本地开发过程中经常要查看内容写没写到memcache中，一般看一下memcache中有没有想对应的key就好了，懒得用telnet连接memcache，自带的memcached-tool输出又不怎么方便阅读，so 写了一个简单的查看memcache中key的python小程序

 6 class MemcacheServer(object):

10     def connect(self, host=None, port=None):
11         self.host = host
12         self.port = port
13         try:
14             self.server.connect((host, port))
15         except:
16             print "connect error ......"

19     def send(self, msg):
20         self.server.send(msg)

22     def get_msg(self):
23         buf_len = 1024
24         msg = u""
25         while True:
26             buf = self.server.recv(buf_len)
27             msg += buf
28             if len(buf)!=buf_len:
29                 break

41         if match:
