如何使用Python / Django在电子邮件中发送内联图像？

Question

我尝试使用Python / Django发送包含内嵌图片的电子邮件。

Here是显示我如何做的代码。 它还在开发中。所以现在要做的就是发送一个虚拟的电子邮件，里面嵌着一只大黄蜂的照片。

然而，当我在Gmail收件箱中收到电子邮件时，我只会看到以下基于文字的电子邮件。电子邮件的各种Mime部分显示在电子邮件的有效负载中作为文本。 我点击了＆＃34; Show Original＆＃34; Gmail中的按钮，然后剪切粘贴下面的整个电子邮件，以便您可以看到我得到的内容。

有人可以建议我在这里做错了什么吗？还有一个可能的解决方案吗？

Answer 1

看起来你有：

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

我在过去发送电子邮件时遇到了麻烦，其中顶部是多部分/相关的。试试这个：

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

另外，请确保并在图像上设置处置，如下所示：

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