无法启动红隼。 System.FormatException: 无效 URL: 'http:////*:80'

Question

我在发布应用程序后无法启动 dotnet 核心应用程序。 dotnet run 在开发环境中启动应用程序时，尝试在发布后启动应用程序只会引发此错误。

这是我的Program.cs

namespace NiqVive.Api
{
    public class Program
    {
        public static void Main(string[] args)
        {
            CreateWebHostBuilder(args).Build().Run();
        }

        public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
            WebHost.CreateDefaultBuilder(args)
                .UseStartup<Startup>()
                .UseKestrel(options =>
                    {                    
                        options.Listen(IPAddress.Any, 5007);
                        options.Limits.MaxRequestBodySize = null;
                    })

                .UseDefaultServiceProvider(options => {
                    options.ValidateScopes = false;
                });

    }
}

--硬件版本：2.1.401

运行时环境： OS 姓名：ubuntu OS版本：18.04 RID：ubuntu.18.04-x64 基本路径：/usr/share/dotnet/sdk/2.1.401/

如果我发布应用程序，它不会启动。

转到属性文件夹并打开 launchSetting.json 文件更改端口号与其他一些在 "applicationUrl": "http://localhost:5001;http://localhost:4000", here we have http://localhost:5000 将其更改为另一个端口
