我有一个ColdFusion 11站点,需要使用SOAP请求与支付处理器进行通信。我已经知道它可以与CFHTTP请求一起正常工作,但是返回值(以SOAP消息形式提供)很难使用。
寻找更好的东西,我遇到了CFINVOKE和webservice属性。看来我正确地调用了webservice方法,但是我认为传递给服务的数据格式不正确。
这是有效的SOAP / CFHTTP请求(“ ...”替换了敏感的实现细节):

这两种策略均返回错误消息:

查看详细信息会发现一个扩展的堆栈跟踪,这是我来自远程服务器的原因,它在跟踪顶部附近包含此消息:

我的最佳猜测是这与传入的数据有关。我还尝试过从args中忽略任何设置为nullValue的参数。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;我还没有找到ColdFusion 11的更好选择。
答案 0 :(得分:1)
返回值(以SOAP消息形式传递)很难使用。
您有一个特定的问题吗?通常,您只是将响应解析为XML并使用结构表示法来访问所需的节点:
<cfset root = xmlParse(httpResponse.fileContent)>
<cfdump var="#root#" label="HttpResponse">
<cfoutput>FaultCode = #root.Envelope.Body.Fault.FaultCode.xmlText#</cfoutput>
通常,这比使用createObject(“ webservice”)容易。您已经遇到了最大的问题,即对Web服务错误进行故障排除可能是一个痛苦的过程;-)。错误消息通常比较模糊,最常见的错误是“找不到带有参数{... some params ...}的Web服务操作SomeMethod。” 。不特别有用。它只说明参数有问题,但没有提供有关哪个参数,哪里有问题或如何解决的任何线索。
当然,您通常可以使事情正常……最终。但是,如果它是复杂的Web服务,则并不总是值得花费时间和精力,这就是为什么通常建议使用cfhttp的原因。
查看详细信息会发现一个扩展的堆栈跟踪,这是我来自远程服务器的原因,它在跟踪顶部附近包含此消息:
Cannot perform web service invocation PreparePaymentv2.
无论如何,如果您仍然想尝试cfinvoke,则参数至少存在三个问题:
并非所有元素都是字符串。因此,当无法将空字符串转换为正确的type
时,使用 nullValue =“” 会导致错误。 ORDERATTRIBUTES
就是这样。由于它是可选的,因此如果您不想传递该键的值,则只需从args
结构中完全忽略它即可。
LINEITEMS
不是数组。这是一个结构,其中包含一个名为“ lineitem”的键,它是一个数组。因此,该值应构造如下:
LINEITEMS.LINEITEM = [ {... lineitem data ... } ]
ORDERATTRIBUTES
也是如此。这是一个包含名为“ field”的键的结构,它是一个结构数组:
ORDERATTRIBUTES.FIELD = [ {...field data ... } ]
如果您想了解有关Web服务内部工作方式的更多信息,则CF的功能基于Axis,该功能使用名为wsdl2java的工具将WSDL转换为Java类。通过保存和查看参数生成的文件,您会发现很多有关参数结构的信息。这就是我找出上述问题的方式。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});
