decorator（）得到了意外的关键字参数'trim_url_limit'

Question

decorator（）得到了意外的关键字参数'trim_url_limit'

urlfiltertrunc在第183行出现错误

“ return mark_safe（django_165_urlize_impl（value，trim_url_limit = int（limit），nofollow = True，autoescape = autoescape））”

当我低于1.9时，此代码有效，但是随着我最近移至django 2.2，它开始出现此错误。似乎要对Django版本进行更改。

下面是详细代码。

def django_165_urlize_impl(text, trim_url_limit=None, nofollow=False, autoescape=False, newtab=True):
"""
Implementation is from Django 1.6.5 -- modified to add target='blank_'
Converts any URLs in text into clickable links.
Works on http://, https://, www. links, and also on links ending in one of
the original seven gTLDs (.com, .edu, .gov, .int, .mil, .net, and .org).
Links can have trailing punctuation (periods, commas, close-parens) and
leading punctuation (opening parens) and it'll still do the right thing.

If trim_url_limit is not None, the URLs in link text longer than this limit
will truncated to trim_url_limit-3 characters and appended with an elipsis.

If nofollow is True, the URLs in link text will get a rel="nofollow"
attribute.
If autoescape is True, the link text and URLs will get autoescaped.
