Facebook API：无法授权自己

I am working on my first Fb App. Just for testing purpose I went to my Account Settings and removed the app, now I can't access my own App and getting error:

API Error Code: 191 API Error Description: The specified URL is not owned by the application Error Message: redirect_uri is not owned by the application.

Using following code in PHP for Authorization:

$auth_url = "https://www.facebook.com/dialog/oauth?client_id=" . $app_id . "&redirect_uri=" . urlencode($my_url);
$signed_request = $_REQUEST["signed_request"];
list($encoded_sig, $payload) = explode('.', $signed_request, 2);
$data = json_decode(base64_decode(strtr($payload, '-_', '+/')), true);
if (empty($data["user_id"])) {
            echo("<script> top.location.href='" . $auth_url . "'</script>");
     } else {
            echo ("Welcome User: " . $data["user_id"]);
     }
   $access_token = $data["oauth_token"];
   $user = intval($data["user_id"]);

One thing I would add that if I access redirect_uri directly on browser then it shows dialog box to authorize my app but when I access my App URL on browser then it gives error and redirects to following URL

https://www.facebook.com/connect/uiserver.php?app_id=363045713726227&method=permissions.request&redirect_uri=https%3A%2F%2Fapps.facebook.com%2F363045713726227%2F&response_type=none&display=page&perms=user_photos&auth_referral=1

Without knowing the value of $my_url it's impossible to say, however, you've probably got $my_url set to a value that is outside of the "owned" domain that you have set in the developer application control panel.

The settings you are looking for are App Domain: Site URL: and Canvas URL:, please note that whilest Site URL: looks like it shouldn't be applicable, it actually is, in that you need a Site URL: set for the App Domain: to take affect.

In the domain URL, you must specify some url that you own. It can be edited from the Application Settings page. Else, for testing, you can use some facebook URL like ...&redirect_uri=http://www.facebook.com/home.php
