Publication de l'entrée utilisateur JSON dans Swift

Question

J'essaie de collecter des données de l'utilisateur et de l'envoyer à un service Web, mais je reçois une erreur "type de haut niveau invalide en écriture JSON" Je recueille les étapes du magasin de santé dans un autre fonction et toutes les données sont transmises correctement dans les variables userhealthprofile au fur et à mesure de leur impression. Mais quelque chose ne va pas avec mon code JSON

message d'erreur complète est

code

@IBAction func submitAction(sender: AnyObject) { 

    userHealthProfile.name = nameLabel.text 
    print(userHealthProfile.name) 

    userHealthProfile.age = Int(ageLabel.text!) 
    print(userHealthProfile.age) 

    userHealthProfile.heightInMeters = Int(heightLabel.text!) 
    print(userHealthProfile.heightInMeters) 

    userHealthProfile.weightInKilograms = Int(weightLabel.text!) 
    print(userHealthProfile.weightInKilograms) 

    for element in stepy.step { 
     print(element) 
    } 

    userHealthProfile.totalStepsCount = stepy.step 

    print("pressing button") 

    //create the url with URL 
    let url = URL(string: "www.thisismylink.com/postName.php")! 
    //change the url 

    //create the session object 
    let session = URLSession.shared 

    //now create the URLRequest object using the url object 
    var request = URLRequest(url: url) 
    request.httpMethod = "POST" //set http method as POST 

    do { 
     request.httpBody = try JSONSerialization.data(withJSONObject: userHealthProfile, options: .prettyPrinted) // pass dictionary to nsdata object and set it as request body 
    } catch let error { 
     print(error.localizedDescription) 
    } 

    request.addValue("application/json", forHTTPHeaderField: "Content-Type") 
    request.addValue("application/json", forHTTPHeaderField: "Accept") 

    //create dataTask using the session object to send data to the server 
    let task = session.dataTask(with: request as URLRequest, completionHandler: { data, response, error in 

     guard error == nil else { 
      return 
     } 
     guard let data = data else { 
      return 
     } 
     do { 
      //create json object from data 
      if let json = try JSONSerialization.jsonObject(with: data, options: .mutableContainers) as? [String: Any] { 
       print(json) 
       // handle json... 
      } 
     } catch let error { 
      print(error.localizedDescription) 
     } 
    }) 
    task.resume() 
} 

C'est ce que userprofile ressemble, ce que je dois envoyer comme JsonObject pour mon service Web.

class UserHealthProfile { 

    var name: String? 
    var age: Int? 
    var totalStepsCount: Array<Any>! 
    var heightInMeters: Int? 
    var weightInKilograms: Int? 

}

Je pense que vous devriez utiliser pour appeler Alamofire API web .. Voici l'exemple de code en fonction de vos besoins.

J'espère que cela vous aidera ...

func Submit(parametersToSend:NSDictionary) 
{ 


Alamofire.request(.POST, "http://www.thisismylink.com/postName.php",parameters: parametersToSend as? [String : AnyObject], encoding: .URL).responseJSON 
    { 
     response in switch response.2 
     { 
     case .Success(let JSON): 
      print(JSON) 
      let response = JSON as! NSDictionary 
      print("My Web Api Response: \(response)") 
      break 
     case .Failure(let error): 
      print("Request failed with error: \(error)") 
      break 
     } 

    } 

} 

Fonction Appel dans votre @IBAction func submitAction (expéditeur: ANYOBJECT) comme celui-ci

@IBAction func submitAction(sender: AnyObject) { 

let steps = stepy.step 
let name = nameLabel.text! 
let age = Int(ageLabel.text!) 
let height = Int(heightLabel.text!) 
let weight = Int(weightLabel.text!) 
let parameters = [ 
     "name": name 
     "age": age 
     "totalStepsCount": steps 
     "heightInMeters": height 
     "weightInKilograms": weight 
     ] 
self.submit(parametersToSend:parameters) 

}
