urlencode | command line tool for manipulating URL | Command Line Interface library

I am working on an integration into an old API which for some reason returns the json data as a text/html response. I have tried to Deserialse this string using Newtonsoft in C# and also using various javascript libraries including JSON.parse() but all have failed.

The actual response looks like a valid json object but it fails to get deserialised:

{"err":201,"errMsg":"We cannot find your account.\uff01","data":[],"selfChanged":{}}

I am taking it that there are some special characters or that the actual response is in a format that any of my parsers cannot not deserialise out the box. I have attached various code samples in various languages including curl. I would really appreciate if someone could help deserialise the response object in C# or point me in the right direction.

Hi I am trying to create chat app using xamarin app, .net core api and signalR.
I need to get id of curent user inside of SignalR chatHub.
I tried to get HttpContext by using IHttpContextAccessor but SignalR doesn't support it.
I tried to get HttpContext by Context.GetHttpContext() but it only returns empty Context
(as far as i understand to get current HttpContext with Context.GetHttpContext() project either has to be website or i need to place [Authentication] on my ChatHub )

I am using basic authentication on my project and i don't know how to pass user credentials to SignalR hub

Here is code from Xamarin project ChatViewModel which i use to create new connection to Signalr hub(connection without authentication part works fine)
I don't know how to get curent users email and password instead of "email@hotmail.com" and "123"
