Write a function to get json data. if its Post method

let todosEndpoint: String = Your Url
            let  paramss: Parameters = ["user_id": self.userId]
            Alamofire.request(
                todosEndpoint,
                method: .post,
                parameters: paramss,
                headers: ["Content-Type": "application/x-www-form-urlencoded"])
                .responseJSON { response in
                    switch response.result {
                    case .success:
                            //if json data is a array
                            let json = JSON(response.result.value as Any)
                            if let codes = json.array {
                                for eachCode in codes {
                                    let userName = eachCode["username"].stringValue
                                     print("userName is\(userName)")

                                }
                            }

                            break

                        case .failure:
                            break
                        }
                }
