Question

对于我的Ruby on Rails项目，我将邮件gem与net/http/和net/http/post/multipart一起使用，以将多部分post http请求发送到外部API，以将MMS消息从Web应用程序发送到手机。

我的多部分http发布请求将包含一个XML部分（是一些XML），一个smil部分（可以为空或空），然后是一个图像部分（例如jpeg图像及其图像字符串）。

首先，对于XML部分，我使用以下命令设置解析器：

wsdl = Rails.root.join('app','services', 'wsdls','mm7.wsdl')
self.xml_parser = Savon.client(wsdl: wsdl.to_s,
                               convert_request_keys_to: :none,
                               log: true, logger: Rails.logger, namespace_identifier: nil)

请注意，我的wsdl仅来自https://markmail.org/download.xqy?id=rnl72qvlptaeylfg&number=3，只是我将其另存为文件。

然后，为了生成多部分的http发布请求，我使用了以下代码：

xml= xml_parser.build_request(:submit_message, message: {
    MM7Version: '6.8.0',
    SenderIdentification: {
        VASPID: Settings.mms.vasp_id,
        VASID: Settings.mms.vas_id,
        SenderAddress:{Number: 'Some number'}
    }, Recipients:{To: {Number: 'Some other number'}}}, soap_header:{
    'mm7:TransactionID': 'some uuid'}, message_tag: 'SubmitReq').body
uri = URI.parse('fakeurl')
client = Net::HTTP.new(uri.host, uri.port)
mail = Mail.new do
  content_type 'multipart/related; type="text/xml"'
end

soap_part = Mail::Part.new do
  content_type 'text/xml; charset="utf-8"'
  body xml
end

other_part = Mail::Part.new do
  content_type 'multipart/related; type="application/smil"'
end

smil_part = Mail::Part.new do
  content_type 'application/smil; charset="utf-8"'
end

#Put the image file here
other_part.add_file('script/ruby.jpg')
other_part.add_part(smil_part)

mail.add_part(soap_part)
mail.add_part(other_part)

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

使用Wireshark，我可以看到我的请求看起来像：

Accept: */*

Host: somehost.org
Content-Type: multipart/form-data; boundary=-----------RubyMultipartPost
Content-Length: 7829

发送请求后，我得到的响应是：

HTTP Status 400 - Error unmarshalling envelope: javax.mail.MessagingException: Missing start boundary

我对应该如何处理起始边界感到困惑。在生成的请求中，我看到诸如boundary=-----------RubyMultipartPost，----==_mimepart_5c7019f236d9e_399610f2f2024937之类的东西，难道不是应该作为界限吗？

谢谢！

Ruby使用邮件gem发送Multipart Http POST请求。缺少起始边界错误
