在.net核心控制台应用程序中创建Websocket服务器 [英] Create a websocket server in .net core console application

问题描述

有什么方法可以创建一个可以托管WebSocket服务器的.NET Core 控制台应用程序吗？

Is there any way to create a .NET Core console application which can host a WebSocket server?

我看到了很多东西

我最终使用的NuGet软件包必须是.NET Core，而不是完整的.NET。

The NuGet package I end up using must be .NET Core and not full .NET.

如果我可以在控制台应用程序中使用 Microsoft.AspNetCore.WebSockets ，我该怎么做？

If I can use Microsoft.AspNetCore.WebSockets in a console application, how would I do it?

推荐答案

自托管的ASP.net Core应用程序实际上是控制台应用程序，使用Kestrel作为服务器，您可以非阻塞地运行它并以常规控制台，像这样：

Self-hosted ASP.net Core applications are in fact console applications, using Kestrel as the server you can run it in non-blocking and continue the program as a regular console one, something like this:

public static void Main(string[] args)
{

    var host = new WebHostBuilder()
        .UseKestrel()
        .Build();                     //Modify the building per your needs

    host.Start();                     //Start server non-blocking

    //Regular console code
    while (true)
    {
        Console.WriteLine(Console.ReadLine());
    }
}

唯一的缺点是您将获得一些调试信息消息开头，但您可以对此进行修改：

The only downside of this is you will get some debug messages at the begining, but you can supress those with this modification:

public static void Main(string[] args)
{

    ConsOut = Console.Out;  //Save the reference to the old out value (The terminal)
    Console.SetOut(new StreamWriter(Stream.Null)); //Remove console output

    var host = new WebHostBuilder()
        .UseKestrel()
        .Build();                     //Modify the building per your needs

    host.Start();                     //Start server non-blocking

    Console.SetOut(ConsOut);          //Restore output

    //Regular console code
    while (true)
    {
        Console.WriteLine(Console.ReadLine());
    }
}
