swift - 使用 Alamofire 创建一个标准的 API Router

Question

按照 Alamofire 文档，创建和使用路由器进行 CRUD 和授权的方法是

    enum Router: URLRequestConvertible {
        static let baseURLString = "http://example.com"
        static var OAuthToken: String?

        case CreateUser([String: AnyObject])
        case ReadUser(String)
        case UpdateUser(String, [String: AnyObject])
        case DestroyUser(String)

        var method: Alamofire.Method {
            switch self {
            case .CreateUser:
                return .POST
            case .ReadUser:
                return .GET
            case .UpdateUser:
                return .PUT
            case .DestroyUser:
                return .DELETE
            }
        }

        var path: String {
            switch self {
            case .CreateUser:
                return "/users"
            case .ReadUser(let username):
                return "/users/\(username)"
            case .UpdateUser(let username, _):
                return "/users/\(username)"
            case .DestroyUser(let username):
                return "/users/\(username)"
            }
        }

        // MARK: URLRequestConvertible

        var URLRequest: NSURLRequest {
            let URL = NSURL(string: Router.baseURLString)!
            let mutableURLRequest = NSMutableURLRequest(URL: URL.URLByAppendingPathComponent(path))
            mutableURLRequest.HTTPMethod = method.rawValue

            if let token = Router.OAuthToken {
                mutableURLRequest.setValue("Bearer \(token)", forHTTPHeaderField: "Authorization")
            }

            switch self {
            case .CreateUser(let parameters):
                return Alamofire.ParameterEncoding.JSON.encode(mutableURLRequest, parameters: parameters).0
            case .UpdateUser(_, let parameters):
                return Alamofire.ParameterEncoding.URL.encode(mutableURLRequest, parameters: parameters).0
            default:
                return mutableURLRequest
            }
        }
    }

Alamofire.request(Router.ReadUser("mattt")) // GET /users/mattt

但是这个 Router 只适用于用户模型，我想知道是否有任何方法可以将这个 Router 用于多个模型。

看这里: Proper usage of the Alamofire's URLRequestConvertible

他们也在尝试做同样的事情，但他们认为把它做大可能会很难处理
