当我使用 Ruby 1.92 发送 HTML 电子邮件时，某些电子邮件客户端没有显示附件。附件应为 pdf 文件。我可以在 Exchange 服务器上的 Outlook 2010 中看到附件，但在雅虎网络邮件中看不到。
如果我只是禁用 HTML 正文，一切正常。
代码如下:
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!
这是 HTML 源代码:
<html>
<body>

最佳答案
问题出在你身上
Content-Type: multipart/alternative;
当邮件的内容类型为“multipart/alternative”和附件时，某些邮件程序不会更正解析邮件。在这种情况下，您必须使用此结构创建消息:
- 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
