在webview组件中打开login.microsoftonline.com页面

Question

我在javafx的webview组件中打开login.microsoftonline.com页面时遇到了问题。我有简单的代码，可以毫不费力地打开这个页面：

   WebView webView = new WebView();
    WebEngine webEngine = webView.getEngine();
    var url = "https://login.microsoftonline.com/";
    webEngine.load(url);

    VBox root = new VBox();
    root.getChildren().add(webView);
    Scene scene = new Scene(root);
    stage.setScene(scene);
    stage.show();

    webEngine.getLoadWorker().stateProperty().addListener((obs, oldValue, newValue) -> { 
     System.out.println(webEngine.getLocation());
    });

当我尝试在装有windows操作系统的机器上执行此代码时，收到空白页面：

当我在macbook上执行相同的代码时，网站正在打开：

​

我使用的是java 10，我真的不知道出了什么问题。有没有人有同样的问题？你知道怎么解决这个问题吗？也许我可以用其他的组件来代替webview来做我的事情？

这不是你的问题的解决方案，但可能会把你引向正确的方向。看起来网站主体是使用script加载的。这个脚本依赖于我猜测的其他脚本。似乎没有其他脚本正在加载。

HTML上面还会显示加载的。它太长，无法添加。

here中的一些代码可帮助解决此问题。

我没有Java 10，我用的是Java 8。

Answer 2

我发现web view在mac os/ linux os上使用webkit引擎，在windows机器上使用IE引擎。在mac os上的WebView运行得很好，但在windows机器上却有问题。当我调查这个问题时，我发现这个IE引擎有问题。我可以访问几台安装了不同版本的IE 11的机器。在更新版本为11.0.85的计算机上，我无法打开此站点，但当我在更新版本为11.0.90的计算机上尝试时，该问题不再存在。因此，如果有人正在使用Windows操作系统，请尝试更新IE版本，也许可以解决问题。

Answer 3

我也有同样的问题，我想我找到了关键点:外部脚本/链接完整性失败。这不是平台浏览器问题，JavaFX (OpenJFK)依赖于嵌入式webkit引擎。

在windows JDK 8上，回归发生在版本40和版本172之间。它在Oracle JDK 9.0.4上运行良好。它不能在Oracle JDK 11上运行

问题类似于：Javafx - open login.microsoftonline.com page in webview component

=>更新的答案:实现覆盖微软表单内容并禁用完整性检查。这不是对webkit错误的修复，而是一个变通方法。
