使用这个WKNavigationDelegate方法

public func webView(_ webView: WKWebView, decidePolicyFor navigationAction: WKNavigationAction, decisionHandler: @escaping (WKNavigationActionPolicy) -> Swift.Void) {
        if(navigationAction.navigationType == .other) {
            if navigationAction.request.url != nil {
                //do what you need with url
                //self.delegate?.openURL(url: navigationAction.request.url!)
            }
            decisionHandler(.cancel)
            return
        }
        decisionHandler(.allow)
    }

希望这可以帮助
