Django Redis存储session会话

 

通常redis都是用来保存session、短信验证码、图片验证码等数据。

在django上使用redis，先要安装一个包：

pip install django-redis==4.8.0(我用的django是1.11.1版本)

在settings上配置：

CACHES = {
    "default": {
        "BACKEND": "django_redis.cache.RedisCache",
        "LOCATION": "redis://192.168.8.102:6379/0",
        "OPTIONS": {
            "CLIENT_CLASS": "django_redis.client.DefaultClient",
        }
    },
    "session": {
        "BACKEND": "django_redis.cache.RedisCache",
        "LOCATION": "redis://192.168.8.102:6379/1",
        "OPTIONS": {
            "CLIENT_CLASS": "django_redis.client.DefaultClient",
        }
    },
    "sms_codes": {
        "BACKEND": "django_redis.cache.RedisCache",
        "LOCATION": "redis://192.168.8.102:6379/2",
        "OPTIONS": {
            "CLIENT_CLASS": "django_redis.client.DefaultClient",
        }
    }
}

# 保存 session数据到 Redis中
SESSION_ENGINE = "django.contrib.sessions.backends.cache"
SESSION_CACHE_ALIAS = "session"

在视图中使用：

# 在redis上查看存储的会话

# 2) ":1:django.contrib.sessions.cachehdrgn4pbtnylv23241089a4ajfkh8f4f"

import json
from django_redis import get_redis_connection

con = get_redis_connection("sms_codes")  #con就是StrictRedis类型，default对应settings.py中CACHES中设置的sms_codes。

# dict序列化字符串存储到redis
name = "zhangsan"
val = {"is_login": "True", "username": "zhangsan"}
res = con.set(name, json.dumps(val))

# 从redis取数据
# res = eval(con.get("zhangsan").decode("utf-8"))
res =con.get(name)
print(res)
