Hi guys, is there any built-in way (without make a custom Hub), to automatically store QueryString values inside OnlineClient.Properties?

Actually I'm working on a FrontEnd custom app, that use SignalR environment to get notified for a specic events. But I need to know some certain client's metadata, and I'd like to use OnlineClient builtin "Properties" property!

    hi

    What is product framework type (.net framework or .net core)?

    You can override the CreateClientForCurrentConnection method to customize OnlineClient.

    Hi @mailming,

    I'm on .net core version.

    Thanks for your reply! What you suggest, is to make a custom Hub inherting OnlineClientHubBase! It is correct, but is what I don't like to do, because it constraints me to reference my own dll inside Web.Host project to map the custom hub.

    I'd like to maintain my customized logic inside a Plugin, and load it dynamically with ABP plugin system!

    My question was if there are any automatic ways to populate OnlineClient.Properties from Querystring!

    If not, I will open a feature request on GitHub, or better, make a PR with this implementation :D

    We can consider adding an IOnlineClientProvider interface to create OnlineClient. Just like the IClientInfoProvider interface. https://github.com/aspnetboilerplate/aspnetboilerplate/blob/37a46288e96a12b5a5318b84fd7bd659b61dc7f4/src/Abp.AspNetCore.SignalR/AspNetCore/SignalR/Hubs/OnlineClientHubBase.cs#L71

    This way you can replace provider through dependency injection.

    You can open PR if you want.
