swift - 如何使用来自像 turbo 360 这样的在线服务器的 JSON 文件？

Question

I am using a do catch scenario to try a JSONDecoder(), the only >problem is that I keep catching the error, but when I review my code I >can't see the error, maybe I need another set of eyes to help me out >of this one!

我将我的 JSON 文件放在 turbo360 的一个存储文件夹中，我也尝试过 gitHub，但我相信两者都不起作用。

import UIKit

class ViewController: UIViewController {

    final let url = URL(string: "https://storage.turbo360.co/portfolio-website-hxoc6m/actors")

    override func viewDidLoad() {
        super.viewDidLoad()
        downloadJson()
    }

    func downloadJson() {
        guard let downloadURL = url else { return }
        URLSession.shared.dataTask(with: downloadURL) { data, urlResponse, error in
            guard let data = data, error == nil, urlResponse != nil else {
                print("something is wrong")
                return
            }
            print("downloaded")
            print(downloadURL)
            do
            {
                    let decoder = JSONDecoder()
                    let actors = try decoder.decode(Actors.self,  from: data)
                    print(actors)
            } catch {
                    print("Something wrong after downloaded")
            }
        }.resume()
    }
}

I supposed to get: JSONDonloadingSwift4.Actors as confirmation that my JSON file has been accessed and decoded

您的 JSON 无效。您缺少最后一个图像 URL 上的开头 "。修复该问题，只要您的 Actor 定义匹配，您就应该没问题。jsonlint 对于检查 JSON 非常有用结构。
