Question

我遇到了一件奇怪的事：我将SOAP请求发送到SOAP服务提供者，SOAP请求信封没有SOAPAction头，并且正文中没有操作名称。但反应仍然可以。这是我的WSDL

请求信封

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:urn="urn:com.tung.switchyard:soap-hello:1.0">
   <soapenv:Header/>
   <soapenv:Body>
      <urn:person>
         <name>John</name><sex>true</sex>
      </urn:person>
   </soapenv:Body>
</soapenv:Envelope>

响应：

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
   <SOAP-ENV:Header xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"/>
   <soap:Body>
      <greetingResponse xmlns="urn:com.tung.switchyard:soap-hello:1.0">
         <response>Hello John</response>
      </greetingResponse>
   </soap:Body>
</soap:Envelope>

在您的WSDL文件中，您已经提到了两个服务的soap action属性，并且这两个服务都具有相同的请求和响应元素。 SOAP Action属性在Http Post Header中发送。当您在没有SOAP Action的情况下发送它时，它将失败。我已经执行了测试，下面是日志。

没有SOAP操作

POST /DemoWS/services/IHello HTTP/1.0
Content-Type: text/xml; charset=utf-8
Accept: application/soap+xml, application/dime, multipart/related, text/*
User-Agent: Axis/1.4
Host: localhost:8080
Cache-Control: no-cache
Pragma: no-cache
SOAPAction: ""
Content-Length: 375

Request Envelope

<?xml version="1.0" encoding="UTF-8"?><soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><soapenv:Body><person xmlns="urn:com.tung.switchyard:soap-hello:1.0"><name xmlns="">Test</name><sex xmlns="">true</sex></person></soapenv:Body></soapenv:Envelope>

Error Response Envelope

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"><soapenv:Body><axis2ns2:Fault xmlns:axis2ns2="http://schemas.xmlsoap.org/soap/envelope/"><faultcode>axis2ns2:Client</faultcode><faultstring>The endpoint reference (EPR) for the Operation not found is http://localhost:8080/DemoWS/services/IHello and the WSA Action = . If this EPR was previously reachable, please contact the server administrator.</faultstring><detail/></axis2ns2:Fault></soapenv:Body></soapenv:Envelope>

使用SOAP Action - 它可以正常运行

POST /DemoWS/services/IHello HTTP/1.0
Content-Type: text/xml; charset=utf-8
Accept: application/soap+xml, application/dime, multipart/related, text/*
User-Agent: Axis/1.4
Host: localhost:8080
Cache-Control: no-cache
Pragma: no-cache
SOAPAction: "NewOperation"
Content-Length: 375

<?xml version="1.0" encoding="UTF-8"?><soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><soapenv:Body><person xmlns="urn:com.tung.switchyard:soap-hello:1.0"><name xmlns="">Test</name><sex xmlns="">true</sex></person></soapenv:Body></soapenv:Envelope>

为什么没有SOAPAction的SOAP请求甚至信封中的操作名称仍然有效？
