Question

我使用Gmail API在Python 3中发送带附件的电子邮件。我尝试使用与Google开发人员相同的代码，如下所示：

https://developers.google.com/gmail/api/guides/sending

问题是当附件 4.2KB 或 2.6MB 时，代码可以正常运行嗯;但是当附件 3.0MB 或 9.6MB 或更大时，会出现错误：

BrokenPipeError: [Errno 32] Broken pipe

这里的问题是什么？

似乎在_retry_request中引发了异常。我自己没有遇到过这个错误，但github上有一个关于同一错误的讨论。 https://github.com/google/google-api-python-client/issues/218

尝试使用httplib2shim，似乎oauth2client仍未被google-auth取代。

我发现的另一个建议是对超过10 MB的文件使用MEDIA / upload选项。有关如何使用/上传的文档：https://developers.google.com/gmail/api/v1/reference/users/messages/send

使用Gmail API时出现BrokenPipeError
