python - 如何使用 Python/Django 在电子邮件中发送内联图像？

Question

这个问题已经存在:

How to send Inline images in Email with Python/Django?

已关闭 9 年前。

我正在尝试使用 Python/Django 发送包含内嵌图像的电子邮件。

Here是显示我是如何做的代码。它仍在开发中。因此，现在要做的就是发送一封虚拟电子邮件，其中嵌入了大黄蜂的图片。

但是，当我在 Gmail 收件箱中收到电子邮件时，我只看到以下基于文本的电子邮件。电子邮件的各个 Mime 部分以文本形式显示在电子邮件的有效负载中。我点击了 Gmail 中的“显示原始内容”按钮，然后剪切并粘贴了下面的整封电子邮件，以便您可以看到我收到的内容。

有人可以建议我在这里做错了什么吗？以及可能的解决方案？

Answer 1

看起来你有:

multipart/related
-> text/html
-> image/jpeg

我过去在发送电子邮件时也遇到过麻烦，因为顶部部分是多部分/相关的。试试这个:

multipart/mixed
-> multipart/related
--> text/html
--> image/jpeg

此外，请确保并按如下方式设置图像的处置:

img.add_header("Content-Disposition", "inline", filename="myimage")
