httpcomponents-client-4.3.4 HTTPS地址访问

基于httpcomponents-client-4.3.4进行https地址访问，在网上收集做法如下(未验证其正确性,仅供参考):

1.引用httpcomponents-client-4.3.4中的相关jar包，引用org.json.jar

我猜测MySSLSocketFactory可能的实现如下:

import javax.net.ssl.HostnameVerifier;

import org.apache.http.conn.scheme.SocketFactory;
import org.apache.http.conn.ssl.SSLSocketFactory;
import org.apache.http.conn.ssl.X509HostnameVerifier;

public class MySSLSocketFactory {
    private static SSLSocketFactory socketFactory = null;

    @SuppressWarnings("deprecation")
    public static SocketFactory getInstance() {
        if(null == socketFactory){
            HostnameVerifier hostnameVerifier = org.apache.http.conn.ssl.SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER;
            socketFactory = SSLSocketFactory.getSocketFactory();
            socketFactory.setHostnameVerifier((X509HostnameVerifier) hostnameVerifier);
        }
        return socketFactory;
    }

}
