1.DRF认证组件之视图注册用法(自定义简单使用)

　　settings.py配置　　

INSTALLED_APPS = [

    'django.contrib.admin',

    'django.contrib.auth',

    'django.contrib.contenttypes',

    'django.contrib.sessions',

    'django.contrib.messages',

    'django.contrib.staticfiles',

    'app01.apps.App01Config',

    'rest_framework',

]

seetings.py

　　urls.py:　　

from django.conf.urls import url

from django.contrib import admin

from app01 import views

urlpatterns = [

    url(r'^admin/', admin.site.urls),

    url(r'^book/', views.CourseView.as_view(),name='courses'),

]

urls.py

　　veiws.py

from django.shortcuts import render, HttpResponse

from rest_framework.views import APIView

from rest_framework import exceptions

# Create your views here.

#实例url:http://127.0.0.1:8000/book/?token=1

class MyAuth(object):

    def authenticate(self, request):

        # 该示例认证是需要在请求的url加上参数token（实际直接是校验用户名或密码或者登陆标识等）

        token = request._request.GET.get('token')

        if not token:

            raise exceptions.AuthenticationFailed('未认证用户！！！')

        return ('认证通过的request.user', 'request.auth')  # 认证函数执行结果如果通过则为元组，元组第一个元素封装在为request.user，第二个参数封装在request.auth中

    def authenticate_header(self, request):

        pass

class CourseView(APIView):

    # 认证组件

    authentication_classes = [MyAuth, ]

    def get(self, request):

        print(request.user)#request.user在APIViewD的dispatch中进行封装的

        return HttpResponse('GET')

    def post(self, request):

        return HttpResponse('POST')

    def put(self, request):

        return HttpResponse('PUT')

    def patch(self, request):

        return HttpResponse('PATCH')

    def delete(self, request):

        return HttpResponse('DELETE')

veiws.py

2.DRF认证组件的使用（局部和全局）

方式一：局部配置---视图类中添加类变量    authentication_classes=[MyAuth,]---（认证类列表）

　　

　　settings.py配置见上（注册rest_framework应用） 　　

　　models.py　　

from django.db import models

# Create your models here

class UserInfo(models.Model):

    """

    用户表

    """

    user_type_choices = [

        (1, '普通用户'),

        (2, 'VIP用户'),

        (3, 'SVIP用户'),

    ]

    user_type = models.IntegerField(choices=user_type_choices)

    username = models.CharField(max_length=10, unique=True)

    password = models.CharField(max_length=12, null=False)

class UserToken(models.Model):

    """

    token表

    """

    user = models.OneToOneField(to='UserInfo')

    token = models.CharField(max_length=64)

    create_time = models.DateTimeField(auto_now=True)

class Book(models.Model):

    name = models.CharField(max_length=12)

models.py

　　urls.py　　

from django.conf.urls import url

from django.contrib import admin

from app01 import views

urlpatterns = [

    url(r'^admin/', admin.site.urls),

    url(r'^api/v1/login', views.AuthView.as_view()),

    url(r'^book/', views.CourseView.as_view(),name='courses'),

]

urls.py

　　views.py　　

from django.shortcuts import render, HttpResponse

from rest_framework.views import APIView

from rest_framework import exceptions

from app01 import models

from django.http import JsonResponse

# Create your views here.

# 实例url:http://127.0.0.1:8000/book/?token=1

#认证类，每个类使用都需要加上类变量参数authentication_classes = [MyAuth, ]

class MyAuth(object):

    def authenticate(self, request):

        # 该示例认证是需要在请求的url加上参数token（实际直接是校验用户名或密码或者登陆标识等）

        token = request._request.GET.get('token')

        token_obj = models.UserToken.objects.get(token=token)

        if not token_obj:

            raise exceptions.AuthenticationFailed('未认证用户！！！')

        return (token_obj.user, 'request.auth')  # 认证函数执行结果如果通过则为元组，元组第一个元素封装在为request.user，第二个元素封装为request.auth

    def authenticate_header(self, request):

        pass

class CourseView(APIView):

    # （1）认证组件

    authentication_classes = [MyAuth, ]

    def get(self, request):

        print(request.user)  # request.user在认证组件中进行封装的

        return HttpResponse('GET')

    def post(self, request):

        return HttpResponse('POST')

    def put(self, request):

        return HttpResponse('PUT')

    def patch(self, request):

        return HttpResponse('PATCH')

    def delete(self, request):

        return HttpResponse('DELETE')

import time

import hashlib

def token_md5(username):

    """

    自定义token

        ret = {'code': 0, 'msg': ''}

        print(request._request.POST)

        username = request._request.POST.get('username', None)

        # 每次登陆如果有就更新没有就创建

        try:

views.py

方式二：全局配置----在settings.py配置文件中加载REST_FRAMEWORK配置

　　

　　settings.py　　

INSTALLED_APPS = [

    'django.contrib.auth',

    'django.contrib.contenttypes',

3.DRF认证组件的继承类(常用)

　　

　　utils--auth.py--MyAuth认证类　　

from rest_framework import exceptions

from app01 import models

from rest_framework.authentication import BaseAuthentication,BasicAuthentication

# 实例url:http://127.0.0.1:8000/book/?token=1

#认证类（可以定义多个）:

    # 方式一：每个类使用都需要加上类变量参数authentication_classes = [MyAuth, ]

    #方式二：在setings.py配置中加载REST_FRAMEWORK配置----'DEFAULT_AUTHENTICATION_CLASSES' : [],

# class MyAuth(object):

class MyAuth(BaseAuthentication):#可以直接继承BaseAuthentication类，可以省略authenticate_header方法，或者继承BasicAuthentication

    def authenticate(self, request):

        # 该示例认证是需要在请求的url加上参数token（实际直接是校验用户名或密码或者登陆标识等）

        token = request._request.GET.get('token')

        token_obj = models.UserToken.objects.get(token=token)

        if not token_obj:

            raise exceptions.AuthenticationFailed('未认证用户！！！')

        return (token_obj.user', 'request.auth')  # 认证函数执行结果如果通过则为元组，元组第一个元素封装在为request.user

    # def authenticate_header(self, request):

    #     pass

utils--auth.py--MyAuth认证类

　　settings.py

INSTALLED_APPS = [

    'django.contrib.admin',

    'django.contrib.auth',

    'django.contrib.contenttypes',

    'django.contrib.sessions',

    'django.contrib.messages',

    'django.contrib.staticfiles',

    'app01.apps.App01Config',

    'rest_framework',

]

REST_FRAMEWORK = {

#认证组件

    'DEFAULT_AUTHENTICATION_CLASSES' : ['app01.utils.auth.MyAuth',],#可以自定义多个认证类

    'UNAUTHENTICATED_USER':lambda :'匿名用户request.user自定义值',#request.user有默认值，可以直接写None
