Question

我正在尝试将数据从我的网站Javascript传递到我的应用程序，用Swift编写。

使用Javascript：

var messgeToPost = {
     "username": "testing123"
};
window.webkit.messageHandlers.loginSuccess.postMessage(messgeToPost);

夫特：

var webConfig:WKWebViewConfiguration {
    get {
        var webCfg:WKWebViewConfiguration = WKWebViewConfiguration()

        var userController:WKUserContentController = WKUserContentController()

        userController.addScriptMessageHandler(self, name: "loginSuccess")

        webCfg.userContentController = userController;

        return webCfg;
    }
}

override func viewDidLoad() {
     var userController:WKUserContentController = WKUserContentController()
     userController.addScriptMessageHandler(self, name: "loginSuccess")
     webView = WKWebView(frame: self.view.frame,
        configuration: webConfig)
     webView.loadRequest(NSURLRequest(URL: NSURL(string: URLPath)!))
}

func userContentController(userContentController: WKUserContentController, didReceiveScriptMessage message: WKScriptMessage) {
    if let messageBody:NSDictionary = message.body as? NSDictionary {
        let password:String = messageBody["password"] as! String

        print(password)
    }
}

不幸的是，永远不会调用print(password)。

我在这里缺少什么？

Answer 1

var messgeToPost = {
     "username": "testing123",
     "password": "password"
};

忘了添加密码

如何在WKWebView中将数据从Javascript传递到Swift？
