客户端断开连接 [英] The client disconnected

问题描述

我在WebAPI日志中遇到以下错误

I'm getting the following error in logs for WebAPI

如何通过异常过滤器处理和忽略这些异常?为什么会发生此错误，我该如何重现该错误?我只想捕获并忽略客户端已断开连接，但不是全部 HttpException

How can I handle and ignore these exceptions by exception filter? Why this error occurs and how can I reproduce that? I wanna catch and ignore only The client disconnected but not all HttpException

我看到了这个类似的问题但是如何在异常过滤器中做到这一点?

I saw this similar question but how can I do that in exception filter?

推荐答案

您可以忽略这些异常.

该异常说明了问题所在:客户端已断开连接".这意味着客户端启动了一个请求，但随后断开了连接，然后才开始读取所有响应.

The exception says what the problem is: "The client disconnected". It means that the client initiated a request but then disconnected before it bothered to read all of the response.

有多种原因可能会导致这种情况，但是(除非您的服务器端互联网连接不稳定)，这几乎肯定是客户端的问题.我经常自己看到这些东西，而且大多数情况下似乎与机器人有关.所以我将它们过滤掉并忽略它们.

There are any numbers of reasons why that might be the case, but (unless you have a dodgy internet connection at your server end) it is almost certainly an issue at the client end. I regularly see these myself and mostly it seems to be related to a bot. So I filter them out and ignore them.
