asp.net - 如何在 IIS 8 中启用 WebSockets？

Question

我在 Windows 2012、IIS 8 服务器上部署了 SignalR 示例应用程序。

我安装了 WebSocket 协议(protocol)支持，如下所述:http://www.iis.net/learn/get-started/whats-new-in-iis-8/iis-80-websocket-protocol-support

但我仍然无法使用 WebSockets 进行连接。这是我部署的应用程序:http://machines-staging.dgplatformer.net/SignalRSamples/Hubs/HubConnectionAPI/

以及消息日志:

[20:05:12 GMT-0200 (E. South America Daylight Time)]: disconnected => connecting undefined
[20:05:12 GMT-0200 (E. South America Daylight Time)]: connecting => connected 49b8a6d4-41ef-4ff8-8f3d-8e1a513649bb
[20:05:12 GMT-0200 (E. South America Daylight Time)]: 49b8a6d4-41ef-4ff8-8f3d-8e1a513649bb OnConnected
started transport: **serverSentEvents** 49b8a6d4-41ef-4ff8-8f3d-8e1a513649bb

我发现这个部署在 Azure 上(用于比较):http://signalr-test1.cloudapp.net:82/Hubs/HubConnectionAPI/

日志:

20:11:18 GMT-0200 (E. South America Daylight Time) stateChanged: disconnected => connecting
20:11:18 GMT-0200 (E. South America Daylight Time) starting state: connecting
20:11:19 GMT-0200 (E. South America Daylight Time) stateChanged: connecting => connected
20:11:19 GMT-0200 (E. South America Daylight Time) 68b036a9-4e08-49a4-b11c-9ba15718e2d9 OnConnected

要在我们的 IIS8 服务器上使用 WebScokets，我需要做什么？

这是 IIS 日志:

Answer 1

其实我发现问题出在我的办公室网络上，而不是服务器上。我可以使用 3G 网络使用 WebSockets 连接我的智能手机 =)
