How to use Vapor Middleware

[saroar]

how do i can use it ? is there any option?

[saroar]

import Vapor
import JWT
import MongoKitten

public final class JWTMiddleware: Middleware {
    public init() {}

    public func respond(to request: Request, chainingTo next: Responder) -> EventLoopFuture<Response> {

        guard let token = request.headers.bearerAuthorization?.token.utf8 else {
            return request.eventLoop.makeFailedFuture(
                Abort(.unauthorized, reason: "Missing authorization bearer header")
            )
        }

        do {
            request.payload = try request.jwt.verify(Array(token), as: Payload.self)
        } catch let JWTError.claimVerificationFailure(name: name, reason: reason) {
            request.logger.error("JWT Verification Failure: \(name) \(reason)")
            return request.eventLoop.makeFailedFuture(JWTError.claimVerificationFailure(name: name, reason: reason))
        } catch let error {
            return request.eventLoop.makeFailedFuture(
                Abort(.unauthorized, reason: "You are not authorized this token \(error)")
            )
        }

        return next.respond(to: request)
    }
}

extension AnyHashable {
    static let payload: String = "jwt_payload"
}

extension Request {
    var loggedIn: Bool {
        return self.storage[PayloadKey.self] != nil ?  true : false
    }

    var payload: Payload {
        get { self.storage[PayloadKey.self]! } // should not use it
        set { self.storage[PayloadKey.self] = newValue }
    }
}

my routes 
try app.group("v1") { api in
    let events = api.grouped("events")
    let eventsAuth = events.grouped(JWTMiddleware())
    try eventsAuth.register(collection: EventController() )
}
// inside controller i use like this 
if request.loggedIn == false { throw Abort(.unauthorized) }

but for vapor-router no option

Hi @saroar! Since this is a question and not a bug report, I'm going to convert this to a discussion where more eyes might see it. If there is a deficiency in the library we'd definitely take a PR to correct it, though!
