我正在尝试从我的数据库中提取图像在swift。我可以检索价格、视频和p_name，但不能检索图像。我想用数据库中的图像更新updateImage UIImageView，但我得到两个错误。
Error one说道：
类型“ViewController.Class”不符合协议“Encodable”
Error two说：
类型“ViewController.Class”不符合协议“Dec
对此有哪些好的变通方法？
下面是JSON：

{
"id":"1",
"p_name":"item_one",
"image":"item_one.png"
}
{
"id":"2","p_name":
"item_two","image":
"item_two.img"
}

Swift代码：

import UIKit

class ViewController: UIViewController {

@IBOutlet weak var updateLabel: UILabel!

@IBOutlet weak var updateImage: UILabel!

struct Class: Codable
{
    let id: String
    let p_name: String
    let image: String

}

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.

    let url = URL(string: "http://host-2:8888//getClasses.php")

    // Load the URL
    URLSession.shared.dataTask(with: url!, completionHandler: {(data, response, error) in
        // If there are any errors don't try to parse it, show the error
        guard let data = data, error == nil else { print(error!); return }

        let decoder = JSONDecoder()
        let classes = try! decoder.decode([Class].self, from: data)
        // Print out the classes to the console - try sticking this in a table view :)
        for myClass in classes {

            self.updateLabel.text = myClass.p_name
            self.updateImage.text = myClass.image

        }

    }).resume()

    }
}
