DRF认证组件

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, ]

    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
    :param username:
    :return:
    """
    t = time.time()
    md5 = hashlib.md5(str(t).encode('utf-8'))
    md5.update(username.encode('utf-8'))
    return md5.hexdigest()

class AuthView(APIView):

    def post(self, request):

        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:
            user_obj = models.UserInfo.objects.filter(username=username, password=password).first()
            if user_obj:
                token = token_md5(username)

        finally:
            return JsonResponse(ret)

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.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'app01.apps.App01Config',
    'rest_framework',
]

REST_FRAMEWORK = {
    '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
    'UNAUTHENTICATED_TOKEN':lambda :'request.auth自定义值',#request.auth有默认值，可以直接写None
}

        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

    user_type = models.IntegerField(choices=user_type_choices)

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
    'UNAUTHENTICATED_TOKEN':lambda :'request.auth自定义值',#request.auth有默认值，可以直接写None
}
