Question

我正在尝试将AWS CloudWatch Logs用作我的ASP.NET Core应用程序上的日志记录目标。我正在使用官方的AWS NuGet软件包AWS.Logger.AspNetCore。

我使用以下策略创建了一个IAM角色，并将其附加到我的EC2实例：

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "logs:CreateLogGroup",
        "logs:CreateLogStream",
        "logs:PutLogEvents",
        "logs:DescribeLogGroups"
      ],
      "Resource": [
        "arn:aws:logs:*:*:*"
      ]
    }
  ]
}

在我的appsettings.json中，添加了以下内容：

{
  "AWS.Logging": {
    "Region": "ap-southeast-2",
    "LogGroup": "<my app>",
    "LogLevel": {
      "Default": "Warning",
      "System": "Warning",
      "Microsoft": "Warning"
    }
  }
}

在我的Startup.cs文件中，我在Configure方法下添加了以下内容：

loggerFactory.AddAWSProvider(this.Configuration.GetAWSLoggingConfigSection());

启动我的应用程序时，出现以下错误：

Application startup exception
System.NullReferenceException: Object reference not set to an instance of an object.
at <My.Application>.Startup.Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory) in <My.Application>/Startup.cs:line 81
End of stack trace from previous location where exception was thrown ---

at Microsoft.AspNetCore.Hosting.Internal.AutoRequestServicesStartupFilter.<>c__DisplayClass0_0.<Configure>b__0(IApplicationBuilder builder)
at Microsoft.AspNetCore.Hosting.Internal.WebHost.BuildApplication()

Startup.cs:81包含：

app.UseMvc(routes =>
{
   routes.MapRoute(
     name: "default",
     template: "{controller=Home}/{action=Index}/{id?}");
});

我能够使用AWS CLI成功执行EC2实例内的所有CloudWatch Logs操作。

库AWS.Logger.AspNetCore是否需要更多权限？
