Microsoft.AspNet.SignalR實現彈幕(即時通信)

引用

Microsoft.AspNet.SignalR

服務器

自定義Connection

public class BarrageConnection : PersistentConnection { protected override Task OnReceived(IRequest request, string connectionId, string data) { //在這裏能夠作本身的業務處理，好比把彈幕存進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"); } } }

<!--引用Microsoft.AspNet.SignalR後自動添加--> <script src="~/Scripts/jquery.signalR-2.2.2.min.js"></script>

建立鏈接

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

發送消息

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

接收消息

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