Question

今天早上我的收件箱里有大约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.

但是当我转到我的生产服务器上的指定URL时，我会得到我的404页面，就像我期望的那样，并且没有发送电子邮件。那么为什么/这些机器人如何生成（我认为是什么）内部服务器错误？我该如何预防呢？

我的view_profile urlpattern定义如下：

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

的子模式

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

它的定义与我的其他任何URL模式完全相同，并且它需要传递给它的ID ....所以我不知道它是如何被没有参数击中的。

完整的痕迹：

重新命名路径以保护无辜者。

Answer 1

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

Answer 2

可能是机器人只是请求所有可映射的URL（作为网站爬虫），而不是尊重重定向请求或cookie。

Answer 3

你可能想要一个robots.txt文件来抵御僵尸程序。将其添加到主urls.py文件中。对于开发环境，应在settings.py中将DISALLOW_ROBOTS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")),
    )
