如何使用python脚本生成访问令牌以列出github api的所有协作者

Question

下面是我的python脚本，用于打印Github存储库的所有协作者。我收到了响应403错误。我不知道我应该在这里使用哪个令牌。它是个人令牌，OAuth令牌。有人可以指导我如何在这里生成访问令牌吗？

# coding: utf-8

import requests
import sys
import json
from pprint import pprint
import codecs

#sys.stdout = codecs.getwriter("utf-8")(sys.stdout)
headers = {'Accept':'application/vnd.github.hellcat-preview+json'}
LIST_REPOSITORIES_API = 'https://api.github.com/repos/d3/d3'
LIST_COLLABORATORS_API = 'https://api.github.com/repos/%s/collaborators'

if __name__ == '__main__':

  headers['Authorization'] = 'token %s' % 'my_token'

  # get repositories
  res = requests.get(LIST_REPOSITORIES_API)
  print(res)
  repos = res.json()

  # get collaborators
  repos2collaborators = []
  collaborators2repos = {}
  print(type(repos))
  print(repos)
  full_name = repos['full_name']
  print(full_name)

  #res1 = requests.get(LIST_COLLABORATORS_API, headers=headers)
  #print(res1)

  res = requests.get(LIST_COLLABORATORS_API % full_name, headers=headers)
  print(res)
