使用ASP.NET的PHP SOAP WebService

<?xml version="1.0" encoding="UTF-8" ?>
<definitions name="MyServices"

        <complexType name="ServiceType">
            <all>
                <element name="id" type="xsd:int" minOccurs="1" maxOccurs="1" />

      <soap:body use="encoded" namespace="urn:my:services" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" />
    </output>
  </operation>
</binding>

<service name="MyServices">
  <port name="ServicesPort" binding="tns:ServicesBinding">
    <soap:address location="http://mydomain.com/api/soap/v11/services"/>
  </port>
</service>
</definitions>

我可以在Visual Studio中从此WSDL成功生成代理类,但在尝试调用getServices方法时,我遇到了异常：

System.Web.Services.Protocols.SoapHeaderException：过程’字符串’不存在

在SOAP服务器端检查原始发布数据后,我的PHP SOAP客户端正在发出如下请求：

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" 
    xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" 
    SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
    <SOAP-ENV:Body>
        <postcode xsi:type="xsd:string">ln4 4nq</postcode>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

而.Net代理类正在执行此操作：

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" 
    xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" 
    xmlns:tns="http://mydomain.com/api/soap/v11/services" 
    xmlns:types="http://mydomain.com/api/soap/v11/services/encodedTypes" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <soap:Body soap:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
        <xsd:string xsi:type="xsd:string">LN4 4NQ</xsd:string>
    </soap:Body>
</soap:Envelope>

我只能假设邮政编码参数发送方式的不同之处在于问题所在,但主要是PHP开发人员,我不知道这里发生了什么.我有一种感觉,我只是遗漏了一些在我的WSDL中至关重要的东西,因为我看过无数的“使用.Net消费PHP SOAP Web服务”的例子,似乎表明它“只是有效”.

关于我在哪里滑倒的任何建议将不胜感激.我现在已经花了差不多一整天了;-)
