set
set在memcached中添加一个key->value，如果这个key之前已经存在，那么就会替换，否则就是添加
语法： set <key> 0(是否需要压缩) 60(过期时间s) 6(字符的长度)
#设置username的值为heboan, 不压缩，过期时间为60s，字符长度为6
set username
heboan
STORED
get
从memecached中根据key来获取值
语法： get <key>
get username
VALUE username
heboan
END
add
add在memcached中添加一个key->value，如果memcached中已经存在了这个key，那么就添加失败，否则添加成功

STORED
add username

NOT_STORED #username已经存在，添加失败
add love STORED #love之前不存在，添加成功
delete
语法： delete <key>
set username
heboan
STORED
delete username #删除username

END
