[SignalR]配置路由

注册路由，在代码如下(SignalR 1.*)：

脚本修改如下：

但是其官方文档解释是：

By default, the route URL which clients will use to connect to your Hub is "/signalr". (Don't confuse this URL with the "/signalr/hubs" URL, which is for the automatically generated JavaScript file. For more information about the generated proxy, see  SignalR Hubs API Guide - JavaScript Client - The generated proxy and what it does for you .)
There might be extraordinary circumstances that make this base URL not usable for SignalR; for example, you have a folder in your project named signalr and you don't want to change the name. In that case, you can change the base URL, as shown in the following examples (replace "/signalr" in the sample code with your desired URL).
