在 docker 容器上連接 Azure Sql 服務器數據庫時出現問題

Question

當我在本地運行 web 應用程序時，它可以正常工作，當我在 docker 中運行時，與數據庫的連接給了我這個錯誤：

{ "EventId":20004, "LogLevel":"Error", "Category":"Microsoft.EntityFrameworkCore.Database.Connection", "Message":"使用連接到服務器 'AAAADb' 上的數據庫時發生錯誤 'tcp :aaaaaaaaaa.database.windows.net,1433'.", "State": { "Message":"在服務器 'tcp:aaaaaaaaaa.database.windows.net 上使用數據庫 'AAAADb' 連接時發生錯誤， 1433'.", "database":"AAAADb", "server":"tcp:aaaaaaaaaa.database.windows.net,1433", "{OriginalFormat}":"使用數據庫連接出現錯誤'{數據庫}' 在服務器 '{服務器}'."}}

當我嘗試與 Postman 連接時：

System.InvalidOperationException: An exception has been raised that is likely due to a transient failure. Consider enabling transient error resiliency by adding 'EnableRetryOnFailure' to the 'UseSqlServer' call.

如果我將數據庫更改為 UseInMemoryDatabase，它適用於 Docker。 我還有其他 API 和 Azure 的 MongoDb 並且在雙方都沒有問題。

在此先感謝您的幫助。

Answer 1

Azure SQL 始終需要對所有連接進行加密。 嘗試將以下設置添加到您的連接字符串：

Encrypt=True;TrustServerCertificate=False;

Answer 2

我在其他論壇上看到了解決方案：

這個帖子救了我的命： https://github.com/dotnet/SqlClient/issues/653

我使用這個解決方案並工作。
string ManagedNetworkingAppContextSwitch = "Switch.Microsoft.Data.SqlClient.UseManagedNetworkingOnWindows"; AppContext.SetSwitch(ManagedNetworkingAppContextSwitch, true);
