Moya: Failure code 999

Hello, I use Mayo to wrap my network in my swift app. I want to connect with my own API.

I first created a test a User case :

public enum UserAPI {
    case Information
}

extension UserAPI: TargetType {
    public var baseURL: NSURL { return NSURL(string: "http://127.0.0.1:3000/user")!}

    public var path: String {
        switch self {
        case .Information:
            return "/"
        }
    }

    public var method: Moya.Method {
        return .GET
    }

    public var parameters: [String: AnyObject]? {
        return nil
    }

    public var sampleData: NSData {
        switch self {
        case .Information():
            return "{}".dataUsingEncoding(NSUTF8StringEncoding)!
        }
    }

    public func constructProvider(target: UserAPI) -> Endpoint<UserAPI> {
        let token = TokenAccess.sharedInstance.token!
        let endpoint: Endpoint<UserAPI> = Endpoint<UserAPI>(URL: "\(target.baseURL)\(target.path)", sampleResponseClosure: {.NetworkResponse(200, target.sampleData)}, method: target.method, parameters: target.parameters)
        return endpoint.endpointByAddingHTTPHeaderFields(["Authorization": "Bearer \(token)"])
    }
}

Then the call :

let provider = MoyaProvider<UserAPI>()
provider.request(UserAPI.Information) { (result) -> () in
    print("result request : \(result)")
}

And then the result :

result request : .Failure(Underlying(Error Domain=NSURLErrorDomain Code=-999 "cancelled" UserInfo={NSErrorFailingURLKey=http://127.0.0.1:3000/user/, NSLocalizedDescription=cancelled, NSErrorFailingURLStringKey=http://127.0.0.1:3000/user/}))

The base URL is okay. I am making a transition, in a network abstraction, I used Alamofire previously, and it worked well. I am trying to move my code to Moya.

Thanks in advance for your help. 👍
