sql-server - docker 中的 Asp.net core 未处理的异常。 SqlException (0x80131904) : . .，但是随后在登录前握手期间发生错误

Question

我收到错误

“未处理的异常。Microsoft.Data.SqlClient.SqlException (0x80131904):已成功与服务器建立连接，但在登录前握手期间发生错误。(提供程序:TCP 提供程序，错误:0 - 未知错误 203)"

当我在 ubuntu 19.10 上的 gitlab(自托管)运行程序中使用 docker-compose 在 CI/CD 流中启动 asp.net core 应用程序容器时，所有 docker 镜像 - 最新。

MSSQL 启动后，我可以正常使用 SSMS 连接到它，但应用程序失败并出现异常。

appsettings.json

{
  "ConnectionStrings": {
    "DefaultConnection": "Server=db,34433;Database=master;User Id=sa;Password=password;MultipleActiveResultSets=true"
  },
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft": "Warning",
      "Microsoft.Hosting.Lifetime": "Information"
    }
  },
  "AllowedHosts": "*"
}

知道这里可能出了什么问题吗？

Answer 1

尝试将其附加到 appsettings.json 中的连接字符串:

Integrated Security=false;TrustServerCertificate=true

这样你的配置是:

    "DefaultConnection": "Server=db,34433;Database=master;User Id=sa;Password=password;MultipleActiveResultSets=true;Integrated Security=false;TrustServerCertificate=true"

并在 Dockerfile 中使用 aspnet:3.1-bionic

FROM mcr.microsoft.com/dotnet/aspnet:3.1-bionic
