无法将“Microsoft.Azure.Devices”包的 azure sdk 日志获取到控制台

Question

我创建了一个示例 .NET 6 控制台应用程序，并添加了以下 Microsoft learn 网站中提到的以下代码行，以启用 azure sdk 客户端库日志。

using AzureEventSourceListener consoleListener =
                                AzureEventSourceListener.CreateConsoleLogger(System.Diagnostics.Tracing.EventLevel.Verbose);

SDK日志

在示例应用程序中，我使用 BlobClient 下载 Blob，该 BlobClient 在“Azure.Storage.Blobs”nuget 包中定义。 我还使用 ServiceClient 发送云到设备消息，该消息在“Microsoft.Azure.Devices”nuget 包中定义。

对于 blob 客户端操作，我可以在控制台中获取 sdk 日志，但对于使用“ServiceClient”的云到设备消息操作，我无法获取 sdk 日志。

附上控制台登录blob操作的sdk日志。

服务客户端操作的类似日志未记录

您能帮我在控制台中获取“Microsoft.Azure.Devices”库的 sdk 日志吗

这是我的代码

using AzureEventSourceListener consoleListener = AzureEventSourceListener.CreateConsoleLogger(System.Diagnostics.Tracing.EventLevel.Verbose); 
var x = new BlobClient(new Uri("BLOB URL")).Download(); 
ServiceClient _serviceClient = ServiceClient.CreateFromConnectionString("CONN STRING"); 
string msg = "Hi Qwerty"; 
Message message = new Message(Encoding.ASCII.GetBytes(msg)); 
await _serviceClient.SendAsync("DEVICE ID", message);

• 使用包 Microsoft.Extensions.Logging 我们可以记录数据 安装

  Microsoft.Extensions.Logging.Console

  Microsoft.Extensions.Logging

• 我能够获取日志

 AzureEventSourceListener consoleListener = AzureEventSourceListener.CreateConsoleLogger(System.Diagnostics.Tracing.EventLevel.Verbose);

 // Set up logger
 var serviceProvider = new ServiceCollection()
     .AddLogging(builder =>
     {
         builder.AddConsole();
     })
     .BuildServiceProvider();

 var logger = serviceProvider.GetService<ILogger<Program>>();

 try
 {
     // Download a blob
     BlobClient blobClient = new BlobClient(new Uri("https://samstoragehello.blob.core.windows.net/hellocont/_ViewImports.cshtml?sp"));
     BlobDownloadInfo downloadedContent = await blobClient.DownloadAsync();

     // Read the downloaded content
     using (var streamReader = new StreamReader(downloadedContent.Content))
     {
         string downloadedContentString = await streamReader.ReadToEndAsync();

         // Send a message to an IoT device
         ServiceClient _serviceClient = ServiceClient.CreateFromConnectionString("HostName=samiothubtodel1.azure-devices.net;SharedAccessKeyName=iothubowner;SharedAccessKey=");
         string msg = "Hi Qwerty";
         Microsoft.Azure.Devices.Message message = new Microsoft.Azure.Devices.Message(Encoding.ASCII.GetBytes(msg));
         await _serviceClient.SendAsync("mywebpi", message);

         // Log information including blob content and IoT message content
         logger.LogInformation("Blob downloaded successfully. Content: {BlobContent}", downloadedContentString);

        
         logger.LogInformation("IoT message sent. Content: {IoTMessageContent}", msg);
     }
 }
 catch (Exception ex)
 {
     // Log error
     logger.LogError(ex, "An error occurred: {ErrorMessage}", ex.Message);
 }

输出：

• 使用此参考文献中的

  Microsoft.Azure.Devices.Client

  MSDOC

   DeviceClient deviceClient = DeviceClient.CreateFromConnectionString(connectionString, TransportType.Mqtt);

 
   deviceClient.SetConnectionStatusChangesHandler((status, reason) =>
   {
       logger.LogInformation($"Connection Status Changed - Status: {status}, Reason: {reason}");
   });

   await deviceClient.OpenAsync();
