day4学习笔记_Django 视图

在不使用模板条件下 配置视图

在views中写入

from django.http import HttpResponse
def index(request):
    return HttpResponse('hello world')

====================================
在project中加入

from django.contrib import admin
from django.urls import path
from django.conf.urls import url, include

urlpatterns = [
    path('admin/', admin.site.urls),
    url(r'^', include('myAPP.urls')),
]

====================================
在project中新建空白python file，名urls

from django.conf.urls import url

#引入需要的视图
from . import views

#设置访问时访问views中的index
urlpatterns = [
    url(r'^$', views.index),
]
'''
    正则文法 
    ^ 限定开头的字符
    $ 限定结束的字符
    + 字符数量大于等于一个
    ()取出括号内的字符
'''
