带有内联附件和非内联附件的HTML-Email

概述使用内联附件和非内联附件创建HTML电子邮件的正确方法是什么？ 另外,请告诉我仅使用内联附件和仅使用非内联附件的内容类型. 直到现在我这样做： MIME-Version: 1.0[some more headers]Content-type: multipart/mixed; boundary="myboundary"--myboundaryContent-Type: text/html 使用内联附件和非内联附件创建HTML电子邮件的正确方法是什么？

另外,请告诉我仅使用内联附件和仅使用非内联附件的内容类型.

直到现在我这样做：

MIME-Version: 1.0[some more @R_403_5548@s]Content-type: multipart/mixed; boundary="myboundary"--myboundaryContent-Type: text/HTML; charset=iso-8859-15Content-transfer-encoding: 7bit[HTML with img cID:my_image]--myboundaryContent-Type: image/png; name="my_image.png"Content-transfer-encoding: base64Content-ID: <my_image>Content-disposition: inline; filename="my_image.png"[base64 image data]--myboundaryContent-type:application/pdf;     name="my_pdf.pdf"Content-length:1150Content-transfer-encoding: base64Content-ID: <my_pdf.pdf>Content-disposition: attachment; filename="my_pdf.pdf"[base64 pdf data]--myboundary--

邮件看起来很好看.但是我注意到Thunderbird没有显示我的内嵌图像,而是显示了2个附件(我的图像和我的pdf).所以我做了一些调试,发现内联图像应该通过Content-Type：multipart / related来发送.

所以我改变了Content-Type：multipart / mixed to Content-Type：multipart / related,Thunderbird显示正确：图像以HTML和一个附件显示,显示pdf.

如果这是正确的解决方案我虽然看似有效,但我并不感到害羞.是否正确使用multipart / related(如果我有内联和非内联附件,如果我只有内联附件,以防万一我只有非内联附件)？

或者是使用一个类型边界相关的拆分内联附件和另一个类型混合边界以拆分非内联附件的正确方法？

我希望你能为我提供样品

解决方法 图片

是的,使用多部分/相关内容类型是正确的方法.以下是一个示例(请注意’Content-Type’和’Content-disposition’值)：
