Question

我正在使用此代码，但收到无效范围错误

我想访问这个名字，姓氏和电子邮件。

任何人都可以帮我解决这个问题。

是因为facebook中的权限更改？

或其他什么？

我是否需要添加其他内容。

    public class MainActivity extends AppCompatActivity {

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

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

        callbackManager = CallbackManager.Factory.create();

        final LoginButton loginButton= (LoginButton)findViewById(R.id.loginButton);
        loginButton.setReadPermissions(Arrays.asList("email","name"));
        loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
            @Override
            public void onSuccess(LoginResult loginResult) {


                String accessToken = loginResult.getAccessToken().getToken();

                GraphRequest request= GraphRequest.newMeRequest(loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() {
                    @Override
                    public void onCompleted(JSONObject object, GraphResponse response) {
                        progressDialog.dismiss();
                        getData(object);
                    }
                });
                Bundle parameters = new Bundle();
                parameters.putString("fields","id,email,first_name,last_name");
                request.setParameters(parameters);
                request.executeAsync();
            }
        });

    }


    private void getData(JSONObject object)
    {
        try{
            email.setText(object.getString("email"));
            first_name.setText(object.getString("first_name"));
            last_name.setText(object.getString("last_name"));
        }
        catch (Exception e)
        {
            e.printStackTrace();
        }
    }

}

Answer 1

取而代之的是

first_name.setText(object.getString("first_name"));
            last_name.setText(object.getString("last_name"));
        }

你应该直接从facebeook获得名称

 facebookUser.name = object.getString("name");

尝试检查并获取名字和姓氏，你应该拆分它。

我已经通过电子邮件许可通过名称，删除它后不需要。谢谢你的回答

Answer 3

loginButton.setReadPermissions("public_profile");

设置此权限并使用此

protected void getUserDetails(LoginResult loginResult) {
        GraphRequest data_request = GraphRequest.newMeRequest(
                loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() {
                    @Override
                    public void onCompleted(
                            JSONObject json_object,
                            GraphResponse response) {

   //here is your login is success now your requirement is start From here
   //do your work
    Log.e("String Response from Facebook:>",json_object.toString())


                    }

                });
        Bundle permission_param = new Bundle();
  //width and height is optional parameters
        permission_param.putString("fields", "id,name,email,picture.width(120).height(120)");
        data_request.setParameters(permission_param);
        data_request.executeAsync();

获取first_name，last_name facebook的范围无效
