Récupération de données à l'aide de swift 4

Question

J'essaie d'extraire des données de swift 4 et je n'ai aucune réponse.

1- J'ai ce morceau de code et je l'erreur « Type « JobSeekerDataAPI » ne sont pas conformes au protocole « décodables »

Après cela, je fait la demande:

class JobSeekerJsonRequests: NSObject{ 

class func jobSeekerRequest(completion: @escaping(_ error: Error?, _ jobSeekerData : JobSeekerDataAPI?) ->Void) { 

    let jsonURLString = URLs.jobSeeker 

    guard let url = URL(string: jsonURLString) else { return } 

    URLSession.shared.dataTask(with: url) { (data, response, error) in 

     guard let data = data else { return } 

     do { 
      let jobSeekerData = try 
       JSONDecoder().decode(JobSeekerDataAPI.self, from: data) 
      print(jobSeekerData) 

     }catch let jsonError { 
      print("Error serializing json: ", jsonError) 
     } 

    }.resume() 
} 

Et puis:

func userData(){ 

    JobSeekerJsonRequests.jobSeekerRequest { (error: Error?, jobSeekerData: JobSeekerDataAPI?) in 

     if let jobSeekerData = jobSeekerData { 

      self.myProfileJobTitle.text = jobSeekerData.most_recent_work_history?.position 
      self.menuProfileName.text = jobSeekerData.job_seeker_name 
      self.userNameLabel.text = jobSeekerData.first_name 
      self.userNameJobPositionLabel.text = jobSeekerData.most_recent_work_history?.position 
      self.userLocationLabel.text = jobSeekerData.location_country?.location_country_name 
      self.infoAboutLabel.text = jobSeekerData.about 
      self.userJobTitleLabel.text = jobSeekerData.most_recent_work_history?.position 

     } 
    } 

J'ai un problème pour comprendre les demandes de l'API becuase que je travaille sur ce et je n'ai eu aucune réponse de cela. J'apprends vite par moi-même ces 5 derniers mois et je suis coincé là-dessus. Désolé Si cela ressemble à une question stupide, mais c'est comme ça que les nouveaux mecs m'aiment et ont besoin d'aide.

Merci les gars!

Answer 1

La façon dont vous utilisez CodingKeys enum est incorrect.

Comme indiqué dans docs d'Apple:

Les noms des cas d'énumération doivent correspondre aux noms que vous avez donné aux propriétés correspondantes dans votre type.

Si les clés utilisées dans le format de données sérialisé ne correspondent pas aux noms de propriétés de votre type de données, fournir des clés alternatives en spécifiant chaîne comme type valeur brute pour les CodingKeys d'énumération . La chaîne que vous utilisez comme valeur brute pour chaque énumération est le nom de clé utilisé lors du codage et du décodage.

En bref:

1. nom de cas est exactement le même que le nom de la propriété
2. rawValue d'un cas particulier est le nom clé personnalisée que vous souhaitez utiliser .

Vous faites exactement le contraire de ce qui doit être fait.

Exemple:

struct JobSeekerDataAPI : Decodable 
{ 
    let job_seeker_id: String? 
    let job_seeker_name: String? 
    //Other properties 

    enum CodingKeys: String, CodingKey 
    { 
     case job_seeker_id = "jobSeekerID" //case name is same as property name 
     case job_seeker_name = "jobseekerName" 
     //Other cases 
    } 
} 

Pour plus de précisions, consultez: https://developer.apple.com/documentation/foundation/archives_and_serialization/encoding_and_decoding_custom_types

Vous devez faire la même chose pour tous les structs que vous voulez être Decodable.

Cela va sûrement résoudre votre problème.

Edit: Obtenir zéro après le décodage des données de réponse JSON

Je vous obtenez nil, vérifiez que votre API retourne en réponse. J'ai inclus un extrait de code de ce que vous la réponse API devrait ressembler et ce que vous obtiendrez comme résultat:

class JobSeekerJsonRequests: NSObject 
{ 
    class func jobSeekerRequest(completion: @escaping(_ error: Error?, _ jobSeekerData : JobSeekerDataAPI?) ->Void) 
    { 
     let jsonResponseString = "{\"jobSeekerID\":\"1234\",\"jobseekerName\":\"abcd\"}" //Something like this must be the format of your JSON response. Check the key names that are used here. 
     guard let data = jsonResponseString.data(using: .utf8) else { 
      return 
     } 

     do 
     { 
      let jobSeekerData = try 
      JSONDecoder().decode(JobSeekerDataAPI.self, from: data) 
      print(jobSeekerData) 
     } 
     catch let jsonError 
     { 
      print("Error serializing json: ", jsonError) 
     } 
    } 

    func userData() 
    { 
     //Your code 
    } 
} 

sortie vous obtiendrez après print(jobSeekerData) instruction est exécutée:

JobSeekerDataAPI(job_seeker_id: Optional("1234"), job_seeker_name: Optional("abcd")) 

Juste assurez-vous que vous utilisez les noms de clés correctes, puisque votre résultat en dépend complètement.

Remarque: Commencez par tester votre code avec moins de propriétés dans struct afin que le débogage soit facile. L'ajout de plus de code rend difficile le débogage du problème. Alors, commencez avec petit et puis finalement le rendre grand. Informez-moi si vous rencontrez toujours un problème.

Answer 2

Vous avez oublié d'ajouter CodingKeys ci-dessous pour enum CodingKeys: String, CodingKey

let most_recent_work_history: WorkHistory? 
let most_recent_education: EducationHistory?
