Apache HttpClient 4.3에서 SSL 인증서 무시

Apache HttpClient 4.3에 대한 SSL 인증서 (모두 신뢰)를 무시하는 방법은 무엇입니까?

내가 찾은 모든 답변은 이전 버전을 처리하고 API가 변경되었습니다.

관련 :

• Apache HttpClient 4.0에서 SSL 인증서 오류를 무시하는 방법
• Apache HttpClient로 잘못된 SSL 인증서를 처리하는 방법은 무엇입니까?
• Spring을 사용하여 개발하는 동안 모든 인증서를 신뢰해야합니다.
• Java에서 SSL 인증서 오류 무시

편집하다:

• 테스트 목적으로 만 사용됩니다. 아이들, 집에서 (또는 프로덕션에서) 시도하지 마십시오.

아래 코드는 자체 서명 된 인증서를 신뢰하는 데 사용됩니다. 클라이언트를 만들 때 TrustSelfSignedStrategy 를 사용해야합니다 .

SSLContextBuilder builder = new SSLContextBuilder();
builder.loadTrustMaterial(null, new TrustSelfSignedStrategy());
SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(
        builder.build());
CloseableHttpClient httpclient = HttpClients.custom().setSSLSocketFactory(
        sslsf).build();

HttpGet httpGet = new HttpGet("https://some-server");
CloseableHttpResponse response = httpclient.execute(httpGet);
try {
    System.out.println(response.getStatusLine());
    HttpEntity entity = response.getEntity();
    EntityUtils.consume(entity);
} finally {
    response.close();
}

나는 SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER의도적으로 포함하지 않았습니다 . 핵심은 자체 서명 된 인증서로 테스트 할 수 있도록하여 인증 기관에서 적절한 인증서를 획득 할 필요가 없다는 것입니다. 올바른 호스트 이름을 사용하여 자체 서명 된 인증서를 쉽게 만들 수 있으므로 SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER플래그 를 추가하는 대신 그렇게하십시오 .

위의 PoolingHttpClientConnectionManager 절차가 작동하지 않는 경우 사용자 지정 SSLContext가 무시됩니다. PoolingHttpClientConnectionManager를 생성 할 때 생성자에서 socketFactoryRegistry를 전달해야합니다.

SSLContextBuilder builder = SSLContexts.custom();
builder.loadTrustMaterial(null, new TrustStrategy() {
    @Override
    public boolean isTrusted(X509Certificate[] chain, String authType)
            throws CertificateException {
        return true;
    }
});
SSLContext sslContext = builder.build();
SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(
        sslContext, new X509HostnameVerifier() {
            @Override
            public void verify(String host, SSLSocket ssl)
                    throws IOException {
            }

            @Override
            public void verify(String host, X509Certificate cert)
                    throws SSLException {
            }

            @Override
            public void verify(String host, String[] cns,
                    String[] subjectAlts) throws SSLException {
            }

            @Override
            public boolean verify(String s, SSLSession sslSession) {
                return true;
            }
        });

Registry<ConnectionSocketFactory> socketFactoryRegistry = RegistryBuilder
        .<ConnectionSocketFactory> create().register("https", sslsf)
        .build();

PoolingHttpClientConnectionManager cm = new PoolingHttpClientConnectionManager(
        socketFactoryRegistry);
CloseableHttpClient httpclient = HttpClients.custom()
        .setConnectionManager(cm).build();

@mavroprovato의 답변에 추가로 자체 서명이 아닌 모든 인증서를 신뢰하려면 (코드 스타일로)

builder.loadTrustMaterial(null, new TrustStrategy(){
    public boolean isTrusted(X509Certificate[] chain, String authType)
        throws CertificateException {
        return true;
    }
});

또는 (내 코드에서 직접 복사하여 붙여 넣기) :

import javax.net.ssl.SSLContext;
import org.apache.http.ssl.TrustStrategy;
import org.apache.http.ssl.SSLContexts;

// ...

        SSLContext sslContext = SSLContexts
                .custom()
                //FIXME to contain real trust store
                .loadTrustMaterial(new TrustStrategy() {
                    @Override
                    public boolean isTrusted(X509Certificate[] chain,
                        String authType) throws CertificateException {
                        return true;
                    }
                })
                .build();

호스트 이름 확인도 건너 뛰려면 다음을 설정해야합니다.

    CloseableHttpClient httpclient = HttpClients.custom().setSSLSocketFactory(
            sslsf).setSSLHostnameVerifier( NoopHostnameVerifier.INSTANCE).build();

게다가. (ALLOW_ALL_HOSTNAME_VERIFIER는 더 이상 사용되지 않습니다.)

필수 경고 : 실제로 이렇게해서는 안됩니다. 모든 인증서를 수락하는 것은 나쁜 일입니다. 그러나이를 수행하려는 드문 사용 사례가 있습니다.

이전에 제공된 코드에 대한 참고 사항으로 httpclient.execute ()에서 예외가 발생하더라도 응답을 닫고 싶을 것입니다.

CloseableHttpResponse response = null;
try {
    response = httpclient.execute(httpGet);
    System.out.println(response.getStatusLine());
    HttpEntity entity = response.getEntity();
    EntityUtils.consume(entity);
}
finally {
    if (response != null) {
        response.close();
    }
}

vasekt의 답변에 대한 작은 추가 사항 :

SocketFactoryRegistry와 함께 제공된 솔루션은 PoolingHttpClientConnectionManager를 사용할 때 작동합니다.

그러나 일반 http를 통한 연결은 더 이상 작동하지 않습니다. http 프로토콜에 대한 PlainConnectionSocketFactory를 추가로 추가하여 다시 작동하도록해야합니다.

Registry<ConnectionSocketFactory> socketFactoryRegistry = 
  RegistryBuilder.<ConnectionSocketFactory> create()
  .register("https", sslsf)
  .register("http", new PlainConnectionSocketFactory()).build();

다양한 옵션을 시도한 후 다음 구성이 http 및 https 모두에서 작동했습니다.

        SSLContextBuilder builder = new SSLContextBuilder();
        builder.loadTrustMaterial(null, new TrustSelfSignedStrategy());
        SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(builder.build(),SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);


        Registry<ConnectionSocketFactory> registry = RegistryBuilder.<ConnectionSocketFactory>create()
                .register("http", new PlainConnectionSocketFactory())
                .register("https", sslsf)
                .build();


        PoolingHttpClientConnectionManager cm = new PoolingHttpClientConnectionManager(registry);
        cm.setMaxTotal(2000);//max connection


        //System.setProperty("jsse.enableSNIExtension", "false"); //""
        CloseableHttpClient httpClient = HttpClients.custom()
                .setSSLSocketFactory(sslsf)
                .setConnectionManager(cm)
                .build();

http-client 4.3.3을 사용하고 있습니다.-

compile 'org.apache.httpcomponents:httpclient:4.3.3'

더 간단하고 짧은 작업 코드 :

우리는 HTTPClient 4.3.5를 사용하고 있으며 거의 ​​모든 솔루션이 stackoverflow에 존재하지만 아무것도 시도하지 않았습니다. 문제를 생각하고 파악한 후 완벽하게 작동하는 다음 코드가 나오면 HttpClient 인스턴스를 만들기 전에 추가합니다.

포스트 요청을 할 때 사용하는 방법 ...

SSLContextBuilder builder = new SSLContextBuilder();
    builder.loadTrustMaterial(null, new TrustStrategy() {
        @Override
        public boolean isTrusted(X509Certificate[] chain, String authType) throws CertificateException {
            return true;
        }
    });

    SSLConnectionSocketFactory sslSF = new SSLConnectionSocketFactory(builder.build(),
            SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);

    HttpClient httpClient = HttpClients.custom().setSSLSocketFactory(sslSF).build();
    HttpPost postRequest = new HttpPost(url);

계속해서 HttpPost 인스턴스를 일반 형식으로 호출하고 사용합니다.

다음은 "curl --insecure"에 해당하는 위 기술의 작동 증류입니다.

HttpClient getInsecureHttpClient() throws GeneralSecurityException {
    TrustStrategy trustStrategy = new TrustStrategy() {
        @Override
        public boolean isTrusted(X509Certificate[] chain, String authType) {
            return true;
        }
    };

    HostnameVerifier hostnameVerifier = new HostnameVerifier() {
        @Override
        public boolean verify(String hostname, SSLSession session) {
            return true;
        }
    };

    return HttpClients.custom()
            .setSSLSocketFactory(new SSLConnectionSocketFactory(
                    new SSLContextBuilder().loadTrustMaterial(trustStrategy).build(),
                    hostnameVerifier))
            .build();
}

http 클라이언트 4.5를 사용할 때 모든 호스트 이름 (테스트 목적)을 허용하려면 javasx.net.ssl.HostnameVerifier를 사용해야했습니다. 내가 한 일은 다음과 같습니다.

CloseableHttpClient httpClient = null;
    try {
        SSLContextBuilder sslContextBuilder = new SSLContextBuilder();
        sslContextBuilder.loadTrustMaterial(null, new TrustSelfSignedStrategy());

        HostnameVerifier hostnameVerifierAllowAll = new HostnameVerifier() 
            {
                public boolean verify(String hostname, SSLSession session) {
                    return true;
                }
            };

        SSLConnectionSocketFactory sslSocketFactory = new SSLConnectionSocketFactory(sslContextBuilder.build(), hostnameVerifierAllowAll);

        CredentialsProvider credsProvider = new BasicCredentialsProvider();
        credsProvider.setCredentials(
            new AuthScope("192.168.30.34", 8443),
            new UsernamePasswordCredentials("root", "password"));

        httpClient = HttpClients.custom()
            .setSSLSocketFactory(sslSocketFactory)
            .setDefaultCredentialsProvider(credsProvider)
            .build();

        HttpGet httpGet = new HttpGet("https://192.168.30.34:8443/axis/services/getStuff?firstResult=0&maxResults=1000");

        CloseableHttpResponse response = httpClient.execute(httpGet);

        int httpStatus = response.getStatusLine().getStatusCode();
        if (httpStatus >= 200 && httpStatus < 300) { [...]
        } else {
            throw new ClientProtocolException("Unexpected response status: " + httpStatus);
        }

    } catch (Exception ex) {
        ex.printStackTrace();
    }
    finally {
        try {
            httpClient.close();
        } catch (IOException ex) {
            logger.error("Error while closing the HTTP client: ", ex);
        }
    }

위에 PoolingHttpClientConnectionManager와 함께 Registry<ConnectionSocketFactory> socketFactoryRegistry = RegistryBuilder.<ConnectionSocketFactory> create().register("https", sslFactory).build(); 당신이 원하는 경우 비동기 HttpClient를 사용하여 PoolingNHttpClientConnectionManager다음과 유사 shoudl 코드를

SSLContextBuilder builder = SSLContexts.custom();
builder.loadTrustMaterial(null, new TrustStrategy() {
    @Override
    public boolean isTrusted(X509Certificate[] chain, String authType)
            throws CertificateException {
        return true;
    }
});
SSLContext sslContext = builder.build();
SchemeIOSessionStrategy sslioSessionStrategy = new SSLIOSessionStrategy(sslContext, 
                new HostnameVerifier(){
            @Override
            public boolean verify(String hostname, SSLSession session) {
                return true;// TODO as of now allow all hostnames

(나는 vasekt의 답변에 직접 의견을 추가했지만 평판 포인트가 충분하지 않습니다 (논리가 확실하지 않음)

어쨌든 ... 내가 말하고 싶은 것은 명시 적으로 PoolingConnection을 생성 / 요구하지 않더라도 연결을 얻지 못한다는 의미는 아닙니다.

원래 솔루션이 저에게 효과가 없었던 이유를 알아 내려고 미쳐 가고 있었지만 "내 케이스에 적용되지 않았기 때문에"바스 텍의 대답을 무시했습니다.-틀 렸습니다!

나는 낮을 때 내 스택 추적을 쳐다보고 있었고 그 중간에 PoolingConnection을 보았다. Bang-그의 추가와 성공에 지쳤습니다 !! (우리 데모는 내일이고 필사적이었습니다) :-)

SSL 인증 확인없이 HttpClient 인스턴스를 얻기 위해 다음 코드 스 니펫을 사용할 수 있습니다.

수중 음파 탐지기 보안 경고를 수정하기 위해 위의 @divbyzero에서 답변을 약간 수정했습니다.

CloseableHttpClient getInsecureHttpClient() throws GeneralSecurityException {
            TrustStrategy trustStrategy = (chain, authType) -> true;

            HostnameVerifier hostnameVerifier = (hostname, session) -> hostname.equalsIgnoreCase(session.getPeerHost());

            return HttpClients.custom()
                    .setSSLSocketFactory(new SSLConnectionSocketFactory(new SSLContextBuilder().loadTrustMaterial(trustStrategy).build(), hostnameVerifier))
                    .build();

처음에는 신뢰 전략을 사용하여 localhost를 비활성화 할 수 있었고 나중에 NoopHostnameVerifier를 추가했습니다. 이제 localhost와 모든 컴퓨터 이름 모두에서 작동합니다.

SSLContext sslContext = SSLContextBuilder.create().loadTrustMaterial(null, new TrustStrategy() {

            @Override
            public boolean isTrusted(X509Certificate[] chain, String authType) throws CertificateException {
                return true;
            }

        }).build();
        SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(
                sslContext, NoopHostnameVerifier.INSTANCE);
        CloseableHttpClient httpclient = HttpClients.custom().setSSLSocketFactory(sslsf).build();
