Delphi rest and authentication

Question

I have a web .NET service. I can connect this web service from web browsers. If I write service address first web browser ask username and password than service is connected.

If I connect this web service with delphi . There is error message:

Error message is "401 Unauthorized"

I am using:

• RESTResponse1
• RESTRequest1
• RESTClient1 and HTTPBasicAuthenticator 1.
• HTTPBasicAuthenticator1 has username and password and RestClient add Authenticator.

But I can not connect web service How can I connect it?

Answer 1

To find out the reason for the missing (or wrong) authentication you can use the developer / debug mode in most web browsers. You could also use Wireshark or a HTTP proxy.

Check the response headers of the server. They include information about all supported authentication modes (see RFC 2616 )
