我想检查我的Bond是否为空或null和NULL值.

{
Bonds =(
      {
        DOB = "12/09/1988";
        about = "";
      }
      );
User =     {
    city = CA;
    email = "karmhadadmtl@gmail.com";
};
success = True;
}

第二次这种类型获取数据如何检查Bond键

{
Bonds = Null;
User =     {
    city = CA;
    email = "developer.i12@gmail.com";
};
success = True;
}
