Google people api，如何访问字段FileAS

from google.oauth2 import service_account
from googleapiclient.discovery import build

# 使用您的OAuth 2.0凭据进行身份验证
credentials = service_account.Credentials.from_service_account_file(
    'path/to/your/credentials.json',
    scopes=['https://www.googleapis.com/auth/contacts']
)

# 构建People API的服务对象
service = build('people', 'v1', credentials=credentials)

# 执行API请求，获取联系人信息
results = service.people().connections().list(
    resourceName='people/me',
    personFields='names,fileAses'
).execute()

# 处理API响应
connections = results.get('connections', [])
for person in connections:
    names = person.get('names', [])
    fileAses = person.get('fileAses', [])
    if names and fileAses:
        print('Name:', names[0].get('displayName'))
        print('FileAs:', fileAses[0].get('value'))
