urls

容易搞混的概念，域名，主机名，路由

网站模块多主机应用

不同模块解析不同的服务器ip地址

网页模块多路径应用

urlpatterns = [
path(‘admin/’, admin.site.urls),
path(‘’, app01views.index),
path(‘movie/’, app01views.movie),
path(‘movie/int:movie_id/’, app01views.movie_detail)
]

url传值

urlpatterns = [
path(‘admin/’, admin.site.urls),
path(‘’, app01views.index),
path(‘movie/’, app01views.movie),
path(‘movie/int:movie_id/’, app01views.movie_detail)
]

使用url中查询字符串传值

def movie_detail(request):
movie_id = request.GET.get(“movieid”)
city = request.GET.get(“city”)
return HttpResponse(“正在播放编号为：%s的电影, 城市：%s” % (movie_id,city))

path(‘movie/detail/’, app01views.movie_detail),

re_path

re_path(‘movie/detail/(?P<movie_id>[9][5]\d{4})/(?P[0-4])’,app01views.movie_detail)

def movie_detail(request, movie_id, type):
type_name = [“喜剧片”, “动作片”, “爱情片”, ‘纪录片’, ‘历史剧’]
return HttpResponse(“正在播放电影编号为：%s的电影！ \n 播放的电影类型：%s” %
(movie_id,type_name[int(type)]))
