从 POST reuqest 到 django vai WSGI 和 apache 的 HTTP 500 错误

  • 772

我在 ubuntu 9.10 上安装了一个带有 mod_wsgi 和 apache2 的 Django Web 应用程序

我使用以下代码通过 HTTP 帖子对我网站的另一部分进行用户身份验证。它只需要一个 HTTP 200。

from django.contrib.auth import authenticate
from django.http import HttpResponse


def post_authentication_api(request):
    if request.method == 'POST':
        print request
        user = authenticate(username=request.POST['user'], password=request.POST['pass'])
        if user is not None:
            if user.is_active:
                print "correct"
                return HttpResponse("correct", mimetype="text/plain")
            else:
                print "disabled"
                return HttpResponse("disabled", mimetype="text/plain", status=401)
        else:
            print "incorrect"
            return HttpResponse("incorrect", mimetype="text/plain", status=401)

当我使用 python manage.py runserver 命令运行它并且其他应用程序验证正常时，这一切正常。但是，当我将它加载到 apache 中时，我得到一个 500 内部错误。实际上，当我运行以下 python 代码时

import urllib
import urllib2

url = 'http://192.168.0.5/radiobusi/auth/post_authentication_api'
values = {'user' : 'Michael Foord',
          'pass' : 'Northampton',}

data = urllib.urlencode(values)
req = urllib2.Request(url, data)
response = urllib2.urlopen(req)
the_page = response.read()

我明白了

Traceback (most recent call last):
  File "testURL.py", line 10, in <module>
    response = urllib2.urlopen(req)
  File "/usr/lib/python2.6/urllib2.py", line 124, in urlopen
    return _opener.open(url, data, timeout)
  File "/usr/lib/python2.6/urllib2.py", line 395, in open
    response = meth(req, response)
  File "/usr/lib/python2.6/urllib2.py", line 508, in http_response
    'http', request, response, code, msg, hdrs)
  File "/usr/lib/python2.6/urllib2.py", line 433, in error
    return self._call_chain(*args)
  File "/usr/lib/python2.6/urllib2.py", line 367, in _call_chain
    result = func(*args)
  File "/usr/lib/python2.6/urllib2.py", line 516, in http_error_default
    raise HTTPError(req.get_full_url(), code, msg, hdrs, fp)
urllib2.HTTPError: HTTP Error 500: INTERNAL SERVER ERROR

这是我的虚拟主机文件

这是我的 wsgi 文件

import os
import sys

apache_configuration= os.path.dirname(__file__)
project = os.path.dirname(apache_configuration)
workspace = os.path.dirname(project)
sys.path.append(workspace) 

sys.path.append('/usr/local/lib/python2.6/dist-packages/Django-1.1.1-py2.6.egg/django/')
sys.path.append('/home/munderwo/public_html/radiobusi.com/RadioBusiSite/mysite/')

os.environ['PYTHON_EGG_CACHE'] = '/home/munderwo/public_html/radiobusi.com/egg_cache'
os.environ['DJANGO_SETTINGS_MODULE'] = 'mysite.settings'
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

我已经在 ~/public_html/radiobusi.com/ 上将所有权限设置为 777，并将 loggin 转为在 apache 和虚拟主机上进行调试。任何人有任何其他想法这可能是什么？

干杯

为了得到这些，我停止了 apache。删除了日志。再次触动了他们。然后重新启动 apache 并尝试了两次 POST 请求。

这是来自 /var/log/apache2/error.log 的主 apache 日志文件。我已经包含了它关闭自己的消息作为时间跟踪它的一种方式。

同样在我的 testURL.py 中，我相信我正在打印出响应。好吧，至少我正在尝试。用线条

response = urllib2.urlopen(req)
the_page = response.read()

有一个更好的方法吗？

更新：根据评论中的要求添加了 urls.py

from django.conf.urls.defaults import *
from django.contrib import admin
from django.contrib.auth import forms

admin.autodiscover()

urlpatterns = patterns('',
    (r'^admin/(.*)', admin.site.root),
    (r'^polls/', include('mysite.polls.urls')),
    (r'auth/post_authentication_api$', 'mysite.users.views.post_authentication_api'),
    (r'^site_media/(?P<path>.*)$', 'django.views.static.serve', {'document_root': '/Users/munderwood/Documents/Aptana Studio Workspace/RadioBusiSite/mysite/media/'}),    
)

据我所知，我的 apache2.conf 没有 ErrorDocument 设置。它被注释掉了。

好的 设法从中得到一个 django 错误页面。相当奇怪。

Environment:

Request Method: POST
Request URL: http://bertha.homeunix.org:3000/radiobusi/auth/post_authentication_api

Python Version: 2.6.4
Installed Applications:

 'django.contrib.sites',
 'django.contrib.admin',
 'django.contrib.flatpages',
 'mysite.polls',
 'mysite.RadioBusi',
 'mysite.Support',
 'mysite.users']
Installed Middleware:
('django.middleware.common.CommonMiddleware',
 'django.contrib.sessions.middleware.SessionMiddleware',
 'django.contrib.auth.middleware.AuthenticationMiddleware',
 'django.contrib.flatpages.middleware.FlatpageFallbackMiddleware')


Traceback:
File "/usr/local/lib/python2.6/dist-packages/Django-1.1.1-py2.6.egg/django/core/handlers/base.py" in get_response
  92.                 response = callback(request, *callback_args, **callback_kwargs)

Exception Type: TypeError at /auth/post_authentication_api
Exception Value: post_authentication_api() takes exactly 2 arguments (1 given)

POST
Variable    Value
user    u'e_username'
pass        u'e_password'

POST 下的东西是 post 变量。希望这可以帮助。这显然与我的设置有关。奇怪的是，当我在 django 测试服务器中运行相同的代码时它可以工作，而一旦我把它放在 apache 网络服务器上它就会这样做？

再次感谢你的帮助！

    好的，所以我们再次归结为用户错误。在某些时候问题发生了变化，因为我更改了上面的一些代码，所以

    def post_authentication_api(request):

    变成了

    def post_authentication_api(self, request):

    这不起作用，因为正如格雷厄姆在 django 邮件列表中所说

    “如果你......有一个不是类方法的函数的'self'第一个参数，很明显你会得到：”

    Exception Type: TypeError at /auth/post_authentication_api 
  Exception Value: post_authentication_api() takes exactly 2 arguments 
(1 given)

    因此，在我解决了这个问题之后（据我所知），我找到了问题的根源，那就是 wsgi 阻塞了 sys.stdout。我认为这对我来说似乎很公平，我的代码中有一些打印语句，这就是它没有运行的原因。一个非常简单的问题，由于某种原因变得非常复杂。

    无论如何，非常感谢格雷厄姆上周在这方面帮助了我。他一直不知疲倦，对一个对最终结果感到尴尬的人非常包容。一些投票将向他提出意见，我也非常感谢。

    再次感谢
