ConnectionAbortedError: [WinError 10053] 你的主机中的软件中止了一个已建立的

Posted 2023-05-17

参考技术A 原因：ajax默认是异步提交，可是有时候我们会发现,本来要求请求马上出现,可是异步会导致后面突然再执行,这样就出问题了。
ajax请求时加上

async : false,

Django ConnectionAbortedError + TypeError + AttributeError

【中文标题】Django ConnectionAbortedError + TypeError + AttributeError

【问题描述】：

我正在使用 Python 3.6.0 + django 1.11 + windows 7 64 位

我的网站运行良好，但我不断收到此错误。

ConnectionAbortedError: [WinError 10053] 已建立连接 被主机中的软件中止

TypeError: 'NoneType' 对象不可下标

AttributeError: 'NoneType' 对象没有属性 'split'

为什么我得到这个..？以及如何修复这些错误？

【问题讨论】：

它试图在 None 对象上“拆分”，在您的情况下是“self.status”所以，您的响应对象由于某种原因没有状态......是你不要设置它（不确定，它应该默认为 200）或者你将它设置为一些无效的值，它可能会被删除......你需要做更多的挖掘......

你应该在你的代码中使用异常处理...

你可能遇到过known Python Bug。

这是由客户端的 ajax 调用触发的吗？是什么触发了这个？

【参考方案1】：

这已在 Python 中得到修复：https://github.com/python/cpython/pull/9713

它将在下一版本的 Python 3.7 及更高版本中提供。
