Comment puis-je contourner les erreurs de certificat SSL non valides avec Apache HttpClient 4.0?

Trop de publicités?Vous devez créer un SSLContext avec votre propre TrustManager et créer un schéma HTTPS en utilisant ce contexte. Voici le code,
SSLContext sslContext = SSLContext.getInstance("SSL");
// set up a TrustManager that trusts everything
sslContext.init(null, new TrustManager[] { new X509TrustManager() {
public X509Certificate[] getAcceptedIssuers() {
System.out.println("getAcceptedIssuers =============");
return null;
}
public void checkClientTrusted(X509Certificate[] certs,
String authType) {
System.out.println("checkClientTrusted =============");
}
public void checkServerTrusted(X509Certificate[] certs,
String authType) {
System.out.println("checkServerTrusted =============");
}
} }, new SecureRandom());
SSLSocketFactory sf = new SSLSocketFactory(sslContext);
Scheme httpsScheme = new Scheme("https", 443, sf);
SchemeRegistry schemeRegistry = new SchemeRegistry();
schemeRegistry.register(httpsScheme);
// apache HttpClient version >4.2 should use BasicClientConnectionManager
ClientConnectionManager cm = new SingleClientConnManager(schemeRegistry);
HttpClient httpClient = new DefaultHttpClient(cm);
Pour mémoire, il existe un moyen beaucoup plus simple de réaliser la même chose avec HttpClient 4.1
SSLSocketFactory sslsf = new SSLSocketFactory(new TrustStrategy() {
public boolean isTrusted(
final X509Certificate[] chain, String authType) throws CertificateException {
// Oh, I am easy...
return true;
}
});
Si tout ce que vous voulez faire, c'est vous débarrasser des erreurs de nom d'hôte non valides, vous pouvez simplement le faire:
HttpClient httpClient = new DefaultHttpClient();
SSLSocketFactory sf = (SSLSocketFactory)httpClient.getConnectionManager()
.getSchemeRegistry().getScheme("https").getSocketFactory();
sf.setHostnameVerifier(new AllowAllHostnameVerifier());
Voici comment je l'ai fait -
- Créer ma propre MockSSLSocketFactory (classe ci-dessous)
- Utilisez-le pour initialiser DefaultHttpClient. Les paramètres de proxy doivent être fournis si un proxy est utilisé.
Initialisation de DefaultHTTPClient -
SchemeRegistry schemeRegistry = new SchemeRegistry();
schemeRegistry.register(new Scheme("http", 80, PlainSocketFactory.getSocketFactory()));
schemeRegistry.register(new Scheme("https", 443, new MockSSLSocketFactory()));
ClientConnectionManager cm = new SingleClientConnManager(schemeRegistry);
DefaultHttpClient httpclient = new DefaultHttpClient(cm);
Mock SSL Factory -
public class MockSSLSocketFactory extends SSLSocketFactory {
public MockSSLSocketFactory() throws NoSuchAlgorithmException, KeyManagementException, KeyStoreException, UnrecoverableKeyException {
super(trustStrategy, hostnameVerifier);
}
private static final X509HostnameVerifier hostnameVerifier = new X509HostnameVerifier() {
@Override
public void verify(String host, SSLSocket ssl) throws IOException {
// Do nothing
}
@Override
public void verify(String host, X509Certificate cert) throws SSLException {
//Do nothing
}
@Override
public void verify(String host, String[] cns, String[] subjectAlts) throws SSLException {
//Do nothing
}
@Override
public boolean verify(String s, SSLSession sslSession) {
return true;
}
};
private static final TrustStrategy trustStrategy = new TrustStrategy() {
@Override
public boolean isTrusted(X509Certificate[] chain, String authType) throws CertificateException {
return true;
}
};
}
Si derrière un proxy, besoin de le faire -
HttpParams params = new BasicHttpParams();
params.setParameter(AuthPNames.PROXY_AUTH_PREF, getClientAuthPrefs());
DefaultHttpClient httpclient = new DefaultHttpClient(cm, params);
httpclient.getCredentialsProvider().setCredentials(
new AuthScope(proxyHost, proxyPort),
new UsernamePasswordCredentials(proxyUser, proxyPass));
