[java] SSL 핸드 셰이크 경고 : Java 1.7.0으로 업그레이드 한 후 unrecognized_name 오류

유용해야합니다. Apache HttpClient 4.4에서 SNI 오류를 다시 시도하려면 가장 쉬운 방법입니다 ( HTTPCLIENT-1522 참조 ).

public class SniHttpClientConnectionOperator extends DefaultHttpClientConnectionOperator {

    public SniHttpClientConnectionOperator(Lookup<ConnectionSocketFactory> socketFactoryRegistry) {
        super(socketFactoryRegistry, null, null);
    }

    @Override
    public void connect(
            final ManagedHttpClientConnection conn,
            final HttpHost host,
            final InetSocketAddress localAddress,
            final int connectTimeout,
            final SocketConfig socketConfig,
            final HttpContext context) throws IOException {
        try {
            super.connect(conn, host, localAddress, connectTimeout, socketConfig, context);
        } catch (SSLProtocolException e) {
            Boolean enableSniValue = (Boolean) context.getAttribute(SniSSLSocketFactory.ENABLE_SNI);
            boolean enableSni = enableSniValue == null || enableSniValue;
            if (enableSni && e.getMessage() != null && e.getMessage().equals("handshake alert:  unrecognized_name")) {
                TimesLoggers.httpworker.warn("Server received saw wrong SNI host, retrying without SNI");
                context.setAttribute(SniSSLSocketFactory.ENABLE_SNI, false);
                super.connect(conn, host, localAddress, connectTimeout, socketConfig, context);
            } else {
                throw e;
            }
        }
    }
}

public class SniSSLSocketFactory extends SSLConnectionSocketFactory {

    public static final String ENABLE_SNI = "__enable_sni__";

    /*
     * Implement any constructor you need for your particular application -
     * SSLConnectionSocketFactory has many variants
     */
    public SniSSLSocketFactory(final SSLContext sslContext, final HostnameVerifier verifier) {
        super(sslContext, verifier);
    }

    @Override
    public Socket createLayeredSocket(
            final Socket socket,
            final String target,
            final int port,
            final HttpContext context) throws IOException {
        Boolean enableSniValue = (Boolean) context.getAttribute(ENABLE_SNI);
        boolean enableSni = enableSniValue == null || enableSniValue;
        return super.createLayeredSocket(socket, enableSni ? target : "", port, context);
    }
}

cm = new PoolingHttpClientConnectionManager(new SniHttpClientConnectionOperator(socketFactoryRegistry), null, -1, TimeUnit.MILLISECONDS);
