Code worked last week - UnicoderEncodeError: 'ascii' codec can't encode characters - Python 3.X

Question

所以，我上周写了这段代码，一切都很好运行。我可以下载该文件，但现在它在尝试发送电子邮件时向我抛出一条错误消息。我环顾四周，似乎找不到任何专门解决此问题的内容。

UnicoderEncodeError：'ascii' 编解码器无法对位置 651-652 中的字符进行编码：序号不在运行de(128)

中

感谢您提供的所有帮助。

Answer 1

encoders.encode_base64(part)

需要在设置payload和header的时候加上。有问题的代码已更正以反映解决方案。
