py django

创建项目

$ django-admin startproject server

运行项目

$ cd server
$ python manage.py runserver

创建一个模块

$ python manage.py startapp api

设置控制器

api/views.py:

import json

from django.http import HttpResponse, JsonResponse

def main(request):
  return HttpResponse('hello world.')

def cat(request):
  return JsonResponse({'message': 'cat.'})

def dog(request):
  return HttpResponse(json.dumps({'message': "dog."}), content_type='application/json')

配置api模块的路由(Urls)

api/urls.py:

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

urlpatterns = [
  path('', views.main, name='main'),
  path('cat', views.cat, name='cat'),
  path('dog', views.dog, name='dog')
]

将api控制器导入主模块中

server/urls.py

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

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

启动服务器后访问: http://127.0.0.1:8000/api http://127.0.0.1:8000/api/cat http://127.0.0.1:8000/api/dog
