使用Gmail API时发生BrokenPipeError

Question

我正在使用Gmail API发送一封带有Python3附件的电子邮件。 我正在尝试与google开发者相同的代码，如下所示：

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

问题是，当附件4.2KB或2.6MB时，代码运行良好；但当附件3.0MB或9.6MB或更大时，会发生错误：

BrokenPipeError: [Errno 32] Broken pipe

有什么问题吗？在

谢谢

似乎在“重试”请求时引发了异常。 我自己还没有遇到过这个错误，但是github上有一个线程在讨论同样的错误。 https://github.com/google/google-api-python-client/issues/218

尝试使用httplib2shim，似乎oauth2client仍然没有被googleauth取代。在

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