Change the representation of special characters in Gatling script

Question

How can I change the representation of special characters in Gatling? I need to do this in token exchange, for example:

Here is sample response from server

1a0
{"Url":"/signalr","ConnectionToken":"gZlor6itFi4JZqAXzTMmsyy/hWxivJg+BRLbTyUwjPhAJBHpf7f2AzOSlFEFuosoeSqMuwN/d7Fask/lrFTKxzFUHZC8ArveNyOb957Cqss18lNSmwiIFiHixGzzC3YAe5YwTdK0Uvb3WVEUvZ/V7g==","ConnectionId":"1fbdd61e-8186-4312-9a51-986d983e28d4","KeepAliveTimeout":20.0,"DisconnectTimeout":30.0,"ConnectionTimeout":110.0,"TryWebSockets":false,"ProtocolVersion":"1.5","TransportConnectTimeout":5.0,"LongPollDelay":0.0}
0

And token from it

gZlor6itFi4JZqAXzTMmsyy/hWxivJg+BRLbTyUwjPhAJBHpf7f2AzOSlFEFuosoeSqMuwN/d7Fask/lrFTKxzFUHZC8ArveNyOb957Cqss18lNSmwiIFiHixGzzC3YAe5YwTdK0Uvb3WVEUvZ/V7g==

Here is the request, which I captured via Fiddler from web app

GET /signalr/connect?transport=serverSentEvents&clientProtocol=1.5&Authorization=Bearer%20pVfF9mgAIu0Uylr9SFmQh3qA-TmG_fy8T60-f9C4bCFQYzTLbgvzNlBKknWZB_6T3ZaLa7z0bQBmvWILLDr_mXQHzlKr4EvGblzuIoeRrCm_vvL55tA0tDmtSoYhtA_mSxH27eG3jAYsXbDDQqqjmQUEtAQQhB6og_b8m2KQL211R14EXjkebDgiNoxkVKDqVKvatByveAq63RdOEzqd8QLNi72czK8SXtlfDttliSlKOYVypJvvdrhs0RmNM40VJBPZfZWd-Ew_I3cs8XKo9noynvWqm_yX7gDvDxNa_wP1lp3SkbExqlwuaJjtpvj3vKrfzTHm5iLLLCVrNZBOhwCjZiSQH_nrB17DG4_k7vWoJjDE3XX1W_ojuEjz3UNclhN28aRASWOJnoALW0Sr9JqRnQOoj8ncVKLnr-mQXr-XSsxNM1nBeUUihspocbjcvxlJYBiI81zzoyI4RKYeTaRKKjiJDvzq6EzFZ8wY3dnJPEKpSJXU7l0peTnHceld&connectionToken=gZlor6itFi4JZqAXzTMmsyy%2FhWxivJg%2BBRLbTyUwjPhAJBHpf7f2AzOSlFEFuosoeSqMuwN%2Fd7Fask%2FlrFTKxzFUHZC8ArveNyOb957Cqss18lNSmwiIFiHixGzzC3YAe5YwTdK0Uvb3WVEUvZ%2FV7g%3D%3D&connectionData=%5B%7B%22name%22%3A%22livechat%22%7D%5D&tid=10 HTTP/1.1

And the token

gZlor6itFi4JZqAXzTMmsyy%2FhWxivJg%2BBRLbTyUwjPhAJBHpf7f2AzOSlFEFuosoeSqMuwN%2Fd7Fask%2FlrFTKxzFUHZC8ArveNyOb957Cqss18lNSmwiIFiHixGzzC3YAe5YwTdK0Uvb3WVEUvZ%2FV7g%3D%3D

But when I extract all tokens and use them in Gatling, I have tokens with special characters, like here

gZlor6itFi4JZqAXzTMmsyy/hWxivJg+BRLbTyUwjPhAJBHpf7f2AzOSlFEFuosoeSqMuwN/d7Fask/lrFTKxzFUHZC8ArveNyOb957Cqss18lNSmwiIFiHixGzzC3YAe5YwTdK0Uvb3WVEUvZ/V7g==

And server responds with 400 error. My question is, how can I change the representation of this characters? Below my script, if additional info is required, let me know.

Have you tried disableUrlEncoding?

It should be the method you are looking for : Gatling official docs: URL encoding

There is an example here in this Github issue: Doc: non-existing method disableUrlEncoding, which is fixed by now
