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

# 设置凭据文件路径
creds_file = 'path/to/your/service-account-file.json'

# 加载凭据
creds = service_account.Credentials.from_service_account_file(
    creds_file,
    scopes=['https://www.googleapis.com/auth/business.manage']
)

# 构建API服务
service = build('mybusiness', 'v4', credentials=creds)

# 获取地点列表
def list_locations():
    try:
        locations = service.accounts().list().execute()
        return locations
    except Exception as e:
        print(f"Error: {e}")
        return None

# 在Django视图中使用
from django.http import JsonResponse

def get_locations(request):
    locations = list_locations()
    if locations:
        return JsonResponse(locations)
    else:
        return JsonResponse({'error': 'Failed to retrieve locations'}, status=500)
