Node.JS：处理postdata读错误的正确方法是什么？

Question

If the ServerRequest object emits an error event, that means that the postdata could not be fully received, most likely due to a network failure. This type of network failure is most likely terminal in both directions, right? So, how should I right my code?

I could say res.writeHead(400); res.end() res.writeHead(400); res.end()

But is there a smarter way? Perhaps one that just 'does nothing', but will not result in a memory leak / hang. It seems like request.connection.destroy() is a good idea, but I am not sure if that is safe.

What would you recommend?

Answer 1

you don't need to do anything. internally, the socket/req/res will be destroyed. it'll be garbage collected eventually.

you don't need to send a response code - the connection is already destroyed so it's not going anywhere.
