从python脚本使用google contacts API的简单方法

pip install --upgrade google-api-python-client google-auth-httplib2 google-auth-oauthlib

import os
import pickle
import google.auth
from google.auth.transport.requests import Request
from google_auth_oauthlib.flow import InstalledAppFlow
from googleapiclient.discovery import build

# 定义要访问的Google服务和API版本
SERVICE_NAME = 'people'
API_VERSION = 'v1'

# 定义要访问的范围
SCOPES = ['https://www.googleapis.com/auth/contacts.readonly']

# 定义保存凭据的文件名
TOKEN_FILE = 'token.pickle'

    creds = None
    if os.path.exists(TOKEN_FILE):
        with open(TOKEN_FILE, 'rb') as token:
            creds = pickle.load(token)
    if not creds or not creds.valid:
        if creds and creds.expired and creds.refresh_token:
            creds.refresh(Request())
        else:
            flow = InstalledAppFlow.from_client_secrets_file(
                'credentials.json', SCOPES)
            creds = flow.run_local_server(port=0)
        with open(TOKEN_FILE, 'wb') as token:
            pickle.dump(creds, token)
    return creds

def main():
    # 获取凭据
    credentials = get_credentials()

    # 创建Google服务
