rest_framework自定义认证

rest_framework自定义认证，简单两步即可实现
下面是所有views urls models 的代码

#views.py

from django.shortcuts import render
from django.http import HttpResponse,JsonResponse
from rest_framework.views import APIView
from rest_framework.request import Request

from rest_framework.authentication import BasicAuthentication
from . import models

def md5(user):
'''生成md5随机字符串'''
import hashlib
import time
ctime=str(time.time())
m=hashlib.md5(bytes(user,encoding='utf-8'))
m.update(bytes(ctime,encoding='utf-8'))
return m.hexdigest()

ORDER_DICT={
1:{
'name':'狗头',
'age':'18',
'sex':'男',
'content':'.....'
},
2:{
'name':'毛毛',
'age':'99',
'sex':'女',
'content':'.....'
},
}

return HttpResponse('ok')

'''

# 创建token表
token=md5(user)

# 创建或更新token

ret['token']=token
else:
ret['code']=1004
ret['msg']='账号或密码错误'
except Exception as e:

return JsonResponse(ret)

return (token_obj.user,token_obj)

# 必写这个函数，
