Python：解析具有嵌入图像的电子邮件 [英] Python: parsing emails with embedded images
问题描述
我正在使用python POP3库连接到邮件服务器的应用程序，解析邮件并将其放入数据库。
我已成功解析文本电子邮件，html电子邮件和附件。现在，我遇到包含电子邮件的嵌入图像的电子邮件。服务器是如何CID：src标签和图像中的图像的一些代码是字节。我不知道如何获取图像并将其与CID进行映射。
请建议。
谢谢以下是我收到的电子邮件内容：

通过检查 Content-Disposition cid的内容。
如果其附件的文件内容应该显示为带有电子邮件的附件，如果其内联内容将显示在正文中。
I am working on an application which connects to the mail server using python POP3 library parses the emails and put them into database.
I have successfully parse the text emails, html emails and attachments. Now, I am stuck with the emails which contain embedded images with the emails. Server is howing CID: some code for the images in the src tag and the image is in the bytes. I am not sure how to get the images and map them with the CIDs.
Please suggest.
Thanks in advance.
below is the email content which I am getting:

Fixed the issue by checking the Content-Disposition value and cid in the contents.
If its attachment the file contents should be shown as attachments with the email and if its inline the contents will be shown in the body.
