Rails POST请求实践融合API

Question

我正在与实践融合API合作接收悬而未决的订单。我正在尝试写一个POST请求，以确认在GET请求期间收到的下载订单。一旦Practice Fusion接收到POST请求，挂起的订单就会被删除。

我用的宝石：

休息-客户

simple_hl7 --用于hl7解析

这是我的工作要求：

def download_pf_orders
  download_count = 0
  uri = "#{PF_TEST_PENDING_API_URL}"
  rest_resource = RestClient::Resource.new(uri, PF_TEST_USERNAME, PF_TEST_PASSWORD)

  begin
    response = rest_resource.get(accept: 'application/json')
    json = JSON.parse(response)

    json.each do |data|

      sequence = data['SequenceNumber']
      puts "### Last Sequence Number: #{sequence}"

      PfOrder.create(
        sequence_number: data['SequenceNumber'],
        message_guid: data['MessageGuid'],
        hl7_document: data['Hl7Document']
        )
      download_count += 1
    end
  rescue => e
    puts "### Status Code: #{e.response.code} ###"
  end
  puts "### Downloaded Orders: #{download_count} ###"
end

下面是Practice Fusion概述的POST请求标准：

示例HL7 ACK消息 给定检索到的带有以下MSH段的订单消息： MSH|^~\&|PracticeFusion|ClientID|||20130930225002+0000||OML^O21^OML_O21|a783a 5d7-c9b2-42e9-abb1-a1b473079512|P|2.5.1|||AL|NE|||||ELINCS_MT-OML-1_1.0 预期的HL7 ACK消息将包含以下MSH和MSA段： MSH|^~\&|PracticeFusion|VendorCode||ClientID|20130930225002+0000||ACK^ELINCS^ ACK_ELINCS|MessageControlID|P|2.5.1||||||||| ELINCS_MT-ACK-1_1.0 MSA\c9b2-42e9-abb1-a1b473079512 *如上面示例顺序和确认消息中的颜色协调所示，您的ACK逻辑应该使用相关订单的MSH-4客户端ID值填充确认的MSH-6客户端ID，使用订单消息的MSH-10中的控制ID填充MSA-2值。 *您确认消息的MSH-4中填充的“供应商代码”值是实践融合指定的唯一值。如果以前没有提供此值，请与您的实现资源联系。

下面是一些提供的C#示例代码来完成这一任务：

/// <summary>
/// Post an HL7 Order Acknowledgement message back to PracticeFusion to signal
acceptance...
/// </summary>
static void AcknowledgeOrder(string hl7AckMessage)
{
  var request = (HttpWebRequest)
  WebRequest.Create(ConfigurationManager.AppSettings["OrderAcknowledgementUri"]);
  request.PreAuthenticate = true;
  request.Credentials = new
  NetworkCredential(ConfigurationManager.AppSettings["PF.ApiUserName"],
   ConfigurationManager.AppSettings["PF.ApiPassword"]);
  request.Method = WebRequestMethods.Http.Post;
  request.ContentType = "application/x-www-form-urlencoded";
  using (var writer = new StreamWriter(request.GetRequestStream()))
  {
   writer.Write(hl7AckMessage);
 }
}

Answer 1

我想出来了。此方法将成功回发，但仍需要考虑如果订单已成功张贴。

def acknowledge_pf_order
  hl7_message = PfOrder.all
  hl7_message.each do |msg|
    clean_msg = msg.hl7_document.gsub(/\r/, '')

    msh_segment = clean_msg.gsub(MSH)
    msh_segment.each do |seg|
      parsed_msh = SimpleHL7::Message.parse(seg)

      parsed_msh.msh[4] = 'yourVendorCode'
      parsed_msh.msh[6] = 'yourClientID'
      parsed_msh.msh[9][1] = 'ACK'
      parsed_msh.msh[9][2] = 'ELINCS'
      parsed_msh.msh[9][3] = 'ACK_ELINCS'
      parsed_msh.msh[21] = 'ELINCS_MT-ACK-1_1.0'

      message_id = parsed_msh.msh[10]
      ack_message = parsed_msh.to_hl7

      msa_segment = "\nMSA|CA|#{message_id.to_s}"

      payload = ack_message << msa_segment

      uri = "#{PF_TEST_ACK_API_URL}"
      rest_resource = RestClient::Resource.new(uri, PF_TEST_USERNAME, PF_TEST_PASSWORD)

      begin
        response = rest_resource.post payload, content_type: 'text/plain'
        puts "### POST Status Code: #{response.code} ###"
      rescue Exception => e
        puts "### POST Status Code: #{e.response.code} ###"
      end
    end
  end
end
