将client_id和client_secret值更改为您的登录数据，这样就可以了。

import base64
import requests

client_id = 'CLIENT_ID'
client_secret = 'CLIENT_SECRET'
base64_bytes = base64.b64encode(f"{client_id} + ':' + {client_secret}".encode("ascii"))
base64_string = base64_bytes.decode("ascii")

authOptions = {
  'url': 'https://accounts.spotify.com/api/token',
  'headers': {
    'Authorization': 'Basic ' + base64_string,
    'form': {
        'grant_type': 'client_credentials'},
    'json': True}
}

r = requests.post(url = authOptions['url'], data = authOptions['headers'])
assert r.status_code == 200, f"Something went wrong. Status code: {r.status_code}"
token = r.access_token
