Httpsurlconnection.setdefaulthostnameverifier (New Hostnameverifier () {public      Boolean verify (String hostname, SSLsession SSLs) {              return true;          }  });  

SSLs is the SSL certificate that is received from the server (specifically to be verified)

Hostname is the domain name of the URL visited

When HTTPS default validation does not pass, you can override this method yourself, and if you return true, this means that the certificate is forced to trust, which is the usual weak trust. If you need to do the operation, you can get the server back from the SSLs the certificate data, with the domain name of their own request, certificate of the domain name of the visa, the certificate received the URL of the domain name to do a comparison, matching rules need to confirm their own. This domain name may also be IP, depending on the situation
