django中使用Redis

 

方式一

新建一个py文件,在视图类中导入

utils>redis_pool:

import redis
Pool=redis.ConnectionPool(host='127.0.0.1',port=6379,max_connections=100)

views:

from django.shortcuts import render,HttpResponse

# Create your views here.
from redis import Redis
from utils.redis_pool import Pool
conn=Redis(connection_pool=Pool)
def index(request): ret=conn.get('name') print(ret) return HttpResponse('ok')

 方式二:

 在setting中配置

# 安装django-redis模块
  pip3 install django-redis

setting里配置:

# redis配置
CACHES = {
    "default": {
        "BACKEND": "django_redis.cache.RedisCache",
        "LOCATION": "redis://127.0.0.1:6379",
        "OPTIONS": {
            "CLIENT_CLASS": "django_redis.client.DefaultClient",
            "CONNECTION_POOL_KWARGS": {"max_connections": 100}
            # "PASSWORD": "123",
        }
    }
}

views:

from django_redis import get_redis_connection
conn = get_redis_connection('default')
print(conn.hgetall('xxx'))

管道

redis-py默认在执行每次请求都会创建(连接池申请连接)和断开(归还连接池)一次连接操作,

如果想要在一次请求中指定多个命令,则可以使用pipline实现一次请求指定多个命令,并且默认情况下一次pipline 是原子性操作。

import redis
 
pool = redis.ConnectionPool(host='10.211.55.4', port=6379)
 
r = redis.Redis(connection_pool=pool)
 
# pipe = r.pipeline(transaction=False)
pipe = r.pipeline(transaction=True)
pipe.multi()
pipe.set('name', 'alex')
pipe.set('role', 'sb')
 
pipe.execute()
