httpclient 无信任证书使用https

1、当不需要使用任何证书访问https网页时，只需配置信任任何证书

HttpClient http = new HttpClient();
String url = "https://payment.cib.com.cn/payment/api/rest";
Protocol myhttps = new Protocol("https", new MySSLProtocolSocketFactory(), 443);
Protocol.registerProtocol("https", myhttps);
PostMethod post = new PostMethod(url);

2、其中信任任何证书的类

import java.io.IOException;
import java.net.InetAddress;
import java.net.InetSocketAddress;
import java.net.Socket;
import java.net.SocketAddress;
import java.net.UnknownHostException;
import java.security.KeyManagementException;
import java.security.NoSuchAlgorithmException;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;

import javax.net.SocketFactory;
import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;

import org.apache.commons.httpclient.ConnectTimeoutException;
import org.apache.commons.httpclient.params.HttpConnectionParams;
import org.apache.commons.httpclient.protocol.ProtocolSocketFactory;
