java - 无法获取 Facebook ID 和电子邮件

Question

我遇到以下问题:授权后我需要获取 FB id 和电子邮件。这是我的代码:

@Override
            public void onSuccess(LoginResult loginResult) {

                final String[] email = new String[1];
                final String[] id = new String[1];

                GraphRequest request = GraphRequest.newMeRequest(
                        loginResult.getAccessToken(),
                        (object, response) -> {
                            try {
                                email[0] = object.getString(FB_EMAIL_PERMISSION);
                                id[0] = object.getString(FB_ID_PERMISSION);
                            } catch (JSONException e) {
                                e.printStackTrace();
                            }
                            response.getRawResponse();
                        });

                Bundle parameters = new Bundle();
                parameters.putString("fields", "id,email");
                request.setParameters(parameters);
                request.executeAsync();

                Bundle bundle = new Bundle();
                bundle.putString(EXTRA_TOKEN, loginResult.getAccessToken().getToken());
                bundle.putString(EXTRA_EMAIL, email[0]);
                bundle.putString(EXTRA_ID, id[0]);

                mPresenter.saveUserData(bundle);
            }

但是当我运行我的应用程序时，我没有得到这个字段。我检查了调试器和部分

GraphRequest request = GraphRequest.newMeRequest(
                        loginResult.getAccessToken(),
                        (object, response) -> {
                            try {
                                email[0] = object.getString(FB_EMAIL_PERMISSION);
                                id[0] = object.getString(FB_ID_PERMISSION);
                            } catch (JSONException e) {
                                e.printStackTrace();
                            }
                            response.getRawResponse();
                        });

根本没有被调用。我不明白为什么会这样。那么，这是怎么回事，我该如何解决呢？

UPD

也许，也许会有帮助，这是整个 Facebook 逻辑:

mCallbackManager = CallbackManager.Factory.create();
        mFacebookButton.setReadPermissions(Collections.singletonList(FB_EMAIL_PERMISSION));
        mFacebookButton.registerCallback(mCallbackManager, new FacebookCallback<LoginResult>() {
            @Override
            public void onSuccess(LoginResult loginResult) {

                final String[] email = new String[1];
                final String[] id = new String[1];

                GraphRequest request = GraphRequest.newMeRequest(
                        loginResult.getAccessToken(),
                        (object, response) -> {
                            try {
                                email[0] = object.getString(FB_EMAIL_PERMISSION);
                                id[0] = object.getString(FB_ID_PERMISSION);
                            } catch (JSONException e) {
                                e.printStackTrace();
                            }
                            response.getRawResponse();
                        });

                Bundle parameters = new Bundle();
                parameters.putString("fields", "id,email");
                request.setParameters(parameters);
                request.executeAsync();

                Bundle bundle = new Bundle();
                bundle.putString(EXTRA_TOKEN, loginResult.getAccessToken().getToken());
                bundle.putString(EXTRA_EMAIL, email[0]);
                bundle.putString(EXTRA_ID, id[0]);

                mPresenter.saveUserData(bundle);
            }

我对这个问题有一个想法，该请求是异步的，当我在 mPresenter.saveUserData(bundle); 行上放置断点时，信息尚未加载，但我该如何加载同步？或者也许我错了？

UPD 3

我按照以下方式更改了我的请求，但它仍然不起作用，并且在这部分中跳过了断点。

GraphRequest request = GraphRequest.newMeRequest(
                        loginResult.getAccessToken(),
                        (object, response) -> {
                            try {
                                if (response.getJSONObject() != null) {
                                    JSONObject data = response.getJSONObject();
                                    if (data.has(FB_EMAIL_PERMISSION)) {
                                        email[0] = response.getJSONObject().getString(FB_EMAIL_PERMISSION);
                                    }
                                    if (data.has(FB_ID_PERMISSION)) {
                                        id[0] = response.getJSONObject().getString(FB_ID_PERMISSION);
                                    }
                                }
                            } catch (JSONException e) {
                                e.printStackTrace();
                            }
                            response.getRawResponse();
                        });

这是权限的值:

private static final String FB_EMAIL_PERMISSION = "email";
private static final String FB_ID_PERMISSION = "id";

您是否为 Facebook 登录按钮添加了权限

fbLoginButton.setPermissions(Arrays.asList("public_profile,email,user_birthday"));
