Question

我正在使用gdata来获取app用户的gmail联系人照片，正是以下代码。但有时候抓取工作，有时它没有，并给我以下错误:(我怀疑太多令牌给谷歌服务器？虽然我还不太熟悉这个概念。但我确实需要取得所有用户联系照片，有办法解决它吗？）

提前谢谢你，

imageFetcher：GTMHTTPFetcher 0x145ea3300（https://www.google.com/m8/feeds/photos/media/XXXXX%40gmail.com/XXXXX）failedWithError：Error Domain = com.google.HTTPStatus Code = 503“无法完成操作。（com.google.HTTPStatus错误503。）”

if ([[[contact photoLink] ETag] length] ) {
                // imageData = [NSData dataWithContentsOfURL:photoURL];
                // requestForURL:ETag:httpMethod: sets the user agent header of the
                // request and, when using ClientLogin, adds the authorization header
                // get an NSURLRequest object with an auth token

                self.flyingtoken ++;
                NSURL *imageURL = [[contact photoLink] URL];
                GDataServiceGoogleContact *service = [self contactService];

                                                           httpMethod:nil];

                [request setValue:@"image/*" forHTTPHeaderField:@"Accept"];

                GTMHTTPFetcher *fetcher = [GTMHTTPFetcher fetcherWithRequest:request];
                [fetcher setAuthorizer:[service authorizer]];
                [fetcher beginFetchWithDelegate:self
                              didFinishSelector:@selector(imageFetcher:finishedWithData:error:)];

            }
