[开发工具]Asp.net core 使用SignalR推送消息

环境：

.net core3.1

一.服务端配置（Startup）

ConfigureServices

Configure

二、自定义类继承Hub?

public class SignalRHub: Hub
    {
        private readonly IHubContext<SignalRHub> _hubContext = null;

        public SignalRHub(IHubContext<SignalRHub> context)
        {
            _hubContext = context;
        }


        public override Task OnConnectedAsync()
        {
            Console.WriteLine($"{Context.ConnectionId}已连接");
            return base.OnConnectedAsync();
        }


        public void ReadClientMsgMethod(string msg)
        {
            Console.WriteLine($"{ Context.ConnectionId}客户端发来信息：" + msg);

        }

        /// <summary>
        /// 全员发送
        /// </summary>
        /// <param name="msg"></param>
        /// <returns></returns>
        public string CallAllClients(string msg)
        {
            Console.WriteLine("============全员发送==========");
            Clients.All.SendAsync("CallByHub", "全员发送>>>>>>>>>>" + msg);
            return MethodInfo.GetCurrentMethod()?.Name + "";
        }

        //发送消息--发送给所有连接的客户端
        public Task SendMessage(string msg)
        {
            return _hubContext.Clients.All.SendAsync("CallByHub", msg);
        }
    }

每天进步一点！
