Question

当我使用Ruby 1.92发送HTML电子邮件时，某些电子邮件客户端中未显示附件。附件应该是pdf文件。我可以在Exchange 2010上查看Exchange 2010中的附件，但不能在yahoo Web邮件中看到。

如果我只是禁用HTML正文，一切正常。

以下是代码：

require 'mail'

body_text = File.read('body.html')
subject_text = File.read("subject.txt")

Mail.defaults do
    delivery_method :smtp, { :address => "servername", :port => "25", :user_name => "name", :password => "password", :authentication => 'login'}
end

message = Mail.new do
    from ARGV[0]
    to ARGV[1]
    subject subject_text

    # if I comment out this section everything works fine
    html_part do
        content_type 'text/html; charset=UTF-8'
        body body_text
    end

    add_file ARGV[2]
end

message.deliver!

以下是HTML来源：

Answer 1

问题在于你的

Content-Type: multipart/alternative;

当这些邮件的内容类型为“multipart / alternative”和附件时，某些邮件程序无法更正解析邮件。在这种情况下，您必须使用以下结构创建消息：

 - multipart/mixed
  - multipart/alternative
 ...

你可以这样做：

unless mail_attachments.blank?
  mail.part :content_type => "multipart/alternative"  do |p|
    p.text_part = text_part
    p.html_part = html_part
  end
  mail_attachments.each do |file|
    mail.add_file file.local_path
  end
else
  mail.text_part = text_part
  mail.html_part = html_part
end

HTML电子邮件缺少附件
