ajax url在https url上发布

Question

Since I am using SSL connection in my website, I am trying to check the port where the user open the url (http/https):

if (isset($_SERVER['HTTPS']) &&
    ($_SERVER['HTTPS'] == 'on' || $_SERVER['HTTPS'] == 1) ||
    isset($_SERVER['HTTP_X_FORWARDED_PROTO']) &&
    $_SERVER['HTTP_X_FORWARDED_PROTO'] == 'https') {
  $protocol = 'https://';
}
else {
  $protocol = 'http://';
}

It works great for the link of external file like css and js.

However, by checking the port, I am not able to post something with ajax.

 <input type='submit' value="LOGIN" onclick="return checkLogin()">

        function checkLogin() {
            var cUsername = $('[id$=userEmail]').val();
            var cPassword = $('[id$=userPassword]').val();
            var cartItems = cartItemsToJSON();

            var dataString = "username=" + cUsername + "&password=" + cPassword  + "&cartItems=" + cartItems;
            $.ajax({
                type: "POST",
                url: "<?php echo $protocol; ?>"+location.hostname+" /member/actions/config-login2.php",
                data: dataString,
                cache: true,
                success: function(html) {

When I click login, it doesn't run to the `config-lgin2.php, but it only shows my credential on the browser.

I am wondering if I miss something here. Help please. Thanks in advance.

Dont use fully qualified URLs, please try with a relative URI.

Instead of specifying url as ....

  url: "<?php echo $protocol; ?>"+location.hostname+" /member/actions/config-login2.php"

specify as,

  url: "member/actions/config-login2.php"

in the AJAX call

If it does not work, JSONP is a nice alternative to look for
