redis缓存 flask

在Flask中使用Redis缓存可以通过flask-redis插件来实现。下面是使用flask-redis实现Redis缓存的步骤：

1.安装flask-redis插件

pip install flask-redis

2.在Flask应用程序中配置Redis

from flask import Flask
from flask_redis import FlaskRedis

app = Flask(__name__)
app.config['REDIS_URL'] = 'redis://localhost:6379/0'
redis_store = FlaskRedis(app)

3.使用Redis缓存数据

from flask import Flask
from flask_redis import FlaskRedis

app = Flask(__name__)
app.config['REDIS_URL'] = 'redis://localhost:6379/0'
redis_store = FlaskRedis(app)

@app.route('/')
def index():
    # 设置缓存
    redis_store.set('name', 'Tom')
    # 获取缓存
    name = redis_store.get('name')
    return name

4.使用Redis缓存视图函数的返回值

from flask import Flask
from flask_redis import FlaskRedis
from flask_caching import Cache

app = Flask(__name__)
app.config['REDIS_URL'] = 'redis://localhost:6379/0'
redis_store = FlaskRedis(app)
cache = Cache(app, config={'CACHE_TYPE': 'redis', 'CACHE_REDIS_URL': 'redis://localhost:6379/0'})

@app.route('/')
@cache.cached(timeout=60)
def index():
    return 'Hello World!'
