嘗試完成授權時無法識別的臨時令牌：FITBIT4J

我正在嘗試使用fitbit4j爲fitbit創建應用程序。我發現他們的示例代碼在 https://github.com/apakulov/fitbit4j/blob/master/fitbit4j-example-client/src/main/java/com/fitbit/web/FitbitApiAuthExampleServlet.java 嘗試完成授權時無法識別的臨時令牌：FITBIT4J

當我試圖實現它時，我收到很多錯誤。下面是他們的doGet（）函數

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException { 
    FitbitAPIClientService<FitbitApiClientAgent> apiClientService = new FitbitAPIClientService<FitbitApiClientAgent>(
      new FitbitApiClientAgent(apiBaseUrl, fitbitSiteBaseUrl, credentialsCache), 
      clientConsumerKey, 
      clientSecret, 
      credentialsCache, 
      entityCache, 
      subscriptionStore 
    ); 
    if (request.getParameter("completeAuthorization") != null) { 
     String tempTokenReceived = request.getParameter(OAUTH_TOKEN); 
     String tempTokenVerifier = request.getParameter(OAUTH_VERIFIER); 
     APIResourceCredentials resourceCredentials = apiClientService.getResourceCredentialsByTempToken(tempTokenReceived); 

     if (resourceCredentials == null) { 
      throw new ServletException("Unrecognized temporary token when attempting to complete authorization: " + tempTokenReceived); 
     } 
     // Get token credentials only if necessary: 
     if (!resourceCredentials.isAuthorized()) { 
      // The verifier is required in the request to get token credentials: 
      resourceCredentials.setTempTokenVerifier(tempTokenVerifier); 
      try { 
       // Get token credentials for user: 
       apiClientService.getTokenCredentials(new LocalUserDetail(resourceCredentials.getLocalUserId())); 
      } catch (FitbitAPIException e) { 
       throw new ServletException("Unable to finish authorization with Fitbit.", e); 
      } 
     } 
     try { 
      UserInfo userInfo = apiClientService.getClient().getUserInfo(new LocalUserDetail(resourceCredentials.getLocalUserId())); 
      request.setAttribute("userInfo", userInfo); 
      request.getRequestDispatcher("/fitbitApiAuthExample.jsp").forward(request, response); 
     } catch (FitbitAPIException e) { 
      throw new ServletException("Exception during getting user info", e); 
     } 
    } else { 
     try { 
      response.sendRedirect(apiClientService.getResourceOwnerAuthorizationURL(new LocalUserDetail("-"), exampleBaseUrl + "/fitbitApiAuthExample?completeAuthorization=")); 
     } catch (FitbitAPIException e) { 
      throw new ServletException("Exception during performing authorization", e); 
     } 
    } 
}

當我運行它進入了 '其他' 部分首先代碼和我得到的URL 本地主機：8080/fitbitApiAuthExample completeAuthorization = &的oauth_token = 5bccadXXXXXXXXXXXXXXXXXXXXXXXXXX & oauth_verifier = h35kXXXXXXXXXXXXXXXXX，我也得到了fitbit登錄屏幕，當我登錄和自 'completeAuthorization == NULL'，

我t再次執行else部分。所以我手動添加一個值，以便它將進入'if'部分。因此，新的URL成爲 本地主機：8080/fitbitApiAuthExample completeAuthorization =成功&的oauth_token = 5bccadXXXXXXXXXXXXXXXXXXXXXXXXXX & oauth_verifier = h35kXXXXXXXXXXXXXXXXX，進入了 '如果' 部分。

現在是越來越異常「試圖完成授權時無法識別的臨時令牌：」我試過很多解決方法，但仍然無法理解的錯誤。

請幫忙。

解決了這個問題。當我重新加載servlet時，'apiClientService'變爲空。使它成員變量和一切開始工作。
