为什么使用 SMTP 时会出现身份验证错误？

Question

每次我运行这个程序时，它第一次运行，但第二次在终端出现此错误：

Traceback (most recent call last):
  File "main.py", line 30, in <module>
    timenow = datetime.now()
  File "main.py", line 27, in temperature
    moApparent = regexApparentTemp.search(str(json_object))
  File "/usr/local/lib/python3.7/dist-packages/gspread/models.py", line 888, in append_row
    return self.spreadsheet.values_append(self.title, params, body)
  File "/usr/local/lib/python3.7/dist-packages/gspread/models.py", line 119, in values_append
    r = self.client.request('post', url, params=params, json=body)
  File "/usr/local/lib/python3.7/dist-packages/gspread/client.py", line 79, in request
    raise APIError(response)
gspread.exceptions.APIError: {
  "error": {
    "code": 401,
    "message": "Request had invalid authentication credentials. Expected OAuth 2 access token, login cookie or other valid authentication credential. See https://developers.google.com/identity/sign-in/web/devconsole-project.",
    "status": "UNAUTHENTICATED"
  }
}

代码是：

import requests, pprint, re, gspread, time
from oauth2client.service_account import ServiceAccountCredentials
from datetime import datetime



def temperature():
    from oauth2client.service_account import ServiceAccountCredentials
    from datetime import datetime
    scope = ['https://spreadsheets.google.com/feeds', 'https://www.googleapis.com/auth/drive']

    credentials = ServiceAccountCredentials.from_json_keyfile_name('Singapore-Weather-84def2be176a.json', scope)

    gc = gspread.authorize(credentials)

    wks = gc.open('Singapore Weather').sheet1
    r = requests.get('https://api.darksky.net/forecast/b02b5107a2c9c27deaa3bc1876bcee81/1.312914,%20103.780257')
    json_object = r.text


    regexCurrentTemp = re.compile(r'"temperature":(\d\d.\d\d)')
    moTemp = regexCurrentTemp.search(str(json_object))
    temperature = moTemp.group(1)

    regexApparentTemp = re.compile(r'"apparentTemperature":(\d\d.\d\d)')
    moApparent = regexApparentTemp.search(str(json_object))
    apparent = moApparent.group(1)

    timenow = datetime.now()
    wks.append_row([str(timenow), temperature, apparent])

while True:
    temperature()
    time.sleep(3597)

我将 autentication 放在循环中的函数内，这样它就可以工作，但它没有。有什么问题？

正如您在 Github googleapis/oauth2client 上看到的那样，已弃用

建议你试试官方Gmail API Python example:

def create_message(sender, to, subject, message_text):
  """Create a message for an email.

  Args:
    sender: Email address of the sender.
    to: Email address of the receiver.
    subject: The subject of the email message.
    message_text: The text of the email message.

  Returns:
    An object containing a base64url encoded email object.
  """
  message = MIMEText(message_text)
  message['to'] = to
  message['from'] = sender
  message['subject'] = subject
  return {'raw': base64.urlsafe_b64encode(message.as_string(
))}
