Python Django 前后端分离 API的方法（python培训）

# 创建一个app
startapp ulb_manager


settings.py 文件中 设置
INSTALLED_APPS = [
 # 加入这句话
 'apps.ulb_manager',
]

MIDDLEWARE_CLASSES = [
 # 关闭掉跨域的一些验证，注释掉下面这句话
 # 'django.middleware.csrf.CsrfViewMiddleware',

]

from django.conf.urls import url
from django.contrib import admin
from apps.ulb_manager.views import apis

urlpatterns = [
 url(r'^admin/', admin.site.urls),
 url(r'^api', apis),
]

# Create your views here.
from apps.message.models import UserMessage


def apis(request):
 if request.method == "POST":
  name = request.POST.get("name", "")
  all_messages = UserMessage.objects.filter(name=name)
 else:
  # 例子
  name = request.GET.get("name", "")
  all_messages = UserMessage.objects.all()
 resultList = []
 for message in all_messages:
  resultList += [{
   "username": message.name,
   "address": message.address,
  }]
 # 返回值
 response = JsonResponse(resultList, safe=False)
 # response.status_code = 500 自定义响应码
 return response
