我的代码：

from Google import Create_Service

from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText

CLIENT_SECRET_FILE = 'client_secret.json'
API_NAME = 'gmail'
API_VERSION = 'v1'
SCOPES = ['https://mail.google.com/']

service = Create_Service(CLIENT_SECRET_FILE, API_NAME, API_VERSION, SCOPES)

任何帮助都将不胜感激。

Answer 1

您应该在项目文件Google.py的文件夹中创建，这里是它的代码

import pickle
import os
from google_auth_oauthlib.flow import Flow, InstalledAppFlow
from googleapiclient.discovery import build
from googleapiclient.http import MediaFileUpload, MediaIoBaseDownload
from google.auth.transport.requests import Request


def Create_Service(client_secret_file, api_name, api_version, *scopes):
print(client_secret_file, api_name, api_version, scopes, sep='-')
CLIENT_SECRET_FILE = client_secret_file
API_SERVICE_NAME = api_name
API_VERSION = api_version
SCOPES = [scope for scope in scopes[0]]
print(SCOPES)

cred = None

pickle_file = f'token_{API_SERVICE_NAME}_{API_VERSION}.pickle'
# print(pickle_file)

if os.path.exists(pickle_file):
    with open(pickle_file, 'rb') as token:
        cred = pickle.load(token)

if not cred or not cred.valid:
    if cred and cred.expired and cred.refresh_token:
        cred.refresh(Request())
    else:
        flow = InstalledAppFlow.from_client_secrets_file(CLIENT_SECRET_FILE, SCOPES)
        cred = flow.run_local_server()

    with open(pickle_file, 'wb') as token:
        pickle.dump(cred, token)

try:
    service = build(API_SERVICE_NAME, API_VERSION, credentials=cred)
    print(API_SERVICE_NAME, 'service created successfully')
    return service
except Exception as e:
    print('Unable to connect.')
    print(e)
    return None

def convert_to_RFC_datetime(year=1900, month=1, day=1, hour=0, minute=0):
dt = datetime.datetime(year, month, day, hour, minute, 0).isoformat() + 'Z'
return dt

隐式相对导入不再支持记录在案

不再有任何隐含的进口机器。

因此，如果Google.py与您粘贴的代码位于同一个目录中，则必须引用它的真实位置明确地说。

from .Google import Create_Service  # Notice the dot (.)

或者也可以是一条绝对的道路。假设这是Django项目，则如下所示：

from my_proj.Google import Create_Service  # This assumes that your file is in my_proj/my_proj/Google.py
