证书中的主机名不匹配？

Question

我尝试使用自签名证书连接到服务器.我使用此代码接受所有证书.

public class CertificateAcceptor {

    public void initializeTrustManager() {
        try {
            SSLContext context = SSLContext.getInstance("SSL");
            context.init(null, createTrustManager(), new SecureRandom());
            HttpsURLConnection.setDefaultSSLSocketFactory(context.getSocketFactory());

        } catch (NoSuchAlgorithmException e) {
            e.printStackTrace();
        } catch (KeyManagementException e) {
            e.printStackTrace();
        }
    }

    private TrustManager[] createTrustManager() {

    TrustManager[] trustAllCerts = new TrustManager[] {
            new X509TrustManager() {

                @Override
                public X509Certificate[] getAcceptedIssuers() {
                    return null;
                }

                @Override
                public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
                    // leave blank to trust all clients
                }

                @Override
                public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
                    // leave blank to trust all servers
                    for (X509Certificate c : chain) {
                        System.out.println(c.toString());
                    }
                }

            }
        };
        return trustAllCerts;
    }

}

但是,我得到以下错误:

javax.net.ssl.SSLException: hostname in certificate didn't match: <xyz.ch> != <localhost>

    at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:641)
    at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:576)

我确定我的证书代码已执行,那么可能是什么问题？

Answer 1

ALLOW_ALL不是正确的答案.您应该使用带有ext扩展名的keytool来设置具有正确名称的证书:

keytool -genkeypair \
   -keystore keystore.jks \
  -dname "CN=OLEKSIYS-W3T, OU=Sun Java System Application Server, O=Sun Microsystems, L=Santa Clara, ST=California, C=US" \
  -keypass changeit \
  -storepass changeit \
  -keyalg RSA \
  -keysize 2048 \
  -alias default \
  -ext SAN=DNS:localhost,IP:127.0.0.1 \
  -validity 9999

Answer 2

你可以用 SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER

SSLSocketFactory sf = new SSLSocketFactory(
    SSLContext.getInstance("TLS"),
    SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
Scheme sch = new Scheme("https", 443, sf);
httpclient.getConnectionManager().getSchemeRegistry().register(sch);

HttpGet httpget = new HttpGet("https://host/");
