'OCSPResponse' 事件

如果在创建 tls.TLSSocket 并收到 OCSP 响应时设置了 requestOCSP 选项，则会触发 'OCSPResponse' 事件。 监听器回调在调用时传入一个参数：

• response <Buffer> 服务器的 OCSP 响应

通常，response 是来自服务器 CA 的数字签名对象，其中包含有关服务器证书吊销状态的信息。

The 'OCSPResponse' event is emitted if the requestOCSP option was set when the tls.TLSSocket was created and an OCSP response has been received. The listener callback is passed a single argument when called:

• response <Buffer> The server's OCSP response

Typically, the response is a digitally signed object from the server's CA that contains information about server's certificate revocation status.
