如何将具有SOAP主体的CFHTTP请求转换为CFINVOKE请求

我有一个ColdFusion 11站点，需要使用SOAP请求与支付处理器通信。我已经让它可以很好地处理CFHTTP请求，但是SOAP消息中传递的返回值有点难以处理

为了寻找更好的方法，我遇到了CFINVOKE和webservice属性。看来我正确地调用了webservice方法，但我认为传递给该服务的数据格式不正确

这是正在工作的SOAP/CFHTTP请求。。。替换敏感的实施细节：

查看详细信息会发现一个扩展堆栈跟踪，我认为它来自远程服务器，在跟踪顶部附近包含以下消息：

 Object reference not set to an instance of an object.

编辑：完整的错误详细信息如下所示：

我最好的猜测是这与传入的数据有关。我还尝试从参数中省略设置为nullValue的任何参数。这将导致相同的错误消息。我意识到为nullValue使用空字符串不是最佳选择；对于ColdFusion 11，我还没有找到更好的替代方案

SOAP消息中传递的返回值有点难以处理

你有什么特别的问题吗？通常，您只需将响应解析为XML，并使用结构表示法访问所需的节点：

<cfset root = xmlParse(httpResponse.fileContent)>
<cfdump var="#root#" label="HttpResponse">
<cfoutput>FaultCode = #root.Envelope.Body.Fault.FaultCode.xmlText#</cfoutput>

ORDERATTRIBUTES也是如此。它是一个包含键名字段的结构，这是一个结构数组：

ORDERATTRIBUTES.FIELD = [ {...field data ... } ]

如果您有兴趣了解更多关于web服务如何在内部工作的信息，CF的功能是基于它使用一个名为的工具将WSDL转换为java类。通过保存和查看参数生成的文件，您可以了解参数的结构。这就是我解决上述问题的方法。保存的文件将位于cfusion/stubs子目录中

 // Only need to do this once. DON'T use in Prod as it's very time consuming
 ws = CreateObject("webservice","https://example.com/ServiceWeb.wsdl"
     , {saveJava=true, refreshWSDL=true});

---

你能发布完整的错误信息和跟踪吗？而且我不想这么说，但cfinvoke最终可能不会更易于使用。众所周知，在使用复杂的web服务时很难使用它。cfhttp调用的SOAP响应有什么困难？OT，但是看到CF11和支付处理器在一起让我有点畏缩。我只是注意到代码错误地传递了参数。您需要使用argumentCollection。i、 e.对于createObject调用，请使用ws.PreparePaymentv2argumentCollection=args.@Ageax使用argumentCollection作为指定的结果，错误为：找不到参数为{LOCALREFID={1}、ZIP={}、UNIQUETRANSID={1}、…}的Web服务操作PreparePaymentv2。这实际上是一件好事。web服务现在正在运行，但错误意味着参数与示例不匹配。。。以某种方式参数的类型、数量或格式已关闭。不幸的是，这就是CF给你的所有提示。。。

 LINEITEMS.LINEITEM = [ {... lineitem data ... } ]

ORDERATTRIBUTES.FIELD = [ {...field data ... } ]

 // Only need to do this once. DON'T use in Prod as it's very time consuming
 ws = CreateObject("webservice","https://example.com/ServiceWeb.wsdl"
     , {saveJava=true, refreshWSDL=true});
