Python调用Google MyBusiness API遇UnknownApiNameOrVersion错误求助

核心问题：API名称错误 #

你用的mybusiness这个API名称已经被Google替换，现在Google Business Profile API（原My Business API）对应的正确API标识是mybusinessbusinessinformation（用于位置信息查询）或mybusinessaccountmanagement（用于账户管理操作），而非旧的mybusiness。

具体修正步骤 #

1. 修正API客户端构建代码
   把原来的：

service = build("mybusiness", "v1", credentials=creds)

替换为：

service = build("mybusinessbusinessinformation", "v1", credentials=creds)

2. 修复parent参数的格式错误
   你代码里的parent='accounts/112827745/locations'.format(account_id='myaccount')既没有正确格式化变量，也用错了参数格式——查询位置列表的parent应该是账户ID（格式为accounts/{account_id}），而非accounts/xxx/locations。修正为：

parent = 'accounts/{account_id}'.format(account_id='112827745')
locations = service.accounts().locations().list(parent=parent).execute()

3. 调整凭证校验逻辑顺序
   原来的代码会先调用API再校验凭证有效性，可能导致过期凭证直接报错。调整为优先处理凭证有效性，再执行API调用。

修正后的完整代码 #

from google.cloud import bigquery
from pathlib import Path

from google.auth.transport.requests import Request
from google.oauth2.credentials import Credentials
from google_auth_oauthlib.flow import InstalledAppFlow
from libs.gcp import gcp
import google.auth
from googleapiclient.discovery import build

def run():
    SCOPES = ["https://www.googleapis.com/auth/business.manage"]
    creds = None

    # 加载本地保存的凭证
    if Path("token.json").exists():
        creds = Credentials.from_authorized_user_file("token.json", SCOPES)
    
    # 校验并更新凭证
    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)
        # 保存更新后的凭证
        with open("token.json", "w") as token:
            token.write(creds.to_json())
    
    # 构建API客户端并查询位置
    service = build("mybusinessbusinessinformation", "v1", credentials=creds)
    parent = 'accounts/{account_id}'.format(account_id='112827745')
    locations = service.accounts().locations().list(parent=parent).execute()

    # 打印位置名称
    for location in locations.get('locations', []):
        print(location.get('name'))

为什么Postman能正常调用？ #

Postman里你应该是直接使用了正确的API端点（比如https://mybusinessbusinessinformation.googleapis.com/v1/accounts/{account_id}/locations），而Python的build方法依赖Google的API discovery文档，旧的mybusiness名称已从文档中移除，因此报错。
