【问题描述】：

我正在构建一个应用程序，它应该从 Facebook 请求事件。

我收到消息：

Response: responseCode:200, graphObject: null, errorHttpStatus:-1, errorCode:-1, errorType:null, errorMessage:com.facebook.FacebookException: 会话提供给处于未打开状态的请求。 , isFromCache:false

@覆盖 public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)

    super.onCreateView(inflater, container, savedInstanceState);
    View view = inflater.inflate(R.layout.event, container, false);
    
    requestData();
    
    eventName = (TextView) view.findViewById(R.id.eventName);
    eventOrt = (TextView) view.findViewById(R.id.eventOrt);
    eventZeit = (TextView) view.findViewById(R.id.eventZeit);
    eventBeschreibung = (TextView) view.findViewById(R.id.eventBeschreibung);
    
    
    return view;



private void requestData()
    
    Request request = new Request(
            Session.getActiveSession(), 
            "/0keepyourself/events", 
            null,
            HttpMethod.GET,
            new Request.Callback() 
                
                @Override
                public void onCompleted(Response response) 
                    // TODO Auto-generated method stub
                    Object obj = response;
                    Toast toast = Toast.makeText(getActivity(), (CharSequence) response.toString(), Toast.LENGTH_LONG);
                    toast.show();
                
            );
    request.executeAsync();
    String test = (String) request.getParameters().get("name");
    Toast.makeText(getActivity(), test, Toast.LENGTH_LONG).show();
    

【问题讨论】：

你看到我的回答了吗？

是的，对不起，谢谢它的工作:)

【参考方案1】：

提供给未打开状态的请求的会话

您需要先调用openForRead()，检查访问令牌的状态是否为OPENED，然后再调用request.executeAsync()。
