ios - Using manager.request with POST

Question

I want to send a POST request with Alamofire SessionManager.

I read the documentation on https://github.com/Alamofire/Alamofire/blob/master/Documentation/Alamofire%204.0%20Migration%20Guide.md#parameter-encoding-protocol

but I don't see an example for using request and POST, only upload.

The examples it gives:

let parameters: Parameters = ["foo": "bar"]

Alamofire.request(urlString, parameters: parameters) // Encoding => URLEncoding(destination: .methodDependent)
Alamofire.request(urlString, parameters: parameters, encoding: URLEncoding(destination: .queryString))
Alamofire.request(urlString, parameters: parameters, encoding: URLEncoding(destination: .httpBody))

// Static convenience properties (we'd like to encourage everyone to use this more concise form)
Alamofire.request(urlString, parameters: parameters, encoding: URLEncoding.default)
Alamofire.request(urlString, parameters: parameters, encoding: URLEncoding.queryString)
Alamofire.request(urlString, parameters: parameters, encoding: URLEncoding.httpBody)

My code is:

manager.request(url, method: .post, parameters: parameters, encoding: .url) .responseJSON { response in fulfill(response) }

which conforms to the method signature (from what I can tell) but I get an error "Extra parameter method: in call.

You need conform URLRequest with your parameters in body as Data

This code can help you

    var request = URLRequest(url: urlString!)
    request.httpMethod = "POST"
    request.setValue("application/json", forHTTPHeaderField: "Content-Type")

    request.httpBody = try! JSONSerialization.data(withJSONObject: parameters)

    manager.request(request)
           .responseJSON { response in
                fulfill(response)
        }

Hope this helps
