request.destroy([error])
error<Error>
对接收到 Http2ServerRequest 的 Http2Stream 调用 destroy()。如果提供了 error,将触发 'error' 事件,并将 error 作为参数传递给该事件的任何监听器。
【Calls destroy() on the Http2Stream that received
the Http2ServerRequest. If error is provided, an 'error' event
is emitted and error is passed as an argument to any listeners on the event.】
如果流已经被销毁,则什么也不做。
【It does nothing if the stream was already destroyed.】
