我试图传递一些变量,但我遇到了一些麻烦,特别是有3个问题。 如何对url字符串进行编码以考虑字符串中的特殊字符? 鉴于字符串,我应该使用的正确正则表达式是什么? 我如何解码已编码的网址?
author = 'foo'
video = 'bar123-456'
title = 'Santorum: "I'm Not a Visionary"' # in my version, it is referencing another variable so the syntax error doesn't occur. But I left it in here because I want to know how to deal with " and '.
related = 'http://gdata.youtube.com/feeds/api/users/haha/uploads?v=2&max-results=50'
url = urllib.quote('partner/' + author+ '/'+ video+'/'+ title + '/' + related)
#How do I encode this url string above to take into account the special characters in the string?
<a href="/{{url}}" > <img src="img.png" > </a>
url(r'^partner/(?P<partner_name>[-\w]+)/(?P<video_id>[-\w]+)/(?P<video_title>[-\w]+)//(?P<related_feed>)/$', 'video_player'),
#do I have to add anything to the regex?
def video_player(request, author, video, related):
#how do I decode the urls that are encoded
我尝试了它没有相关性,看看它是否有效,但仍然出现错误。
模板:
<a href="{% url 'reserve.views.video_player' author video title %}" >
URL:
url(r'^partner/(?P<author>[-\w]+)/(?P<video>[-\w]+)/(?P<title>[-\w]+)/$', 'video_player'),
我收到此错误:
/ partner / BuzzFeed的NoReverseMatch / 反向''video_player''带有参数'('BuzzFeed','fXkqhhIlOtA','NY Yankees:6个基本的季后赛纪念品')'和关键字参数'{}'找不到。
urlpatterns = patterns('reserve.views',
url(r'^$', 'index'),
url(r'^browse/$', 'browse'),
url(r'^faq/$', 'faq'),
url(r'^about/$', 'about'),
url(r'^contactinfo/$', 'contactinfo'),
url(r'^search/$', 'search'),
(r'^accounts/', include('registration.backends.default.urls')),
(r'^accounts/profile/$', 'profile'),
(r'^accounts/create_profile/$', 'user_profile'),
(r'^accounts/edit_profile/$', 'edit_profile'),
url(r'^products/(?P<product_name>[-\w]+)/reviews/$', 'view_reviews'),
url(r'^products/(?P<product_id>\d+)/reviews/$', 'view_reviews'),
url(r'^user/(?P<user_id>[-\w]+)/$', 'view_reviews_user'),
#url(r'^category/(?P<category_name>[-\w]+)/$', 'view_product_category'),
url(r'^partner/(?P<partner_name>[-\w]+)/$', 'partner_channel'),
url(r'^partner/(?P<author>[-\w]+)/(?P<video>[-\w]+)/(?P<video_title>[-\w]+)/$', 'video_player'),
url(r'^partner/(?P<author>[-\w]+)/(?P<video>\w+)/(?P<title>\w+)/$', 'video_player'),
url(r'^admin/', include(admin.site.urls)),
)

将这些变量原样传递给模板,使用url,然后发送到模板,只需在视图中执行此操作。
<强> View.py 强>
related = urllib.quote(related, safe='')
<强>模板强>
<a href="{% url 'path.to.video_player' author video related %}" > <img src="img.png" > </a>
<强> Url.py 强>
url(r'^partner/(?P<author>[-\w]+)/(?P<video>\w+)/(?P<related>\w+)/$', 'video_player'),
修改强>
如果您想要没有相关参数,或者如果有疑问,视频也可以是无,那么只需在您的视图中执行此操作:
def video_player(request, author, video=None, related=None):
现在你可以使用网址
了<a href="{% url 'path.to.video_player' author video %}" > <img src="img.png" > </a>

在较新版本的python中,您只需键入: 示例:
path('<int:id>/delete/', delete_view, name = 'delete'),
