JSON library help

[gquiring]

I am trying to parse this string from WeatherBit.io and I can't get the values from the Deserialization. My other weather JSON strings from another service work, it's just the string from Weatherbit.io that I can't figure out.

DeserializationError error = deserializeJson(doc, line);

tempM = doc["data"]["app_temp"];
wind_speed = doc["data"]["wind_spd"];
wind_dir = convert_windir((doc["data"]["wind_dir"]));
humiM = doc["data"]["rh"];
weatherCode = doc["data"]["weather"]["code"];

{"count":1,"data":[{"app_temp":78.1,"aqi":56,"city_name":"Huntington Farms","clouds":12,"country_code":"US","datetime":"2024-04-29:22","dewpt":60.5,"dhi":83.9,"dni":714.51,"elev_angle":24.27,"ghi":371.1,"gust":11.6,"h_angle":64.3,"lat":33.02,"lon":-80.21,"ob_time":"2024-04-29 22:25","pod":"d","precip":0,"pres":1014,"rh":55,"slp":1016.6716,"snow":0,"solar_rad":370.9,"sources":["rtma","radar","satellite"],"state_code":"SC","station":"G3674","sunrise":"10:33","sunset":"00:02","temp":78,"timezone":"America/New_York","ts":1714429502,"uv":2.3754683,"vis":9.3,"weather":{"description":"Few clouds","code":801,"icon":"c02d"},"wind_cdir":"S","wind_cdir_full":"south","wind_dir":170,"wind_spd":9.4}]}

It should be doc["data"][0]["app_temp"], same for other fields.

That works! I'm confused though, I ran the JSON string through Arduino Json Assistant it does not show the zero. Neither does Chrome when you select Pretty Print.

It's because elements enclosed between square brakets ([ ... ]) indicates an array (collection of elements).
So you have to specify which element in that collection you want to address by specifying its index number.
