根据 SOAP 1.1 标准，POST XML 来访问 WEBSERVICE ，会非常方便，QT 本身有 XML 的解析工具QDomDocument/ QXmlReader。将 POST 的结果进行处理也是非常方便的。

实际应用的时候，只要更改 URL、SOAPAction 、参数、NameSpace 等必要的元素，即可。

QUrl url(urlLineEdit->text());  
    QHttpRequestHeader header("POST", url.path() );  
    header.setValue("Host", url.host() );  
    header.setContentType("text/xml; charset=utf-8");  
    header.setValue("SOAPAction", ""[http://tempuri.org/HelloWorld][http_tempuri.org_HelloWorld]"");

QString content("<?xml version="1.0" encoding="utf-8"?>"  
                    "<soap:Envelope xmlns:xsi="[http://www.w3.org/2001/XMLSchema-instance][http_www.w3.org_2001_XMLSchema-instance]" xmlns:xsd="[http://www.w3.org/2001/XMLSchema][http_www.w3.org_2001_XMLSchema]" xmlns:soap="[http://schemas.xmlsoap.org/soap/envelope/][http_schemas.xmlsoap.org_soap_envelope]">"  
                    "  <soap:Body>"  
                    "    <HelloWorld xmlns="[http://tempuri.org/">sdafwer</HelloWorld][http_tempuri.org_sdafwer_HelloWorld]>"  
                    "  </soap:Body>"  
                    "</soap:Envelope>"  
                    );  
    //header.setValue("Content-Length", tr("%1").arg(11) );  
    http->setHost( url.host() );

httpRequestAborted = false;  
     httpGetId = http->request( header, content.toUtf8 (), buffer);
