如何获取此字符串的正确正则表达式？

Question

下面是一些文本，当我把它作为参数传递给description（包括后面的返回字符和url）时，它不起作用。我在django做这个。你知道吗

partner/BuzzFeed/fXkqhhIlOtA/NY Yankees: 6 Essential Pieces of Postseason Memorabilia/The National Baseball Hall of Fame shows off 6 pieces of Yankees postseason memorabilia: a watch from the 1923 World Series; Babe Ruth's bat from the 1926 World Series; Yogi Berra's glove from Don Larsen's perfect game in 1956; the last out ball in the 1962 World Series; Derek Jeter's jersey from the 1996 World Series; Mariano Rivera's hat from the 2000 Subway Series. http://www.buzzfeed.com/sports/

urlpatterns = patterns('reserve.views',
    url(r'^partner/(?P<partner_name>[-\w]+)/$', 'partner_channel'),
    url(r'^partner/(?P<author>[-\w]+)/(?P<video>[-\w]+)/$', 'video_player'),
    url(r'^partner/(?P<author>[-\w]+)/(?P<video>[-\w]+)/(?P<title>.+)/(?P<desc>.+)/$', 'video_player'),
    url(r'^category/(?P<category>[-\w]+)/$', 'all_partners'),
    url(r'^admin/', include(admin.site.urls)),
)

如何更改desc参数的regex以允许此操作？你知道吗

Answer 1

给它s选项。默认情况下，.匹配除新行以外的任何字符。另外，你需要使你的标题部分不贪婪，因为否则它将匹配你的整个描述。使用.+?而不是.+这样做。你知道吗

Answer 2

您的urlpatterns正在被覆盖（可能是不正确的）。有两个模式匹配“video\u player”，但没有一个模式匹配“desc”：

url(r'^partner/(?P<author>[-\w]+)/(?P<video>[-\w]+)/$', 'video_player'),
url(r'^partner/(?P<author>[-\w]+)/(?P<video>[-\w]+)/(?P<title>.+)/(?P<desc>.+)/$', 'video_player'),

将上面的最后一个url标识符更改为“视频播放器”以外的内容。你知道吗

Answer 3

问题是你的标题匹配是贪婪的，匹配的比你想要的多，并且分隔你的部分的/被包含在标题中，描述是最后一个/（在url中）之后的所有内容

将其更改为非贪婪(?P<title>.+?)

url(r'^partner/(?P<author>[-\w]+)/(?P<video>[-\w]+)/(?P<title>.+?)/(?P<desc>.+)/$', 'video_player'),
