realization

Summary: this method is used to return the logical judgment of whether the user logs in, and it is also an abstract method. Therefore, we also need to implement its specific logic in the business layer. Then we rewrite the onloginedclick method and onnologinedclick method, in which the onloginedclick method is the callback method after the user logs in, The onnologinedclick method is the callback method executed after the user is not logged in
