OAuth: Customize login and confirmation forms
Different HTML forms may be displayed to the end users in some OAuth2 scenarios e.g. when login credentials should be entered via web-browser. By default TElHTTPSServer uses built-in forms code that may be customized.
TElHTTPSServer.AuthFormTemplate property may be used to assign a custom login form. The default form looks the next way:
<html> <head> <title>EldoS HTTP Login Page</title> </head> <body> <center> <h1>Enter login credentials</h2> <form action="%URL%" method="POST"> Login:<br/><input type="text" name="%LOGIN%"/><br/> Password:<br/><input type="password" name="%PASSWORD%"/><br/> <input type="hidden" name="%CSRF%" value="%CSRF_TOKEN%"/> <input type="submit" value="Login"/> </form> </center> </body> </html>where
TElHTTPSServer.ConfirmPageTemplate is used to assign the custom login confirmation page. The default form looks the next way:
<html> <head><title>EldoS OAuth2 Confirmation Page</title></head> <body> <center> <h1>An application would like to connect to your account!</h1> <h2>The application %APPNAME% would like the ability to access:</h2> <h3>%SCOPE%</h3> <button type="button" id="yes">Yes</button><button type="button" id="no">No</button> </center> <script> document.getElementById(yes).onclick = function() { window.location = "%ALLOW_URL%"; }; document.getElementById(no).onclick = function() { window.location = "%DENY_URL%"; }; </script> </body> </html>where
