Alamofire Request call with: Parameters, Headers and Body not working

问题

I have two questions with regards to the Alamofire code below.

My JSON fails if I remove the ?action=heartbeat at the end of the URL even though I have action = heartbeat in the parameters, why?

How do I add my JSON data/body in the AF.request code below?

let urlString   = "https://intelipos.dynalias.net/ioc/rest.asp?action=heartbeat"
let parameters  = ["action":"heartbeat"]
let headers: HTTPHeaders = ["Content-Type":"application/json"]

AF.request(urlString, method: .post, parameters: parameters, encoding:  URLEncoding.httpBody, headers: headers).responseJSON { response in
  switch response.result {
  case .success:
    print("Validation Successful")
  case let .failure(error):
    print(error)
  }
}

Question One

You need to encode as a querystring

let urlString   = "https://intelipos.dynalias.net/ioc/rest.asp"
let parameters  = ["action":"heartbeat"]
let headers: HTTPHeaders = ["Content-Type":"application/json"]

AF.request(urlString, method: .post, parameters: parameters, encoding:  URLEncoding.queryString, headers: headers).responseJSON { response in
  switch response.result {
  case .success:
    print("Validation Successful")
  case let .failure(error):
    print(error)
  }
}

Question Two

You have to prepare an encodable model and pass it in parameters argument and set encoding to JSONEncoding.default

Something like that.

let parameters: [String: Any] = [
            "request_token" : LoginVC.REQUEST_TOKEN
        ]


        Alamofire.request("https://api.com"
, method: .post, parameters: parameters, encoding: JSONEncoding.default , headers: nil)
