使用org.apache.commons.httpclient时如何忽略ssl认证？

Question

当我使用Apache包commons-httpclient-3.1.jar时，我尝试使用以下逻辑来避免ssl认证。

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) {
                }
            }
        };

        // Install the all-trusting trust manager
        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);

但不幸的是，我仍然有错误：Https客户端证书身份验证错误：“javax.net.ssl.SSLHandshakeException：sun.security.validator.ValidatorException：PKIX路径构建失败：sun.security.provider.certpath.SunCertPathBuilderException”

然后我选择了httpclient-4.3.3.jar，上面的逻辑也没有用，但是如果添加下面的逻辑，它就可以了。

  httpClient.getConnectionManager().getSchemeRegistry().register(new Scheme("https", socketFactory, 443));

httpClient是DefaultHttpClient的实例，socketfactory初始化为：

   SSLContext ctx = SSLContext.getInstance("TLS");
   ctx.init(null, new TrustManager[] { xtm }, null);
   SSLSocketFactory socketFactory = new SSLSocketFactory(ctx);
   socketFactory.setHostnameVerifier(hostnameVerifier);             

似乎Scheme Register是必须的。

但对于包commons-httpclient-3.1.jar，如何做方案寄存器？

经过调查，以下方式可以满足要求。

Protocol easyhttps = new Protocol("https", (ProtocolSocketFactory)new EasySSLProtocolSocketFactory(), 443);
Protocol.registerProtocol("https", easyhttps);

EasySSLProtocolSocketFactory位于包commons-httpclient-contrib-3.1.jar中
