Django 内部服务器错误而不是 404答案

【问题标题】：Django Internal Server Error instead of 404Django 内部服务器错误而不是 404
【发布时间】：2014-08-02 16:29:03
【问题描述】：

我正在使用 Django 1.6、uwsgi 和 nginx，应用程序运行正常，但我收到 500 错误，并且我尝试访问的每个无效 URL 都收到下面的电子邮件，而不是 404 错误。

我为http://my_project_url.com/whatever 甚至http://my_project_url.com/favicon.ico 得到这个

我查看了 URL，但没有匹配此模式的正则表达式。

这是来自电子邮件的回溯：

Traceback (most recent call last):

  File "/project/virtenv/local/lib/python2.7/site-packages/django/core/handlers/base.py", line 152, in get_response
    response = callback(request, **param_dict)

  File "/project/virtenv/local/lib/python2.7/site-packages/django/utils/decorators.py", line 99, in _wrapped_view
    response = view_func(request, *args, **kwargs)

  File "/project/virtenv/local/lib/python2.7/site-packages/django/views/defaults.py", line 30, in page_not_found
    body = template.render(RequestContext(request, {'request_path': request.path}))

  File "/project/virtenv/local/lib/python2.7/site-packages/debug_toolbar/panels/templates/panel.py", line 55, in _request_context__init__
    context = processor(request)

  File "./project/context_processors.py", line 88, in app_delegate
    app_name = resolve(request.path).app_name

  File "/project/virtenv/local/lib/python2.7/site-packages/django/core/urlresolvers.py", line 453, in resolve
    return get_resolver(urlconf).resolve(path)

  File "/project/virtenv/local/lib/python2.7/site-packages/django/core/urlresolvers.py", line 333, in resolve
    raise Resolver404({'tried': tried, 'path': new_path})

Resolver404: {u'path': u'favicon.ico', u'tried': [[<RegexURLResolver <module 'custom_

如果我尝试从我做raise Http404 的应用程序访问 URL，那很好，我会看到常规的 nginx 错误页面。

【解决方案1】：

似乎您有一个自定义处理器试图解析路径：

File "./project/context_processors.py", line 88, in app_delegate
  app_name = resolve(request.path).app_name

引用 django resolve() docs：

如果 URL 未解析，该函数会引发 Resolver404 异常（Http404 的子类）。

我建议你管理自定义处理器中的异常代码看起来像这样：

try:
    resolve_result = resolve(request.path)
    app_name = resolve_result.app_name
    ... your code ....
except Resolver404:
    pass
