使用mod_auth_sspi和mod_wsgi在Apache上運行兩個Django應用程序

Question

我一直在使用mod_wsgi運行一個使用mod_auth_sspi啓用單點登錄的Django應用程序。

阿帕奇/ 2.2.21（Win32的）的mod_wsgi/3.3的Python/2.7.2 mod_auth_sspi/1.0.4

問題是，我無法添加第二Django應用程序，其使用相同的模塊，因爲我也想使用單點登錄。如果我添加第二個應用程序，Apache只驗證第一個請求的應用程序。第二個拋出錯誤500 - 內部服務器錯誤。如果我重新啓動Apache並嘗試首先請求第二個應用程序，它將起作用。但是當我請求第一個應用時，它會拋出錯誤500（與第一個錯誤相同）。

error.log中：

application = django.core.handlers.wsgi.WSGIHandler() 

你知道怎麼做才能讓這兩個應用程序都能使用單一登錄？我不知道，如果它是Django的錯，mod_wsgi錯或者mod_auth_sspi錯。你能幫我嗎？

編輯： 它看起來，它不依賴於mod_auth_sspi模塊。

Answer 1

這似乎是一個pywin32錯誤，回答在這裏： Multiple django sites on Apache/Windows/mod_wsgi - problem with win32

有一些Python版本檢查，其中做一些事模塊，並提出：

AssertionError: assert sys.modules[modname] is old_mod 

的Bug報告，但沒有得到解決：

https://sourceforge.net/tracker/?func=detail&aid=2905909&group_id=78018&atid=551954

https://sourceforge.net/tracker/?func=detail&aid=3496224&group_id=78018&atid=551954

臨時解決方法是註釋掉的win32/lib中兩行/ pywintypes.py：

if sys.version_info < (3,0): 
    #next two lines are problematic!!!!! 
    #assert sys.modules[modname] is old_mod 
    #assert mod is old_mod 
    pass 
else: 
    assert sys.modules[modname] is not old_mod 
    assert sys.modules[modname] is mod 
    # as above - re-reset to the *old* module object then update globs. 
    sys.modules[modname] = old_mod 
    globs.update(mod.__dict__)
