python将另一个函数的返回值设置为要在标头中使用的变量

Question

尝试在 submit_documents() 函数的请求中获取令牌作为 auth 标头中的变量，如果它是硬编码的，它可以正常工作；但是我需要从 log_in_as_taxpayer() 函数的返回中获取：

import json

class ETax_Integration(object):
    """docstring for ETax_Integration"""
    def __init__(self, arg):
        super(ETax_Integration, self).__init__()
        self.arg = arg
        

    def log_in_as_taxpayer(self):
        
        client_id='###'
        # print(client_id)
        url = "https://url/connect/token"
        client_secret='###'
        # print(client_secret)
        payload={'grant_type':'client_credentials','client_id':{client_id},'client_secret':{client_secret},'scope':'InvoicingAPI'}
        headers = {
          'Content-Type':'application/x-www-form-urlencoded'
        }

        response = requests.request("POST", url, headers=headers, data=payload, verify=False)
        values=json.loads(response.text)
        # print(values['access_token'])
        # print( response.raise_for_status())
        return (values['access_token'])

    def submit_document(self):
        token=self.log_in_as_taxpayer()
        print(token)
        submit_payload = json.dumps({
          "documents": []
        headers = {
          'Content-Type': 'application/json',
          'Authorization': 'Bearer {token}'
        }
        submit_url = "https://api/link"
        response = requests.request("POST", submit_url, headers=headers, data=submit_payload,verify=False)

        print(response.text)
        print( response.raise_for_status())


test=ETax_Integration(object)
# test.log_in_as_taxpayer()
test.submit_document()

f'Bearer {token}'，注意前面的f。请参阅here 和here 了解更多信息或使用您最喜欢的搜索引擎搜索python f-string ;)
