我有一个使用ZendSOAP在PHP中创建的web服务,其URL如下：
mysite.net/webservice/wsdl. WSDL定义如下：
<?xml version="1.0"?>
<deFinitions xmlns="http://schemas.xmlsoap.org/wsdl/" xmlns:tns="mysite.net/webservice" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap-enc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" name="Soap" targetNamespace="mysite.net/webservice">
<types>

</types>
<portType name="SoapPort">
<operation name="cancelTrans">
<documentation>Return cancel payment status</documentation>
<input message="tns:cancelTransIn" />

当我尝试使用ColdFusion将数据发送到Web服务时,我收到以下错误：

ErrNumber 0
ExceptionMessage Content is not allowed in prolog.

我的ColdFusion代码如下：
<cfinvoke
method="cancelTrans"
returnvariable="rawXMLPaymentStatus"
webservice="mysite.net/webservice/wsdl">
<cfinvokeargument name="token" value="ABCDEFG">
<cfinvokeargument name="transAmount" value="30.15">
<cfinvokeargument name="transDate" value="20170208">
<cfinvokeargument name="transId" value="123456">
</cfinvoke>
<cfset status = XmlParse(rawXMLPaymentStatus)>
<cfdump var="#status#">
有什么帮助吗？
谢谢.
解决方法:
(来自评论……)
An error occurred while Parsing an XML document
更新：然后响应不是您所期望的(即无效的xml).转储响应变量以查看它实际包含的内容,< cfdump var =“#rawXMLPaymentStatus#”>
与错误无关,但您可能希望使用createObject()来使用Web服务.它与cfinvoke的功能相同,但语法更紧凑：
<!--- create the web service instance --->
<cfset ws = createObject("webservice", "http://example.com/webservice/wsdl")>
<!--- invoke the cancelTrans method with appropriate arguments --->
<cfset result = ws.cancelTrans("ABCDEFG", "30.15", "20170208", "123456")>
<!--- display results --->
<cfdump var="#result#">
I get the following error: An error occurred while executing the
application. Please try again or contact the administrator.
听起来你启用了自定义错误处理,因此应用程序显示的是通用消息,而不是真正的错误.假设这是您的DEV环境,请暂时禁用它.否则,将很难进行故障排除,因为您将无法看到真正的错误消息.如果失败,请将代码块包装在cftry/cfcatch中.转储catch子句中的错误并编辑您的问题以包含完整的错误消息. Trycf.com Example.
