'wantTrailers' 事件


'wantTrailers' 事件在 Http2Stream 已将要在帧上发送的最后 DATA 帧排队并且 Http2Stream 准备好发送尾随标头时触发。 在发起请求或响应时,必须设置 waitForTrailers 选项才能触发此事件。

The 'wantTrailers' event is emitted when the Http2Stream has queued the final DATA frame to be sent on a frame and the Http2Stream is ready to send trailing headers. When initiating a request or response, the waitForTrailers option must be set for this event to be emitted.
