My goal is to connect to the Spotify API using pure Python and I have been able to figure out how to obtain the authorization token given the authorization code but I am unable to get the authorization code itself.
Note: I have not provided the client_id and client_secret for obvious reasons and you can assume that all libraries have been imported.
Once the web browser opens, the authorization code ("code") is displayed as a query parameter in the URL but I am unsure how to go about saving it to a variable. I can't just copy and paste it to a variable as the authorization code constantly changes.
My question is how exactly I would go about retrieving the code query paramter and save it to a variable?
Here is what I have tried so far:
# credentials
client_id = "xxx..."
client_secret = "xxx..."
# urls
redirect_uri = "http://localhost:7777/callback"
auth_url = "https://accounts.spotify.com/authorize?"
token_url = "https://accounts.spotify.com/api/token"
# data scopes
scopes = "user-read-private user-read-email"
# obtains authorization code
payload = {
"client_id": client_id,
"response_type": "code",
"redirect_uri": redirect_uri,
"scope": scopes
}
webbrowser.open(auth_url + urlencode(payload))
code = # NOT SURE HOW TO RETRIEVE CODE
# obtains authorization token
encoded_creds = base64.b64encode(client_id.encode() + b":" + client_secret.encode()).decode('utf-8')
token_headers = {
"Authorization": "Basic " + encoded_creds,
"Content-Type": "application/x-www-form-urlencoded"
}
token_data = {
"grant_type": "authorization_code",
"code": code,
"redirect_uri": redirect_uri
}
r = req.post(token_url, data=token_data, headers=token_headers)
You'll need to extract the code from your callback URL. If authentication is successful, Spotify will make a request to your redirect_uri with the code in the query (e.g http://localhost:7777/callback?code=...).
The easiest way to do that is probably spin up a Flask server (or equivalent) with a GET callback endpoint and grab the code there. Then you can exchange it for the authorization token in the same endpoint if you'd like.
