QtSoap向webservice传递结构体或类参数

QtSoapType下面有三种分类：QtSoapArray、QtSoapSimpleType、QtSoapStruct

当WebServive接口中出现类似情况时：

<s:element name="TestComplexPara">
<s:complexType>
<s:sequence>
<s:element minOccurs="1" maxOccurs="1" name="para" type="tns:projPara"/>
<s:element minOccurs="0" maxOccurs="1" name="tokenCode" type="s:string"/>
</s:sequence>
</s:complexType>
</s:element>
<s:complexType name="projPara">
<s:sequence>
<s:element minOccurs="0" maxOccurs="1" name="planSn" type="s:string"/>
<s:element minOccurs="1" maxOccurs="1" name="actualLoads" type="s:double"/>
</s:sequence>
</s:complexType>

这里的参数para，在webservice 服务器端是这样定义的：

  [WebMethod]
        public bool TestComplexPara(projPara para)
        {
            return true;
        }

  public class projPara
    {
        public string planSn;
        public double actualLoads;
    }

这种情况下，QtSoap怎样传递这个参数呢，我是这样处理的：

 QtSoapMessage request;
    QtSoapStruct *paraStruct = new QtSoapStruct(QtSoapQName("para"));
    paraStruct->insert(new QtSoapSimpleType(QtSoapQName("planSn"),"test1"));
    paraStruct->insert(new QtSoapSimpleType(QtSoapQName("actualLoads"),QtSoapType::Double,QVariant(2015.9)));
    request.addMethodArgument(paraStruct);
