Question

我有Webview WKWebview我正在加载网址。加载的网站有登录页面和主页。登录后，用户将被定向到主页。登录时，会向用户发送cookie。我想得到这个cookie，在那个时刻需要用它进行HTTP调用。因为我是iOS新手，所以我获得了一些关于获取所有cookie和特定网址的信息。但是，对于特定的网址＆＃39;我没有在合适的时刻获得cookie，也不知道如何获得cookie。

所以，问题是我想知道如何观察用户已登录并且我在登录后获得了cookie。

我尝试了一些代码：

viewDidLoad中的观察者代码

NotificationCenter.default.addObserver(self, selector: #selector(cookiesConfigured(notification:)), name: .cooKieName, object: nil)

webView.addObserver(self, forKeyPath: "URL", options: .new, context: nil)

观察员方法

override func observeValue(forKeyPath keyPath: String?, of object: Any?, change: [NSKeyValueChangeKey : Any]?, context: UnsafeMutableRawPointer?) {

    print("fact "+keyPath!)

    if keyPath == "URL" {
        let clickedUrl = webView.url?.absoluteString as String!
        print("fact " + clickedUrl! )

        if clickedUrl == tokenURL {
            print("fact equal" )

            webView.removeObserver(self, forKeyPath: "URL")
            webView.addObserver(self, forKeyPath:#keyPath(WKWebView.estimatedProgress), options: .new, context: nil)


        }

    }else  if keyPath == #keyPath(WKWebView.estimatedProgress) {

        print("fact estimated progress")

        if webView.estimatedProgress == 1.0 {
            print("fact estimated progress 100")
             NotificationCenter.default.post(name: .cooKieName, object: nil)
        }

    }

  //  guard object as? WKWebView === webView, keyPath == #keyPath(WKWebView.estimatedProgress) else { return }

  //  print(Float(webView.estimatedProgress))


}

通知处理程序和Cookie getter方法

@objc func cookiesConfigured(notification: Notification){

    print("fact cookieconfigured")

    if let cookies = HTTPCookieStorage.shared.cookies(for: URL(string: tokenURL)!) {

         print("fact inLet")

        for cookie in cookies {

            print("fact inLet")

            print("fact \(cookie)")
            print("fact version \(cookie.version)")
            print("fact name \(cookie.name)")
            print("fact value \(cookie.value)")
            print("fact expiredate \(String(describing: cookie.expiresDate))")
            print("fact sessiononly \(cookie.isSessionOnly)")
            print("fact domain \(cookie.domain)")
            print("fact path \(cookie.path)")
            print("fact issecure \(cookie.isSecure)")
        }
    }

如何观察webview以获取iOS swift中特定页面的cookie？
