Java1.7 access Https occur SSLProtocolException and CertificateException through SSL, and download java1.7

Java1.7 access Https occur SSLProtocolException and CertificateException through SSL, and download java1.7

I recently called one of the Advanced Mass Sending interfaces on the public platform:

Https://file.api.weixin.qq.com/cgi-bin/media/uploadvideo? When access_token = ACCESS_TOKEN, an exception is thrown during https access:

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

Keyword: unrecognized unacknowledged name.

Google, solution, code added:

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

Call this interface again to throw a new exception:

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

Continue to process. Add the following code:

 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());

The CustomizedHostnameVerifier class is as follows:

import javax.net.ssl.HostnameVerifier;import javax.net.ssl.SSLSession;/** * HostnameVerifier * bug fixed : 

Cause:


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.

In short:
Because this interface is not authenticated, https is not secure, and all the code needs to be dont verify.

When you configure the android SDK in eclipse 37, Fetching https: // dl-sslgooglecom/and appears.
This problem seems to be caused by a wall.
Now you can download the sdk-r18 sdk, can be downloaded normally, if you still can not download, you can contact me, I will send you a copy
