# 建立app

(python37_django2) D:\python\message_test>python manage.py startapp app

在settings.py中新增app

檢視的建立 app/views.py

方法1：通過get瀏覽器位址列獲取引數

app路由urls

# _*_ coding:utf-8 _*_
 

# __author__ == 'jack'
# __date__ == '2020-12-29 8:27 PM'

from django.urls import path
from .views import LessionTwo

urlpatterns = [
    path('two/ ', LessionTwo.as_view(), name="two")
]

檢視app/views.py

# coding:utf-8

from django.views.generic import View
from django.http import HttpResponse


class
 
 LessionTwo(View):
    def get(self, request):

        message = request.GET.get('message', 'no contains')

        return HttpResponse(message)

在總的urls中引入app的urls

from django.contrib import admin
from django.urls import path,include
from app import urls as app_urls

urlpatterns = [
    path('admin/
 
', admin.site.urls),
    path('', include(app_urls))
]

方法2：

通過resful風格獲取引數

App/views修改

通過路由傳參
