我正在使用Mail gem发送带有我的应用程序附件的电子邮件。具体来说,我的devbox和服务器机器上有相同的代码,用于报告pdf文件。但是,从我的devbox作为附件发送的pdf在Thunderbird和其他客户端中显示正常,而来自服务器的附件仅在SOME(而不是雷鸟)邮件客户端中显示。我已经打开了电子邮件来源来比较这两者,并尝试深入了解这个问题:

添加附件的简单行(Rails):
email.add_file filename: "sample.pdf", content: File.read("/public/sample.pdf")
关闭蝙蝠,部分标识符不同(_av vs mimepart),并且每个附件编码的方式在几行之后也不同。我的问题是,什么可能导致某些客户不尊重&#34; mimepart&#34;作为附件的部分?除此之外,下一个问题是为什么相同的代码会产生不同的输出,但如果我知道潜在的问题,我可以自己解决。谢谢!
