HTTP 302 Google Drive API push bildirimleri gönderdiğinde

Question

Bir dosya için push bildirimlerini etkinleştirmek üzere Google Drive API'sini aramayı başardım.

push bildirimleri kurma kod şuna benzer: Ben cevap olarak bu olsun benim tarayıcı ve günlük gelen servlet'ler doGet denilen ettikten sonra

public class SampleServlet extends AbstractAppEngineAuthorizationCodeServlet { 
    private final static Logger logger = Logger.getLogger(SampleServlet.class.getName()); 
    private static final long serialVersionUID = 1L; 
    // Constants omitted 

    @Override 
    public void doGet(HttpServletRequest req, HttpServletResponse resp) 
      throws IOException, ServletException { 

     AuthorizationCodeFlow authFlow = initializeFlow(); 
     Credential credential = authFlow.loadCredential(getUserId(req)); 

     StringBuilder resultFromWatch = new StringBuilder(); 
     Drive drive = new Drive.Builder(Utils.HTTP_TRANSPORT, Utils.JSON_FACTORY, credential).setApplicationName("t").build(); 

     try { 
      Optional<Channel> channel = watchFile(drive, FILE_ID, CHANNEL_ID, "web_hook", "https://mydomain.appspot.com/drive"); 
      String channelStringTmp; 
      if (channel.isPresent()) { 
       channelStringTmp = channel.get().toString(); 
      } else { 
       channelStringTmp = "null..."; 
      } 
      resultFromWatch.append(channelStringTmp); 
     } catch (Exception e) { 
      resultFromWatch.append(e.getMessage()); 
     } 

     final UserService userService = UserServiceFactory.getUserService(); 
     final String thisUrl = req.getRequestURI(); 
     // Send the results as the response 
     PrintWriter respWriter = resp.getWriter(); 
     resp.setStatus(200); 
     resp.setContentType("text/html"); 

     addLoginLogoutButtons(req, resp, resultFromWatch, userService, thisUrl, respWriter); 
    } 

    private static Optional<Channel> watchFile(Drive service, String fileId, 
               String channelId, String channelType, String channelAddress) throws IOException { 
     final Channel returnValue; 
     Channel channel = new Channel(); 
     channel.setId(channelId); 
     channel.setType(channelType); 
     channel.setAddress(channelAddress); 
     Drive.Files tmp = service.files(); 
     returnValue = tmp.watch(fileId, channel).execute(); 
     return Optional.fromNullable(returnValue); 
    } 

    @Override 
    protected AuthorizationCodeFlow initializeFlow() throws ServletException, IOException { 
     return Utils.initializeFlow(); 
    } 

    @Override 
    protected String getRedirectUri(HttpServletRequest req) throws ServletException, IOException { 
     return Utils.getRedirectUri(req); 
    } 
}

    "expiration": "1484565747000", 
    "id": SAME_ID_AS_DEFINED_IN_SERVLET, 
    "kind": "api#channel", 
    "resourceId": A_NEW_ID, 
    "resourceUri": "https:\/\/www.googleapis.com\/drive\/v3\/files\/FILE_ID?acknowledgeAbuse=false&alt=json" 
} 

Sonraki adım dosya değiştirilirken bildirimleri alan denetleyicimi tanımlamak için. Bu gibi görünüyor:

@RestController 
@RequestMapping("/drive") 
public class ConcreteFileWatchController implements FileWatchController { 
    private final static Logger logger = Logger.getLogger(ConcreteFileWatchController.class.getName()); 

    @RequestMapping(method = RequestMethod.POST) 
    @ResponseStatus(value = HttpStatus.OK) 
    @Override 
    public void doGet(HttpServletRequest req, HttpServletResponse resp) throws IOException { 
     logger.info("Received watch call"); 
    } 
} 

Sonunda (Google App Engine üzerinde dağıtıldığı) uygulaması dağıtılan sonra dosyayı değiştirmeye çalışırsanız ve GAE içinde günlükleri baktıktan sonra ben bir çağrı olduğuna dair görebilirsiniz. Ancak, benim alma yöntemim yürütülmedi. Sadece bir 302'yi günlüğe bağlı büyük bir jsonla görüyorum. Benim yöntemimin çağrıldığını fark etmeme dışında bir hata göremiyorum. Yol günlüğünde bile doğru görünüyor. Ne yanlış yapabilirdim? hatayla ilgili olarak

Ben bu 302 mesajı görmek Google Cloud günlük sayfasına gidin:

Ekran Görüntüsü: Geri arama Bahar MVC aracılığıyla sunulmakta olduğundan

Answer 1

, başka bir yerde yapılandırılmış herhangi gizli yönlendirmelerin olmaması emin olun.

public class FileWatchTestServlet extends HttpServlet { 
    private final static Logger logger = Logger.getLogger(FileWatchTestServlet.class.getSimpleName()); 

    @Override 
    public void doPost(HttpServletRequest req, HttpServletResponse resp) throws IOException { 
     logger.info("Received watch call"); 
    } 
} 

Ve web.xml''deki

: Oraya bakmak gerekir böylece

<servlet> 
    <servlet-name>FileWatchTestServlet</servlet-name> 
    <servlet-class>com.mydomain.FileWatchTestServlet</servlet-class> 
</servlet> 
<servlet-mapping> 
    <servlet-name>FileWatchTestServlet</servlet-name> 
    <url-pattern>/drive</url-pattern> 
</servlet-mapping> 

302 uzağa giderse, konu, Bahar MVC'ın memuru ile Önce normal bir servlet'dir kullanarak geri arama test etmelidir Yönlendirmeye neden olabilecek her şey için (örneğin, sizin bakış açınız).
