Instead of url ="https://api.weatherbit.io/v2.0/current?city"+city+"&key,
make it url ="https://api.weatherbit.io/v2.0/current?city="+city+"&key
Basically, add = after the current?city
Also please never share your API keys publicly on the forum, if shared please re-generate it.
Do let me know if you need any other help.
