pycasbin redis watcher

Casbin角色监视器，用于监视Casbin策略的更新

安装

pip install pycasbin-redis-watcher

基本用法

示例使用 https://github.com/ScienceLogic/pycasbin/flask-authz

from flask_authz import CasbinEnforcer
from casbin_redis_watcher import RedisWatcher
casbin_enforcer = CasbinEnforcer(app, adapter)
watcher=RedisWatcher(redis_hostname, redis_port)
watcher.set_update_callback(casbin_enforcer.e.load_policy)
casbin_enforcer.set_watcher(watcher)

与UWSGI一起使用

此redis-watcher模块启动单独的进程，这些进程订阅Redis通道，并监听该通道上的Casbin策略更新。当在WSGI上下文（如uwsgi）中运行时，您可能希望将这些进程作为postfork操作启动。如下所示

try:
    from uwsgidecorators import postfork
    print("Running in uwsgi context")
except ModuleNotFoundError:
    print("Not running in uwsgi context")
    postfork = None

if postfork:
    @postfork
    def load_watcher():
        global casbin_enforcer
        watcher = RedisWatcher(redis_info.hostname, redis_info.port)
        watcher.set_update_callback(casbin_enforcer.e.load_policy)
        casbin_enforcer.set_watcher(watcher)
