getforobject - Acceda al servicio de descanso Https usando Spring RestTemplate

resttemplate getforobject headers

Question

¿Alguien puede proporcionarme un ejemplo de código para acceder a la URL del servicio de descanso asegurada con https usando la plantilla de descanso de primavera?

Tengo el certificado, nombre de usuario y contraseña. La autenticación básica se utiliza en el lado del servidor y quiero crear un cliente que pueda conectarse a ese servidor utilizando el certificado, el nombre de usuario y la contraseña proporcionados (si es necesario).

Aquí está lo que terminé con el problema similar. La idea es la misma que en la respuesta de @ Avi, pero también quería evitar la estática "System.setProperty (" https.protocols "," TLSv1 ");", para que los ajustes no afecten al sistema. Inspirado por una respuesta de aquí http://www.coderanch.com/t/637177/Security/Disabling-handshake-message-Java

        }

Answer 2

Aquí hay un código que le dará la idea general.

ClientHttpRequestFactory crear un ClientHttpRequestFactory personalizado para poder confiar en el certificado. Se parece a esto:

final ClientHttpRequestFactory clientHttpRequestFactory =
        new MyCustomClientHttpRequestFactory(org.apache.http.conn.ssl.SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER, serverInfo);
    restTemplate.setRequestFactory(clientHttpRequestFactory);

Esta es la implementación de MyCustomClientHttpRequestFactory :

public class MyCustomClientHttpRequestFactory  extends SimpleClientHttpRequestFactory {

private final HostnameVerifier hostNameVerifier;
private final ServerInfo serverInfo;

public MyCustomClientHttpRequestFactory (final HostnameVerifier hostNameVerifier,
    final ServerInfo serverInfo) {
    this.hostNameVerifier = hostNameVerifier;
    this.serverInfo = serverInfo;
}

@Override
protected void prepareConnection(final HttpURLConnection connection, final String httpMethod)
    throws IOException {
    if (connection instanceof HttpsURLConnection) {
        ((HttpsURLConnection) connection).setHostnameVerifier(hostNameVerifier);
        ((HttpsURLConnection) connection).setSSLSocketFactory(initSSLContext()
            .getSocketFactory());
    }
    super.prepareConnection(connection, httpMethod);
}

private SSLContext initSSLContext() {
    try {
        System.setProperty("https.protocols", "TLSv1");

        // Set ssl trust manager. Verify against our server thumbprint
        final SSLContext ctx = SSLContext.getInstance("TLSv1");
        final SslThumbprintVerifier verifier = new SslThumbprintVerifier(serverInfo);
        final ThumbprintTrustManager thumbPrintTrustManager =
            new ThumbprintTrustManager(null, verifier);
        ctx.init(null, new TrustManager[] { thumbPrintTrustManager }, null);
        return ctx;
    } catch (final Exception ex) {
        LOGGER.error(
            "An exception was thrown while trying to initialize HTTP security manager.", ex);
        return null;
    }
}

En este caso, mi objeto serverInfo contiene la huella digital del servidor. TrustManager implementar la interfaz de TrustManager para obtener el SslThumbprintVerifier o cualquier otro método que desee para verificar su certificado (también puede decidir devolver siempre el valor true ).

El valor org.apache.http.conn.ssl.SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER permite todos los nombres de host. Si necesita verificar el nombre del host, deberá implementarlo de manera diferente.

No estoy seguro sobre el usuario y la contraseña y cómo lo implementó. A menudo, es necesario agregar un encabezado a la restTemplate denominada Authorization con un valor similar al siguiente: Base: <encoded user+password> . El user+password debe estar codificado en Base64 .

Answer 3

Esta es una solución sin clase ni método en desuso: (Java 8 aprobado)

CloseableHttpClient httpClient = HttpClients.custom().setSSLHostnameVerifier(new NoopHostnameVerifier()).build();

HttpComponentsClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory();
requestFactory.setHttpClient(httpClient);

RestTemplate restTemplate = new RestTemplate(requestFactory);

Answer 4

Un punto de mi parte. Utilicé una autenticación cert mutua con microservicios de arranque por resorte. Lo siguiente está funcionando para mí, los puntos clave aquí son keyManagerFactory.init (...) y sslcontext.init (keyManagerFactory.getKeyManagers (), null, nuevas líneas de código SecureRandom ()) sin ellas, al menos para mí, las cosas no funcionaron. Los certificados son empaquetados por PKCS12.

@Value("${server.ssl.key-store-password}")
private String keyStorePassword;
@Value("${server.ssl.key-store-type}")
private String keyStoreType;
@Value("${server.ssl.key-store}")
private Resource resource;

private RestTemplate getRestTemplate() throws Exception {
    return new RestTemplate(clientHttpRequestFactory());
}

private ClientHttpRequestFactory clientHttpRequestFactory() throws Exception {
    return new HttpComponentsClientHttpRequestFactory(httpClient());
}

private HttpClient httpClient() throws Exception {

    KeyManagerFactory keyManagerFactory = KeyManagerFactory.getInstance("SunX509");
    KeyStore trustStore = KeyStore.getInstance(keyStoreType);

    if (resource.exists()) {
        InputStream inputStream = resource.getInputStream();

        try {
            if (inputStream != null) {
                trustStore.load(inputStream, keyStorePassword.toCharArray());
                keyManagerFactory.init(trustStore, keyStorePassword.toCharArray());
            }
        } finally {
            if (inputStream != null) {
                inputStream.close();
            }
        }
    } else {
        throw new RuntimeException("Cannot find resource: " + resource.getFilename());
    }

    SSLContext sslcontext = SSLContexts.custom().loadTrustMaterial(trustStore, new TrustSelfSignedStrategy()).build();
    sslcontext.init(keyManagerFactory.getKeyManagers(), null, new SecureRandom());
    SSLConnectionSocketFactory sslConnectionSocketFactory =
            new SSLConnectionSocketFactory(sslcontext, new String[]{"TLSv1.2"}, null, getDefaultHostnameVerifier());

    return HttpClients.custom().setSSLSocketFactory(sslConnectionSocketFactory).build();
}

Answer 5

    KeyStore keyStore = KeyStore.getInstance(KeyStore.getDefaultType());
    keyStore.load(new FileInputStream(new File(keyStoreFile)), keyStorePassword.toCharArray());

    SSLConnectionSocketFactory socketFactory = new SSLConnectionSocketFactory(
            new SSLContextBuilder()
                    .loadTrustMaterial(null, new TrustSelfSignedStrategy())
                    .loadKeyMaterial(keyStore, keyStorePassword.toCharArray())
                    .build(),
            NoopHostnameVerifier.INSTANCE);

    HttpClient httpClient = HttpClients.custom().setSSLSocketFactory(socketFactory).build();

    ClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory(httpClient);
    RestTemplate restTemplate = new RestTemplate(requestFactory);
    MyRecord record = restTemplate.getForObject(uri, MyRecord.class);
    LOG.debug(record.toString());
