推荐答案

在URLconf中，您需要使用正则表达式中的捕获组来实现视图中的位置或关键字参数。如果使用命名捕获组，则使用关键字参数;

In a URLconf, you need to use capturing groups in your regex to achieve positional or keyword arguments in your view. If you use a named capture group, then keyword arguments are used; otherwise, positional arguments are used.

这是你的 url（）行应该如下所示：

Here is what your url() line should look like:

url(r'^confirmemail/([a-zA-Z0-9]{10})/$', 'blog.views.confirmemail'),
# or
url(r'^confirmemail/(?P<token>[a-zA-Z0-9]{10})/$', 'blog.views.confirmemail'),

第一种形式使用位置参数（位置参数由捕获组排序在URL中）。第二种形式使用关键字参数，在这种情况下令牌。第二种形式是更多的字符，但对参数重新排序也是安全的。

The first form uses a positional argument (and positional arguments are ordered by the capture groups in the URL). The second form uses a keyword argument, in this case token. The second form is more characters but will also be safe against parameter reordering.
