WSDL 绑定差异

Question

在 AXIS 和 CXF 生成的 WSDL 中，总是定义三个绑定元素。
正如以下描述温度转换服务的示例 WSDL 中所报告的那样：

<wsdl:binding name="ConverterSoap11Binding" type="ns:ConverterPortType">
<soap:binding transport="http://schemas.xmlsoap.org/soap/http" style="document"/>
<wsdl:operation name="celsiusToFarenheit">
<soap:operation soapAction="urn:celsiusToFarenheit" style="document"/>
<wsdl:input>
<soap:body use="literal"/>
</wsdl:input>
<wsdl:output>
<soap:body use="literal"/>
</wsdl:output>
</wsdl:operation>
<wsdl:operation name="farenheitToCelsius">
<soap:operation soapAction="urn:farenheitToCelsius" style="document"/>
<wsdl:input>
<soap:body use="literal"/>
</wsdl:input>
<wsdl:output>
<soap:body use="literal"/>
</wsdl:output>
</wsdl:operation>
</wsdl:binding>
<wsdl:binding name="ConverterSoap12Binding" type="ns:ConverterPortType">
<soap12:binding transport="http://schemas.xmlsoap.org/soap/http" style="document"/>
<wsdl:operation name="celsiusToFarenheit">
<soap12:operation soapAction="urn:celsiusToFarenheit" style="document"/>
<wsdl:input>
<soap12:body use="literal"/>
</wsdl:input>
<wsdl:output>
<soap12:body use="literal"/>
</wsdl:output>
</wsdl:operation>
<wsdl:operation name="farenheitToCelsius">
<soap12:operation soapAction="urn:farenheitToCelsius" style="document"/>
<wsdl:input>
<soap12:body use="literal"/>
</wsdl:input>
<wsdl:output>
<soap12:body use="literal"/>
</wsdl:output>
</wsdl:operation>
</wsdl:binding>
<wsdl:binding name="ConverterHttpBinding" type="ns:ConverterPortType">
<http:binding verb="POST"/>
<wsdl:operation name="celsiusToFarenheit">
<http:operation location="celsiusToFarenheit"/>
<wsdl:input>
<mime:content type="application/xml" part="parameters"/>
</wsdl:input>
<wsdl:output>
<mime:content type="application/xml" part="parameters"/>
</wsdl:output>
</wsdl:operation>
<wsdl:operation name="farenheitToCelsius">
<http:operation location="farenheitToCelsius"/>
<wsdl:input>
<mime:content type="application/xml" part="parameters"/>
</wsdl:input>
<wsdl:output>
<mime:content type="application/xml" part="parameters"/>
</wsdl:output>
</wsdl:operation>
</wsdl:binding>

这三种绑定有什么区别？

Answer 1

先看这张图wsdl structure

绑定：Read

所以可以通过三种方式（消息和传输协议）访问您的网络服务，即

ConverterSoap11Binding（消息协议：SOAP 1.1）

ConverterSoap12Binding（消息协议：SOAP 1.2）

ConverterHttpBinding（消息协议：HTTP POST）

以上所有绑定传输协议都是 HTTP（如您的服务地址）。
