SOA is an integration solution. SOA is message oriented first.
The Key character of SOA is loosely coupled. SOA is enriched
by creating composite apps.

以上是一段wsdl的片断,其中主要定义了一个Add方法。针对粗体字部分,我们得到以下使用该webservice的soap请求。

POST /WebService1/Service1.asmx HTTP/1.1
Host: localhost
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "http://idior.cnblogs.com/Math/Add"

<?xml version="1.0" encoding="utf-8"?>
<
soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:tns="http://tempuri.org/" xmlns:types="http://tempuri.org/encodedTypes" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <
soap:Body soap:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
    <
tns:Add>
      <
xsi:type="xsd:int">int</
a>
      <
xsi:type="xsd:int">int</
b>
    </
tns:Add>
  </
soap:Body>
</
soap:Envelope>


可以看出在WSDL中定义好的SoapAction被放在了Http的请求头中, 为了调用Add这个WebService中的方法,SOAP包中粗体字部分发出的请求恰恰对应了WSDL中定义的operation的name---Add.

那么对于下面的WSDL文件,我们又该发出怎样的SOAP请求呢?

<wsdl:types>
    
<s:schema elementFormDefault="qualified" targetNamespace="http://tempuri.org/">
      
<s:element name="Add">
        
<s:complexType>
          
<s:sequence>
            
<s:element minOccurs="1" maxOccurs="1" name="a" type="s:int" />
            
<s:element minOccurs="1" maxOccurs="1" name="b" type="s:int" />
          
</s:sequence>
        
</s:complexType>
      
</s:element>
      
<s:element name="AddReponse">
        
<s:complexType>
          
<s:sequence>
            
<s:element minOccurs="1" maxOccurs="1" name="AddOperationResult" type="s:int" />
          
</s:sequence>
        
</s:complexType>
      
</s:element>
    
</s:schema>
  
</wsdl:types>
  
<wsdl:message name="AddOperationSoapIn">
    
<wsdl:part name="parameters" element="tns:Add" />
  
</wsdl:message>
  
<wsdl:message name="AddOperationSoapOut">
    
<wsdl:part name="parameters" element="tns:AddReponse" />
  
</wsdl:message>
  
<wsdl:portType name="MathServiceSoap">
    
<wsdl:operation name="AddOperation">
      
<wsdl:input message="tns:AddOperationSoapIn" />
      
<wsdl:output message="tns:AddOperationSoapOut" />
    
</wsdl:operation>
  
</wsdl:portType>
  
<wsdl:binding name="MathServiceSoap" type="tns:MathServiceSoap">
    
<soap:binding transport="http://schemas.xmlsoap.org/soap/http" style="document" />
    
<wsdl:operation name="AddOperation">
      
<soap:operation soapAction="http://idior.cnblogs.com/Math/Add" style="document" />
      
<wsdl:input>
        
<soap:body use="literal" />
      
</wsdl:input>
      
<wsdl:output>
        
<soap:body use="literal" />
      
</wsdl:output>
    
</wsdl:operation>
  
</wsdl:binding>


现在为了调用AddOperation(注意 Add改成AddOperation了)方法,你认为Soap Body中对应的那个元素名???是什么呢?

POST /WebService1/Service1.asmx HTTP/1.1
Host: localhost
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "http://idior.cnblogs.com/Math/Add"

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  
<soap:Body>
    
<??? xmlns="http://tempuri.org/">
      <a>int</a>
      <b>int</b>
    </???

  
</soap:Body>
</soap:Envelope>
