.net core 根据环境变量区分正式、测试 配置文件

新建测试、正式环境下所用的 配置信息文件

appsettings.Development.json 文件信息：

{
  "Logging": {
    "LogLevel": {
      "Default": "Warning"
    }
  },
  "AllowedHosts": "*",
  "db": {
    "mysql": {
      "conStr": "xxxxxxxxxxxxxxxxx", //测试

      "providerName": "MySql.Data.MySqlClient"
    },

    "redis": {
      "conStr": "xxxxxxxxxxxxxxxxx", //测试

      "dbId": "3"
    }
  },

  "ThOcUrl": "xxxxxxxxxxxxxxxxx", //测试
  "ThSftpInfo": "xxxxxxxxxxxxxxxxx", //测试
  "ThFileUrl": "xxxxxxxxxxxxxxxxx" //测试

}

应用程序期间提供初始化提供服务容器的对象

 public void Configure(IApplicationBuilder app, IHostingEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }
            else
            {

                app.UseExceptionHandler("/Error");
            }
            MyServiceProvider.ServiceProvider = app.ApplicationServices;
        }

执行docker run 之前，设置环境变量

set ASPNETCORE_ENVIRONMENT= Development
