在setting中ROOT_URLCONF = ‘devops.urls‘ 配置
Django如何处理请求
匹配url，都是从第一个往下匹配，若第一个可以匹配，就不用跳到第二个url规则
from django.conf.urls import url,includefrom . import viewsapp_name = ‘dashboard‘urlpatterns = [ ???url(r‘^$‘, views.index,name=‘index‘), ???url(r‘^login/$‘, views.loginView,name=‘login‘), ???????url(r‘^login/‘, views.loginView1,name=‘login1‘),]每个正则表达式前面的‘r‘ 是可选的但是建议加上。 它告诉Python 这个字符串是“原始的” ，表示：字符串中任何字符都不应该转义。
url映射一般是一条正则表达式，“^” 字符串的开始，“$“ 字符串的结束
例子1：访问“http://127.0.0.1:8000/dashboard/login/123” 匹配的是 ?url(r‘^login/‘, views.loginView1,name=‘login1‘) 这条
???????????: ?访问“http://127.0.0.1:8000/dashboard/login” ?匹配的是 ?url(r‘^login/$‘, views.loginView,name=‘login‘) 这条例子2：
from django.conf.urls import urlfrom . import viewsurlpatterns = [ ???url(r‘^articles/2003/$‘, views.special_case_2003), ???url(r‘^articles/([0-9]{4})/$‘, views.year_archive), ???url(r‘^articles/([0-9]{4})/([0-9]{2})/$‘, views.month_archive), ???url(r‘^articles/([0-9]{4})/([0-9]{2})/([0-9]+)/$‘, views.article_detail),]匹配第一个：
访问：“http://127.0.0.1:8000/dashboard/articles/2003/”
匹配第二个：
访问：“http://127.0.0.1:8000/dashboard/articles/2013/”
匹配第三个：
访问：“http://127.0.0.1:8000/dashboard/articles/2013/12/”
匹配第四个：
访问：“http://127.0.0.1:8000/dashboard/articles/2014/12/12312123123213/”
def article_detail(request,*args,**kwargs): ???print("args:",args) ???print("kwargs:",kwargs) ???return HttpResponse(‘12‘)结果：args: (‘2014‘, ‘12‘, ‘12312123123213‘)kwargs: {}关键字参数
from django.conf.urls import urlfrom . import viewsurlpatterns = [ ???url(r‘^articles/2003/$‘, views.special_case_2003), ???url(r‘^articles/(?P<year>[0-9]{4})/$‘, views.year_archive), ???url(r‘^articles/(?P<year>[0-9]{4})/(?P<month>[0-9]{2})/$‘, views.month_archive), ???url(r‘^articles/(?P<year>[0-9]{4})/(?P<month>[0-9]{2})/(?P<day>[0-9]{2})/$‘, views.article_detail),]url(r‘^articles/(?P<year>[0-9]{4})/(?P<month>[0-9]{2})/(?P<day>[0-9]{2})/$‘, views.article_detail),def article_detail(request,*args,**kwargs): ???return HttpResponse(json.dumps(kwargs))结果：
include访问：
urlpatterns = [ ?????url(r"^user/", include([ ?????????url(r‘^list/$‘, view.userlist, name="user_list"), ?????????url(r‘^info/$‘, view.userinfo, name="userer_inf), ?????????url(r‘^modify/‘, include([ ????????????url(r‘status/$‘,view.modifystatus, name="user_modify_status"), ?????????])) ?????]))]访问：‘http://127.0.0.1:8000/user/list/’ ???????????????????‘http://127.0.0.1:8000/user/info/’ ???????????????????‘http://127.0.0.1:8000/user/modify/’ ???????????????????????????????‘http://127.0.0.1:8000/user/modify/status/’类视图
以函数的形式进行定义的视图就是函数视图
以类的的形式进行定义的视图就是类视图
例子：展示页面的增删改查功能
用函数视图实现：
结果：
用类视图实现：
.as_view() 为类视图提供一个函数入口
url(r‘^login/$‘, views.LoginUser.as_view(),name=‘login‘),
from django.views import View
分页练习：
1、from django.core.paginator import Paginator
2、
class UserViewV4(View): ???def get(self,request,*args,**kwargs): ???????queryset = User.objects.all() ???????paginator = Paginator(queryset,20) ?#20条数据为一页，实例化分页对象 ???????try: ???????????page = int(request.GET.get(‘page‘)) ???????except: ???????????page = 1 ???????if page < 1: ???????????page = 1 ???????page = paginator.page(page) ??#取对象的第几分页对象；page.object_list：为第几分页的内容 ???????data = [{‘id‘:user.id,‘email‘:user.email,‘username‘:user.username} for user in page.object_list] ???????return JsonResponse(data,safe=False)例子2：
通过给定的接口创建普通用户密码
class UserViewV5(View): ???def post(self,request,*args,**kwargs): ???????data = request.POST.dict()#接收所有的dict ???????print(data) ????????try: ???????????user = User.objects.create_user(**data) ???????except IntegrityError: ???????????return JsonResponse({‘error‘:‘用户已存在‘}) ???????return JsonResponse({‘id‘:user.id,‘email‘:user.email,‘username‘:user.username})create_user接收的参数，data那里必须要对应起来，不然添加不了，：
