Question

我在bottle之上构建了一个非常简单的API服务器。只是在被调用时返回JSON，JSON的内容是随机字符串。它很棒。

此服务器昨天被漏洞扫描程序（nessus）扫描并因扫描程序的错误行为而崩溃。我在下面添加了Traceback信息，其中显示了error: [Errno 10054] An existing connection was forcibly closed by the remote host例外。

我的问题如下：谁应该处理这个问题？

这是nessus，它是不是在做什么？一方面是的，它应该以标准方式运行（这是一种扫描仪，其中包括用于工业扫描的扫描仪，它可以满足各种设备并且应该尝试降低崩溃的风险）。另一方面，生活是残酷的，接收端（被扫描的东西）应该能够应付。
这是bottle吗？它是一个框架，应该处理典型的，不那么典型的Web流量，并给程序员留下处理业务逻辑而不是内部的任务
这是我吗？处理所有可能的例外

我问我希望帮助改进nessus或bottle（或我自己） - 这不是一个严格的编程问题（“如何捕捉异常”）所以如果你真的感觉如此，投票以意见为基础关闭，但我仍然要求我将其视为“程序员方法论”问题。

应该在何处（和由谁）捕获此例外情况？
