添加新属性的WSDL扩展

Question

我正在做一个与WSDL相关的项目，我想在我的WSDL文件中添加新的属性。WSDL的主要结构是:

<definitions>
<types>
  data type definitions........
</types>
<message>
  definition of the data being communicated....
</message>
<portType>
  set of operations......
</portType>
<binding>
  protocol and data format specification....
</binding>
</definitions>

我想做的是在wsdl中添加服务质量(QoS)属性，所以新的结构是这样的:

<definitions>
<types>
  data type definitions........
</types>
<message>
  definition of the data being communicated....
</message>
<portType>
  set of operations......
</portType>
<binding>
  protocol and data format specification....
</binding>
<QoS>
Qos criteria.....
</QoS>
</definitions>

例如，这个属性将被添加到wsdl:

  <Reliability Qualification="threshold-best-effort" Offered="true">
        <TimeToFailure value= 500000000 unit="sec" source="measured"
        type=”mean” direction=”increasing />
 </Reliability>

结果应该是这样的，<Reliability>属性将被插入到<service>:

<?xml version="1.0" encoding="UTF-8"?>
<wsdl:definitions targetNamespace="http://sample" xmlns:qwsdl="http://example.com/stockquote/schemas"  xmlns:apachesoap="http://xml.apache.org/xml-soap" xmlns:impl="http://sample" xmlns:intf="http://sample" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:wsdlsoap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:http="http://schemas.xmlsoap.org/wsdl/http/" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

         </wsdl:input>
         <wsdl:output name="myCalculationResponse">
            <wsdlsoap:body use="literal"/>
         </wsdl:output>
      </wsdl:operation>
   </wsdl:binding>
   <wsdl:service name="CalculationService">
      <wsdl:port binding="impl:CalculationSoapBinding" name="Calculation">
         <wsdlsoap:address location="http://localhost:8080/Action1/services/Calculation"/>
      </wsdl:port>
   <Reliability Qualification="threshold-best-effort" Offered="true">
    <TimeToFailure value= 500000000 unit="sec" source="measured"
    type=”mean” direction=”increasing />
    </Reliability>
   </wsdl:service>
</wsdl:definitions

我尝试向wsdl添加新的模式，但总是失败。有可能做到吗?知道如何将这个新属性添加到WSDL文件中吗?

Answer 1

WSDL有一个标准定义，您不能像这样自定义它。

根据你的绑定来定义这个模式。

http://www.w3.org/TR/wsdl A4.2

显然，您可以使用这个模式(Ext)

<element name="service" type="wsdl:serviceType"/>
   <complexType name="serviceType">
      <complexContent>
   <extension base="wsdl:documented">
   <sequence>
   <element ref="wsdl:port" minOccurs="0" maxOccurs="unbounded"/>
      <any namespace="##other" minOccurs="0"/>
  </sequence>
      <attribute name="name" type="NCName" use="required"/>
   </extension>
  </complexContent>
  </complexType>

但是我从来没有试过，没有任何样品。
