一、Redis的简单使用

• Redis操作模式

# Author:Li Dongfei
import redis
r = redis.Redis(host='192.168.56.7', port=6379)
r.set('foo', 'bar')
print(r.get('foo'))

• Redis连接池

# Author:Li Dongfei
import redis
pool = redis.ConnectionPool(host='192.168.56.7', port=6379)
r = redis.Redis(connection_pool=pool)
r.set('foo', 'bar')
print(r.get('foo'))

二、string

• set(name, value, ex=None, px=None, nx=False, xx=False)
• setnx(name, value)
• setex(name, value, time)
• psetex(name, time_ms, value)
• mset(*args, **kwargs)
• get(name)
• mget(keys, *args)
• getset(name, value)
• getrange(key, start, end)
• setrange(name, offset, value)
• setbit(name, offset, value)
• bitcount(key, start=None, end=None)
• bitop(operation, dest, *keys)
• strlen(name)
• incr(self, name, amount=1)
• incrbyfloat(self, name, amount=1.0)
• decr(self, name, amount=1)
• append(key, value)

三、hash

• hset(name, key, value)
• hmset(name, mapping)
• hget(name,key)
• hmget(name, keys, *args)
• hgetall(name)
• hlen(name)
• hkeys(name)
• hvals(name)
• hexists(name, key)
• hdel(name,*keys)
• hincrby(name, key, amount=1)
• hincrbyfloat(name, key, amount=1.0)
• hscan(name, cursor=0, match=None, count=None)
• hscan_iter(name, match=None, count=None)

四、list

• lpush(name,values)
• lpushx(name,value)
• llen(name)
• linsert(name, where, refvalue, value))
• r.lset(name, index, value)
• r.lrem(name, value, num)
• lpop(name)
• lindex(name, index)
• lrange(name, start, end)
• ltrim(name, start, end)
• rpoplpush(src, dst)
• blpop(keys, timeout)
• brpoplpush(src, dst, timeout=0)

五、set

• sadd(name,values)
• scard(name)
• sdiff(keys, *args)
• sdiffstore(dest, keys, *args)
• sinter(keys, *args)
• sinterstore(dest, keys, *args)
• sismember(name, value)
• smembers(name)
• smove(src, dst, value)
• spop(name)
• srandmember(name, numbers)
• srem(name, values)
• sunion(keys, *args)
• sunionstore(dest,keys, *args)
• sscan(name, cursor=0, match=None, count=None)
• sscan_iter(name, match=None, count=None)
