python - Django 内部服务器错误而不是 404

Question

我使用的是 Django 1.6、uwsgi 和 nginx，该应用程序运行良好，但我收到 500 错误和下面针对我尝试访问的每个无效 URL 的电子邮件，而不是 404 错误。

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

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追溯:

Traceback (most recent call last):

    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_

如果我尝试从应用程序访问一个 URL，我在其中执行 raise Http404 没问题，我会收到常规的 nginx 错误页面。

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()文档:

If the URL does not resolve, the function raises a Resolver404 exception (a subclass of Http404) .

我建议您在自定义处理器中管理异常代码如下:

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