I implementation this code for the ServerRequest

StringaValore := '10';
ServerEuronet.URL := 'http://www.w3schools.com/webservices/tempconvert.asmx?op=CelsiusToFahrenheit';
ServerEuronet.Method := rmPost;

ServerEuronet.RequestContent.Clear;
ServerEuronet.RequestContent.Add('<?xml version="1.0" encoding="utf-8"?>');
ServerEuronet.RequestContent.Add('<soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="'" name="http://www.w3.org/2003/05/soap-envelope">'">http://www.w3.org/2003/05/soap-envelope">');
ServerEuronet.RequestContent.Add('<soap12:Body>');
ServerEuronet.RequestContent.Add('<CelsiusToFahrenheit xmlns="'" name="http://www.w3schools.com/webservices/">'">http://www.w3schools.com/webservices/">');
ServerEuronet.RequestContent.Add('<Celsius>' + StringaValore + '</Celsius');
ServerEuronet.RequestContent.Add('</CelsiusToFahrenheit>');
ServerEuronet.RequestContent.Add('</soap12:Body>');
ServerEuronet.RequestContent.Add('</soap12:Envelope>');

ServerEuronet.RequestHeaders.Clear;
ServerEuronet.RequestHeaders.Add('POST /webservices/tempconvert.asmx HTTP/1.1');
ServerEuronet.RequestHeaders.Add('Host: www.w3schools.com');
ServerEuronet.RequestHeaders.Add('Content-Type: application/soap+xml; charset=utf-8');
ServerEuronet.RequestHeaders.Add('Content-Length: '+ IntToStr(Length(ServerEuronet.RequestContent.Text)));

ServerEuronet.OnComplete := ServerEuronetComplete;   
ServerEuronet.Execute;


procedure TFormRicaricheP.ServerEuronetComplete(Request: TServerRequest);
begin
if (Request.StatusCode=HTTP_OK) then
Begin
  ShowMessage('Risultato Request : '+Request.ResponseContent.Text);
End
else
raise Exception.Create('Errore Server Euronet : '+Request.StatusText);
end;


the services html page is : http://www.w3schools.com/webservices/tempconvert.asmx?op=CelsiusToFahrenheit

but i result only ERROR why ?

Have you looked at other Soap posts in the forum?

I'd be suspicious of doing the header things yourself. I'd expect only
authentication things would be needed. The host is part of the request
itself I think? And the content type is set with a property.

Also, try things out with PostMan (a Chrome application) and see how
that does it. Using a REST tool to pre-flight my calls and replicate
them has been quite handy for me.

Using the Test section and examining the response header there is no
"Access-Control-Allow-Origin" - therefore this will never work with any
external query as they do not allow it. I assume this is just a sample
page and they want you to host it on YOUR web server.

Otherwise the basic query would be like this - i'm using HTTP POST
version as it's way easier to use than SOAP ones:

ServerRequest1.URL :=
'http://www.w3schools.com/webservices/tempconvert.asmx/CelsiusToFahrenheit';
ServerRequest1.Method := rmPost;
ServerRequest1.RequestHeaders.Clear;
ServerRequest1.RequestHeaders.Add('Content-Type:
application/x-www-form-urlencoded');
ServerRequest1.RequestContent.text := 'Celsius=12';
ServerRequest1.Execute;
