# Mo-Cache
a simple cache lib support memory、file、redis
Github: https://github.com/mouday/mo-cache
## install
```bash
pip install mo-cache
```
## demo
快速开始
```python
from mo_cache import MemoryCache
cache = MemoryCache()
# 此时的key默认是函数名 foo
@cache
def foo(a, b):
return a + b
if __name__ == '__main__':
foo()
```
## 更多示例
1、使用装饰器
```python
# 主动设置key, 过期时间单位：秒s
@cache(key='custom_key', expire=30)
def foo(a, b):
return a + b
```
2、主动设置和获取
```python
cache.set(key='custom_key', value='value', expire=30)
value = cache.get(key='custom_key')
```
MemoryCache, FileCache, RedisCache实现了共同的接口(set/get/call)，
只是构造参数稍有不同
```python
from mo_cache import MemoryCache, FileCache, RedisCache
memory_cache = MemoryCache()
file_cache = FileCache(cache_dir='cache')
redis_cache = RedisCache(redis_url='redis://localhost:6379/0')
```
## 继承体系
```python
class CacheAbstract(object):
"""统一的接口"""
def set(self, key, value, expire=-1):
pass
def get(self, key):
pass
class CacheDecorator(CacheAbstract):
"""cache 装饰器"""
def __call__(self, key=None, expire=-1):
pass
class MemoryCache(CacheDecorator):
"""内存缓存"""
class FileCache(CacheDecorator):
"""文件缓存"""
class RedisCache(CacheDecorator):
"""Redis 缓存"""
```
