Microsoft.AspNet.SignalR实现弹幕(即时通讯)

引用

Microsoft.AspNet.SignalR

服务器

自定义Connection

public class BarrageConnection : PersistentConnection
{
    protected override Task OnReceived(IRequest request, string connectionId, string data)
    {
        //在这里可以做自己的业务处理，比如把弹幕存进redis等等
        return Connection.Broadcast(data, connectionId);
    }
}

Map SignalR

[assembly: OwinStartup(typeof(BarrageDemo2.Website.Startup))]
namespace BarrageDemo2.Website
{
    public class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            app.MapSignalR<BarrageConnection>("/barrageConnection");
        }
    }
}

客户端

引用

<!--引用Microsoft.AspNet.SignalR后自动添加-->
<script src="~/Scripts/jquery.signalR-2.2.2.min.js"></script>

创建连接

connection = $.connection("/barrageConnection");

发送消息

connection.send({ userName: userName, comment: comment });

接收消息

connection.received(function (data) {
    var bulletObj = JSON.parse(data);
    //......
});
