可能在文档的<HEAD>中缺少此行:
Probably missing this line in the <HEAD> of your document:
<script src="/signalr/hubs" type="text/javascript"></script>
检查您是否也有
<script src="/Scripts/jquery.signalR-1.0.0.js"></script>
然后使用Fiddler或Chrome开发者工具检查两个文件是否都已加载，并且/hubs文件是否包含您希望集线器定义包含的内容.
And check, using Fiddler or Chrome Developer Tools that both files are loading and that the /hubs file contains what you expect it to contain in terms of hub definitions.
