Java1.7 SSL訪問Https occur SSLProtocolException and CertificateException，java1.7下載

最近在調用公眾平台進階群發介面之一：

https://file.api.weixin.qq.com/cgi-bin/media/uploadvideo?access_token=ACCESS_TOKEN 時，https訪問拋出異常：

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

異常中出現關鍵字：unrecognized 未被承認的name。

google之，處理辦法，代碼加入：

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

再次調用該介面，拋出新的異常：

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

繼續處理，代碼加入：

 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());

其中CustomizedHostnameVerifier類如下：

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 * @since */public class CustomizedHostnameVerifier implements HostnameVerifier{    @Override    public boolean verify(String arg0, SSLSession arg1)    {        return true;    }}

原因：

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.

簡而言之：

因為的這個介面是未認證https不安全的，所有需要代碼中需要dont verify。
