'tlsClientError' 事件

在建立安全连接之前发生错误时会触发 'tlsClientError' 事件。 监听器回调在调用时传入两个参数：

• exception <Error> 描述错误的 Error 对象
• tlsSocket <tls.TLSSocket> 错误源自的 tls.TLSSocket 实例。

The 'tlsClientError' event is emitted when an error occurs before a secure connection is established. The listener callback is passed two arguments when called:

• exception <Error> The Error object describing the error
• tlsSocket <tls.TLSSocket> The tls.TLSSocket instance from which the error originated.
