Azure Server wirft Ausnahme nach bestimmten Nummern von API-Aufruf

Question

Ich habe eine API (MVC) erstellt und hostet es in Azure-Server. Die API empfängt jeweils 1 Bild und 1 Text. Es funktioniert ordnungsgemäß für den Einzelanruf oder den ersten Anruf, aber nach bestimmten Nummern von API-Aufruf unter Fehler.

Nach Microsoft.Azure.DocumentDB Installation:

Fehler:

Hier ist mein Code-Schnipsel:

var blobHelper = new BlobHelper(); 
var response = new UploadMediaResponse(); 
for (var i = 0; i<provider.Files.Count; i++) 
{ 
    Guid itemId; 
    var fileData = await provider.Files[i].ReadAsByteArrayAsync(); 
    if (mediaType == MediaType.Thumbnail) 
    { 
     // MediaId is mandatory for Audio & Video media 
     if (String.IsNullOrWhiteSpace(provider.FormData["mediaId"])) 
     // ReSharper disable once NotResolvedInText 
      return ErrorResponse(new ArgumentNullException("mediaId", "MediaId was not provided")); 
     itemId = new Guid(provider.FormData["mediaId"]); 
     await blobHelper.Upload(mediaType, accountId, itemId, fileData, timelineEvent.ChildId); 
     var mediaItem = timelineEvent.Media.Single(m => m.Id == itemId); 
     mediaItem.HasThumbnail = true; 
     mediaItem.LastUpdated = DateTime.UtcNow; 
     await timelineEventRepository.UpdateAsync(timelineEvent, entityDoc.SelfLink); 
    } 
    else 
    { 
     itemId = await blobHelper.Upload(mediaType, accountId, fileData, timelineEvent.ChildId); 
     var mediaItem = new TimelineMediaItem 
     { 
      Id = itemId, 
      Available = true, 
      FileSize = fileData.Length, 
      Removed = false, 
      Type = mediaType.ToUpper(), 
      TaggedChildren = new List<TaggedChild>(), 
      Created = DateTime.UtcNow, 
      LastUpdated = DateTime.UtcNow 
     }; 
     if (fileLengthsRequired) 
      mediaItem.Length = fileLengths[i]; 
     timelineEvent.Media.Add(mediaItem); 
     await timelineEventRepository.UpdateAsync(timelineEvent, entityDoc.SelfLink); 
    } 
    response.MediaIds.Add(itemId); 
} 

Erklärung für DocumentClient:

public DocumentRepository() 
{ 
    Client = new DocumentClient(new Uri(ConfigurationManager.AppSettings["DocumentDbEndpointUrl"]), ConfigurationManager.AppSettings["DocumentDbAuthKey"]); 
    DatabaseName = ConfigurationManager.AppSettings["DocumentDbDatabaseName"]; 
    PageSize = Int16.Parse(ConfigurationManager.AppSettings["DefaultPageSize"]); 
    var _database = ReadOrCreateDatabase(); 
    var collection = InitialiseCollection(_database.SelfLink, EntityName); 
    DocumentsLink = collection.DocumentsLink; 
    SelfLink = collection.SelfLink; 
}

danken Ihnen im Voraus.

Je nach Ihrem Problem ging ich davon aus, dass nach bestimmten Nummern des API-Aufrufs Verbindungsprobleme zwischen Ihrem Client- und Documentdb-Endpunkt bestehen. Sie könnten versuchen, eine statische Instanz DocumentClient und fügen Sie die Wiederholungspolitik Ihre DocumentRepository Klasse zu erstellen, wie folgt:

public class DocumentRepository 
{ 
    private static readonly DocumentClient _client; 
    static DocumentRepository() 
    { 
     var connectionPolicy = new ConnectionPolicy 
     { 
      RetryOptions = new RetryOptions() 
      { 
       MaxRetryAttemptsOnThrottledRequests = 5, 
       MaxRetryWaitTimeInSeconds = 5 
      } 
     }; 
     _client = new DocumentClient(
      new Uri(ConfigurationManager.AppSettings["DocumentDbEndpointUrl"]), 
      ConfigurationManager.AppSettings["DocumentDbAuthKey"], 
      connectionPolicy); 
    } 

    public DocumentRepository() 
    { 
     DatabaseName = ConfigurationManager.AppSettings["DocumentDbDatabaseName"]; 
     PageSize = Int16.Parse(ConfigurationManager.AppSettings["DefaultPageSize"]); 
     var _database = ReadOrCreateDatabase(); 
     var collection = InitialiseCollection(_database.SelfLink, EntityName); 
     DocumentsLink = collection.DocumentsLink; 
     SelfLink = collection.SelfLink; 
    } 

    public async Task UpdateAsync(TimelineEvent timelineEvent, string selfLink) 
    { 
     //TODO: 
     await _client.UpsertDocumentAsync("{documentCollectionUri}", timelineEvent); 
    } 
}
