PyCasbin的异步Redis适配器

Async Redis Adapter是PyCasbin的异步redis适配器。使用这个库，Casbin可以从redis加载策略或将策略保存到其中。

安装

pip install casbin_async_redis_adapter

简单示例

import asyncio
from casbin_async_redis_adapter import Adapter
import casbin


async def get_enforcer():
    adapter = Adapter("localhost", 6379, encoding="utf-8")
    e = casbin.AsyncEnforcer("rbac_model.conf", adapter)
    model = e.get_model()

    model.clear_policy()
    model.add_policy("p", "p", ["alice", "data1", "read"])
    await adapter.save_policy(model)

    model.clear_policy()
    model.add_policy("p", "p", ["bob", "data2", "write"])
    await adapter.save_policy(model)

    model.clear_policy()
    model.add_policy("p", "p", ["data2_admin", "data2", "read"])
    await adapter.save_policy(model)

    model.clear_policy()
    model.add_policy("p", "p", ["data2_admin", "data2", "write"])
    await adapter.save_policy(model)

    model.clear_policy()
    model.add_policy("g", "g", ["alice", "data2_admin"])
    await adapter.save_policy(model)

    e = casbin.AsyncEnforcer("rbac_model.conf", adapter)
    await e.load_policy()

    return e


sub = "alice"  # the user that wants to access a resource.
obj = "data1"  # the resource that is going to be accessed.
act = "read"  # the operation that the user performs on the resource.


async def main():
    e = await get_enforcer()
    if e.enforce("alice", "data1", "read"):
        print("alice can read data1")
    else:
        print("alice can not read data1")


asyncio.run(main())

配置

Adapter()默认启用decode_responses并支持任何Redis参数配置。

要使用casbin_redis_adapter，您必须提供以下参数配置

• host：redis服务的地址
• port：redis服务端口

以下参数默认提供

• db：redis数据库，默认为0
• username：redis用户名，默认为None
• password：redis密码，默认为None
