使用 TLS 端点验证时主题备用名称为空
Subject Alternate Name is null when using TLS endpoint validation
上下文
我正在尝试创建一个 SSLEngine 来验证主题备用名称对于服务器返回的证书是否正确。我知道 java 不会自动执行此操作，必须要求执行此操作。我按如下方式设置了我的 SSLEngine
//this keystore will provide client certificates, an optional part of TLS to identify the client.
KeyStore personalKS = KeyStore.getInstance( "Windows-MY" ); //$NON-NLS-1$
personalKS.load( null, null );
KeyManagerFactory keyManagerFactory = KeyManagerFactory.getInstance( KeyManagerFactory.getDefaultAlgorithm() );
keyManagerFactory.init( personalKS, null );
SSLContext context = SSLContext.getInstance( "TLSv1.3" );
SSLParameters sslParams = new SSLParameters();
sslParams.setEndpointIdentificationAlgorithm("HTTPS");
context.init( keyManagerFactory.getKeyManagers(), null, null );
SSLEngine sslEngine = context.createSSLEngine();
sslEngine.setSSLParameters( sslParams );
return sslEngine;
没有 sslParams.setEndpointIdentificationAlgorithm("HTTPS"); 行，任何有效签名证书的连接都会成功（即使其主题备用名称不正确）。
但是，一旦我添加该行，我就会遇到异常

有趣的是，调试 HostNameChecker#match 中发生的事情表明 X509Certificate 没有任何主题备用名称。但它的 toString 表示确实如此。
这些是我创建的内部网络证书，由本地根 CA 签名，所以很可能我创建的证书有误
问题
我应该如何设置 sslEngine 来验证域名和证书验证？为什么我会收到此空指针异常？
看起来问题是在主机名检查器中，“预期名称”是由我提供的，而不是我根据我正在连接的 URL 想象的那样。
我创建 SSL 引擎的正确方法如下
SSLEngine sslEngine = context.createSSLEngine(hostname, port);
我的代码知道我希望与之通信的主机和端口（幸运的是，在我的例子中我这样做了）
上下文
我正在尝试创建一个 SSLEngine 来验证主题备用名称对于服务器返回的证书是否正确。我知道 java 不会自动执行此操作，必须要求执行此操作。我按如下方式设置了我的 SSLEngine
//this keystore will provide client certificates, an optional part of TLS to identify the client.
KeyStore personalKS = KeyStore.getInstance( "Windows-MY" ); //$NON-NLS-1$
personalKS.load( null, null );
KeyManagerFactory keyManagerFactory = KeyManagerFactory.getInstance( KeyManagerFactory.getDefaultAlgorithm() );
keyManagerFactory.init( personalKS, null );
SSLContext context = SSLContext.getInstance( "TLSv1.3" );
SSLParameters sslParams = new SSLParameters();
sslParams.setEndpointIdentificationAlgorithm("HTTPS");
context.init( keyManagerFactory.getKeyManagers(), null, null );
SSLEngine sslEngine = context.createSSLEngine();
sslEngine.setSSLParameters( sslParams );
return sslEngine;
没有 sslParams.setEndpointIdentificationAlgorithm("HTTPS"); 行，任何有效签名证书的连接都会成功（即使其主题备用名称不正确）。
但是，一旦我添加该行，我就会遇到异常

有趣的是，调试 HostNameChecker#match 中发生的事情表明 X509Certificate 没有任何主题备用名称。但它的 toString 表示确实如此。
这些是我创建的内部网络证书，由本地根 CA 签名，所以很可能我创建的证书有误
问题
我应该如何设置 sslEngine 来验证域名和证书验证？为什么我会收到此空指针异常？
看起来问题是在主机名检查器中，“预期名称”是由我提供的，而不是我根据我正在连接的 URL 想象的那样。
我创建 SSL 引擎的正确方法如下
SSLEngine sslEngine = context.createSSLEngine(hostname, port);
我的代码知道我希望与之通信的主机和端口（幸运的是，在我的例子中我这样做了）
