在django中使用Redis訪問session

1.django的快取配置

#

redis在django中的配置
caches =
#"password": "123",
} }
}

#

session的儲存配置
session_engine = '
django.contrib.sessions.backends.cache
'session_cache_alias = '
default'#
設定session失效時間,單位為秒
session_cookie_age = 60*5

from django.conf.urls import

urlfrom django.contrib import
admin
from api import
views
urlpatterns =[
url(r
'^admin/
', admin.site.urls),
url(r
'^session/$
',views.setsession.as_view() ),
]

from rest_framework.views import

apiview
#create your views here.
from rest_framework.response import
response
from api import
models
class
myresponse():
def__init__
(self):
self.status=100self.msg=none
@property
defget_dic(self):
return self.__dict__
class
setsession(apiview):
#設定session,直接request.session就自動把session值儲存到redis中了
defpost(self,request):
response =myresponse()
request.session[
"username
"]="
django
"request.session[
"verify_code
"]="
123"
response.msg="
儲存session成功
"return
response(response.get_dic)
#獲取session,直接從request.session中取session的值
defget(self,request):
response =myresponse()
username_redis=request.session.get("
username")
verify_code_redis=request.session.get("
verify_code")
print
(username_redis,verify_code_redis)
if username_redis=="
django
"and verify_code_redis=="
123"
: response.msg="
驗證成功
"return
response(response.get_dic)
response.msg="
驗證失敗
"response.status=101
return response(response.get_dic)

設定session用了post請求

獲取session用了get請求

需要聯合restframework認證元件一起使用

1.先建立乙個認證類

from rest_framework.authentication import

baseauthentication
from django.core.cache import
cache
from api import
models
from rest_framework.exceptions import
authenticationfailed
class
loginauth(baseauthentication):
defauthenticate(self, request):
token=request.get.get("
token")
#從redis中取出token,前提是已經在settings中配置redis
user=cache.get(token)
ifuser:
return
user,token
token = models.token.objects.filter(key=token).first()
iftoken:
return
token.user,token
else
: 
raise authenticationfailed("
你沒有登入
")

from rest_framework.views import

apiview
from rest_framework.response import
response
from api import
models
from django.core.exceptions import
objectdoesnotexist
from uuid import
uuid4
from django.core.cache import
cache
class
myresponse():
def__init__
(self):
self.status=100self.msg=none
@property
defget_dic(self):
return self.__dict__
class
login(apiview):
defpost(self,request):
response =myresponse()
name=request.data.get("
name")
pwd=request.data.get("
pwd"
) 
try:
user=models.userinfo.objects.filter(username=name,password=pwd).first()
except
objectdoesnotexist as e:
response.msg = "
沒有查收到
"response.status = 101
return
response(response.get_dic)
ifuser:
token=uuid4()
try:
models.token.objects.update_or_create(user=user,defaults=)
#將token存到redis中,設定超時時間一天
cache.set(token, user, 60 * 60 * 24)
response.msg = '
登入成功
'response.token =token
response.name =name
except
objectdoesnotexist as e:
response.msg = "
沒有查收到
"response.status = 101
return
response(response.get_dic)
else
: response.msg = '
使用者名稱或密碼錯誤
'response.status = 101
return response(response.get_dic)

區域性配置:放在檢視函式中

authentication_classes=[loginauth]

全域性配置:settings中
