urls的使用

• 首先根据昨天的代码修改主urls.py文件

from django.conf.urls import url,include
from django.contrib import admin
from testapp import views

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^login/$', views.login),
    url(r'^api/',include('testapp.urls'))
]

• 这里我们使用include，调用testapp的urls文件
• 编辑testapp项目的urls文件

from django.conf.urls import url,include
from django.contrib import admin
from testapp import views

urlpatterns = [
    url(r'^list.html', views.list),
    url(r'^add.html', views.add),
    url(r'^update.html', views.update),
    url(r'^delete.html', views.delete),
]

• 编辑testapp的views.py文件

from django.shortcuts import render,HttpResponse,redirect
from testapp import models

def login(requests):
    pass
def list(request):
    return HttpResponse('this list')
def add(request):
    return HttpResponse('this add')
def update(request):
    return HttpResponse('this update')
def delete(request):
    return HttpResponse('this delete')

• 在浏览器中访问就可以看到正确的返回了

urls的补充

• 编辑testapp的urls.py

from django.conf.urls import url,include
from django.contrib import admin
from testapp import views

urlpatterns = [
    url(r'^list.html', views.list),
    url(r'^add.html', views.add),
    url(r'^(?P<num>[0-9]+)/update.html', views.update),
    url(r'^delete.html', views.delete),
]

• 传递num到views

def update(request,num):
    print(num)
    return HttpResponse('this update')

• 通过网页访问http://127.0.0.1:8000/api/1/update.html/

返回的结果和以前一样，但是日志中会打印1
