Coldfusion在PHP中使用SOAP Web服务

Question

我有一个使用ZendSOAP在PHP中创建的webservice，URL如下： mysite.net/webservice/wsdl。该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> 
     <xsd:schema targetNamespace="mysite.net/webservice" /> 
    </types> 
    <portType name="SoapPort"> 
     <operation name="cancelTrans"> 
      <documentation>Return cancel payment status</documentation> 
      <input message="tns:cancelTransIn" /> 
      <output message="tns:cancelTransOut" /> 
     </operation> 
    </portType> 
    <binding name="SoapBinding" type="tns:SoapPort"> 
     <soap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http" /> 
     <operation name="cancelTrans"> 
      <soap:operation soapAction="mysite.net/webservice#cancelTrans" /> 
      <input> 
       <soap:body use="encoded" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" namespace="mysite.net/webservice" /> 
      </input> 
      <output> 
       <soap:body use="encoded" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" namespace="mysite.net/webservice" /> 
      </output> 
     </operation> 
    </binding> 
    <service name="SoapService"> 
     <port name="SoapPort" binding="tns:SoapBinding"> 
      <soap:address location="mysite.net/webservice" /> 
     </port> 
    </service> 
    <message name="cancelTransIn"> 
     <part name="transId" type="xsd:string" /> 
     <part name="transDate" type="xsd:string" /> 
     <part name="transAmount" type="xsd:string" /> 
     <part name="token" type="xsd:string" /> 
    </message> 
    <message name="cancelTransOut"> 
     <part name="return" type="xsd:string" /> 
    </message> 
</definitions> 

当我尝试使用ColdFusion将数据发送到Web服务，我得到了以下错误：

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#"> 

请帮忙吗？

谢谢。

（从评论...）

An error occurred while Parsing an XML document

更新：然后响应不正是您期望（即不是有效的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，但您可能希望查看使用createObject()来使用Web服务。它做的事情是一样的cfinvoke，但语法是多了几分紧凑：

<!--- 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.

听起来像是你有启用自定义错误处理，所以应用程序是显示一个通用的消息，而不是真正的错误。假设这是你的DEV环境，暂时禁用它。否则，将很难排除故障，因为您无法看到真正的错误消息。否则，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。
