1. 项目app01
models.py
from django.db import models
from django.contrib.auth.models import AbstractUser
# Create your models here.
class UserProfile(AbstractUser):
"""
用户
"""
name = models.CharField(max_length=30, null=True, blank=True, verbose_name="姓名")
birthday = models.DateField(null=True, blank=True, verbose_name="出生年月")
gender = models.CharField(max_length=6, choices=(("male", u"男"), ("female", "女")), default="female",
verbose_name="性别")
mobile = models.CharField(null=True, blank=True, max_length=11, verbose_name="电话")

verbose_name = "user"
Class Meta:
verbose_name_plural = verbose_name
def __str__(self):
return self.username
serializers.py 序列化文件
# -*- coding: utf-8 -*-
__author__ = 'hyh'
from django.contrib.auth import get_user_model
from rest_framework import serializers
User = get_user_model()
class UserProfileSerializer(serializers.ModelSerializer):
class Meta:
model = User
fields = "__all__"
2.安装djangorestframework-jwt
pip install djangorestframework-jwt
配置settings文件
添加如下配置
import datetime
REST_FRAMEWORK = {
'DEFAULT_AUTHENTICATION_CLASSES': (
#'rest_framework_jwt.authentication.JSONWebTokenAuthentication', # 全局设置
'rest_framework.authentication.BasicAuthentication',
'rest_framework.authentication.SessionAuthentication',
),
}
JWT_AUTH = {
'JWT_EXPIRATION_DELTA': datetime.timedelta(days=7),
'JWT_AUTH_HEADER_PREFIX': 'JWT',
}
AUTH_USER_MODEL = 'app01.UserProfile' # 自定义用户表
AUTHENTICATION_BACKENDS = (
# 将backends添加进setting
'app01.views.CustomBackend',
)
view.py
from django.shortcuts import render
from django.contrib.auth.backends import ModelBackend
from rest_framework import viewsets
from rest_framework import mixins
from rest_framework import authentication
from rest_framework_jwt.authentication import JSONWebTokenAuthentication
from rest_framework_jwt.serializers import jwt_encode_handler, jwt_payload_handler
from django.contrib.auth import get_user_model
from .serializers import UserProfileSerializer
from django.db.models import Q
from rest_framework import status
from rest_framework.views import APIView
from rest_framework.response import Response
from .models import UserProfile
from django.http import JsonResponse
from rest_framework.permissions import IsAuthenticated
from rest_framework import permissions
from app01.utils.permissions import IsOwnerOrReadOnly
# Create your views here.
User = get_user_model()
class CustomBackend(ModelBackend):
"""

"""
def authenticate(self, username=None, password=None, **kwargs):
try:
user = UserProfile.objects.get(Q(username=username)|Q(mobile=username))
if user.check_password(password):
return user
except Exception as e:
return None
class UserViewset(mixins.CreateModelMixin, mixins.UpdateModelMixin, mixins.RetrieveModelMixin,mixins.ListModelMixin, viewsets.GenericViewSet):
serializer_class = UserProfileSerializer
queryset = UserProfile.objects.all()
#permission_classes = (IsAuthenticated, IsOwnerOrReadOnly) # 权限和认证必须同时使用，否则认证不生效

def get_serializer_class(self):
if self.action == "retrieve":
return UserProfileSerializer
elif self.action == "create":

return []
return []
def create(self, request, *args, **kwargs):
serializer = self.get_serializer(data=request.data)
serializer.is_valid(raise_exception=True)
user = self.perform_create(serializer)
re_dict = serializer.data
payload = jwt_payload_handler(user)
re_dict["token"] = jwt_encode_handler(payload)
re_dict["name"] = user.name if user.name else user.username

return serializer.save()
class Index(APIView):
permission_classes = (IsAuthenticated, IsOwnerOrReadOnly)
authentication_classes = (JSONWebTokenAuthentication,)
def get(self,request):
return JsonResponse({"index":"ok"})
3.urls.py
from django.contrib import admin
from django.urls import path
from django.conf.urls import url,include
from rest_framework.routers import SimpleRouter,DefaultRouter
from rest_framework.documentation import include_docs_urls
from app01.views import UserViewset,Index
from rest_framework_jwt.views import obtain_jwt_token
router = SimpleRouter()
router.register('user',UserViewset,base_name='useruinfo')
Urlpatterns = [
path('admin/', admin.site.urls),
url(r'^api-auth/', include('rest_framework.urls', namespace='rest_framework')),
url(r'docs/', include_docs_urls(title="user信息")),
url(r'^login/',obtain_jwt_token),
url(r'^index/',Index.as_view()),
]
urlpatterns += router.urls
4. 在app01下创建utils目录，存放permissions.py文件
permissions.py文件内容
# -*- coding: utf-8 -*-
__author__ = 'hyh'
from rest_framework import permissions
class IsOwnerOrReadOnly(permissions.BasePermission):
"""
Object-level permission to only allow owners of an object to edit it.
Assumes the model instance has an `owner` attribute.
"""
def has_object_permission(self, request, view, obj):
# Read permissions are allowed to any request,
# so we'll always allow GET, HEAD or OPTIONS requests.
if request.method in permissions.SAFE_METHODS:
return True
# Instance must have an attribute named `owner`.
return obj.user == request.user
4.测试
获取token
Copy the token
Return result success
