PTV API signature generator code - Python 3

ptv_signature.py

from hashlib import sha1
import hmac

def getUrl(request):
    devId = 1000000
    key = bytes('mykey','UTF-8')
    
    request = request + ('&' if ('?' in request) else '?')
    raw = bytes(request+'devid={0}'.format(devId),'UTF-8')
    
    hashed = hmac.new(key, raw, sha1)
    signature = hashed.hexdigest()
    raw = str(raw,'UTF-8')
    return 'http://timetableapi.ptv.vic.gov.au/'+raw+'&signature={1}'.format(devId, signature),'UTF-8'
    
request_url = '/v3/routes'
print(getUrl(request_url))

JFC, thank you.

JFC, thank you.

You are welcome. whats JFC mean?

Jesus Fucking Christ :)

Sorry, PTV’s explanation on how to calculate the signature truly sucked. I wasn’t far off though! Nonetheless, thanks mate, I owe you a beer.

Ah yep, it made literally no sense - leading me to post this here in the off chance others struggled and found it.

Yeah, right. To be honest, I actually almost had it right but was missing a slash from the endpoint. What a crazy way of authenticating tho?! Anywhoo, cheers!

Thanks for this, I was really stuck.
One comment is that you can change line 14 to remove reference to "devID" as you already deal with it in line 9. eg
return 'http://timetableapi.ptv.vic.gov.au'+raw+'&signature={0}'.format(signature)
For me this removes a Type warning.
