简单的基于 redis 的缓存，用于存储 python 函数调用的结果、json 编码的字符串或 html .zip

# redis-simple-cache redis-simple-cache is a pythonic interface for creating a cache over redis. It provides simple decorators that can be added to any function to cache its return values. Requirements: ------------- redis 2.6.2 redis-py 2.7.1 (see requirements.txt file) Installation: ------------- pip install redis-simple-cache or to get the latest version git clone git://github.com/vivekn/redis-simple-cache.git cd redis-simple-cache python setup.py install Usage: ------ from redis_cache import cache_it_json @cache_it_json(limit=1000, expire=60 * 60 * 24) def fib(n): if n == 0: return 0 elif n == 1: return 1 else: return fib(n-1) + fib(n-2) `limit` is the maximum number of keys, `expire` is the expire time in seconds. It is always recommended to specify a expire time, since by default redis-server will only remove keys with an expire time set in a event of full memory. But if you wish your keys to never expire, set `expire` to `None`. **Note that function arguments and result must be pickleable, since cache_it uses the pickle module.** It is also possible to use redis-simple-cache as a object-oriented cache: >> from redis_cache import SimpleCache >> c = SimpleCache(10) # cache that has a maximum limit of 10 keys >> c.store("foo", "bar") >> c.get("foo") 'bar' >> "foo" in c # efficient membership test, time-complexity O(1) True >> len(c) # efficient cardinality calculation, time-complexity O(1) 1 >> c.keys() # returns all keys, time-complexity O(N) with N being the cache c cardinality set(['foo']) >> c.flush() # flushes the cache, time-complexity O(N) with N being the cache c cardinality >> "foo" in c False >> len(c) 0 Check out more examples in the test_rediscache.py file. Advanced: --------- Advanced users can customize the decorators even more by passing a SimpleCache object. For example: my_cache = SimpleCache(limit=100, expire=60 * 60, hashkeys=True, host='localhost', port=6379, db=1, namespace='Fibonacci') @cache_it(cache=my_cache) def fib(n): # ... `hashkeys` parameter makes the SimpleCache to store keys in md5 hash. It is `True` by default in decorators, but `False` by default in a new SimpleCache object. `host`, `port` and `db` are the same redis config params used in StrictRedis class of redis-py. By default, the `namespace` is the name of the module from which the decorated function is called, but it can be overridden with the `namespace` parameter.
