JavaFX WebView 无法加载某些站点 [英] JavaFX WebView can't load certain sites

问题描述

我正在尝试使用 JavaFX 的 WebView 加载此站点，但我得到的只是空白屏幕.WebView 在其他站点上运行良好；它在 ACID3 上获得 100/100 并加载其他 HTTPS 站点而没有任何问题.

I'm trying to use JavaFX's WebView to load this site, but all I get is a blank screen. The WebView is working perfectly fine on other sites; it gets 100/100 on ACID3 and loads other HTTPS sites without any problems whatsoever.

我也找不到该网站的任何特别错误.它有一个由适当的 CA 签署的适当的、未过期的证书，并且 SSL 实验室报告 B 级.我尝试了所有主流浏览器，但没有报告任何证书或 SSL 相关问题；该网站在所有这些方面都表现良好.

I can't find anything particularly wrong with the site either. It has a proper, non-expired certificate signed by proper CA, and SSL Labs report a B grade. I tried all the major browsers on it and none report any certificate or SSL related issues; the site renders fine on all of them.

任何帮助将不胜感激.即使是简单的是的，该网站对我来说也坏了"或这里没有问题"也会有很大帮助.

Any help would be greatly appreciated. Even a simple "yeah the site's broken for me too" or "no problems here" would help a lot.

我在 Windows 8.1 64 位上使用 Java SDK 1.8.0_45-b14.

推荐答案

原因是java.lang.Throwable: SSL握手失败

一种解决方案可以是:从这篇文章https://stackoverflow.com/a/5671038/1032167:

One solution can be: from this post https://stackoverflow.com/a/5671038/1032167:

     TrustManager trm = new X509TrustManager() {
        public X509Certificate[] getAcceptedIssuers() {return null;}
        public void checkClientTrusted(X509Certificate[] certs, String authType) {}
        public void checkServerTrusted(X509Certificate[] certs, String authType) {}
    };

    SSLContext sc = SSLContext.getInstance("SSL");
    sc.init(null, new TrustManager[] { trm }, null);
    HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());

也有帖子，大概是类似的情况:JavaFx Webview JDK 8 无法加载自签名证书

There is also post, probably about similar case: JavaFx Webview JDK 8 can not load self signed certificate

我怎么知道是SSL握手失败

webView.getEngine().getLoadWorker().stateProperty().addListener(
            new ChangeListener<Worker.State>() {
                public void changed(ObservableValue ov, 
                      Worker.State oldState, Worker.State newState) {
            System.out.println(webView.getEngine().getLoadWorker().exceptionProperty());
             ...

同时添加 add -Djavax.net.debug=all 到 VMOption 显示

also adding add -Djavax.net.debug=all to VMOption shows

URL-Loader-1，处理异常:javax.net.ssl.SSLHandshakeException:

URL-Loader-1, handling exception: javax.net.ssl.SSLHandshakeException:

sun.security.validator.ValidatorException:PKIX 路径构建失败:
