outgoingMessage.writableEnded

• 类型：<boolean>

如果已调用 outgoingMessage.end()，则为 true。此属性并不表示数据是否已刷新。为此，请使用 message.writableFinished。

【Is true if outgoingMessage.end() has been called. This property does not indicate whether the data has been flushed. For that purpose, use message.writableFinished instead.】
