SOAP message - Add authentication in http header

问题

I have to send a SOAP message to a WebService that needs basic authentication in the http request, but I can't find a way to do it.

After searching I found some solutions and workarounds, but none of them worked.

Here's my code:

procedure TMyForm.HTTPRIOHTTPWebNode1BeforePost(
 const HTTPReqResp: THTTPReqResp; Data: Pointer);
var
 UserName: string;
 PassWord: string;
begin

UserName := 'aaa';
Password := 'bbb';

if not InternetSetOption(Data,
                  INTERNET_OPTION_USERNAME,
                  PChar(UserName),
                  Length(UserName)) then
 raise Exception(SysErrorMessage(GetLastError));

if not InternetSetOption(Data,
                  INTERNET_OPTION_PASSWORD,
                  PChar(Password),
                  Length(Password)) then
 raise Exception(SysErrorMessage(GetLastError));


end;

I tried setting the username and password in the HTTPRIO.HTTPWebNode, but it ignores them, and it doesn't rise the exceptions. The webservice keeps telling me that credentials are missing.

I managed to do it in c#

protected override WebRequest GetWebRequest(Uri uri)
{

    HttpWebRequest request = (HttpWebRequest)base.GetWebRequest(uri);
    Byte[] credentialBuffer = new UTF8Encoding().GetBytes("aaa:bbb");
    request.Headers.Add("Authorization", string.Format("Basic {0}", Convert.ToBase64String(credentialBuffer)));
    return request;

}

but I can't find a way to do it in delphi.

Am I missing something or I'm doing it wrong?

I use DelphiXE8 with Firemonkey.

Ok I did it thanks to the comments.

procedure TMyForm.HTTPRIOHTTPWebNode1BeforePost(
 const HTTPReqResp: THTTPReqResp; Data: Pointer);
var
 auth: String;
begin

  auth := 'Authorization: Basic ' + idEncoderMIME1.EncodeString('aaa:bbb' );
  HttpAddRequestHeaders(Data, PChar(auth), Length(auth), HTTP_ADDREQ_FLAG_ADD);

end;

I just add to the header 'Authorization: Basic ' + username:password encoded.

Actually I only did what I was doing in c#, but I couldn't figure it out before.

Thanks

In newer version of Delphi (before 10.3 Rio)

procedure TClientSOAP.DoHTTPWebNodeBeforePost(
  const HTTPReqResp: THTTPReqResp; Data: Pointer);
var
  auth: String;
begin
  auth := 'Authorization: Basic ' + TNetEncoding.Base64.Encode(FUserName + ':' + FPassword);
  HttpAddRequestHeaders(Data, PChar(auth), Length(auth), HTTP_ADDREQ_FLAG_ADD);
end;

With 10.3 Rio you have to use mjn42 answer even if you have proxy

For HTTP Basic Authentication, this code (placed before calling the SOAP service) should work:

HTTPRIO.HTTPWebNode.UserName := 'aaa';
HTTPRIO.HTTPWebNode.Password := 'bbb';

instead of the TMyForm.HTTPRIOHTTPWebNode1BeforePost event handler
