Java1.7 SSL访问Https occur SSLProtocolException and CertificateException

最近在调用微信公众平台高级群发接口之一：

https://file.api.weixin.qq.com/cgi-bin/media/uploadvideo?access_token=ACCESS_TOKEN 时，https访问抛出异常：

javax.net.ssl.SSLProtocolException: handshake alert: unrecognized_name

google之，处理办法，代码加入：

 //bug fiexd for: javax.net.ssl.SSLProtocolException: handshake alert: unrecognized_name
 System.setProperty ("jsse.enableSNIExtension", "false");

再次调用该接口，抛出新的异常：

javax.net.ssl.SSLHandshakeException: java.security.cert.CertificateException: No subject alternative DNS name matching file.api.weixin.qq.com found.

继续处理，代码加入：

 URL url = new URL(requestUrl);
 httpUrlConn = (HttpsURLConnection)url.openConnection();
 httpUrlConn.setSSLSocketFactory(ssf);

 //bug fixed for: java.security.cert.CertificateException: No subject alternative DNS name matching
 httpUrlConn.setHostnameVerifier(new CustomizedHostnameVerifier());

import javax.net.ssl.HostnameVerifier;
import javax.net.ssl.SSLSession;


/**
 * HostnameVerifier
 * bug fixed : <http://iteches.com/archives/45015>
 * @author will_awoke
 * @version 2014-8-15
 * @see CustomizedHostnameVerifier

 */
public class CustomizedHostnameVerifier implements HostnameVerifier
{

    @Override
    public boolean verify(String arg0, SSLSession arg1)
    {
        return true;
    }

}

and then apply this class to your single SSL connection
HttpsURLConnection connection = (HttpsURLConnection) new URL("
https://url").openConnection();
connection.setHostnameVerifier(new CustomizedHostNameVerifier());
or apply to all SLL connection
HttpsURLConnection.setDefaultHostnameVerifier(new CustomizedHostnameVerifier());
However this method might pose a security risk because basically we don’t verify the hostname anymore. The server may use other website’s certificate and the program will still accept it.

简而言之：

因为微信的这个接口是未认证https不安全的，所有需要代码中需要dont verify。
