http調用webservice接口返回錯誤：no SOAPAction header解決方法

錯誤消息：
<?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>
  <soapenv:Fault>
   <faultcode xmlns:ns1="http://xml.apache.org/axis/">ns1:Client.NoSOAPAction</faultcode>
   <faultstring>no SOAPAction header!</faultstring>
   <detail>
    <ns2:hostname xmlns:ns2="http://xml.apache.org/axis/">host1</ns2:hostname>
   </detail>
  </soapenv:Fault>
 </soapenv:Body>

 

解決方法,
    //HttpURLConnection連接，需設置 SOAPAction Header ：
    connect.setRequestProperty("SOAPAction","");//參數2可以是任意字符串,我寫的url
    
        //SOAPAction正確值，應該查看：url.wsdl 的：<soap:operation soapAction="..." />

SOAP和WSDL對Web Service、WCF進行深入瞭解的基礎
