ruby-on-rails – 从Rails发送Outlook日历邀请

我已经尝试过互联网上的所有建议,但是无法让它发挥作用.

class Notifications < ActionMailer::Base
  def add_interaction
    @i = i
    ical = Icalendar::Calendar.new
    e = Icalendar::Event.new
    e.start = DateTime.now.utc
    e.start.icalendar_tzid="UTC" # set timezone as "UTC"
    e.end = (DateTime.now + 1.hour).utc
    e.end.icalendar_tzid="UTC"
    e.organizer @i.interviewer_email
    e.created = DateTime.now
    e.uid = e.url = "#{HOSTNAME.to_s+'/interaction/'+@i.id.to_s}"
    e.summary "#{INTERACTION_TYPE[@i.itype][0]} with #{@i.company}"
    e.description <<-EOF
    #{INTERACTION_TYPE[@i.itype][0]} with #{@i.company}
    Date: #{@i.start_time.strftime('%e %b %Y')}
    Time: #{@i.start_time.strftime('%I:%M %p')}
    EOF
    ical.add_event(e)
    ical.custom_property("METHOD","REQUEST")

    email=mail(to: "sample@email.com",subject: "Interview",mime_version: "1.0",content_type:"text/calendar",body:ical.to_ical,content_disposition:"inline; filename=calendar.ics",filename:'calendar.ics')
    email.header=email.header.to_s+'Content-Class:urn: content-classes:calendarmessage'
    return email
  end
end

它被称为

Notifications.add_interaction(Interaction.last).deliver

我也尝试将邮件构造为

email=mail(to: "nikhil@talentauction.in,nikhil@zobtree.com",subject: "#{@i.bid.company.name} has suggested a time for #{INTERACTION_TYPE[@i.itype][0]}",content_type:"multipart/alternative",body:'')
    html_body = render_to_string("/notifications/add_interaction")
    email.add_part(
        Mail::Part.new do
            content_type "text/html"
            body html_body
        end
    )
    p = Mail::Part.new do
        content_type 'text/calendar; method=REQUEST name="calendar.ics"'
        content_disposition "inline; filename=calendar.ics"
        content_transfer_encoding "8bit"
        body ical.to_ical
    end
    p.header=p.header.to_s+'Content-Class:urn: content-classes:calendarmessage'
    email.add_part(p)

但在所有情况下,日历邀请都作为Outlook中的附件提供.

我注意到一些奇怪的事情,这可能是造成这种情况的原因.当我查看电子邮件来源时,在这两种情况下,最顶层的mimetype是multipart / mixed,(第一次代替文本/日历,第二次代替multipart / alternative)

而当从控制台发送电子邮件时,它会这样说

编辑：我使用mandrill发送电子邮件,如果这将有任何帮助
