Web API access

[AndiLübeck]

Hello!
I try to make the Web API access example from your YouTube Video with the esp8266.
https://www.youtube.com/watch?v=8xqgdXvn3yw&t=607s
Want to modify it to work with my OpenWeatherMap account.
Maybe you can help me with this. Thanks in Advance!

Code is attached …. also the Json Output of the OWM

Thanks for giving it a try. Everything looks good, what problems are you having?

[AndiLübeck]

Sorry for my late Response!
As long as i understand the COMport snippet. The ESP8266 gets Connection to the OWM API and get the result of the GET method.

…..but when i am heading to the Website it gives me this….

the >JSON RESPOND FROM OWM SERVER:< from my previous post is the respond when i type direct query to the browser!
Maybe you can Show me how modify the Code to fit to OWM API.
THNX for helping
Andreas

I've been away from this repo for a couple of years. One way to debug these issues is opening the debug tools on modern web browsers, and seeing what the errors on the JS side are. I'd be happy to revisit this issue if you're still having trouble. I'm closing the issue in the meantime, but anyone for anyone stumbling here by way of a search, feel free to re-open as needed.
