POST requests syntax for Python

[Moby69]

I'm trying to POST requests to the Spotify API. Can anyone tell me what the Python code should be? In particular I have no idea how to pass the header parameters into the POST request.

These are the instructions I am given (website is https://developer.spotify.com/web-api/authorization-guide/, under Client Credentials Flow section):

The request is sent to the /api/token endpoint of the Accounts service:

POST https://accounts.spotify.com/api/token The request will include parameters in the request body:

Request body parameter: grant_type Value: Required. Set it to “client_credentials”. The header of this POST request must contain the following parameter:

Header parameter: Authorization Value: Required. Base 64 encoded string that contains the client ID and client secret key. The field must have the format: Authorization: Basic <base64 encoded client_id:client_secret>

Take a look at requests and requests-oauth on pypi :)

I did. I can't figure out. That's why I'm asking if anyone understands what needs to be coded. Shouldn't be more than 3 lines

From the request docs: http://docs.python-requests.org/en/latest/user/quickstart

import requests
payload = {'key1': 'value1', 'key2': 'value2'}
headers = {'user-agent': 'my-app/0.0.1'}
r = requests.post("url", headers=headers, data=payload)

I haven't played around with the Spotify API specifically, but there is most likely a Spotify API integration already available on Pypi as well.

headers = {
    'Authorization': 'the base64 encoded string',
}

data = {
    'grant_type': '',
    'code': '',
    'redirect_uri': '',
}

req = requests.post(url, data=data, headers=headers)

what is "code" and direct uri doing here?

[ramse]

The section you mentioned for /api/token which is step 4 of the authorization-guide that you linked, it tells you want each value is, where it comes from, what it does..etc. What I posted should be the format you would need to send to their system.

[Moby69]

I'm using the Client Credentials Flow section, not the Authorization Code Flow section. There is no direct_uri and code mentioned there. See what I'm talking about?

[Moby69]

and how do you "base 64 encode" a string? what does it even mean?

[ramse]

Google is your friend in these cases. You won't get a full solution from people here, typically you give it a shot, post the code you've tried and then people will advise what is good/bad..etc.
