Facebook登录 - 获取onCancel中的用户数据-Java 学习之路

我在我的代码中添加了Facebook登录按钮 . 它运作良好 .

假设用户通过facebook登录并取消选中'user_friends'权限：将调用'onSuccess'函数，以便可以从loginResult中获取用户数据 .

下次当他打开应用程序时，他将获得facebook权限屏幕以允许'user_friends'权限 . 假设他再次取消选中它：'onCancel'函数将被调用，尽管用户现在将按预期自动登录（因为他从未注销） .

How can I get his data now in onCancel? (because I know that he is logged in but unchecked some permission)

The User logged in last time and not this time so onSuccess won't be called this time

mCallbackManager = CallbackManager.Factory.create();
mLoginButtonFacebook.registerCallback(mCallbackManager, new FacebookCallback<LoginResult>() {
    @Override
    public void onSuccess(LoginResult loginResult) {

    }
    @Override
    public void onCancel() {
        AccessToken token = AccessToken.getCurrentAccessToken();
        if (token != null) {            
            // here I would like to retrieve the user data
            // the user is logged in with canceled permissions
        }
    }
    @Override
    public void onError(FacebookException exception) {

    }
});

Succeeded! sorry for your time and thanks.

AccessToken accessToken = AccessToken.getCurrentAccessToken();

GraphRequest request = GraphRequest.newMeRequest(accessToken, new GraphRequest.GraphJSONObjectCallback() {
    @Override
    public void onCompleted(JSONObject object, GraphResponse response) {
        // object will contain the user data
    }
});
