简介: 7. 2023-11-20 12:29:32,542 [tornado.general :456 ][WARNING ][3052] Got events for closed stream Non

这个警告表明 Tornado 检测到了有事件(events)被发送到一个已经关闭的流(stream)。在 Tornado 中,一个流代表一个请求或响应的数据流。这个警告可能意味着在请求处理的过程中,尝试向已经关闭的流发送了事件。

可能的原因和解决方法:

异步操作处理不当: 在 Tornado 中,当你处理异步请求时,需要确保异步操作正确地处理。如果某个异步操作在请求处理完毕后仍在进行,并且试图向已关闭的流发送事件,就会触发这个警告。

解决方法: 确保在请求处理的异步操作中不再试图发送事件到已关闭的流。可以通过检查请求的 request.connection.stream.closed() 方法来验证流是否已关闭。

处理请求时关闭了连接: 在处理请求的过程中,有可能手动关闭了连接,但仍然有异步操作在尝试发送事件。

解决方法: 检查请求处理过程中是否存在手动关闭连接的代码,并确保不再尝试向已关闭的连接发送事件。

并发请求问题: 在高并发的环境中,可能会发生竞态条件,导致在某些情况下关闭了连接,但在异步操作中仍然尝试向已关闭的流发送事件。

解决方法: 确保对于每个请求,异步操作都以正确的方式处理,并且不会在连接已关闭后仍然执行。

这个警告的具体原因需要根据你的代码和上下文来进一步分析。你可能需要检查与请求处理相关的异步代码,确保在流已关闭的情况下不再执行任何发送事件的操作。
