SignalR proxy object exception: Uncaught TypeError: Cannot read property & #39; client & #39; of undefined conclusion, signalruncaught

SignalR proxy object exception: Uncaught TypeError: Cannot read property 'client' of undefined conclusion, signalruncaught

So, which is generated by default at the beginning of lower case )... Many people say it's over? NONONO

What do programmers need? Imagination and unconventional imagination!

Then I can imagine whether we can specify a name?

I searched the internet.HubName ("xxx ")You can set the name.

 

By extension, you can set any name, which is not necessarily the same as the class name.

 

So try again?

There are two solutions to this problem: one is to use the lower-case HubName in js, and the other is to specify
