html - Rails 邮件程序 mimepart 在邮件正文中显示为文本

Question

我正在使用 ActionMailer 发送测试邮件。正在呈现模板并且邮件正在正常发送。唯一的问题是 mime 部分和其他 header 数据由 Google 在邮件正文中显示。

这是邮件的代码..

def testing

    mail(:to => "apoorvparijat@gmail.com",:subject => "html mailer", :content_type => "text/html") do |format|
          format.html { render 'testing' }
          format.text { render :text => "bing" }
    end
end

这是收到的电子邮件。

Answer 1

不要在邮件方法中指定 :content_type => "text/html"。由于您使用的是格式 block ，因此 Rails 会自动选择 MIME 类型。

更多详情:

试试这个发送多部分电子邮件(即电子邮件的 html 和文本格式)。注意格式的顺序。

mail(:to => "apoorvparijat@gmail.com", :subject => "html mailer") do |format|
    format.text { render :text => "bing" }
    format.html { render 'testing' }
end
