httpclient4.2 https post接口linux使用TLSv1.2协议

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

import java.io.InputStream;

import java.net.URI;
import java.net.URLEncoder;
import java.util.ArrayList;
import java.util.List;
import java.util.Map;

import javax.net.ssl.X509TrustManager;

import org.apache.http.HttpResponse;
import org.apache.http.NameValuePair;
import org.apache.http.client.HttpClient;
import org.apache.http.client.entity.UrlEncodedFormEntity;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.client.utils.URIUtils;
import org.apache.http.client.utils.URLEncodedUtils;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.message.BasicNameValuePair;
import org.apache.http.params.CoreConnectionPNames;
import org.apache.http.params.CoreProtocolPNames;
import org.apache.http.protocol.HTTP;
import org.apache.http.util.EntityUtils;

public class HttpSSLClientUtil {

/** 发送POST   支持http、https
     * @param url        post地址
