如何在google登录后获得联系

import google.auth
from google.auth.transport.requests import Request
from google.oauth2 import id_token
from googleapiclient.discovery import build

# 获取用户的访问令牌
def get_access_token():
    credentials, project = google.auth.default()
    if credentials.expired:
        credentials.refresh(Request())
    return credentials.token

# 使用访问令牌调用Google Contacts API
def get_contacts():
    access_token = get_access_token()
    service = build('people', 'v1', credentials=access_token)
    results = service.people().connections().list(resourceName='people/me', personFields='names,emailAddresses').execute()
    contacts = results.get('connections', [])
    return contacts

# 示例代码中的调用
contacts = get_contacts()
for contact in contacts:
    name = contact['names'][0]['displayName']
    email = contact['emailAddresses'][0]['value']
    print(f"Name: {name}, Email: {email}")
