Wie analysiert man die JSON-Antwort von Alamofire API in Swift?

Folgenden code habe ich geschrieben und ich erhalte die Antwort im JSON-aber auch den Typ des JSON ist "AnyObject" und ich bin nicht in der Lage zu konvertieren, in ein Array, so dass ich verwenden können, dass.

Alamofire.request(.POST, "MY URL", parameters:parameters, encoding: .JSON) .responseJSON
{
    (request, response, JSON, error) in

    println(JSON?)
}

Die Antwort für Swift 2.0 Alamofire 3.0 sollte eigentlich mehr wie folgt Aussehen:

Alamofire.request(.POST, url, parameters: parameters, encoding:.JSON).responseJSON
{ response in switch response.result {
                case .Success(let JSON):
                    print("Success with JSON: \(JSON)")

                    let response = JSON as! NSDictionary

                    //example if there is an id
                    let userId = response.objectForKey("id")!

                case .Failure(let error):
                    print("Request failed with error: \(error)")
                }
    }

https://github.com/Alamofire/Alamofire/blob/master/Documentation/Alamofire%203.0%20Migration%20Guide.md

UPDATE für Alamofire 4.0 und Swift 3.0 :

Alamofire.request(url, method: .post, parameters: parameters, encoding: JSONEncoding.default)
            .responseJSON { response in
                print(response)
//to get status code
                if let status = response.response?.statusCode {
                    switch(status){
                    case 201:
                        print("example success")
                    default:
                        print("error with response status: \(status)")
                    }
                }
//to get JSON return value
            if let result = response.result.value {
                let JSON = result as! NSDictionary
                print(JSON)
            }

        }

wie oben schon erwähnt, dass Sie verwenden können, SwiftyJSON Bibliothek und Ihre Werte wie ich es unten getan

Alamofire.request(.POST, "MY URL", parameters:parameters, encoding: .JSON) .responseJSON
{
    (request, response, data, error) in

var json = JSON(data: data!)

       println(json)   
       println(json["productList"][1])                 

}

mein json-Produkt-Liste Rückkehr aus Skript

{ "productList" :[

{"productName" : "PIZZA","id" : "1","productRate" : "120.00","productDescription" : "PIZZA AT 120Rs","productImage" : "uploads\/pizza.jpeg"},

{"productName" : "BURGER","id" : "2","productRate" : "100.00","productDescription" : "BURGER AT Rs 100","productImage" : "uploads/Burgers.jpg"}    
  ]
}

Ausgabe :

{
  "productName" : "BURGER",
  "id" : "2",
  "productRate" : "100.00",
  "productDescription" : "BURGER AT Rs 100",
  "productImage" : "uploads/Burgers.jpg"
}

Alamofire.request(.GET, URLString, parameters: ["foo": "bar"])
    .responseJSON { request, response, result in
        switch result {

        case .Failure(let data, let error):
            print("Request failed with error: \(error)")

            if let data = data {

Ich bin weder ein JSON-Experte noch ein Swift-Experte, aber das folgende ist für mich arbeiten. 🙂 Habe ich extrahiert den code aus meiner aktuellen app, und nur verändert "MyLog um println" und mit Leerzeichen eingerückt, um es zu bekommen, um zu zeigen, wie ein code-block (hoffentlich habe ich nicht, es zu brechen).

func getServerCourseVersion(){

    Alamofire.request(.GET,"\(PUBLIC_URL)/vtcver.php")
        .responseJSON { (_,_, JSON, _) in
          if let jsonResult = JSON as? Array<Dictionary<String,String>> {
            let courseName = jsonResult[0]["courseName"]
            let courseVersion = jsonResult[0]["courseVersion"]
            let courseZipFile = jsonResult[0]["courseZipFile"]

            println("JSON:    courseName: \(courseName)")
            println("JSON: courseVersion: \(courseVersion)")
            println("JSON: courseZipFile: \(courseZipFile)")

          }
      }
}

Hoffe, das hilft.

Edit:

Referenz, hier ist, was mein PHP-Skript gibt:

[{"courseName": "Training Title","courseVersion": "1.01","courseZipFile": "101/files.zip"}]

Swift 3, Alamofire 4.4 und SwiftyJSON:

Alamofire.request(url, method: .get)
  .responseJSON { response in
      if response.data != nil {
        let json = JSON(data: response.data!)
        let name = json["people"][0]["name"].string
        if name != nil {
          print(name!)
        }
      }
  }

Analysieren diese JSON-input:

{
  people: [
    { name: 'John' },
    { name: 'Dave' }
  ]
}

Fand ich einen Weg, um zu konvertieren die Antwort.Ergebnis.Wert (innerhalb eines Alamofire responseJSON-Verschluss) in das JSON-format, die ich benutze in meiner app.

Ich bin mit Alamofire 3 und Swift 2.2.

Hier ist der code, den ich verwendet:

    Alamofire.request(.POST, requestString,
                      parameters: parameters,
                      encoding: .JSON,
                      headers: headers).validate(statusCode: 200..<303)
                                       .validate(contentType: ["application/json"])
                                       .responseJSON { (response) in
        NSLog("response = \(response)")

        switch response.result {
        case .Success:
            guard let resultValue = response.result.value else {
                NSLog("Result value in response is nil")
                completionHandler(response: nil)
                return
            }

            let responseJSON = JSON(resultValue)

            //I do any processing this function needs to do with the JSON here

            //Here I call a completionHandler I wrote for the success case
        break
        case .Failure(let error):
            NSLog("Error result: \(error)")
            //Here I call a completionHandler I wrote for the failure case
            return
        }

Normalerweise verwende ich Glanz Bibliothek zum serialisieren oder Deserialisieren von JSON in iOS. Ich habe zum Beispiel JSON sieht wie folgt aus:

{"ABDC":[{"AB":"qwerty","CD":"uiop"}],[{"AB":"12334","CD":"asdf"}]}

Erste, ich Modell die JSON-array in Glanz-Struktur:

Struct Struct_Name: Decodable {
   let IJ: String?
   let KL: String?
   init?(json: JSON){
       self.IJ = "AB" <~~ json
       self.KL = "CD" <~~ json
   }
}

Und dann in Alamofire responseJSON, mache ich das folgende Sache:

Alamofire.request(url, method: .get, paramters: parametersURL).validate(contentType: ["application/json"]).responseJSON{ response in
 switch response.result{
   case .success (let data):
    guard let value = data as? JSON,
       let eventsArrayJSON = value["ABDC"] as? [JSON]
    else { fatalError() }
    let struct_name = [Struct_Name].from(jsonArray: eventsArrayJSON)//the JSON deserialization is done here, after this line you can do anything with your JSON
    for i in 0 ..< Int((struct_name?.count)!) {
       print((struct_name?[i].IJ!)!)
       print((struct_name?[i].KL!)!)
    }
    break

   case .failure(let error):
    print("Error: \(error)")
    break
 }
}

Die Ausgabe aus dem code oben:

qwerty
uiop
1234
asdf
