1.目录结构

2.urls.py

from django.conf.urls import url
from django.contrib import admin
from app02 import views as app02_view

urlpatterns = [
    url(r‘^admin/‘, admin.site.urls),
    url(r‘^hosts/‘,app02_view.HostView.as_view()),
    url(r‘^auth/$‘,app02_view.AuthView.as_view())
]

3.models.py

from django.db import models

# Create your models here.

class Userinfo(models.Model):
    username = models.CharField(max_length=32)
    password = models.CharField(max_length=64)

    token = models.CharField(max_length=64,null=True)

4.views.py

from django.shortcuts import render,HttpResponse
from rest_framework.views import  APIView
from rest_framework.request import Request
from rest_framework.exceptions import APIException
from rest_framework.response import Response
import time
import hashlib
# Create your views here.

from app02 import models

# class MyAuthentication(object):
#     def authenticate(self,request):
#         token = request.query_params.get(‘token‘)
#         if token == ‘ASSDSA‘:
#             return (‘uuuuuuuuuuu‘,‘aaaaaaaaaaa‘)
#         raise  APIException(‘认证失败‘)

        m = hashlib.md5()
        m.update(key.encode(‘utf-8‘))
        token = m.hexdigest()
        #保存到数据
        user_obj.token = token
        user_obj.save()

        ret[‘token‘] = token
        return Response(ret)

class HostView(APIView):

    def get(self,request,*args,**kwargs):

        self.dispatch
        print(request.user)
        print(request.auth)
        return Response(‘主机列表‘)

5.utils.py

from django.shortcuts import render,HttpResponse
from rest_framework.views import  APIView
from rest_framework.request import Request
from rest_framework.exceptions import APIException
from rest_framework.response import Response
from app02 import models

        if obj:
            return obj(obj.username,obj)
        raise  APIException(‘用户认证认证失败‘)

6.settings.py

RESTFRAMEWORK  = {
    ‘UNAUTHENTICATED_USER‘:None,
    ‘UNAUTHENTICATED_TOKEN‘:None,
    "DEFAULT_AUTHENTICATION_CLASSES":[
        "app02.utils.MyAuthentication",
