android - 在 Facebook Android API 中访问用户生日时出现不存在的字段错误

Question

我想访问用户的生日和性别，但是当我尝试访问生日时出现错误。我使用的是 Facebook SDK 版本 facebook-android-sdk:4.18.0。

它给我这个错误:

{Response: responseCode: 400, graphObject: null, error: {HttpStatus: 400, errorCode: 100, errorType: OAuthException, errorMessage: (#100) Tried accessing nonexisting field (user_birthday) on node type (User)}}

这是我的代码:

public class MainActivity extends AppCompatActivity {
    private CallbackManager callbackManager;
    private TextView info;
    private LoginButton loginButton;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        FacebookSdk.sdkInitialize(getApplicationContext());
        callbackManager = CallbackManager.Factory.create();

        setContentView(R.layout.activity_main);
        info = (TextView)findViewById(R.id.info);
        loginButton = (LoginButton)findViewById(R.id.login_button);
        loginButton.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) {
                                Log.v("LoginActivity", response.toString());

                                // Application code
                                String email = object.optString("email");
                                String birthday = object.optString("birthday");
                                String name = object.optString("name"); // 01/31/1980 format
                                info.setText("email:  " +
                                        email + "\n" +
                                        "birthday " + birthday+
                                "\n name"+name);
                            }
                        });
                Bundle parameters = new Bundle();
                parameters.putString("fields", "id,name,email,gender,user_birthday");
                request.setParameters(parameters);
                request.executeAsync();

            }

            @Override
            public void onCancel() {
                info.setText("Login attempt cancelled.");
            }

            @Override
            public void onError(FacebookException e) {
                info.setText("Login attempt failed.");
            }
        });
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        callbackManager.onActivityResult(requestCode, resultCode, data);
    }
}

在参数中你应该使用生日而不是用户生日:

parameters.putString("fields", "id, name, email, gender, birthday");

有关用户简介的可用字段，请参阅文档: https://developers.facebook.com/docs/graph-api/reference/user/
