構(gòu)建第二個應用程序

1.打開Visual Studio code

左上角 點擊fike 點擊open folder

2.打開上次的Django項目

并按圖示點擊進入終端

3.在下方終端輸入創(chuàng)建app01項目的命令

接著在左上方會出現(xiàn)一個app01的項目

PS E:\python\Hellodjango> python manage.py startapp  app01

4.接著在Hellodjango的項目里

settings.py中定義應用 找到圖示的行 在末尾添加 app01

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'app01'
]

5.定義app01應用中的views.py視圖文件

無則創(chuàng)建 代碼如下

from django.shortcuts import render
from django.http import HttpResponse

def sayHello(request):
    return HttpResponse("app01 Hello, World!")

6.定義app01中的urls.py

from django.urls import path
from . import views

urlpatterns = [
    path('hello/', views.sayHello)
]

7.定義Hellodjango的urls.py

from django.contrib import admin
from django.urls import path, include
from . import views

urlpatterns = [
    path("admin/", admin.site.urls),
    path('hello/', views.sayHello),
    path('app01/', include('app01.urls'))
]

注意：

• 有些代碼已存在 只需添加沒有的代碼即可 
• 注意格式問題 空格 逗號等

8.在終端輸入啟動web服務的命令

在瀏覽器輸入127.0.0.1:8000/app01/hello/ 進行驗證 效果出現(xiàn)下圖即可

PS E:\python\Hellodjango> python.exe .\manage.py runserver
Watching for file changes with StatReloader
