I would like to insert something in my project that allows me to check the weather of a few places, in real time. So I found an API that does that (it is “Open Weather Map”) and that returns data in JSON, XML or HTML.
The only thing I want is to get the data returned by the API and display it into my Ignition project. But I don’t get how I can do it : scripting something in Python ? Or maybe there’s a component that can display an HTML page ? That would be great, as Open Weather Map can return an HTML page with everything I want : I just need to display it in a corner of one of my project windows.
I control my Christmas lights with openweatherdata sun set time. I created this component as an example of how to interact with the api. Most of the code is on the timer. test1_weather_2015-08-10_1038.proj (14.2 KB)
As Nick suggested, using system.net.httpGet will retrieve the information for you. There is also systen.util.jsonDecode that will take the json string and objectify it to a dictionary. After that it’s just mining the dictionary for what you want.
The following code will display information for three cities (Morenci is where I grew up. It’s always good to know my parents aren’t getting a tornado…)
response = system.net.httpGet('http://api.openweathermap.org/data/2.5/group?id=5002495,2643743,1850147&units=metric')
json=system.util.jsonDecode(response)
for city in json['list']:
print city['name']+": ", str(city['main']['temp']), city['weather'][0]['description']
Hi,
Thanks a lot for all your answers, that will help me for sure!
Kyle, I can’t open your project because it seems that my designer version is older than yours. Thank you anyway!
I will try to use these Python functions then
Have a nice day!
