Question

对于我的Ruby on Rails项目，我正在使用Mail gem通过Net::HTTP::Post::Multipart创建多部分HTTP POST请求。我的HTTP POST请求有一个xml部分，一个smil部分和一个图像部分jpeg。

首先，我使用Nokogiri创建了xml部分：

env_ns = {
    "xmlns:env" => "http://schemas.xmlsoap.org/soap/envelope/"
}

mm7_ns = {
    "xmlns:mm7" => "http://www.3gpp.org/ftp/Specs/archive/23_series/23.140/schema/REL-6-MM7-1-4"
}

builder = Nokogiri::XML::Builder.new do |xml|
  xml['env'].Envelope(env_ns) do
    xml.Header do
      xml['mm7'].TransactionID(mm7_ns, 'xxxx-yyyy-zzzz')
    end
    xml.Body do
      xml.SubmitReq("xmlns" => "http://www.3gpp.org/ftp/Specs/archive/23_series/23.140/schema/REL-6-MM7-1-4") do
        xml.MM7Version(nil, '6.8.0')
        xml.SenderIdentification do
          xml.VASPID(nil, Settings.mms.vasp_id)
          xml.VASID(nil, Settings.mms.vas_id)
          xml.SenderAddress do
            xml.Number(nil, 'XXXXXX')
          end
        end
        xml.Recipients do
          xml.To do
            xml.Number(nil, '+1604XXXXXXX')
          end
        end
        xml.DeliveryReport(nil, false)
        xml.Subject(nil, 'a ruby photo')
        xml.Content({"href"=>'cid:generic_content_id'})
      end
    end
  end
end

然后我使用邮件gem设置请求：

 uri = URI.parse('http://example.com') ##This is not the actual url I'm using. Just for illustration purposes. 
client = Net::HTTP.new(uri.host, uri.port)
mail = Mail.new do
  content_type 'multipart/related; type="text/xml"'
end

然后创建xml部分（在代码中称为soap_part）和smil部分，并将它们添加到请求中：

soap_part = Mail::Part.new do
  content_type 'text/xml; charset="us-ascii"'
  body builder.to_xml
end

smil_part = Mail::Part.new do
  content_type 'application/smil; name=presentation.smil; start=photo'
  content_id 'presentation'
  content_disposition 'attachment; filename=presentation.smil'
  body '<smil xmlns="http://www.w3.org/2001/SMIL20/Language"><head><layout></layout></head><body><seq><img src="cid:photo"/></seq></body></smil>'
end

mail.add_part(soap_part)
mail.add_part(smil_part)

然后我将照片添加为附件：

mail.add_file('script/photo.jpg')
mail.parts.last.content_id = 'photo'

最后，我在设置了一些参数之后发送了请求：

http_headers = {"Content-Type" => 'multipart/related'}
mail.header.fields.each do |field|
  http_headers[field.name] = field.to_s
end

uri = URI(url)

request = Net::HTTP::Post::Multipart.new(uri, http_headers)
request["Content-Type"] ="multipart/related; boundary=#{mail.body.boundary}"
request.body = mail.body.encoded
response = client.request(request)
puts response.body

使用wireshark，捕获的请求类似于：

Accept-Encoding: gzip;q=1.0,deflate;q=0.6,identity;q=0.3
Accept: */*

我从服务器获得的响应是：

<?xml version='1.0' encoding='UTF-8'?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance" xmlns:xsd="http://www.w3.org/1999/XMLSchema">

<faultcode>SOAP-ENV:Protocol</faultcode>
<faultstring>Missing content type.</faultstring>
<faultactor>/xiam-soap/servlet/messagerouter</faultactor>
</SOAP-ENV:Fault>

根据MIME Multipart/Related Content-type

我尝试将request["Content-Type"] ="multipart/related; boundary=#{mail.body.boundary}更改为request["Content-Type"] ="multipart/related; boundary=#{mail.body.boundary}; type=Application/X-FixedRecord"，不确定'Application / X-FixedRecord'会做什么。但是，我仍然遇到完全相同的错误。

该如何解决？谢谢。
