在Android中登录Facebook期间，在jsonObject中只获取Id和Name

Question

我正试图使用facebook login从我的应用程序登录，但当我请求loginButton.setReadPermissions("public_profile")时，我在jsonObject中得到的响应只有id和名称，而没有其他内容。有人能找出问题出在哪里吗？这是我的密码。

public class LoginActivity extends AppCompatActivity {
LoginButton loginButton;
CallbackManager callbackManager;
String id, name, gender, ageRange;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    FacebookSdk.sdkInitialize(getApplicationContext());
    setContentView(R.layout.activity_login);
    loginButton=(LoginButton)findViewById(R.id.login_button);
    callbackManager= CallbackManager.Factory.create();
    loginButton.setReadPermissions("public_profile");
    loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
        @Override
        public void onSuccess(LoginResult loginResult) {
            AccessToken accessToken=loginResult.getAccessToken();
            GraphRequest graphRequest= GraphRequest.newMeRequest(accessToken, new GraphRequest.GraphJSONObjectCallback() {
                @Override
                public void onCompleted(JSONObject jsonObject, GraphResponse graphResponse) {
                    if (jsonObject!=null)
                    {
                        Log.e("JSON Object",jsonObject.toString());
                        Log.e("GraphResponse",graphResponse.toString());
                        try
                        {
                            id=jsonObject.getString("id");
                            name=jsonObject.getString("name");
                            gender=jsonObject.getString("gender");
                            ageRange=jsonObject.getString("age_range");
                        }
                        catch (JSONException e)
                        {
                            e.printStackTrace();
                        }
                    }
                }
            });
            graphRequest.executeAsync();
        }
        @Override
        public void onCancel() {
            Toast.makeText(getApplicationContext(),"Cancelled", Toast.LENGTH_SHORT).show();
        }
        @Override
        public void onError(FacebookException e) {
            Toast.makeText(getApplicationContext(),"Error while Connecting", Toast.LENGTH_SHORT).show();
        }
    });
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    callbackManager.onActivityResult(requestCode,resultCode,data);
}

使用图形API执行以下代码。

获取所有值，只要通过等参数即可

parameters.putString("fields"，"id，name，link，email，first_name，last_name，gender"(

全代码

public static CallbackManager callbackManager;
Button btn_login;

创建

FacebookSdk.sdkInitialize(getApplicationContext());
    btn_login = (Button) findViewById(R.id.btn_facebook);

    btn_login.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            callbackManager = CallbackManager.Factory.create();
            // loginButton.setReadPermissions(Arrays.asList("user_status"));
            // Set permissions
            LoginManager.getInstance().logInWithReadPermissions(
                    LoginActivity.this,
                    Arrays.asList("email", "public_profile"));


            LoginManager.getInstance().registerCallback(callbackManager,
                    new FacebookCallback<LoginResult>() {
                        @Override
                        public void onSuccess(LoginResult loginResult) {
                            System.out.println("Success");

                            GraphRequest request = GraphRequest.newMeRequest(
                                    loginResult.getAccessToken(),
                                    new GraphRequest.GraphJSONObjectCallback() {
                                        @Override

                                               GraphResponse response) {

                                            if (response.getError() != null) {
                                                // handle error
                                                System.out

                                                                    + jsonresult);

                        }
                        @Override
                        public void onCancel() {
                            Log.d("TAG_CANCEL", "On cancel");

                        }
                    });
        }
    });

onActivityResult

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