StreetViewPublishServiceClient在调用API之前是否自动刷新访问令牌？

Question

调用street_view_publish_service_client的api时出现以下错误。看来我的令牌已过期......

  

GaxError（RPC失败，由终止的RPC的＆lt; _Rendezvous引起   with（StatusCode.UNAUTHENTICATED，请求具有无效的身份验证   证书。预期的OAuth 2访问令牌，登录cookie或其他   有效的身份验证凭据。看到   https://developers.google.com/identity/sign-in/web/devconsole-project）＆GT;）

在调用StreetViewPublishServiceClient的API之前，是否会自动刷新凭据的访问令牌？如果没有，我该如何刷新访问令牌？ 以下是示例代码。

pip install gapic-google-maps-streetview_publish-v1
pip install google-auth


from google.streetview.publish.v1 import street_view_publish_service_client
import google.oauth2.credentials

def run():
  creds = google.oauth2.credentials.Credentials(
      MY_ACCESS_TOKEN,
      refresh_token=MY_REFRESH_TOKEN,
      token_uri="https://www.googleapis.com/oauth2/v4/token",
      client_id=GOOGLE_CLINET_ID,
      client_secret=GOOGLE_CLIENT_SECRET) 

    client = street_view_publish_service_client.StreetViewPublishServiceClient(
        credentials=creds)

    upload_ref = client.start_upload()
    print upload_ref

这次修改怎么样？

from google.streetview.publish.v1 import street_view_publish_service_client
import google.oauth2.credentials
import google.auth.transport.requests # Added

def run():
    creds = google.oauth2.credentials.Credentials(
        MY_ACCESS_TOKEN,
        refresh_token=MY_REFRESH_TOKEN,
        token_uri="https://www.googleapis.com/oauth2/v4/token",
        client_id=GOOGLE_CLINET_ID,
        client_secret=GOOGLE_CLIENT_SECRET) 

    creds.refresh(google.auth.transport.requests.Request()) # Added
    client = street_view_publish_service_client.StreetViewPublishServiceClient(
        credentials=creds)

    upload_ref = client.start_upload()
    print upload_ref

注意：

• 此修改假设在访问令牌的到期时间结束之前，访问令牌一直在为您的脚本工作。

参考：

• google.auth.transport.requests

如果这对你没用，我很抱歉。
