Rails 邮件附件在电子邮件正文中

Question

我需要发送带有附件的简单邮件。现在它发送一封电子邮件，但附件是这样的电子邮件正文。

--
Content-Type: text/csv;
 charset=UTF-8
Content-Transfer-Encoding: 7bit
Content-Disposition: attachment;
 filename=errors_in_address_table.csv
Content-ID: <5b0e7d6b4abff_10c12ac224c8b0d4994d@development.mail>

发送电子邮件的当前代码

saved_file = Rails.root.join('db', 'fix_db', 'errors_in_address_table.csv')
mailer = ActionMailer::Base.mail(from: 'no-replay@test.com', to: 'test@test.com', subject: 'Errors in database', body: '', content_type: 'multipart/mixed')
mailer.attachments['errors_in_address_table.csv'] = { mime_type: 'text/csv', content: File.read(saved_file) }
mailer.deliver

我试图让它正常工作几个小时。也许一些更有经验的程序员可以帮助我。

Answer 1

对于遇到此问题的其他人，这应该可以从 Rails 控制台工作（至少在 Rails 6+ 中）：

mailer = ActionMailer::Base.new
mailer.attachments['errors_in_address_table.csv'] = File.read(saved_file)
mailer.mail(from: 'from@test.com', to: 'to@test.com', subject: 'Errors', body: '').deliver

Answer 2

我的应用中有一些不同的附件代码，我不确定这是否适合您，但您可以尝试一下。

尝试替换你的块

saved_file = Rails.root.join('db', 'fix_db', 'errors_in_address_table.csv')
mailer = ActionMailer::Base.mail(from: 'no-replay@test.com', to: 'test@test.com', subject: 'Errors in database', body: '', content_type: 'multipart/mixed')
mailer.attachments['errors_in_address_table.csv'] = { mime_type: 'text/csv', content: File.read(saved_file) }
mailer.deliver

下面这个比较简单：

attachments['errors_in_address_table.csv'] = open(Rails.root.join('db', 'fix_db', 'errors_in_address_table.csv')).read
mail(from: 'no-replay@test.com', to: 'test@test.com', subject: 'Errors in database', body: '')

这实际上是一种试错法。不行的话我就删了。

你也有你的邮件的看法吗？

根据分享的描述，您似乎需要修改附件代码

saved_file = Rails.root.join('db', 'fix_db', 'errors_in_address_table.csv')
mailer = ActionMailer::Base.mail(from: 'no-replay@test.com', to:    'test@test.com', subject: 'Errors in database', body: '', content_type: 'multipart/mixed')
mailer.attachments['errors_in_address_table.csv'] = saved_file
mailer.deliver
