用memcache处理webpy的session
目前用的webpy0.34里没有对session提供memcache后端，自己参照其它的Store写了一个。
?
import memcache as memcachefrom web.session import Storeclass MemcacheStore(Store): def __init__(self, config): ''' config = { 'servers': ['127.0.0.1:11211'], 'timeout': 1440 } ''' self.mc = memcache.Client(config['servers']) self.timeout = config['timeout'] def __contains__(self, key): return True if self.mc.get(key) else False def __getitem__(self, key): return self.mc.get(key) def __setitem__(self, key, value): self.mc.set(key, value, self.timeout) def __delitem__(self, key): self.mc.delete(key) def cleanup(self, timeout): '''You need nothing to do. Memcache can handle it.''' pass
