IOS WKWebView 文件上传不工作

Question

我试图在 WKWebView 中运行一个网络应用程序，在我选择照片库中的图像后，它返回主页并且不上传图像。我收到以下消息:

我的代码:

import UIKit
import WebKit
class ViewController: UIViewController, UIImagePickerControllerDelegate,UINavigationControllerDelegate {

    @IBOutlet weak var webView: WKWebView!

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

    override func viewDidAppear(_ animated: Bool) {

        let url:URL = URL(string: "http://serivinho:8001/")!
        let urlRequest: URLRequest = URLRequest(url: url)
        webView.load(urlRequest);
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }
    override func dismiss(animated flag: Bool, completion: (() -> Void)?)
    {
        if self.presentedViewController != nil {
            super.dismiss(animated: flag, completion: completion)
        }
    }
}

当我将代码从 viewDidAppear 移动到 ViewDidLoad 时，问题似乎消失了

   override func viewDidLoad() {

        let url:URL = URL(string: "http://serivinho:8001/")!
        let urlRequest: URLRequest = URLRequest(url: url)
        webView.load(urlRequest);
    }

我还将目标版本更改为 10.3，并在代码中添加了 WKWebView，而不是在主 Storyboard中。

我仍然收到一些日志消息，但它们并没有阻止工作:
