Question

我正在尝试使用facebook login从我的应用程序登录，但我在jsonObject回复的内容只是id和name，而我请求loginButton.setReadPermissions("public_profile")时没有其他内容。任何人都可以找出问题所在？这是我的代码。

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，请使用以下代码。

获取所有值，只需传递参数

parameters.putString（＆＃34;字段＆＃34;，＆＃34; id，name，link，email，first_name，last_name，gender＆＃34;）;
