signalr - SignalR 作为 WCF Web 套接字服务

Question

是否可以将 SignalR 作为 WCF websocket 服务的一部分而不是 ASP.net 网站的一部分托管。我知道将消息从 Web 服务推送到 signalR 客户端，但是当从浏览器打开套接字连接时，它是否也可能映射到 Web 服务合同？

Answer 1

您可以自托管 SignalR 服务器：

取自（https://github.com/SignalR/SignalR/wiki/QuickStart-Hubs）：

入门 要开始，请安装以下软件包：

Install-Package Microsoft.Owin.Hosting -pre
Install-Package Microsoft.Owin.Host.HttpListener -pre
Install-Package Microsoft.AspNet.SignalR.Owin -pre

using System;
using Microsoft.AspNet.SignalR;
using Microsoft.Owin.Hosting;
using Owin;

namespace SignalR.Hosting.Self.Samples
{
class Program
{
    static void Main(string[] args)
    {
        string url = "http://172.0.0.01:8080";

        using (WebApplication.Start<Startup>(url))
        {
            Console.WriteLine("Server running on {0}", url);
            Console.ReadLine();
        }
    }
}

class Startup
{
    public void Configuration(IAppBuilder app)
    {
        // This will map out to http://localhost:8080/signalr by default
        // This means a difference in the client connection.

        app.MapHubs();
    }
}

public class MyHub : Hub
{
    public void Send(string message)
    {
        Clients.All.addMessage(message);
    }
}

}

You can host the SignarR hub in any .Net application, like:

public class Program
{
public static void Main(string[] args)
{
    // Connect to the service
    var hubConnection = new HubConnection("http://localhost/mysite");

    // Create a proxy to the chat service
    var chat = hubConnection.CreateProxy("chat");

    // Print the message when it comes in
    chat.On("addMessage", message => Console.WriteLine(message));

    // Start the connection
    hubConnection.Start().Wait();

    string line = null;
    while((line = Console.ReadLine()) != null)
    {
        // Send a message to the server
        chat.Invoke("Send", line).Wait();
    }
}
}

If there any specific reason you want to use WCF? you can write your service as SignarR hub only.
