出于某种原因，有时当我的用户上传图片时，我会一直收到500错误，我无法自行复制。我在django / apache / wsgi日志中唯一能看到的是：
[core：error] [pid 17191]标题前的脚本输出结束：wsgi.py
我不知道从哪里开始...

我将LogLevel更改为Debug，我得到以下内容：

"""
This module contains the WSGI application used by Django's development server
and any production WSGI deployments. It should expose a module-level variable
named ``application``. Django's ``runserver`` and ``runfcgi`` commands discover
this application via the ``WSGI_APPLICATION`` setting.
Usually you will have the standard Django WSGI application here, but it also
might make sense to replace the whole Django WSGI application with a custom one
that later delegates to the Django one. For example, you could introduce WSGI
middleware here, or combine a Django application with an application of another
framework.
