arrays - 在参数请求中传递字符串数组 - swift 5

Question

在参数请求中传递字符串数组 - swift 5。我想从 alamofire 请求的参数中发送一个数组。

这是 Postman 上的请求:

这是我的解决方案:

var Token : String?
       var  tasksMO = [NSManagedObject]()
       let request = NSFetchRequest<NSFetchRequestResult>(entityName: "ConfirmActivationEntity")
       do {
           let results = try pe.context.fetch(request)
           tasksMO = results as! [NSManagedObject]
           for taskmo in tasksMO {
               Token = (taskmo.value(forKey: "access_token")  as! String )
           }
           print("assbil")
       } catch {
           print("fild")
       }
 print(" Token :\(Token!)")
let levels  : [String]  = ["+972569431827","+972598110437","+972592923343","3555656","00970567163651","258258"]

let paramsJSON = JSON(levels)
debugPrint(paramsJSON)
let parameters : [String : Any] = ["contacts":paramsJSON,"platform":2]


 let headers : HTTPHeaders = ["Authorization":"Bearer \(Token!)","Accept-Language" : Locale.current.languageCode ?? "ar", "Content-Type" : "application/x-www-form-urlencoded","Accept" : "application/json"]

guard let url = URL(string: "\(UrlApi.url)\(UrlApi.contactsPost)") else { return }

   sdLoader.startAnimating(atView: self.view)
   Alamofire.request(url, method: .post, parameters: parameters, headers: headers).responseJSON { response in
     if let error = response.error {
           print(error)
           return
       }

       if let status = response.response?.statusCode {
        print(status)
        print(response.result.value!)
         switch(status){
           case 200:

        self.sdLoader.stopAnimation()
         do{
              let decoder = JSONDecoder()
              let userResultDec = try decoder.decode(ContactsJSON.self, from: response.data!)
              decoder.keyDecodingStrategy = .convertFromSnakeCase
               if userResultDec.status == true {

                print(userResultDec.items)

               } else if userResultDec.status == false {
                   self.showAlert(title: "رسالة", message: "هناك خطا بالمعلومات المدخلة", style: .alert)
           }


          }  catch let parsingError {
               print("Error", parsingError)
               MessageBox.Show(Message: " \(parsingError) , خطأ في السيرفير ", MyVC: self)
          }
           case 401 :
            self.sdLoader.stopAnimation()
              print("error with response status: \(status)")
              print("خطأ في السيرفير")
              MessageBox.Show(Message: "error with response status: \(status) , خطأ في السيرفير ", MyVC: self)
           case 404 :
            self.sdLoader.stopAnimation()
              print("error with response status: \(status)")
              print("خطأ في السيرفير")
              MessageBox.Show(Message: "error with response status: \(status) , خطأ في السيرفير ", MyVC: self)

         case 500:
              MessageBox.Show(Message: "error with response status: \(status) , خطأ في السيرفير ", MyVC: self)
            default:
             print("Error")

           }
       }
    }

问题是: 数组中的项目不会出现在服务器的引用响应中

我正在将 Alamofire pod 和 SwiftyJson pod 与 iOS 13、Swift 5 和 Xcode 11 一起使用。

Alamofire/Swift 中的 application/x-www-form-urlencoded 对话出现问题。它确实以 postman 的方式工作。 Postman 会自动转换你的数组，但 swift 不会。

struct ArrayEncoding: ParameterEncoding {
  func encode(_ urlRequest: URLRequestConvertible, with parameters: Parameters?) throws -> URLRequest {
    var request = try URLEncoding().encode(urlRequest, with: parameters)
    request.url = URL(string: request.url!.absoluteString.replacingOccurrences(of: "%5B%5D=", with: "="))
    return request
  }
}
