java - 在识别和修复 SSLPeerUnverifiedException 方面需要帮助

Question

我正在尝试为默认和自定义 keystore 向 TLS 服务器发送一个帖子。在执行执行时获得 CloseableHttpClient 实例后

CloseableHttpResponse response1 = client.execute(postMethod);

这是给我 javax.net.ssl.SSLPeerUnverifiedException: Certificate for <hostname.domain.com> doesn't match any of the subject alternative names: []上面一行的异常。

下面是我准备客户端实例的类

public class ClientelUtil {

    public static CloseableHttpClient getHttpClient(String scheme,SSLContext sslContext) {
        HttpClientBuilder clientBuilder = HttpClients.custom();
        CloseableHttpClient client = null;
        if ("https".equalsIgnoreCase(scheme)) {
            SSLConnectionSocketFactory sFactory = new SSLConnectionSocketFactory(sslContext);
            final Registry<ConnectionSocketFactory> registry = RegistryBuilder.<ConnectionSocketFactory>create()
                    .register("http", new PlainConnectionSocketFactory()).register("https", sFactory).build();

            final PoolingHttpClientConnectionManager cm = new PoolingHttpClientConnectionManager(registry);

            clientBuilder = HttpClients.custom().setSSLSocketFactory(sFactory)
                    .setSSLHostnameVerifier(NoopHostnameVerifier.INSTANCE)
                    .setConnectionManager(cm);
        }
        client = clientBuilder.build();
        return client;

    }

    public static CloseableHttpClient getHttpClient(String scheme) {
        return getHttpClient(scheme, getSSLContext());

    }

    public static CloseableHttpClient getHttpClientWithoutTLSValidation(String scheme) {
        return getHttpClient(scheme, getSSLContextWithoutValidation());

    }

    public static SSLContext getSSLContextWithoutValidation() {
        SSLContext sslContext=null;
        try {
            sslContext = new SSLContextBuilder().loadTrustMaterial(null, new TrustStrategy() {
                public boolean isTrusted(X509Certificate[] arg0, String arg1) throws CertificateException {
                    return true;
                }
            }).build();
        } catch (KeyManagementException | NoSuchAlgorithmException | KeyStoreException e) {
            e.printStackTrace();
        }
        return sslContext;
    }

    public static SSLContext getSSLContext() {
        SSLContext sslContext=null;
        try {
            JKSInfo jksInfo = JKSUtil.getTrustStoreInfo();
            sslContext = HttpSSLUtil.getSSLContext(jksInfo.getJksPath(), jksInfo.getJksPassword());
        } catch (HttpSSLException e) {
            e.printStackTrace();
        }
        return sslContext;
    }

}

这是我在我的程序中使用上述类的地方

public String post(String host,int port,Map<String,String> data) {

    CloseableHttpClient client = null;
    String response = null;
    String protocol = HTTP;
    try{
        if( isServerSSLEnabled() ){ //returns a boolean tru or false. In this case it is true
            protocol = HTTPS;
        }
        client = ClientelUtil.getHttpClient(protocol);
        //RequestConfig requestConfig = RequestConfig.custom().setCircularRedirectsAllowed(true).build();
        URIBuilder builder = new URIBuilder()
                    .setScheme(protocol)
                    .setHost(host).setPort(port)
                    .setPath(CONNECT_URI);

        URI uri = builder.build();

        HttpPost postMethod = new HttpPost(uri);
        //postMethod.setConfig(requestConfig);
        logger.debug("Sending request on host [" + host +"], port ["+ port+"], Protocol ["+ protocol + "] connectURI ["+CONNECT_URI+"]");


        addRequestHeaders(postMethod);
        ArrayList<NameValuePair> postParameters = new ArrayList<NameValuePair>();
        try {
            for(Map.Entry<String,String> entry : data.entrySet()) {
                postParameters.add(new BasicNameValuePair(entry.getKey(),entry.getValue()));
            }
            postMethod.setEntity(new UrlEncodedFormEntity(postParameters));
            CloseableHttpResponse response1 = client.execute(postMethod);       // <-- SSLPeerUnverifiedException at this point
            response = EntityUtils.toString(response1.getEntity());
        } catch (IOException e) {
            logger.error("Error while running the scenario on node host [" + host+"]",e);
        } finally{
            postMethod.releaseConnection();
        }
    } catch (URISyntaxException e1) {
        e1.printStackTrace();
    }finally {
        if(client!=null)
            try {
                client.close();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
    }
    return response;
}

我为此使用 apache http client 4.5，请帮助确定这里有什么问题。

也是CN=FQDN在 getSSLContext 中使用的 keystore 中需要我使用的方法 NoopHostnameVerifier.INSTANCE创建HttpClientBuilder ？

谢谢

更新

我用 Common Name (e.g. server FQDN or YOUR name) []: 创建了一个新的信任库文件作为我的主机名，之后上面的代码开始工作(现在我使用 hostname 来访问我的服务器代码，而不是上面我的问题中提到的 hostname.domain.com )。

现在我的问题是，如果 CN | Common Name不存在于信任库文件中，可以使用上面代码中的一些修改来验证吗？请建议。再次感谢。

更新

发布完整的堆栈跟踪。在主机名 validator 的情况下返回 true 也是一个好习惯，这样它就可以忽略主机名验证并在生产中没有提供 CN 或 SAN 的情况下工作(请让我知道何时可以使用，否则)？

Answer 1

这是服务器证书或 DNS 映射的问题，而不是您的代码。您连接的服务器名称不在它提供的 SSL 证书中。

您不应寻找不安全的解决方法，例如空 HTTPS 主机名验证程序。
