Question

我正在使用以下代码。我想要用户的出生日期，电子邮件和性别。请帮忙。如何检索这些数据？

这是片段中的onViewCreated()。

@Override
public void onViewCreated(View view, Bundle savedInstanceState) {

    // Setup TextView.
    mTextDetails = (TextView) view.findViewById(R.id.text_details);

    // Set up Login Button.
    LoginButton mButtonLogin = (LoginButton) view.findViewById(R.id.login_button);
    // setFragment only if you are using it inside a Fragment.
    mButtonLogin.setFragment(this);
    mButtonLogin.setReadPermissions("user_friends");
    mButtonLogin.setReadPermissions("public_profile");
    mButtonLogin.setReadPermissions("email");
    mButtonLogin.setReadPermissions("user_birthday");

    // Register a callback method when Login Button is Clicked.
    mButtonLogin.registerCallback(mCallbackManager, mFacebookCallback);

}

这是我的回调方法。

private FacebookCallback<LoginResult> mFacebookCallback = new FacebookCallback<LoginResult>() {
    @Override
    public void onSuccess(LoginResult loginResult) {
        Log.d("Shreks Fragment", "onSuccess");


        Profile profile = Profile.getCurrentProfile();
        Log.d("Shreks Fragment onSuccess", "" +profile);

        // Get User Name
        mTextDetails.setText(profile.getName() + "");

    }


    @Override
    public void onCancel() {
        Log.d("Shreks Fragmnt", "onCancel");
    }

    @Override
    public void onError(FacebookException e) {
        Log.d("Shreks Fragment", "onError " + e);
    }
};

Answer 1

这不是设置权限的正确方法，因为每次方法调用都会覆盖它们。

替换它：

mButtonLogin.setReadPermissions("user_friends");
mButtonLogin.setReadPermissions("public_profile");
mButtonLogin.setReadPermissions("email");
mButtonLogin.setReadPermissions("user_birthday");

使用以下方法，因为方法setReadPermissions()接受ArrayList：

loginButton.setReadPermissions(Arrays.asList(
        "public_profile", "email", "user_birthday", "user_friends"));

此处还有如何查询额外数据GraphRequest：

private LoginButton loginButton;
private CallbackManager callbackManager;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_login);

    loginButton = (LoginButton) findViewById(R.id.login_button);

    loginButton.setReadPermissions(Arrays.asList(
            "public_profile", "email", "user_birthday", "user_friends"));

    callbackManager = CallbackManager.Factory.create();

    // Callback registration
    loginButton.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 object, GraphResponse response) {
                            Log.v("LoginActivity", response.toString());

                            // Application code
                            String email = object.getString("email");
                            String birthday = object.getString("birthday"); // 01/31/1980 format
                        }
                    });
            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.getCause().toString());
        }
    });
}

修改

一个可能的问题是Facebook假定您的电子邮件无效。要测试它，请使用Graph API Explorer并尝试获取它。即使在那里，您也无法收到电子邮件，请在配置文件设置中进行更改，然后重试。这种方法解决了这个问题，一些开发人员评论了我的答案。

使用此代码段获取所有个人资料信息

private FacebookCallback<LoginResult> callback = new FacebookCallback<LoginResult>() {
        @Override
        public void onSuccess(LoginResult loginResult) {
            AccessToken accessToken = loginResult.getAccessToken();
            Profile profile = Profile.getCurrentProfile();

            // Facebook Email address
            GraphRequest request = GraphRequest.newMeRequest(
                    loginResult.getAccessToken(),
                    new GraphRequest.GraphJSONObjectCallback() {
                        @Override
                        public void onCompleted(
                                JSONObject object,
                                GraphResponse response) {
                            Log.v("LoginActivity Response ", response.toString());

                            try {
                                Name = object.getString("name");

                                FEmail = object.getString("email");
                                Log.v("Email = ", " " + FEmail);
                                Toast.makeText(getApplicationContext(), "Name " + Name, Toast.LENGTH_LONG).show();


                            } catch (JSONException e) {
                                e.printStackTrace();
                            }
                        }
                    });
            Bundle parameters = new Bundle();
            parameters.putString("fields", "id,name,email,gender, birthday");
            request.setParameters(parameters);
            request.executeAsync();


        }

        @Override
        public void onCancel() {
            LoginManager.getInstance().logOut();

        }

        @Override
        public void onError(FacebookException e) {

        }
    };

Answer 3

您无法在onSuccess()中获得个人资料，您需要实施ProfileTracker以及注册回调

mProfileTracker = new ProfileTracker() {
    @Override
    protected void onCurrentProfileChanged(Profile oldProfile, Profile newProfile) {
        // Fetch user details from New Profile
    }
};

也不要忘记处理profile tracker的开始和停止

现在您将拥有一个从中获取AccessToken的配置文件（解决了null配置文件的问题）。你只需要使用＆＃34; https://developers.facebook.com/docs/android/graph#userdata＆＃34;获取任何数据。

Answer 4

您可以使用GraphRequest类向Facebook Graph API发出调用以获取用户信息。有关详细信息，请参阅https://developers.facebook.com/docs/android/graph。

Answer 5

登录后

private void getFbInfo() {
    GraphRequest request = GraphRequest.newMeRequest(
            AccessToken.getCurrentAccessToken(),
            new GraphRequest.GraphJSONObjectCallback() {
                @Override
                public void onCompleted(
                        JSONObject object,
                        GraphResponse response) {
                    try {
                        Log.d(LOG_TAG, "fb json object: " + object);
                        Log.d(LOG_TAG, "fb graph response: " + response);

                        String id = object.getString("id");
                        String first_name = object.getString("first_name");
                        String last_name = object.getString("last_name");
                        String gender = object.getString("gender");
                        String birthday = object.getString("birthday");
                        String image_url = "http://graph.facebook.com/" + id + "/picture?type=large";

                        String email;
                        if (object.has("email")) {
                            email = object.getString("email");
                        }

                    } catch (JSONException e) {
                        e.printStackTrace();
                    }
                }
            });
    Bundle parameters = new Bundle();
    parameters.putString("fields", "id,first_name,last_name,email,gender,birthday"); // id,first_name,last_name,email,gender,birthday,cover,picture.type(large)
    request.setParameters(parameters);
    request.executeAsync();
}

Answer 7

这对我有用，希望能帮助别人（使用我自己的按钮而不是FB登录按钮）

CallbackManager callbackManager;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    FacebookSdk.sdkInitialize(getApplicationContext());
    setContentView(R.layout.activity_sign_in_user);



     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) {
                    try {
                        Log.i("RESAULTS : ", object.getString("email"));
                    }catch (Exception e){

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

        }

        @Override
        public void onCancel() {

        }

        @Override
        public void onError(FacebookException error) {
            Log.i("RESAULTS : ", error.getMessage());
        }
    });


}

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


boolean isEmailValid(CharSequence email) {
    return android.util.Patterns.EMAIL_ADDRESS.matcher(email).matches();
}

public void signupwith_facebook(View view) {

    LoginManager.getInstance().logInWithReadPermissions(this, Arrays.asList("public_profile","email"));
}
}

Answer 8

在单击按钮

上添加此行

loginButton.setReadPermissions（Arrays.asList（ “ public_profile”，“电子邮件”，“ user_birthday”，“ user_friends”））；

Answer 9

这是一个可行的解决方案（2019年）：将此代码放入您的登录逻辑中；

 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";
                        Log.d("SignUpActivity", "Email: " + fbUserEmail + "\nName: " + fbUserFirstName + "\nID: " + fbUserId);
                    }
                    Log.d("SignUpActivity", response.toString());
                }
            });
            Bundle parameters = new Bundle();
            parameters.putString("fields", "id,name,email,gender, birthday");
            request.setParameters(parameters);
            request.executeAsync();
        }

        @Override
        public void onCancel() {
            setResult(RESULT_CANCELED);
            Toast.makeText(SignUpActivity.this, "Login Attempt Cancelled", Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onError(FacebookException error) {
            Toast.makeText(SignUpActivity.this, "An Error Occurred", Toast.LENGTH_LONG).show();
            error.printStackTrace();
        }
    });

Answer 10

使用Profile类的FB静态方法getCurrentProfile（）来检索这些信息。

 Profile profile = Profile.getCurrentProfile();
 String firstName = profile.getFirstName());
 System.out.println(profile.getProfilePictureUri(20,20));
 System.out.println(profile.getLinkUri());
