Django UnicodeEncodeError, Apache2 with mod_wsgi on Debian l

我在生产服务器上使用Unicode文件名时遇到问题。当我尝试保存文件时，UnicodeEncode错误发生异常。开发服务器工作正常。

www-data 的所有区域设置都是"en_US。UTF-8'。

另外，我在/etc/apache2/envvars 中写下了

export LANG='en_US.UTF-8' 
export LC_ALL='en_US.UTF-8'

它没有帮助。

locale.getdefaultlocale（）返回（None，None），然后我在 django.wsgi 中添加以下行

os.environ['LANG']='en_US.UTF-8'
os.environ['LC_ALL']='en_US.UTF-8'

之后 locale.getdefaultlocale（）开始返回（'en_US'， 'UTF8'）

我注意到sys.getdefaultencoding（）返回'ascii'，但我不知道如何解决它。

Exception Type: UnicodeEncodeError at /admin/django_pencil/picture/add/
Exception Value: 'ascii' codec can't encode characters in position 58-65: ordinal not in range(128)

也添加到 django.wsgi：

import sys
reload(sys)
sys.setdefaultencoding('utf-8')

简单的 sys.setdefaultencoding（'utf-8'）将无济于事，重新加载很重要这是python 2.x的问题，而不是django

Debian 我不相信使用'/etc/apache2/envvars'。从 Python 脚本内部设置这些值将不起作用，因为它不会初始化仅在进程启动时发生的某些操作。

如果没有咨询 envvar，则需要在 Apache 的 init.d 启动脚本中设置变量，或者使用 mod_wsgi 3.4 并使用守护程序模式，将"lang"和"locale"选项设置为 WSGIDaemonProcess 指令。
