Custom messages from guards

I’ve a guard which returns false if the request doesn’t have correct jwt token or has expired jwt token. But I’m not being able to send the message back to notify why the request is 403 forbidden.

here’s my code

@Guard()
export class AuthGuard implements CanActivate {

    canActivate(req: Request, context: ExecutionContext): Promise<boolean> {
        return new Promise<boolean>((resolve, reject) => {
            if (req.headers.authorization && req.headers.authorization.toString().split(' ')[0] === 'Bearer') {
                const token: string = req.headers.authorization.toString().split(' ')[1];
                Database.Connection.then((connection: Connection) => {
                    const decoded = jwt.verify(token, 'secret');

                    connection.getRepository(User).findOneById(decoded.data).then((user: User) => {
                        (req as any).user = user;
                        resolve(true);
                    });
                }).catch((err) => {
                    resolve(false);
                });
            } else {
                resolve(false);
            }
        });
    }
}

@nmabhinandan of course! I see there’s no example in the docs. Good point, maybe I should create one 🙂

Hi @nmabhinandan, It’s easy. Instead of returning false, just throw a HttpException.
