邮件中的附件不正确 [英] attachment is not proper in mail in rails

问题描述

我发送邮件附件（1.pdf），但在邮件中它不显示1.pdf，而是显示一些名为ATT008220.dat的随机文件。

i'm sending a mail with attachment(1.pdf) but in mail it doesnt shows 1.pdf instead it shows some random file named "ATT008220.dat".

我正在使用Rails 3.0
以下是我使用的代码：

i'm using Rails 3.0 following is the code i'm using:

        @file = File.read('c:/1.pdf')
        @file.force_encoding('BINARY')
        attachment "application/octet-stream" do |a|
            a.body = @file
        end

有人知道为什么会发生吗？任何想法？

anybody knows why its happening? any idea?

谢谢&问候，

恶劣的Raval。

邮件发送方式：

:---- The mail sending method:

def contact(recipient, subject, message, sent_at = Time.now)   
    @subject = subject
    @recipients = recipient
    @from = '[e-mail]'
    @sent_on = sent_at
    @body = message
    #@file = File.read('c:/1.pdf')
    #@file.force_encoding('US_ASCII')
    #attachment "multipart/alternative" do |a|
    #   a.body = @file
    #end
    attachments['1.pdf'] =  {:mime_type => 'application/pdf',:content => File.read('c:/1.pdf')}
    @headers = {}
end

推荐答案

我有一个类似的问题，试图发送邮件与.xlsx文件作为附件。为了使它工作，我不得不做：

I had a similar problem trying to send a mail with an .xlsx file as attachment. To make it work I had to do:

attachments['filename.xlsx'] = {
  :encoding => 'base64',
  :content  => Base64.encode64(File.read(filename))
}
