1. SSLClient 继承DefaultHttpClient ，设定TLSv1.2，https允许所有hostname

import java.security.cert.CertificateException;import java.security.cert.X509Certificate;import javax.net.ssl.SSLContext;import javax.net.ssl.TrustManager;import javax.net.ssl.X509TrustManager;import org.apache.http.conn.ClientConnectionManager;import org.apache.http.conn.scheme.Scheme;import org.apache.http.conn.scheme.SchemeRegistry;import org.apache.http.impl.client.DefaultHttpClient;  public class SSLClient extends DefaultHttpClient {          public SSLClient() throws Exception {              super();              SSLContext ctx = SSLContext.getInstance("TLSv1.2");              X509TrustManager tm = new X509TrustManager() {				@Override				public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {					// TODO Auto-generated method stub									}				@Override				public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {					// TODO Auto-generated method stub									}				@Override				public X509Certificate[] getAcceptedIssuers() {					// TODO Auto-generated method stub					return null;				}              };              ctx.init(null, new TrustManager[] { tm }, null);              org.apache.http.conn.ssl.SSLSocketFactory ssf = new org.apache.http.conn.ssl.SSLSocketFactory(ctx,                      org.apache.http.conn.ssl.SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);              ClientConnectionManager ccm = this.getConnectionManager();              SchemeRegistry sr = ccm.getSchemeRegistry();              sr.register(new Scheme("https", 443, ssf));          }      }

　2.　https使用SSLClient 创建client
