Django UnicodeEncodeError，Apache2與Debian lenny上的mod_wsgi

Question

我在生產服務器上的unicode文件名有問題。當我試圖保存UnicodeEncodeError異常發生的文件時。 Devserver工作正常。

爲WWW的數據的所有區域設置爲 '的en_US.UTF-8'。

而且，我寫下的/ etc/apache2的/ envvars中

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

它並沒有幫助。

locale.getdefaultlocale（）返航（無，無），然後，添加以下行django.wsgi

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

後，它locale.getdefaultlocale（）開始返回（ 'EN_US'，「UTF8 「）

我注意到，sys.getdefaultencoding（）返回‘ASCII’，但我不知道如何解決它。

Answer 1

也增加django.wsgi：

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

簡單sys.setdefaultencoding函數（ 'UTF-8'）不會幫助，重載是重要 這是蟒蛇2 .X問題，而不是Django的

Answer 2

Debian不會相信用 '的/ etc/apache2的/ envvars中'。從Python腳本內部設置這些值將不起作用，因爲它不會初始化僅在進程啓動時發生的一些事情。

如果未查閱envvars，或者使用mod_wsgi 3.4並使用守護進程模式，將'lang'和'locale'選項設置爲WSGIDaemonProcess指令，則需要在Apache的init.d啓動腳本中設置變量。
