ios – Alamofire error request with parameter with out identify

I am getting an error whereas making an attempt to encode a parameter right into a request url.

Right here is my perform to get the request url:

func asURLRequest() throws -> URLRequest {
        let url = attempt baseURL.asURL().appendingPathComponent(path)
        var request = URLRequest(url: url)
        request.methodology = methodology
        if methodology == .get {
            request = attempt URLEncodedFormParameterEncoder().encode(parameters, into: request)
        } else if methodology == .submit {
            request = attempt JSONParameterEncoder().encode(parameters, into: request)
            request.setValue("software/json", forHTTPHeaderField: "Settle for")
        }
        return request
    }

It’s working when the parameter is a dictionary like [“id”: 1]. The url can be:
http://…/api/v1/objects/?id=1

I need to go the parameter 1 solely, so the url can be like this:
http://…/api/v1/objects/1

Nevertheless it does not work, I get this error from Alamofire:

requestRetryFailed(retryError:
Alamofire.AFError.requestRetryFailed(retryError:
Alamofire.AFError.parameterEncoderFailed(purpose:
Alamofire.AFError.ParameterEncoderFailureReason.encoderFailed(error:
Alamofire.URLEncodedFormEncoder.Error.invalidRootObject(“string(“1″)”)))
