Question

嗨，我正在玩新的Facebook Android SDK。我无法弄清楚的一件事是我如何要求电子邮件地址。我尝试了以下但它返回了除电子邮件地址以外的所有字段的值。我想我可能需要单独询问电子邮件地址，但不确定如果我使用LoginFragment，我该怎么做。

Request request = Request.newMeRequest(session, new GraphUserCallback() {

    @Override
    public void onCompleted(GraphUser user, Response response) {
        profilePictureView.setUserId(user.getId());
        userNameView.setText(user.getName());
    }
});

String NAME = "name";
String ID = "id";
String PICTURE = "picture";
String EMAIL = "email";
String FIELDS = "fields";
String REQUEST_FIELDS = TextUtils.join(",", new String[] {
    ID, NAME, PICTURE, EMAIL
});

Bundle parameters = new Bundle();
parameters.putString(FIELDS, REQUEST_FIELDS);
request.setParameters(parameters);
Request.executeBatchAsync(request);

感谢任何帮助。感谢

执行以下操作：

设置上述权限后，通过以下方式访问电子邮件：。user.asMap（）得到（ “电子邮件”））;

参见下面的示例

@Override
protected void onSessionStateChange(SessionState state, Exception exception) {

    // user has either logged in or not ...
    if (state.isOpened()) {
        // make request to the /me API
        Request request = Request.newMeRequest(this.getSession(),
                new Request.GraphUserCallback() {
                    // callback after Graph API response with user object

                    @Override
                    public void onCompleted(GraphUser user,
                            Response response) {
                        // TODO Auto-generated method stub
                        if (user != null) {
                            TextView etName = (TextView) findViewById(R.id.etName);

                            etName.setText(user.getName() + ","
                                    + user.getUsername() + ","
                                    + user.getId() + "," + user.getLink()
                                    + "," + user.getFirstName()+ user.asMap().get("email"));

                        }
                    }
                });
        Request.executeBatchAsync(request);
    }
}

当您打开会话时，请尝试在权限列表中包含“email”。

如果您使用的是LoginButton，请执行以下操作：

loginButton.setReadPermissions(Arrays.asList("email"));

如果您自己打开会话，请执行以下操作：

session.openForRead(new Session.OpenRequest(this).setPermissions(Arrays.asList("email")));

您可以使用以下代码试验请求/权限：https://developers.facebook.com/tools/explorer/

使用这些权限成功登录后，请再次尝试请求，包括电子邮件字段。

如果您使用com.facebook.widget.LoginButton，则应在此Facebook返回电子邮件后设置此片段的权限。这是工作代码：

LoginButton authButton = findViewById(R.id.sign_in_facebook);
    List<String> permissions = new ArrayList<>();
    permissions.add("public_profile");
    permissions.add("email");
    permissions.add("user_birthday");
    authButton.setReadPermissions(permissions);`

修改 Facebook更新了它的sdk，这促进了它的工作。从4.x版本（changelog）开始，您可以在需要它的不同位置初始化sdk，而不是以非常简单的方式使用它。这是样本：

FacebookSdk.sdkInitialize(getActivity().getApplicationContext()); CallbackManager callbackManager = CallbackManager.Factory.create(); LoginManager.getInstance().registerCallback(callbackManager, new FacebookCallback<LoginResult>() { @Override public void onSuccess(LoginResult loginResult) { GraphRequest request = GraphRequest.newMeRequest( loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() { @Override public void onCompleted(JSONObject object, GraphResponse response) { String email = object.optString("email"); String uid = object.optString("id"); loginPresenter.loginBySocial(email, uid); } }); Bundle parameters = new Bundle(); parameters.putString("fields", "email"); request.setParameters(parameters); request.executeAsync(); } @Override public void onCancel() { //your code } @Override public void onError(FacebookException exception) { //your code } });

我找到了一个解决方案：它有效

LoginFragment loginFragment = new LoginFragment() {

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
                View v = super.onCreateView(inflater, container, savedInstanceState);
                setReadPermissions(Arrays.asList("email"));
                return v;
            }
        };
