How to add parameters on middleware

[Faridalim]

Hi, thanks for making Alfred. I think it looks very easy and similar to Express which is a huge plus for me.

I have one question here. I want to add some auth middleware with roles in it. I can add this in express like in below picture

Could you guide me to do that in Alfred please? How to add parameters in middleware? Thank you..

Hello, better late than never,

I use it like this;

  sunucu.get("/test", (req, res) {
    return "hello";
  }, middleware: [exampleMiddlwareJWT]);

MiddlwareJWT(HttpRequest req, HttpResponse res) {
  try {
    var decodedToken = JWT.parse(req.headers.value('Authorization').toString().replaceAll("Bearer ", ""));
    decodedToken.expiresAt!.toInt() - (DateTime.now().millisecondsSinceEpoch / 1000).floor() <= 0
        ? throw "Token Expired"
        : "";

    decodedToken.subject == "token" ? "" : throw "It is not Token!";
    decodedToken.verify(signer) == false ? throw "Invalid Token" : "";

    var validator = JWTValidator(); // set claims you wish to validate
    Set<String> errors = validator.validate(decodedToken);
    if (errors.isNotEmpty) {
      throw "Errors Throwed!";
    }
  } catch (e) {
    res.statusCode = 401;
    return {'message': '$e'};
  }
}

This is a simple JWT control, but you can make any control you want. You can add more than one control to this list [MiddlwareJWT]
