重定向Ajax后获取URL

Question

To authenticate on Instagram I need to get an url sent me by Instagram as a redirect. I need to get the redirected url but I obtain ever null.

$.ajax({
url: "https://instagram.com/oauth/authorize/?client_id=e40f15a90**c89851d8a66&redirect_uri=http://examle.com&response_type=token",

success:function(result,status,xhr){
console.log(xhr.getResponseHeader('Location'));<---NULL
}

});

You can't get header info after redirect that would happen as a result of the request. Standard way is to open new child window with auth url (" https://instagram.com/oauth/authorize/?client_id=...response_type=token ", ) and retrieve token in redirect url, for example in onready event of http://examle.com after that send token to parent window and close popup (child) window.

Recommended Instagram auth is server side, so consider to use it.
