我在Debian系統上使用apache2 + mod_wsgi設置了django服務器（1.4，python 2.7）。從django的角度來看，一切都很完美，如果我運行manage.py runserver，開發服務器會正確顯示網站，但是，當我嘗試設置我的apache服務器來運行WSGI時，它無法顯示ValueError。Apache-Django WSGI異常：ValueError：格式爲零的長度字段名稱
這是mysite.wsgi
ALLDIRS = ['/usr/local/lib/python2.7/site-packages']
# the above directory depends on the location of your python installation.
# if using virtualenv, it will need to match your projects locale.
import os
import sys
import site
os.environ['DJANGO_SETTINGS_MODULE'] = 'ggDatabase.settings'
prev_sys_path = list(sys.path)
sys.path.append("/usr/local/lib/python2.7")
path = "/home/acad/statsdb/src"
if path not in sys.path:
sys.path.append(path)
sys.path.append("/home/acad/statsdb/src/ggDatabase")
for directory in ALLDIRS:
site.addsitedir(directory)
new_sys_path = []
for item in list(sys.path):
if item not in prev_sys_path:
new_sys_path.append(item)
sys.path.remove(item)
sys.path[:0] = new_sys_path
# change this depending on your project.
site.addsitedir("/home/acad/statsdb/src/ggDatabase/")
os.environ['PYTHON_EGG_CACHE'] = '/home/acad/.python-eggs'
os.environ['SETTINGS_MODULE'] = 'settings'
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()
這是Apache的虛擬主機配置：
<VirtualHost 127.0.0.1:8000>
ServerName mysite.com
ServerAlias www.mysite.com
<Directory /home/acad/statsdb/src/ggDatabase>
Order deny,allow
Allow from all
</Directory>
LogLevel warn
CustomLog /var/log/apache2/mysite.com.access.log combined
ErrorLog /var/log/apache2/mysite.com.error.log
WSGIDaemonProcess mysite.com user=acad group=acad threads=25 python-path=/usr/local/lib/python2.7
WSGIProcessGroup mysite.com
WSGIScriptAlias//home/acad/statsdb/src/ggDatabase/apache/mysite.wsgi
</VirtualHost>
這是確切的配置，我有我的測試服務器上，並可以正常訪問，但嘗試運行wsgi腳本時新服務器遇到問題：

錯誤是非常通用的，我真的不知道會出現什麼問題。有任何想法嗎？
在此先感謝！
