGUMENT=&__SSVIEWSTATE=18&__VIEWSTATE=&email=****&sign_in_type=returning&username=&password=****&remember=true&ctl00%24BodyContent%24btnLogin.x=99&ctl00%24BodyContent%24btnLogin.y=17&SC_SID=346833306&SC_GUID=d157264a-24e2-47c0-b545-259ea5298e19&JS_BOOL=true&__EVENTVALIDATION=%2FwEWAwL%2BraDpAgKUnpuXBgKp%2F%2BSDCG4uM7n2SYrFbuk10%2FLkC64jclbvH6dXKmxM06VHN92G"); 

    // Get the page 
    return $page; 

    } 

    $page = login($url); 

    // Go to the page and log in 
    curl_exec($page); 

    // Change the URL to the main page to check to see if the user is logged in 
    curl_setopt($page, CURLOPT_URL, "http://www.justanswer.com"); 

    // Print the output 
    print curl_exec($page); 

?> 

请有人可以解释我做错了，我复制使用在Firefox LIVE HTTP头扩展相同POST请求，它是成功的。

请建议

尝试包装形式变量数组，如：

$postVars = array("__EVENTTARGET" => "", 
        "__EVENTARGUMENT" => "", 
        "__SSVIEWSTATE" => "18", 
        "__VIEWSTATE"  => "", 
        "email"   => "****", 
        "sign_in_type" => "returning" 
        "foo" => "bar");
