容器映像的預設主控台記錄器格式設定

  • 發行項

aspnet 容器中設定的主控台預設格式器已經改變。

先前的行為

在先前的 .NET 6 服務版本中，aspnet 容器映像將 Logging__Console__FormatterName 環境變數設定為 Json。 這造成主控台輸出格式類似於下列所示：

{"EventId":0,"LogLevel":"Information","Category":"Microsoft.Hosting.Lifetime","Message":"Now listening on: http://localhost:7000/","State":{"Message":"Now listening on: http://localhost:7000/","address":"http://localhost:7000/","{OriginalFormat}":"Now listening on: {address}"}}
{"EventId":0,"LogLevel":"Information","Category":"Microsoft.Hosting.Lifetime","Message":"Now listening on: http://localhost:7001/","State":{"Message":"Now listening on: http://localhost:7001/","address":"http://localhost:7001/","{OriginalFormat}":"Now listening on: {address}"}}
{"EventId":0,"LogLevel":"Information","Category":"Microsoft.Hosting.Lifetime","Message":"Now listening on: http://localhost:7002/","State":{"Message":"Now listening on: http://localhost:7002/","address":"http://localhost:7002/","{OriginalFormat}":"Now listening on: {address}"}}
{"EventId":0,"LogLevel":"Information","Category":"Microsoft.Hosting.Lifetime","Message":"Application started. Press Ctrl\u002BC to shut down.","State":{"Message":"Application started. Press Ctrl\u002BC to shut down.","{OriginalFormat}":"Application started. Press Ctrl\u002BC to shut down."}}
{"EventId":0,"LogLevel":"Information","Category":"Microsoft.Hosting.Lifetime","Message":"Hosting environment: Development","State":{"Message":"Hosting environment: Development","envName":"Development","{OriginalFormat}":"Hosting environment: {envName}"}}
{"EventId":0,"LogLevel":"Information","Category":"Microsoft.Hosting.Lifetime","Message":"Content root path: C:\\source\\temp\\web50","State":{"Message":"Content root path: C:\\source\\temp\\web50","contentRoot":"C:\\source\\temp\\web50","{OriginalFormat}":"Content root path: {contentRoot}"}}

新的行為

從 .NET 6.0.5 開始，aspnet 容器映像預設會取消設定 Logging__Console__FormatterName 環境變數。 這會帶來簡單、多行且可由人工判讀的主控台輸出，類似於下列所示：

warn: Microsoft.AspNetCore.Server.HttpSys.MessagePump[37]
      Overriding address(es) ''. Binding to endpoints added to UrlPrefixes instead.
info: Microsoft.Hosting.Lifetime[0]
      Now listening on: http://localhost:7000/
info: Microsoft.Hosting.Lifetime[0]
      Now listening on: http://localhost:7001/
info: Microsoft.Hosting.Lifetime[0]
      Now listening on: http://localhost:7002/
info: Microsoft.Hosting.Lifetime[0]
      Application started. Press Ctrl+C to shut down.
info: Microsoft.Hosting.Lifetime[0]
      Hosting environment: Development
info: Microsoft.Hosting.Lifetime[0]
      Content root path: C:\source\temp\web50

導入的版本

.NET 6.0.5 (2022 年 5 月服務)

中斷性變更的類型

此變更可能會影響來源相容性。

變更原因

隨著 .NET 6 正式發行版本推出而改為使用 JSON 格式，中斷了許多依賴原始單純格式的情節，如 dotnet/dotnet-docker#2725 (英文) 中所述。

如果您想繼續使用 JSON 格式，則可將 Logging__Console__FormatterName 環境變數值設定為 Json，將容器設定為使用 JSON。

受影響的 API

無。
