HTTP Authorization in SOAP delphi

问题

I am trying to send a request to web service, this is the WSDL: http://www.smsmelli.com/class/sms/webservice/server.php?wsdl

after long researching I underestand untyped array should replace with array of array of string; till here, it solved, but I realize my SOAP doesn't work properly. I check PHP action that works exactly same, then I find it sets Credential in Authentication in the header of HTTP from SOAP;

in WireShark:
-HyperText Transfer Protocol
--Authorization: Basic Y3LIZ577838sdf=
---Credentials: YourUserName:YourPassWord

how can I set that in Delphi 7 with HTTPRIO SOAP?

回答1:

I don't know about Delphi 7, but in XE2 the THTTPRIO has a HTTPWebNode property, which has settings for username and password.

In the BeforePost of the HTTPWebNode you can do detailed manipulation of the HTTP headers, like:

procedure TFrmTestEWS.HTTPRIO1HTTPWebNode1BeforePost(
  const HTTPReqResp: THTTPReqResp; Data: Pointer);
const
   CONTENT_HEADER_EX2010 = 'Content-Type: text/xml; charset=utf-8';
begin
   // http://forum.delphi-treff.de/archive/index.php/t-31817.html
   // Need to exchange the Content-Type Header, because Exchange 2010 expects
   // 'Content-Type: text/xml; charset=utf-8' instead of
   // 'Content-Type: text/xml; charset="utf-8"' which is RFC conform and used by XE2
   HttpAddRequestHeaders(Data, PChar(CONTENT_HEADER_EX2010), Length(CONTENT_HEADER_EX2010), HTTP_ADDREQ_FLAG_REPLACE);
end;

Hope this helps
