java - 使用 HTTPS 的基本身份验证

Question

我目前正在尝试使用 HTTP 和 HTTPS 访问 URL。我尝试访问的 URL 需要基本身份验证。使用 HTTP 可以正常工作，但使用 HTTPS 则不行。我不确定是否需要使用 HTTPS 添加不同的内容。该 URL 应该向我返回键值格式的文本，我可以将其加载到 Properties 对象中。

这是我到目前为止尝试过的代码。

if (cpUrl.getProtocol().equals("https")) {
                        out.println("https", 0);
                        HttpsURLConnection connection = (HttpsURLConnection) cpUrl.openConnection();

                        TrustManager[] trustAllCerts = new TrustManager[] { new  BusinessIntelligenceX509TrustManager() };
                        SSLContext sc;

                        try {
                            sc = SSLContext.getInstance("SSL");
                        }
                        catch (NoSuchAlgorithmException noSuchAlgorithmException) {
                            return;
                        }

                        HostnameVerifier hv = new BusinessIntelligenceHostnameVerifier();

                        try {
                            sc.init(null, trustAllCerts, new java.security.SecureRandom());
                        }
                        catch (KeyManagementException keyManagementException) {

                            return;
                        }

                        HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
                        HttpsURLConnection.setDefaultHostnameVerifier(hv);

                        connection.setDoInput(true);
                        connection.setRequestProperty("Authorization", "Basic " + encode);

                        connection.setRequestMethod("POST");
                        connection.connect();
                        stream = connection.getInputStream();
                        Properties properties = new Properties();
                        properties.load(stream);

                    }

这是证书类

   //HTTPS CERTIFICATE CLASSES
    class BusinessIntelligenceHostnameVerifier implements HostnameVerifier {

        public boolean verify(String arg0, SSLSession arg1) {
            return true;
        }

    }

    class BusinessIntelligenceX509TrustManager implements X509TrustManager {

        public java.security.cert.X509Certificate[] getAcceptedIssuers() {
            return null;
        }

        public void checkClientTrusted(java.security.cert.X509Certificate[] certs, String authType) {
            // no-op
        }

        public void checkServerTrusted(java.security.cert.X509Certificate[] certs, String authType) {
            // no-op
        }

    }

当我删除所有证书代码(以及证书代码)时的错误消息:

Answer 1

问题似乎出在连接打开之前，SSLContext 和 HostNameVerifier 实例针对连接进行了更改。这是不可能的，因为 SSL/TLS 握手甚至发生在从 InputStream 读取连接内容之前。

换句话说，下面一行

HttpsURLConnection connection = (HttpsURLConnection) cpUrl.openConnection();

应该仅在 SSLContext 和 HostNameVerifier 实例已注册到 HttpsURLConnection 类后执行。

HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
HttpsURLConnection.setDefaultHostnameVerifier(hv);

修复此序列应该可以解决问题，因为现在将使用新参数进行握手。
