Question

我一直在使用mod_wsgi运行一个由mod_auth_sspi启用单点登录的Django应用程序。

Apache / 2.2.21（Win32）mod_wsgi / 3.3 Python / 2.7.2 mod_auth_sspi / 1.0.4

问题是，我无法添加第二个使用相同模块的Django应用程序，因为我也想使用单点登录。如果我添加第二个应用程序，Apache只会验证第一个请求的应用程序。第二个抛出错误500 - 内部服务器错误。如果我重新启动Apache并尝试首先请求第二个应用程序，它可以工作。但是当我请求第一个应用程序时，它会抛出错误500（与第一个相同的错误）。

error.log中：

您知道如何使这两个应用程序与单点登录一起使用吗？我不知道，如果是Django的错，mod_wsgi错误或mod_auth_sspi错误。你能帮帮我吗？

编辑：看起来，它不依赖于mod_auth_sspi模块。

Answer 1

这似乎是一个pywin32错误，在这里回答： Multiple django sites on Apache / Windows / mod_wsgi - problem with win32

有一些python版本检查，它对模块和引发做了一些事情：

AssertionError: assert sys.modules[modname] is old_mod

报告了Bug，但未解决：

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

临时解决方案在 win32 / lib / pywintypes.py 中注释掉两行：

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__)

使用mod_auth_sspi和mod_wsgi在Apache上运行两个Django应用程序
