TypeSafeHTTPBasic

public protocol TypeSafeHTTPBasic : TypeSafeCredentials

A TypeSafeCredentials plugin for HTTP basic authentication. This protocol will be implemented by a Swift object defined by the user. The plugin must implement a verifyPassword function which takes a username and password as input and returns an instance of Self on success or nil on failure. This instance must contain the authentication provider (defaults to HTTPBasic) and an id, uniquely identifying the user. The users object can then be used in TypeSafeMiddlware routes to authenticate with HTTP basic.

Usage Example:

public struct MyHTTPBasic: TypeSafeHTTPBasic {

   public var id: String

   static let users = ["John" : "12345", "Mary" : "qwerasdf"]

   public static let realm = "Login message"

   public static func verifyPassword(username: String, password: String, callback: @escaping (MyHTTPBasic?) -> Void) {
       if let storedPassword = users[username], storedPassword == password {
           callback(MyHTTPBasic(id: username))
       } else {
           callback(nil)
       }
   }
}

struct User: Codable {
   let name: String
}

router.get("/protected") { (authedUser: MyHTTPBasic, respondWith: (User?, RequestError?) -> Void) in
   let user = User(name: authedUser.id)
   respondWith(user, nil)
}
