小编Utp*_*esh的帖子

我是编程新手，我正在尝试为 .net 核心项目实现日志记录解决方案。

我想收集默认和 Microsoft 类别日志。

APPSETTING.JSON

      {
          "Serilog": {
              "MinimumLevel": {
                  "Default": "Information",
                  "System": "Warning",
                  "Microsoft": "Information"
              },
              "File": {
                  "location": "logs/timeapi.log"
              }
          },
          "EnableSwagger": true
      }

程序.CS

 public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
                WebHost.CreateDefaultBuilder(args)
                    .UseStartup<Startup>()
                    .UseSerilogRequestLogging();

启动文件

app.UseSerilogRequestLogging(options =>
            options.RequestProjection =
            r => new { r.IsHttps, QueryString = r.QueryString.Value });
        app.UseMvc();

https://github.com/mthamil/AspNetCore.Serilog.RequestLoggingMiddleware

我得到的错误是：

Unable to resolve service for type 'Serilog.ILogger' while attempting to activate 'AspNetCore.Serilog.RequestLoggingMiddleware.SerilogRequestMiddleware'.

我将在此处粘贴用于AWS Elastic Loadbalancer的Terraform脚本

    resource "aws_elb" "elb" {
  name = "${var.elb_name}"
  subnets = ["${var.subnet_ids}"]
  internal = "${var.elb_is_internal}"
  security_groups = ["${var.elb_security_group}"]

  listener {
    instance_port = "${var.backend_port}"
    instance_protocol = "${var.backend_protocol}"
    lb_port = 80
    lb_protocol = "http"
  }

  health_check {
    healthy_threshold = 2
    unhealthy_threshold = 2
    timeout = 3
    target = "${var.health_check_target}"
    interval = 30
  }

  cross_zone_load_balancing = true
}

你们可以帮助我使用terraform变量创建多个侦听器吗？
