我正在使用 SignalR Wiki Getting Started Hubs 页面中的示例聊天应用程序。我已经扩展它以添加组支持,它工作正常。
但是,现在我想从外部控制台应用程序向组发送消息。这是我的控制台应用程序代码,下面是我的组代码。如何从代理向群组发送消息?是否可以?
// Console App
using System;
using Microsoft.AspNet.SignalR.Client.Hubs;
namespace SignalrNetClient
{
class Program
{
static void Main(string[] args)
{
// Connect to the service
var connection = new HubConnection("http://localhost:50116");
var chatHub = connection.CreateHubProxy("Chat");
// Print the message when it comes in
connection.Received += data => Console.WriteLine(data);
// Start the connection
connection.Start().Wait();
chatHub.Invoke("Send", "Hey there!");
string line = null;
while ((line = Console.ReadLine()) != null)
{
// Send a message to the server
connection.Send(line).Wait();
}
}
}
}
SignalR Web 应用程序主机:
namespace SignalrServer.Hubs
{
public class Chat : Hub
{
public void Send(string message)
{
// Call the addMessage method on all clients
Clients.All.addMessage(message);
Clients.Group("RoomA").addMessage("Group Message " + message);
}
//server
public void Join(string groupName)
{
Groups.Add(Context.ConnectionId, groupName);
}
}
}
