Question

我想在WKWebView中使用密码/用户名（基本）授权打开一个网站为此，我使用方法didReceiveAuthenticationChallenge。

import UIKit
import WebKit

class ViewController: UIViewController {

@IBOutlet weak var container: UIView!
var webView: WKWebView!

override func viewDidLoad() {
    super.viewDidLoad()
    webView = WKWebView()
    container.addSubview(webView)
    let urlStr = "https://vplan.bielefeld-marienschule.logoip.de/subst_002.htm"
    let url = NSURL(string: urlStr)!
    let request = NSURLRequest(url: url as URL)
    webView.load(request as URLRequest)
}
func webView(webView: WKWebView, didReceiveAuthenticationChallenge challenge: URLAuthenticationChallenge, completionHandler: (URLSession.AuthChallengeDisposition, URLCredential?) -> Void){
    if challenge.protectionSpace.host == "https://vplan.bielefeld-marienschule.logoip.de/subst_002.htm" {
        let userStr = "********"
        let passwordStr = "********"
        let credential = URLCredential(user: userStr, password: passwordStr, persistence: URLCredential.Persistence.forSession)
        challenge.sender?.use(credential, for: challenge)
        completionHandler(.useCredential, credential)
    }
}

override func viewDidAppear(_ animated: Bool) {
    let frame = CGRect(x: 0, y: 0, width: container.bounds.width, height: container.bounds.height)
    webView.frame = frame

但由于某种原因，它不起作用添加代码行

completionHandler(URLSession.AuthChallengeDisposition.UseCredential, credential)

就像在此处的说明中一样：Authentication with WKWebView in Swift产生了错误我还尝试将challenge.protectionSpace.host更改为vplan.bielefeld-marienschule.logoip.de:443，在Safari pop-up中显示为登录地址，并进入服务器的IP地址（93.206.31.253）。

希望你能帮助我。谢谢！

在您的代码中，您尚未将Web视图的导航委托设置为控制器。

将控制器的定义更改为：

class ViewController: UIViewController, WKNavigationDelegate

创建Web视图后，将导航委托设置为控制器：

webView.navigationDelegate = self

根据您使用的是Swift 3，您可能需要将方法的签名更改为webView(_:didReceive:completionHandler:)。

WKWebView授权
