c++ builder 使用indy http调用webservice方法

TIdHTTP *http = new TIdHTTP(NULL);

TStringList *formData = new TStringList();

try{

IdAntiFreeze1->OnlyWhenIdle = false;

formData->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>\

<get_print_templates xmlns=\"http://tempuri.org/\">\

 <ai_id>6598</ai_id>\

</get_print_templates>\

  </soap:Body>\

</soap:Envelope>");

http->Request->CharSet="utf-8";

http->Request->ContentType = "text/xml";

http->Request->CustomHeaders = new TIdHeaderList();

http->Request->CustomHeaders->AddValue("SOAPAction", "http://tempuri.org/get_print_templates");

UnicodeString url = serverRootUrl + "inlineadminsite/common/print/PrintWordWin.asmx";

UnicodeString result = http->Post(url, formData);

return result;

}

__finally{

delete formData;

delete http;

}
