如何在生产服务器上禁用 NoReverseMatch 错误电子邮件？

Question

今天早上，我的收件箱中有大约 100 封电子邮件告诉我各种页面不存在（我怀疑某些机器人正在寻找安全漏洞）。错误是：

NoReverseMatch: Reverse for 'view_profile' with arguments '('',)' and keyword arguments '{}' not found.

但是，当我转到生产服务器上的指定 URL 时，我得到了 404 页面，正如我所期望的那样，并且没有发送任何电子邮件。那么这些机器人为什么/如何产生（我认为是）内部服务器错误？我该如何预防？

我的view_profile urlpattern 定义如下：

url(r'^(?P<id>\d+)$', name="view_profile")

这是一个子模式

RegexURLResolver(r'^contacts/', 'profiles.views.user_profile'),

它的定义与我的任何其他 URL 模式完全一样，并且需要将 ID 传递给它......所以我不知道它是如何在没有参数的情况下被击中的。

完整的跟踪：

重命名路径以保护无辜者。

Answer 1

在某个地方（可能在模板中），您使用空字符串而不是 id 解析 view_profile。所以找出它为什么会发生并修复它

Answer 2

可能是机器人只是简单地请求所有可映射的 url（就像网站爬虫一样），而不尊重重定向请求或 cookie。

Answer 3

您可能需要一个 robots.txt 文件来抵御机器人。将此添加到您的主 urls.py 文件中。 DISALLOW_ROBOTS 应在开发环境的 settings.py 中设置为 True。

if settings.DISALLOW_ROBOTS:
    urlpatterns += patterns('',
        (r'^robots\.txt$', lambda r: HttpResponse("User-agent: *\nDisallow: /", mimetype="text/plain")),
    )
else:
    urlpatterns += patterns('',
        (r'^robots\.txt$', lambda r: HttpResponse("User-agent: *\nDisallow: ", mimetype="text/plain")),
    )
