Google cloud platform 通过谷歌应用程序引擎（只读文件系统）访问谷歌搜索控制台api

当我在google应用程序引擎应用程序中使用oauth2client.file.storage.get（）时，它返回IOError（errno.EROFS，“只读文件系统”，filename）。日志堆栈如下所示：

为了访问Google搜索控制台API，我使用以下代码对Google搜索控制台API进行身份验证和访问。我认为这是问题的原因

# Prepare the API service
    from oauth2client.file import Storage

    storage = Storage("webmaster_credentials.dat")
    credentials = storage.locked_get()

    http_auth = httplib2.Http()
    http_auth = credentials.authorize(http_auth)
    service = build('webmasters', 'v3', http=http_auth, cache_discovery=False)

我对此做了一些研究。一些聪明人指出，这是因为谷歌应用程序引擎是只读系统

我的问题是：如何在谷歌应用程序引擎中访问谷歌搜索控制台API，以及如何解决这个问题：IOError（errno.EROFS，“只读文件系统”，filename）。

感谢您的回复或评论。

我自己的问题已经解决了。所以我把我的解决方案贴在这里，希望它能在你读到这篇文章时对你有所帮助

问题是必须刷新凭证文件的短期有效令牌，因此必须将新令牌写入google app engine上的凭证文件

我无法使用以下方法完成此操作：

from oauth2client.file import Storage

storage = Storage("webmaster_credentials.dat")
credentials = storage.locked_get()

相反，使用以下身份验证方法一次性解决了我的问题：p

from oauth2client.client import GoogleCredentials
credentials = GoogleCredentials(access_token=access_token, client_id=client_id, client_secret=client_secret,
                                    refresh_token=refresh_token, token_expiry=token_expiry, token_uri=token_uri, user_agent=user_agent, revoke_uri=revoke_uri)

您只需要使用来自google app engine或其他google API的凭据定义变量

祝你好运，快乐
