托管404错误的.Net核心3站点

Question

我有一个.Net核心3网站，我正在尝试托管。我已经成功地部署了一个站点，并试图部署第二个站点，但没有运气。如果我将工作站点的文件夹指向新的站点文件夹，并且还共享了工作站点的应用程序池，它就会工作，所以我百分之百确定这是IIS配置问题。当我尝试浏览时，我得到了404个错误。新站点的唯一不同之处在于它在不同的端口上，并且没有安装证书，因此可能我启动时的SSL代码会产生影响

public class Startup
{

    private string path = string.Empty;
    private string connection = string.Empty;

    public class ErrorDetails
    {
        public int StatusCode { get; set; }
        public string Message { get; set; }
        public override string ToString()
        {
            return JsonConvert.SerializeObject(this);
        }
    }

    public Startup(IConfiguration configuration)
    {
        Configuration = configuration;
    }

    public IConfiguration Configuration { get; }

    // This method gets called by the runtime. Use this method to add services to the container.
    public void ConfigureServices(IServiceCollection services)

            options.HttpsPort = 443;
        });

        //services.AddResponseCaching();
        services.AddMvc(option => option.EnableEndpointRouting = false).AddJsonOptions(options => {

                    Serilog.Log.Error($" Web API error in controller:{routeWhereExceptionOccurred}" + Environment.NewLine + exceptionThatOccurred.ToString() + Environment.NewLine + new String('-', 100));

                    await context.Response.WriteAsync(new ErrorDetails()

                }

            });
        });
    }
}

据我所知，services.AddHttpsRedirection方法将强制http请求重定向到https。

但是如果你没有在IIS服务器上绑定https，那就意味着没有https url，所以它将返回404错误。

要解决此问题，我建议您可以删除此方法，如果您不想为web应用程序启用https。
