使用 Savon 在 Ruby on Rails 中调用 SOAP 在信封和主要操作周围变得很奇怪

本文介绍了使用 Savon 在 Ruby on Rails 中调用 SOAP 在信封和主要操作周围变得很奇怪的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

在使用 Savon.rb 的 rails 项目中，我试图进行非常复杂的 SOAP 调用.至少在扩展方面很复杂，Savon 构建者会遇到很多麻烦，所以我决定直接操作 :xml.

In a rails project using Savon.rb I am trying to make a very complex SOAP call. At least complex to the extend that Savon builders are to much trouble so I decided to manipulate the :xml directly.

首先我启动客户端:

@client = Savon.client(
            :endpoint => 'https://testservice.postnl.com/CIF_SB/BarcodeWebService/1_1/BarcodeWebService.svc',
            :wsdl     => 'https://testservice.postnl.com/CIF_SB/BarcodeWebService/1_1/?wsdl')

然后我以以下形式拨打电话:

Then I make the call in the shape of:

@request = @client.build_request(:generate_barcode,
             xml: %Q{ ... see soap call (with ruby interpolation) ... }

我添加了一个格式正确的l Time.now, format: :postnl_api 字符串，其余的仍然是硬编码的.包括消息号.

I add a correctly formatted l Time.now, format: :postnl_api string and the rest is still hard coded. Including the message number.

以下是 Savon 在这种情况下实际进行调用的方式，如使用 @request.body 检索到的.

Following is how the call actually is made by Savon in this case, as retrieved using @request.body.

我的应用程序中的 SOAP 调用

<?xml version="1.0" encoding="UTF-8"?>
<s:Envelope 
  xmlns:xsd="http://www.w3.org/2001/XMLSchema"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns:wsdl="http://tempuri.org/"
  xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
  <s:Header>
    <Action s:mustUnderstand="1" xmlns="http://schemas.microsoft.com/ws/2005/05/addressing/none">http://postnl.nl/cif/services/BarcodeWebService/IBarcodeWebService/GenerateBarcode
    </Action>
    <Security xmlns="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd">
      <UsernameToken>
        <Username>devc_!R4xc8p9</Username>
        <Password>xxxxxxxx</Password>
      </UsernameToken>
    </Security>
  </s:Header>
  <s:Body>
    <wsdl:GenerateBarcode>
      <d6p1:Customer>
        <d6p1:CustomerCode>DEVC</d6p1:CustomerCode>
        <d6p1:CustomerNumber>11223344</d6p1:CustomerNumber>
      </d6p1:Customer>
      <d6p1:Barcode>
        <d6p1:Type>3S</d6p1:Type>
        <d6p1:Range>DEVC</d6p1:Range>
        <d6p1:Serie>1000000-2000000</d6p1:Serie>
      </d6p1:Barcode>
    </wsdl:GenerateBarcode>
  </s:Body>
</s:Envelope>

然后，我看到这个电话在公司的沙盒环境中取得了成功，以下是电话的外观.

Then the following is how a call should look as I've seen this one having success in a sandbox environment of the company.

应有的 SOAP 调用

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
  <s:Header>
    <Action s:mustUnderstand="1" xmlns="http://schemas.microsoft.com/ws/2005/05/addressing/none">http://postnl.nl/cif/services/BarcodeWebService/IBarcodeWebService/GenerateBarcode</Action>

    </Security>

      <d6p1:Message>
        <d6p1:MessageID>5</d6p1:MessageID>
        <d6p1:MessageTimeStamp>28-06-2017 14:15:41</d6p1:MessageTimeStamp>
      </d6p1:Message>
      <d6p1:Customer>
        <d6p1:CustomerCode>DEVC</d6p1:CustomerCode>
        <d6p1:CustomerNumber>11223344</d6p1:CustomerNumber>
      </d6p1:Customer>
      <d6p1:Barcode>
        <d6p1:Type>3S</d6p1:Type>
        <d6p1:Range>DEVC</d6p1:Range>
        <d6p1:Serie>1000000-2000000</d6p1:Serie>
      </d6p1:Barcode>
    </GenerateBarcode>
  </s:Body>
</s:Envelope>

主要的事情似乎是关闭的(这也是使用 Savon builder btw 的情况)是 envelope 的属性和主要操作的 :generate_barcode形状及其属性.我不明白为什么我在 GenerateBarcode 之前得到前缀 wsdl:.

The main thing that seems to be off (and this was also the case using the Savon builder btw) is the envelope's attributes and the main operation's :generate_barcode shape as well as its attributes. I don't get why I get the prefix wsdl: before GenerateBarcode.

我告诉 Savon 使用我的 xml 并完全像那样构建它，但它不起作用.按原样发送我的版本会返回错误 400.

I tell Savon to take my xml and build it exactly like that, but it does not work. Sending my version as-is returns an Error 400.

Using @Chris his answer I was able to make the following call:

推荐答案

好的(已验证)

@client = Savon.client(
             :wsdl                    => 'https://testservice.postnl.com/CIF_SB/BarcodeWebService/1_1/?wsdl',
             :log                     => true,
             :wsse_auth               => ['devc_!R4xc8p9', 'xxx'],
             :pretty_print_xml        => true,
             :convert_request_keys_to => :camelcase,
             :env_namespace           => :s,
             :namespace_identifier    => nil
            )

 message =  {
              "d6p1:Message" => {
                "d6p1:MessageID" =>  "10",
                "d6p1:MessageTimeStamp" => Time.now.strftime("%d-%m-%Y %H:%M:%S")
            },
              "d6p1:Customer" => {
                "d6p1:CustomerCode" => "DEVC",
                "d6p1:CustomerNumber" =>  "11223344"},
                "d6p1:Barcode" => {
                  "d6p1:Type" => "3S",
                  "d6p1:Range" => "DEVC",
                  "d6p1:Serie" => "1000000-2000000" } 
            }


attributes = { "xmlns:d6p1" => "http://postnl.nl/cif/domain/BarcodeWebService/", 
               "xmlns:i" => "http://www.w3.org/2001/XMLSchema-instance", 
               "xmlns" => "http://postnl.nl/cif/services/BarcodeWebService/"}

@client.call(:generate_barcode, :attributes => attributes, 
             :message => message, 
             :soap_header => { "Action" => "http://postnl.nl/cif/services/BarcodeWebService/IBarcodeWebService/GenerateBarcode"})

所以诀窍是添加 :namespace_identifier =>nil 并发送 attributes.设置 namespace_identifier 会从 GenerateBarcode 和属性中删除 wsdl 并在 GenerateBarcode 标签上设置一些命名空间.现在我记得我为什么这么讨厌 SOAP 了 :(

So the trick was adding :namespace_identifier => nil and sending attributes. Setting namespace_identifier removes the wsdl from GenerateBarcode ans attributes sets some namespaces on GenerateBarcode tag. Now I remember why I hate SOAP so much :(
