Impliment Basic HTTP Authentication In Delphi XE8 Firemonkey On Android And IOS

Developer Al Mannarino from Embarcadero has published a demo on how to implement basic authentication for HTTP in Delphi XE8 Firemonkey. The demo works on Android, IOS, OSX, and Windows. It utilizes the native platform HTTP client component TNetHTTPClient in Delphi XE8. Basic HTTP authentication sends an HTTP header field containing a Base64 encoded user and password. You should use SSL/TLS encryption with your connections if you are using basic HTTP authentication for enhanced security. Unless you are using a session you will need to send the basic HTTP authentication header each time you make an HTTP request. An alternative method is to just POST your username and password via an HTTP request and then set up a session variable which you would pass back to the server on each additional request. You should be able to use this example with Appmethod as well. Here is a code snippet from the demo:

var
LResponse: IHTTPResponse;
BasicAuth: TNetHeader;
begin
if (eUser.Text <> '') or (ePwd.Text <> '') then
begin
BasicAuth := TNetHeader.Create('Authorization',
'Basic ' + Encode64(eUser.Text + ':' + ePwd.Text));
end;
try
LResponse := NetHTTPRequest1.Get(eURL.Text);
m1.Text := LResponse.ContentAsString;
except
on e: Exception do
showmessage(e.Message);
end;
