Hello
I am Jos
i have made a program for upload data to mine channels in pytython 2.7, now I am forced to go to 3.9 and I cannot get the program running
code for 2.7
import httplib
import urllib
def WriteData():
while True:
params = urllib.urlencode({'key': 'xxxxxxxxxxxxxxxx', 'field1': '0.021'})
headers = {"Content-typZZe": "application/x-www-form-urlencoded","Accept": "text/plain"}
conn = httplib.HTTPConnection("api.thingspeak.com:80")
try:
conn.request("POST", "/update", params, headers)
response = conn.getresponse()
print (response.status, response.reason)
data = response.read()
conn.close()
except:
print ("connection failed")
break
can someone help me with this code?

Hello Christopher
is there an example for writing multiple channels in python 3.9?
now I can write one channel but I can not find a way for multiple channels
this is the code
baseURL = 'http://api.thingspeak.com/update?api_key=C2MDJO6H1F4JPTG4&field1='
f = urllib.request.urlopen(baseURL +str(cpu_percent))
f.read()
f.close
sleep(0.5)
please help me out
Do you mean multiple channels or multiple fields in the same channel?
For multiple channels, just repeat the call with the appropriate API keys and channel ID's.
For multiple fields, append &fieldx=number to the end of the url.
Hello Christopher
thanks to Ashwin Pajankar I found the right format for multiple fields
baseURL + '&field1=%s&field2=%setc' % (value1, value2,etc)
so I can now write 8 fields

What is the output when you use it in 3.9? What error do you see?
hello Christoper
thanks for your answer.
python 3.9 is using different librarys
so I get a lot of errors.
the question is.
how to use the correct librarys in 3.9
for example
in 3.9 you call http.client in stead of httplib
I got errors about not loading urlibb or errors around urlencode.
so what is the correct code to load same data to thingspeak in 3.9
I have searched internet for the proper code but did not find the correct answer.
I am using thingspeak for a terrarium.
I made a temperature control which data is send into thingspeak
I hope someone can help me with the proper code.
So I can use python 3.9 instead 2.7
