POST request with data in body with Alamofire 4

Question

how is it possible to send a POST request with a data in the HTTP body with Alamofire 4? I used custom encoding at swift 2.3 it was working good. I converted my code swift 3

Answer 1

Alamofire for GET and POST method using Alamofire

1.Create a file named "GlobalMethod" for multiple use

import Alamofire
class GlobalMethod: NSObject {

    static let objGlobalMethod = GlobalMethod()

    func ServiceMethod(url:String, method:String, controller:UIViewController, parameters:Parameters, completion: @escaping (_ result: DataResponse) -> Void) {

            var headers = Alamofire.SessionManager.defaultHTTPHeaders
            headers["HeaderKey"] = "HeaderKey"
            if method == "POST" {
                methodType = .post
                param = parameters
            }
            else {
                methodType = .get
            }
            Alamofire.request(url, method: methodType, parameters: param, encoding: JSONEncoding.default, headers:headers
                ).responseJSON
                { response in

                    completion(response)
            }
        }
}

2. In the View Controller call "ServiceMethod" created in GlobalMethod by sending values to call API Service

   let urlPath = "URL STRING"
   let methodType = "GET" or "POST" //as you want
   let params:[String:String] = ["Key":"Value"]
   
   GlobalMethod.objGlobalMethod.ServiceMethod(url:urlPath, method:methodType, controller:self, parameters:params)
           {
               response in
   
               if response.result.value == nil {
                   print("No response")
                   return
               }
               else {
                 let responseData = response.result.value as! NSDictionary
                 print(responseData)
               }
           }
