private - 如何通过Flickrj Api访问私有(private)照片？

Question

我正在通过 Flickr API 进行经过身份验证的调用来访问照片。但我只得到我的公开照片，而没有任何私有(private)照片。

下面给出的是我正在使用的代码，

Flickr f;
 RequestContext requestContext;
 String frob = "";
 String token = "";

 DocumentBuilder xmlParser = null;


 public void getImages() throws ParserConfigurationException, IOException, SAXException, FlickrException, URISyntaxException, NoSuchAlgorithmException
 {

  DocumentBuilderFactory dcb = DocumentBuilderFactory.newInstance();
        try {
            this.xmlParser = dcb.newDocumentBuilder();
        } catch (ParserConfigurationException ex) {
            ex.printStackTrace();
        }



  f = new Flickr("199d038ad88f6c6c377a4ab2341fb60f","4583b2386d3d6439",new REST()) ;
  Flickr.debugStream = false;
  requestContext = RequestContext.getRequestContext();
  AuthInterface authInterface = f.getAuthInterface();
  //PeopleInterface peopleInterface = f.getPeopleInterface();

  try {
  frob = authInterface.getFrob();
  } catch (FlickrException e) {
  e.printStackTrace();
  }
  System.out.println("frob: " + frob);


  java.net.URL url =authInterface.buildAuthenticationUrl(Permission.READ, frob);

  System.out.println(url.toExternalForm());

  Desktop desktop = Desktop.getDesktop();
  desktop.browse(url.toURI());


  // Get the response
  Auth auth = null ;
  String aLine = "";

  while(aLine.equals(""))
  {

   java.io.DataInputStream in = new java.io.DataInputStream(System.in);
   aLine = in.readLine();

  }

  auth =authInterface.getToken(frob);
  System.out.println("auth = "+auth);
  requestContext = RequestContext.getRequestContext();
  requestContext.setAuth(auth);
  f.setAuth(auth);

  UrlsInterface urlsInterface = f.getUrlsInterface();
  PhotosInterface photosInterface = f.getPhotosInterface();




  SearchParameters searchParams=new SearchParameters();
     searchParams.setSort(SearchParameters.INTERESTINGNESS_DESC);




     //Execute search with entered tags

     searchParams.setUserId(auth.getUser().getId());


     PhotoList photoList=photosInterface.search(searchParams, 10,1);


     if(photoList!=null){
        //Get search result and check the size of photo result
        for(int i=0;i<photoList.size();i++){
            Photo photo=(Photo)photoList.get(i);

           System.out.println(photo.getSmallSquareUrl());

        }

     }

可以通过编辑 flickrj 来访问私有(private)数据。

我在com.aetrion.flickr.photos.PhotosInterface中添加了auth_token参数:

public PhotoList search(SearchParameters params, int perPage, int page)
    throws IOException, SAXException, FlickrException {
    PhotoList photos = new PhotoList();

    List parameters = new ArrayList();
    parameters.add(new Parameter("method", METHOD_SEARCH));
    parameters.add(new Parameter("api_key", apiKey));

    parameters.addAll(params.getAsParameters());


    if (perPage > 0) {
        parameters.add(new Parameter("per_page", "" + perPage));
    }
    if (page > 0) {
        parameters.add(new Parameter("page", "" + page));
    }
    //
    String token = RequestContext.getRequestContext().getAuth().getToken();
    if (token != null)
      parameters.add(
        new Parameter(
          "auth_token", 
          RequestContext.getRequestContext().getAuth().getToken()
        )
      );
    //
    parameters.add(
        new Parameter(
            "api_sig",
            AuthUtilities.getSignature(sharedSecret, parameters)
        )
    );

    Response response = transport.get(transport.getPath(), parameters);

通过此更改，我能够获取我的私有(private)照片。

flickr api 文档说，“每个经过身份验证的调用都需要 auth_token 和 api_sig 参数“..但缺少了。

我从那里得到了这个想法:link text并使用 servlet 访问 flickr。
