【问题描述】：

我使用下面的代码在他/她登录时获取 Facebook 用户信息。但问题是我无法获得用户的生日或名字。当我只想显示用户生日时，它只会显示一个空字符串。

【问题讨论】：

你用的是facebook最新的sdk
不，我使用的是 SDK 3.19.1
GraphUser 类在最新的 SDK 中不可用。
您确定 GraphUser 对象不为空吗？你能从中得到任何价值吗？
是的，只是名字和身份证而已

我找到了您需要为 User Graph Api 添加权限的答案。最后需要添加。

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

使用最新的Facebook SDK

并尝试使用以下代码获取用户信息

protected void connectToFacebook() {
ArrayList<String> list = new ArrayList<String>();
list.add("email");
// LoginManager.getInstance().logInWithReadPermissions(this, list);
LoginManager.getInstance().logInWithReadPermissions(this, Arrays.asList("email", "user_photos", "public_profile"));

LoginManager.getInstance().registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
    @Override
    public void onSuccess(LoginResult loginResult) {
        // App code
        GraphRequest request = GraphRequest.newMeRequest(loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() {
            @Override
            public void onCompleted(JSONObject json, GraphResponse response) {
                // Application code
                if (response.getError() != null) {
                    System.out.println("ERROR");
                } else {
                    System.out.println("Success");
                    String jsonresult = String.valueOf(json);
                    System.out.println("JSON Result" + jsonresult);

                    String fbUserId = json.optString("id");
                    String fbUserFirstName = json.optString("name");
                    String fbUserEmail = json.optString("email");
                    String fbUserProfilePics = "http://graph.facebook.com/" + fbUserId + "/picture?type=large";
                    callApiForCheckSocialLogin(fbUserId, fbUserFirstName, fbUserEmail, fbUserProfilePics, "fb");
                }
                Log.v("FaceBook Response :", response.toString());
            }
        });
        Bundle parameters = new Bundle();
        parameters.putString("fields", "id,name,email,gender, birthday");
        request.setParameters(parameters);
        request.executeAsync();


    }

    @Override
    public void onCancel() {
        // App code
        Log.v("LoginActivity", "cancel");
    }

    @Override
    public void onError(FacebookException exception) {
        // App code
        // Log.v("LoginActivity", "" + exception);
        Utilities.showToast(mActivity, "" + exception);
    }
   });
}
