另一种解决方案是使用主机。Json在项目的根目录中。

{
  "urls": "http://localhost:60000"
}

然后在program。cs中

public static void Main(string[] args)
{
    var config = new ConfigurationBuilder()
        .SetBasePath(Directory.GetCurrentDirectory())
        .AddJsonFile("hosting.json", true)
        .Build();

    var host = new WebHostBuilder()
        .UseKestrel(options => options.AddServerHeader = false)
        .UseConfiguration(config)
        .UseContentRoot(Directory.GetCurrentDirectory())
        .UseIISIntegration()
        .UseStartup<Startup>()
        .Build();

    host.Run();
}

当托管在docker容器(linux版本的我)，你可能会得到一个'连接拒绝'消息。在这种情况下，您可以使用IP地址0.0.0.0，这意味着“这台机器上的所有IP地址”，而不是localhost环回来修复端口转发。

public class Program
{
    public static void Main(string[] args)
    {
        var host = new WebHostBuilder()
            .UseKestrel()
            .UseContentRoot(Directory.GetCurrentDirectory())
            .UseIISIntegration()
            .UseStartup<Startup>()
            .UseUrls("http://0.0.0.0:5000/")
            .Build();

        host.Run();
    }
}

我用以下方法修复了Net core 3.1中的端口问题

在Program.cs中

public class Program
{
    public static void Main(string[] args)
    {
        CreateHostBuilder(args).Build().Run();
    }

    public static IHostBuilder CreateHostBuilder(string[] args) => Host.CreateDefaultBuilder(args)
        .ConfigureWebHost(x => x.UseUrls("https://localhost:4000", "http://localhost:4001"))
        .ConfigureWebHostDefaults(webBuilder => { webBuilder.UseStartup<Startup>(); });
}

您可以使用

http://localhost:4000

https://localhost:4001

如果使用dotnet运行

dotnet run --urls="http://localhost:5001"

在。net Core 3.1上，只需遵循微软的文档，它非常简单:kestrel-aspnetcore-3.1

总结:

Add the below ConfigureServices section to CreateDefaultBuilder on Program.cs: // using Microsoft.Extensions.DependencyInjection; public static IHostBuilder CreateHostBuilder(string[] args) => Host.CreateDefaultBuilder(args) .ConfigureServices((context, services) => { services.Configure<KestrelServerOptions>( context.Configuration.GetSection("Kestrel")); }) .ConfigureWebHostDefaults(webBuilder => { webBuilder.UseStartup<Startup>(); }); Add the below basic config to appsettings.json file (more config options on Microsoft article): "Kestrel": { "EndPoints": { "Http": { "Url": "http://0.0.0.0:5002" } } } Open CMD or Console on your project Publish/Debug/Release binaries folder and run: dotnet YourProject.dll Enjoy exploring your site/api at your http://localhost:5002
