问题
I have built a simple Chat application using SignalR followed the tutorial there, which works great.
Then I followed the tutorial of SignalR Scaleout with Azure Service Bus, also from Microsoft.
So I have completed all the following steps:
- Created a new Cloud Service on Azure Portal
- Created a new Service Bus namespace on Azure Portal
- Created a Windows Azure Cloud Service with a SignalR ASP.NET Web Role
- Setup the SignalR Web Role running on 2 instances (VM Size: Small)
- Deployed the Cloud Service to the Azure Cloud Service.
But I can't get the SignalR Chat application to work. Can't start the hub.
I noticed it tried to use longPolling and shows status Cancelled/Abort in the browser's debugging tool (Chrome) with the following error in the console:
WebSocket connection to 'ws://example.cloudapp.net/signalr/connect?transport=webSockets&clientProtocol=1.5&connectionToken=KOlz9psd6yCqvYjmCbI3ch5mrXcP%2BAAl3JVMFaP24p2Cv%2FyRb94D5uE27SO9Bz%2B5Itba4vADtv3%2Btv2FMF9LJI6Zxr026UJYxDPNQMVpFTw2hiHd&connectionData=%5B%7B%22name%22%3A%22schathub%22%7D%5D&tid=10' failed: Error during WebSocket handshake: Unexpected response code: 400
and this is the log in the Network:
Do I need to do anything extra besides all the steps listed in the tutorial to make this work?
回答1:
Based on the current Pricing, you need to set the Service bus to at least Standard tier to support Topics.
In this case, I did create my service bus choosing Standard tier, although it shows Standard on it's Overview page under the "Pricing tier" section, I have to specifically go to the settings and scaled it up from Basic to Standard. Which has solved the problem.
