horse-basic-auth is a official middleware for working with basic authentication in APIs developed with the Horse framework.
We created a channel on Telegram for questions and support:

⚙️ Installation

Installation is done using the boss install command:

✔️ Compatibility

This middleware is compatible with projects developed in:

  • Delphi
  • Lazarus

⚡️ Quickstart Delphi

uses 
  Horse, 
  Horse.BasicAuthentication, // It's necessary to use the unit
  System.SysUtils;

begin
  // It's necessary to add the middleware in the Horse:
  THorse.Use(HorseBasicAuthentication(
    function(const AUsername, APassword: string): Boolean
    begin
      // Here inside you can access your database and validate if username and password are valid
      Result := AUsername.Equals('user') and APassword.Equals('password');
    end));
    
  // The default header for receiving credentials is "Authorization".
  // You can change, if necessary:
  // THorse.Use(HorseBasicAuthentication(MyCallbackValidation, THorseBasicAuthenticationConfig.New.Header('X-My-Header-Authorization')));

  // You can also ignore routes:
  // THorse.Use(HorseBasicAuthentication(MyCallbackValidation, THorseBasicAuthenticationConfig.New.SkipRoutes(['/ping'])));

  THorse.Get('/ping',
    procedure(Req: THorseRequest; Res: THorseResponse; Next: TProc)
    begin
      Res.Send('pong');
    end);

  THorse.Listen(9000);
end;

⚡️ Quickstart Lazarus

{$MODE DELPHI}{$H+}

uses
  {$IFDEF UNIX}{$IFDEF UseCThreads}
  cthreads,
  {$ENDIF}{$ENDIF}
  Horse,
  Horse.BasicAuthentication, // It's necessary to use the unit
  SysUtils;

procedure GetPing(Req: THorseRequest; Res: THorseResponse; Next: TNextProc);
begin
  Res.Send('Pong');
end;

function DoLogin(const AUsername, APassword: string): Boolean;
begin
  // Here inside you can access your database and validate if username and password are valid
  Result := AUsername.Equals('user') and APassword.Equals('password');
end;

begin
  // It's necessary to add the middleware in the Horse:
  THorse.Use(HorseBasicAuthentication(DoLogin));

  // The default header for receiving credentials is "Authorization".
  // You can change, if necessary:
  // THorse.Use(HorseBasicAuthentication(MyCallbackValidation, THorseBasicAuthenticationConfig.New.Header('X-My-Header-Authorization')));

  // You can also ignore routes:
  // THorse.Use(HorseBasicAuthentication(MyCallbackValidation, THorseBasicAuthenticationConfig.New.SkipRoutes(['/ping'])));

  THorse.Get('/ping', GetPing);

  THorse.Listen(9000);
end.
