soap1.1与soap1.2区别
soap1.1 request:

POST /WSShakespeare.asmx HTTP/1.1Host: www.xmlme.com Content-Type: text/xml; charset=utf-8Content-Length: length SOAPAction: "http://xmlme.com/WebServices/GetSpeech" <?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>     <GetSpeech xmlns="http://xmlme.com/WebServices">       <Request>string</Request>     </GetSpeech>   </soap:Body> </soap:Envelope>

soap1.2 request:
POST /WSShakespeare.asmx HTTP/1.1Host: www.xmlme.com Content-Type: application/soap+xml; charset=utf-8Content-Length: length  <?xml version="1.0" encoding="utf-8"?> <soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xmlns:xsd="http://www.w3.org/2001/XMLSchema"  xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">   <soap12:Body>     <GetSpeech xmlns="http://xmlme.com/WebServices">       <Request>string</Request>     </GetSpeech>   </soap12:Body> </soap12:Envelope>
I see 3 differences:

SOAP 1.2 uses “application/soap+xml” as Content-Type and SOAP 1.1 uses “text/xml”.
SOAP 1.2 does not use SOAPAction header line.
SOAP 1.2 uses “http://www.w3.org/2003/05/soap-envelope” as the envolope namespace and SOAP 1.1 uses “http://schemas.xmlsoap.org/soap/envelope/
