'unknownProtocol' 事件
当连接的客户端无法协商允许的协议(即 HTTP/2 或 HTTP/1.1)时,则会触发 'unknownProtocol'
事件。
事件句柄接收套接字进行处理。
如果没有为该事件注册监听器,则连接将终止。
可以使用传给 http2.createSecureServer()
的 'unknownProtocolTimeout'
选项指定超时。
请参阅兼容性 API。
The 'unknownProtocol'
event is emitted when a connecting client fails to
negotiate an allowed protocol (i.e. HTTP/2 or HTTP/1.1). The event handler
receives the socket for handling. If no listener is registered for this event,
the connection is terminated. A timeout may be specified using the
'unknownProtocolTimeout'
option passed to http2.createSecureServer()
.
