Comment ignorer la création du chemin PKIX a échoué: Sun.security.provider.certpath.SunCertPathBuilderException?

J'ai eu l'exception suivante lorsque j'essaie de poster une demande sur un serveur http:

Voici le code que j'ai utilisé

URL url = new URL(
        "https://www.abc.com");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();

conn.setRequestMethod("GET");

conn.setDoOutput(true);

DataOutputStream wr = new DataOutputStream(conn.getOutputStream());
// wr.writeBytes(params);
wr.flush();
wr.close();

BufferedReader br = new BufferedReader(new InputStreamReader(
        conn.getInputStream()));
String line = null;
while ((line = br.readLine()) != null) {
    System.out.println(line);
}

Voici l'exception:

Le serveur ne m'appartient pas. Y a-t-il un moyen d'ignorer cette exception?

Si vous souhaitez ignorer le certificat dans son ensemble, jetez un coup d'œil à la réponse suivante: Ignorez le certificat SSL auto-signé à l'aide du client Jersey

Bien que cela rende votre application vulnérable aux attaques de l'homme du milieu.

Ou bien, essayez d’ajouter le certificat à votre magasin Java en tant que certificat approuvé. Ce site peut être utile. http://blog.icodejava.com/tag/get-public-key-of-ssl-certificate-in-Java/

Voici un autre fil montrant comment ajouter un certificat à votre magasin. connexion SSL Java, ajouter un certificat de serveur au magasin de clés par programme

La clé est:

KeyStore.Entry newEntry = new KeyStore.TrustedCertificateEntry(someCert);
ks.setEntry("someAlias", newEntry, null);

J'ai utilisé le code ci-dessous pour remplacer la vérification SSL dans mon projet et cela a fonctionné pour moi.

package com.beingjavaguys.testftp;

import Java.io.InputStreamReader;
import Java.io.Reader;
import Java.net.URL;
import Java.net.URLConnection;

import javax.net.ssl.HostnameVerifier;
import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLSession;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;
import Java.security.cert.X509Certificate;

/**
 * Fix for Exception in thread "main" javax.net.ssl.SSLHandshakeException:
 * Sun.security.validator.ValidatorException: PKIX path building failed:
 * Sun.security.provider.certpath.SunCertPathBuilderException: unable to find
 * valid certification path to requested target
 */
public class ConnectToHttpsUrl {
    public static void main(String[] args) throws Exception {
        /* Start of Fix */
        TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() {
            public Java.security.cert.X509Certificate[] getAcceptedIssuers() { return null; }
            public void checkClientTrusted(X509Certificate[] certs, String authType) { }
            public void checkServerTrusted(X509Certificate[] certs, String authType) { }

        } };

        SSLContext sc = SSLContext.getInstance("SSL");
        sc.init(null, trustAllCerts, new Java.security.SecureRandom());
        HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());

        // Create all-trusting Host name verifier
        HostnameVerifier allHostsValid = new HostnameVerifier() {
            public boolean verify(String hostname, SSLSession session) { return true; }
        };
        // Install the all-trusting Host verifier
        HttpsURLConnection.setDefaultHostnameVerifier(allHostsValid);
        /* End of the fix*/

        URL url = new URL("https://nameofthesecuredurl.com");
        URLConnection con = url.openConnection();
        Reader reader = new InputStreamReader(con.getInputStream());
        while (true) {
            int ch = reader.read();
            if (ch == -1) 
                break;
            System.out.print((char) ch);
        }
    }
}

Définissez la propriété validateTLSCertificates sur false pour votre commande JSoup .

Jsoup.connect("https://google.com/").validateTLSCertificates(false).get();

FWIW, sur Ubuntu 10.04.2 LTS, l’installation des paquetages ca-certificates-Java et ca-certificates a résolu ce problème.

La même erreur s'est produite lors de l'exécution du test simple ci-dessous, spring-boot + RestAssured.

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import static com.jayway.restassured.RestAssured.when;
import static org.Apache.http.HttpStatus.SC_OK;

@RunWith(SpringJUnit4ClassRunner.class)
public class GeneratorTest {

@Test
public void generatorEndPoint() {
    when().get("https://bal-bla-bla-bla.com/generators")
            .then().statusCode(SC_OK);
    }
}

La solution simple dans mon cas est d'ajouter 'useRelaxedHTTPSValidations ()'

RestAssured.useRelaxedHTTPSValidation();

Ensuite, le test ressemble à

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import static com.jayway.restassured.RestAssured.when;
import static org.Apache.http.HttpStatus.SC_OK;

@RunWith(SpringJUnit4ClassRunner.class)
public class GeneratorTest {

@Before
public void setUp() {
   RestAssured.useRelaxedHTTPSValidation();
}


@Test
public void generatorEndPoint() {
    when().get("https://bal-bla-bla-bla.com/generators")
            .then().statusCode(SC_OK);
    }
}

Si vous utilisez CloudFoundry, vous devez explicitement insérer le fichier jar avec le fichier de clés contenant le certificat.
