每次使用 PyAudio 播放声音时，我都会收到错误消息，并且无法抑制它们。

我有一个问题,即"不存在"的网址能够显示.例如,我在/ myapp/login访问一个url,它可以工作.然后我去/ myapp/login/login,它仍然有效.然后我去/ myapp/insertrandomcharactershere/login,它仍然有效.这将适用于我的子路径/ myapp/so/myapp/register,/ myapp/login和/ myapp/myaccount中的每个URL.似乎只要它以我的urlconf中的名称结尾就可以了.我一直无法解决这个问题所以我从我的登录页面和我的urlconfs中添加了一些代码,这些代码应该包含问题.

我应该404任何不是/ myapp /,/ myapp/login /,/ myapp/register /,/ myapp/myaccount /
