我創建了一個API(MVC)並將其託管在Azure服務器中。該API一次接收1個圖像和1個文本。對於單個呼叫或第一個呼叫,但在某些API調用獲得低於錯誤之後,它正常工作。Azure服務器在一定數量的API調用後拋出異常

安裝Microsoft.Azure.DocumentDB後:

錯誤:

這裏是我的代碼片段:

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); 
} 

宣言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; 
} 

這是我的錯誤:

您使用的是Azure DocumentDB嗎?我發現了一個關於類似錯誤的問題,你可以參考[it](https://social.msdn.microsoft.com/Forums/en-US/0ddee231-d8f3-451f-8c94-954205ba02fc/azure-documentdb-error -unable到連接到該遠程-serveran-嘗試,是製造到訪問一個插座?論壇= AzureDocumentDB)。你能否提供你的核心代碼片段讓我們找到這個問題? –

@ Bruce-MSFT是的,我正在使用DocumentDB,並使用代碼更新了問題。 –

@ Bruce-MSFT:您有沒有機會檢查上述問題? –

根據您的問題,我認爲在經過一定次數的API調用後,您的客戶端和documentdb端點之間會存在連接問題。你可以嘗試創建的DocumentClient一個靜態實例和重試策略添加到您的DocumentRepository類,如下所示:

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); 
    } 
} 

此外,還有一個官方blog在談論Azure的DocumentDB性能的技巧,你可以參考一下吧。

使用'RetryOptions'時出現錯誤:''ConnectionPolicy'不包含'RetryOptions''的定義 –

我使用了[Microsoft Azure DocumentDB Client Library 1.11.1](https://www.nuget.org/packages /Microsoft.Azure.DocumentDB)在我的開發中,您可以嘗試檢查客戶端庫的版本。任何疑慮,隨時讓我知道。 –

我正在使用'Microsoft.Azure.Documents.Client' –
