asp.net-core - 从 ASP.NET CORE 中的 appsettings.json 文件读取 Entity Framework 6 连接字符串

Question

我有一个 app.config xml 文件来保存 Entity Framework 的连接字符串，如下例所示:

<configuration>
    <connectionStrings>
        <add name="MyEntities" connectionString="metadata=res://*/EntityFramework.MyEntities.csdl|res://*/EntityFramework.MyEntities.ssdl|res://*/EntityFramework.MyEntities.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=myserver;initial catalog=Example;persist security info=True;user id=myId;password=myPassword;multipleactiveresultsets=false;application name=EntityFramework&quot;" providerName="System.Data.EntityClient" />
    </connectionStrings>
</configuration>

但是我使用的是 ASP.NET Core，我使用环境变量管理多个服务器。所以我需要将此连接字符串保存在我的 appsettings.{enviroment}.json 中，读取此连接并将其设置为属性 Entity Framework 上下文。

我认为您正在寻找类似以下结构的东西。

  "ConnectionStrings": {
    "MyEntities": "metadata=res://*/EntityFramework.MyEntities.csdl|res://*/EntityFramework.MyEntities.ssdl|res://*/EntityFramework.MyEntities.msl;provider=System.Data.SqlClient;provider connection string="data source=myserver;initial catalog=Example;persist security info=True;user id=myId;password=myPassword;multipleactiveresultsets=false;application name=EntityFramework"
  }
