PHP SoapClient __getFunctions() 返回未知类型

Question

我正在尝试构建一个将由 PHP SoapClient 读取的示例 wsdl 文件，尽管我的 wsdl 文档可以正常工作(它正确返回函数)，但仍有一些地方不对，因为 PHP 的 __getFunctions 方法返回以下内容:

array(1) { [0]=> string(35) "UNKNOWN getDocument(UNKNOWN $input)" } 

从这个函数返回的内容来看，类型定义似乎不是 100% 正确的，因为类型显示为 UNKNOWN。

<?xml version="1.0"?>
<definitions name="Document" targetNamespace="urn:Document" xmlns:tns="urn:Document"     xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns="http://schemas.xmlsoap.org/wsdl/"> 
<types>
    <xsd:schema xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="urn:Document">
    <xsd:element name="InputUserType" type="xsd:string" />
    <xsd:element name="DocumentResponseType" type="xsd:string" />         
    </xsd:schema>           
</types>

<message name="getDocumentInputUser">
    <part name="input" type="tns:InputUserType" />
</message> 

<message name="getDocumentResponse">
    <part name="return" type="tns:DocumentResponseType" />
</message>  

<portType name="DocumentPort">
    <operation name="getDocument">
        <input message="tns:getDocumentInputUser" />
        <output message="tns:getDocumentResponse" />
    </operation>
</portType>

<binding name="DocumentBinding" type="tns:DocumentPort">
    <soap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http" />
    <operation name="getDocument">
        <soap:operation soapAction="urn:DocumentAction" />
        <input>
            <soap:body use="encoded" namespace="urn:Document" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" />        
        </input>
        <output>
            <soap:body use="encoded" namespace="urn:Document" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" />        
        </output>
    </operation>      
</binding>

<service name="DocumentService">
    <port name="DocumentPort" binding="tns:DocumentBinding">
        <soap:address location="http://www.apollo.co.za/soap/test2server.php" />
    </port>
</service>

</definitions>

我试图定义一个简单的 wsdl 文档，它有一个操作“getDocument”，它接受一个用户名字符串参数并返回一个字符串结果。我对 SOAP 非常陌生，并且正在努力掌握它，所以如果有人能指出我的 wsdl 定义中的错误，我将不胜感激。

尝试 type='xsd:string' 而不是 type="tns:InputUserType"

希望例子有帮助，这是我使用的一个:

<?xml version='1.0' encoding='UTF-8' ?>
<definitions name='AddWidget'
  targetNamespace='urn:ANYTHINGHEREAddWidget'
  xmlns:tns='urn:ANYTHINGHEREAddWidget'
  xmlns:soap='http://schemas.xmlsoap.org/wsdl/soap/'
  xmlns:xsd='http://www.w3.org/2001/XMLSchema'
  xmlns:soapenc='http://schemas.xmlsoap.org/soap/encoding/'
  xmlns:wsdl='http://schemas.xmlsoap.org/wsdl/'
  xmlns='http://schemas.xmlsoap.org/wsdl/'>

<message name='AddWidgetRequest'>
  <part name='Auth_Username' type='xsd:string'/>
  <part name='Auth_Password' type='xsd:string'/>

</message>
<message name='AddWidgetResponse'>
  <part name='Result' type='xsd:string'/>
</message>

<portType name='AddWidgetPortType'>
  <operation name='AddWidget'>
    <input message='tns:AddWidgetRequest'/>
    <output message='tns:AddWidgetResponse'/>
  </operation>
</portType>

    <input>
      <soap:body use='encoded' namespace='urn:xmethods-delayed-quotes'
        encodingStyle='http://schemas.xmlsoap.org/soap/encoding/'/>
    </input>
    <output>
      <soap:body use='encoded' namespace='urn:xmethods-delayed-quotes'
        encodingStyle='http://schemas.xmlsoap.org/soap/encoding/'/>
    </output>
  </operation>
</binding>

<service name='AddWidgetService'>
