例外:javax.net.ssl.SSLPeerUnverifiedException:peer未经过身份验证

Question

public HttpClientVM() {

    BasicHttpParams params = new BasicHttpParams();
    ConnManagerParams.setMaxTotalConnections(params, 10);
    HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
    HttpProtocolParams.setUseExpectContinue(params, false);
    HttpConnectionParams.setStaleCheckingEnabled(params, true);
    HttpConnectionParams.setConnectionTimeout(params, 30000);
    HostnameVerifier hostnameVerifier=
          org.apache.http.conn.ssl.SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER;
    HttpsURLConnection.setDefaultHostnameVerifier(hostnameVerifier);
    SSLSocketFactory socketFactory = SSLSocketFactory.getSocketFactory();
    socketFactory.setHostnameVerifier((X509HostnameVerifier) hostnameVerifier);
    SchemeRegistry schemeRegistry = new SchemeRegistry();
    schemeRegistry.register(new Scheme("http",socketFactory, 80));
    schemeRegistry.register(new Scheme("https",socketFactory, 443));
        ThreadSafeClientConnManager manager = new ThreadSafeClientConnManager(params, schemeRegistry);
        // Set verifier     
        client = new DefaultHttpClient(manager, params);    
    }

问题:

执行时client.accessURL(url),会发生以下错误:

Answer 1

过期的证书是我们的"javax.net.ssl.SSLPeerUnverifiedException:peer not authenticated"的原因.

keytool -list -v -keystore filetruststore.ts

    Enter keystore password:
    Keystore type: JKS
    Keystore provider: SUN
    Your keystore contains 1 entry
    Alias name: somealias
    Creation date: Jul 26, 2012
    Entry type: PrivateKeyEntry
    Certificate chain length: 1
    Certificate[1]:
    Owner: CN=Unknown, OU=SomeOU, O="Some Company, Inc.", L=SomeCity, ST=GA, C=US
    Issuer: CN=Unknown, OU=SomeOU, O=Some Company, Inc.", L=SomeCity, ST=GA, C=US

Answer 2

如果您的服务器基于JDK 7并且您的客户端位于JDK 6上并使用SSL证书,则会出现此异常.在JDK 7中,sslv2hello消息握手默认禁用,而在JDK 6中,sslv2hello消息握手已启用.因此,当您的客户端尝试连接服务器时,将向服务器发送sslv2hello消息,并且由于sslv2hello消息禁用,您将收到此异常.要解决此问题,您必须将客户端移至JDK 7,或者必须使用6u91版本的JDK.但要获得此版本的JDK,您必须获得MOS(My Oracle Support)Enterprise支持.这个补丁不公开.

Answer 3

此错误是因为您的服务器没有有效的SSL证书.因此,我们需要告诉客户端使用不同的TrustManager.这是一个示例代码:

SSLContext ctx = SSLContext.getInstance("TLS");
X509TrustManager tm = new X509TrustManager() {

    public void checkClientTrusted(X509Certificate[] xcs, String string) throws CertificateException {
    }

    public void checkServerTrusted(X509Certificate[] xcs, String string) throws CertificateException {
    }

    public X509Certificate[] getAcceptedIssuers() {
        return null;
    }
};
ctx.init(null, new TrustManager[]{tm}, null);
SSLSocketFactory ssf = new SSLSocketFactory(ctx,SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
ClientConnectionManager ccm = base.getConnectionManager();
SchemeRegistry sr = ccm.getSchemeRegistry();
sr.register(new Scheme("https", 443, ssf));

client = new DefaultHttpClient(ccm, base.getParams());

Answer 4

如果客户端指定"https"但服务器仅运行"http",则可以获取此信息.因此,服务器不期望建立安全连接.
