Wenn Sie zusätzlich zur Antwort von @mavroprovato allen Zertifikaten vertrauen möchten, anstatt nur selbstsigniert zu sein, tun Sie dies (im Stil Ihres Codes).
builder.loadTrustMaterial(null, new TrustStrategy(){
public boolean isTrusted(X509Certificate[] chain, String authType)
throws CertificateException {
return true;
}
});
oder (direktes Kopieren und Einfügen aus meinem eigenen Code):
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();
Und wenn Sie auch die Überprüfung des Hostnamens überspringen möchten, müssen Sie festlegen
CloseableHttpClient httpclient = HttpClients.custom().setSSLSocketFactory(
sslsf).setSSLHostnameVerifier( NoopHostnameVerifier.INSTANCE).build();
auch. (ALLOW_ALL_HOSTNAME_VERIFIER ist veraltet).
Obligatorische Warnung: Sie sollten dies nicht wirklich tun. Das Akzeptieren aller Zertifikate ist eine schlechte Sache. Es gibt jedoch einige seltene Anwendungsfälle, in denen Sie dies tun möchten.
Als Hinweis auf den zuvor angegebenen Code möchten Sie die Antwort auch dann schließen, wenn httpclient.execute () eine Ausnahme auslöst
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();
}
}
