使用端口 3000 加载页面后，服务器拒绝连接和未知错误 javafx.web

Question

加载http://127.0.0.1:3000时出现此错误：

在端口 3000 上加载页面时也可能出现“连接被服务器拒绝”错误，但本地页面不会：

我试过这个但没有成功：

HostnameVerifier allHostsValid = new HostnameVerifier() {
            public boolean verify(String hostname, SSLSession session) {
                return true;
            }
        };
        HttpsURLConnection.setDefaultHostnameVerifier(allHostsValid);

它：

TrustManager[] trustAllCerts = new TrustManager[] {
                new X509TrustManager() {
                    public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                        return null;
                    }
                    public void checkClientTrusted(
                            java.security.cert.X509Certificate[] certs, String authType) {
                    }
                    public void checkServerTrusted(
                            java.security.cert.X509Certificate[] certs, String authType) {
                    }
                }
        };

        try {
            SSLContext sc = SSLContext.getInstance("SSL");
            sc.init(null, trustAllCerts, new java.security.SecureRandom());
            HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
        } catch (GeneralSecurityException e) {
            System.out.println("SSL trust error: " + e.getMessage());
        }

错误与状态 Worker.State.FAILED 一起出现。 它可以连接什么？

这对我有用，页面现在可以运行，但仍然效果不佳。 端口 3000 上的一些页面打开，然后重定向到 index.html，这是不应该发生的。：

 System.setProperty("http.proxyHost","my.site.com"); System.setProperty("http.proxyPort","3000");
