Key here is to force TLS 1.2 protocol, based on thislink here.
这里的关键是根据这里的链接强制使用 TLS 1.2 协议。
Only thing that I needed to correct here is to force TLS 1.2 protocol directly, like this:
我唯一需要在这里更正的是直接强制使用 TLS 1.2 协议，如下所示：
private class NoSSLv3SSLSocket extends DelegateSSLSocket {
private NoSSLv3SSLSocket(SSLSocket delegate) {
super(delegate);
}
@Override
public void setEnabledProtocols(String[] protocols) {
super.setEnabledProtocols(new String[]{"TLSv1.2"}); // force to use only TLSv1.2 here
}
}
