錯誤：類型'（（鍵：字符串，值：任何）''沒有下標成員帶有json

Question

我是Swift 3的新手，而json存在這個問題，這是我的功能，我不知道這是否是正確的方法

public static func parseResultsJSON(responseCars: [String : Any?]) -> Array<MisAutos>{
    var arrayMisAutos : [MisAutos] = [MisAutos]()

    if responseCars.count > 0{
        if let jArrayCars = responseCars[KeyWords.INFORMACION_G] as? [String : Any] {
            for jObjectCars in jArrayCars{

                let cars : MisAutos = MisAutos()

                cars.setAgAuto(agAuto: jObjectCars[KeyWords.AG_AUTO] as! String)

                cars.setMarca(marca: jObjectCars[KeyWords.MARCA] as! String)

                cars.setModelo(modelo: jObjectCars[KeyWords.MODELO] as! String)

                cars.setAgTipo(agTipo: jObjectCars[KeyWords.Ag_TIPO] as! String)

                cars.setNoSerie(noSerie: jObjectCars[KeyWords.NO_SERIE] as! String)

                cars.setUrlImage(urlImage: jObjectCars[KeyWords.ARRAY_IMAGES] as! [Int : String])

                cars.setPlacas(placas: jObjectCars[KeyWords.PLACAS] as! String)

                arrayMisAutos.append(cars);

            }
        }
    }
    return arrayMisAutos;
}

這是我的json

["Info": Optional(<__NSArrayM 0x618000054580>(
{
    id = 1;
    "type" = a;
    name = ACURA;
    Model = ILX;
    images =     (
    "werewr.werewr/images/image0.jpg",
    "werwer.werwer/images/image1.jpg",
    "werwer.werwer/images/image2.jpg",
    "werwer.werwer/images/image3.jpg"
    );
},
    {
        id = 2;
        "type" = b;
        name = BMW;
        Model = X6;
        images =     (
            "werewr.werewr/images/image0.jpg",
            "werwer.werwer/images/image1.jpg",
            "werwer.werwer/images/image2.jpg",
            "werwer.werwer/images/image3.jpg"
        );
}
    )
    ), "AutosPlan": Optional(3), "success": Optional(1)]

謝謝！

您的輸入參數錯誤。 它應該是字典的數組，而不僅僅是字典。 代替這個：

public static func parseResultsJSON(responseCars: [String : Any]) -> Array<MisAutos>{

你需要這個：

public static func parseResultsJSON(responseCars: [[String : Any]]) -> Array<MisAutos>{

這些值也不應該是可選的。 您也不應使用強制轉換，除非您100％的JSON響應始終正確。
