我试过编码参数，它对我来说很好。请查看以下代码。

var wkWebView = WKWebView()

override func viewDidLoad()
{
    super.viewDidLoad()

    self.automaticallyAdjustsScrollViewInsets = false
    self.wkWebView.translatesAutoresizingMaskIntoConstraints = false
    self.wkWebView.frame =  CGRect.init(x: 0, y: 0, width: self.wkWebView.frame.size.width, height: self.wkWebView.frame.size.height)
    self.view.addSubview(wkWebView)

    loadUrl()
}
override func viewWillLayoutSubviews()
{
    super.viewWillLayoutSubviews()
    self.wkWebView.frame =  CGRect.init(x: 0, y: 0, width: self.view.frame.size.width, height: self.view.frame.size.height)
    self.wkWebView.contentMode = .scaleAspectFit
}
func loadUrl()
{
    let webConfiguration = WKWebViewConfiguration()
    webConfiguration.allowsInlineMediaPlayback = true

    let url_join = "v=1p38GWfCIhQ"

    let myURL = URL(string: "https://www.youtube.com/watch?")
    var myRequest = URLRequest(url: myURL!)
    myRequest.httpMethod = "POST"
    myRequest.httpBody = url_join.data(using: String.Encoding.utf8)
    wkWebView.load(myRequest)
}

我希望它对你也有用。 ：）

For me this Code worked fine. Notice, I Used http:// and not https://. But you already have set the settings for http:// to work.

import UIKit
import WebKit

class ViewController: UIViewController, WKNavigationDelegate {

@IBOutlet weak var webView: WKWebView!
private let url = URL(string: "http://www.google.com")

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
    let request = URLRequest(url: url!)
    webView = WKWebView(frame: self.view.frame)
    self.view.addSubview(webView)
    webView.navigationDelegate = self
    webView.load(request)
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

}
