Question

我正在开发使用facebook sdk的新Android应用程序。我想获取用户朋友列表，我这样做：

Request request = Request.newMyFriendsRequest(
                        Session.getActiveSession(),
                        new Request.GraphUserListCallback() {
                            public void onCompleted(List<GraphUser> paramAnonymousList,
                                    Response paramAnonymousResponse) {
                                Toast.makeText(getApplicationContext(),
                                        paramAnonymousList.toString(),
                                        Toast.LENGTH_SHORT).show();
                                Log.e(TAG, paramAnonymousList.toString()
                                        + paramAnonymousResponse.toString());
                            }
                        });
                request.executeAsync();

然而，当我运行应用程序时，我会得到类似的东西：

GraphObjectList{itemType=GraphUser, state=[]}{Response: responseCode: 200, graphObject: GraphObject{graphObjectClass=GraphObject, state={"data":[]}}, error: null, isFromCache:false}

我试图在不在开发模式的应用程序中运行此代码并且它工作正常 - 我能够获取用户的数据。可能是响应代码200的原因是什么。根据：https://developers.facebook.com/docs/graph-api/using-graph-api/v2.0响应代码200属于facebook权限错误。但是要获取用户的朋友列表，我不必提供任何特定权限，那么这个响应的原因是什么？

提前致谢

Answer 1

HTTP 200表示您的请求正常。

真正的问题是Facebook API v2.0。应用无法检索用户的完整朋友列表，只有已使用该应用的朋友。即使您的应用程序仍在v1.0中，5月1日之后首次登录的用户也会获得v2.0行为。

参考：https://developers.facebook.com/docs/graph-api/reference/v2.0/user/friends

干杯！

我已经这样做了，并且在Facebook SDK 4.18.0

中完美运行

public class SignIn extends AppCompatActivity {

    CallbackManager callbackManager;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //before set conteview
        FacebookSdk.sdkInitialize(getApplicationContext());
        //  AppEventsLogger.activateApp(this);
        callbackManager = CallbackManager.Factory.create();
        setContentView(R.layout.activity_signin);

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

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

        loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
            @Override
            public void onSuccess(LoginResult loginResult) {

                GraphRequest graphRequest=GraphRequest.newMeRequest(loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() {
                    @Override
                    public void onCompleted(JSONObject jsonObject, GraphResponse graphResponse) {

                        Log.d("Graph Response",graphResponse.toString());

                        String myCustomizedResponse = graphResponse.getJSONObject().toString();

                        Log.d("Ketan_Ramani",graphResponse.getJSONObject().toString());

                        try {
                            JSONObject obj = new JSONObject(myCustomizedResponse);

                            String id = obj.getString("id");
                            String first_name = obj.getString("first_name");
                            String last_name = obj.getString("last_name");
                            String email = obj.getString("email");

                            Log.d("Id",id);
                            Log.d("FirstName",first_name);
                            Log.d("LastName",last_name);
                            Log.d("Email",email);

                        } catch (JSONException e) {
                            Utils.hide_dialog();

                            e.printStackTrace();
                        }
                    }
                });

                Bundle parameters = new Bundle();
                parameters.putString("fields", "id,name,first_name,last_name,email");
                graphRequest.setParameters(parameters);
                graphRequest.executeAsync();
            }

            @Override
            public void onCancel() {
                // App code
            }

            @Override
            public void onError(FacebookException exception) {
                // App code
            }
        });
    }

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