检查onedrive访问令牌状态

Question

如何检查一个驱动器访问令牌是否处于活动状态？我的代码不起作用:(需要帮助！

function check_one_drive_active(access_token){
    var od_api_root_url = "https://api.onedrive.com/v1.0/drive/root/";
    var od_url_param = "?access_token="+access_token;
    var od_api_url = od_api_root_url+od_url_param;

    alert(od_api_url);
    jQuery.ajax({
        url: od_api_url,
        dataType : "JSON",
        type : "POST",
        success: function(data){
            alert(data.error.code);
        }
    });
}
