python中如何查找redis里的数据

python中查找Redis数据的方法：1、打开终端；2、输入命令创建命令脚本；3、给脚本添加查找redis数据的代码；4、输入命令执行脚本连接redis即可。

具体操作步骤如下：

打开终端命令行模式。

输入以下命令创建命令脚本。

cat yisu.py #创建脚本

在脚本中添加以下连接redis代码。

import redis
#from rediscluster import StrictRedisCluster
from click._compat import raw_input
from rediscluster import RedisCluster as StrictRedisCluster
def redis_cmd(redis_nodes,isClusterMode=True):
if isinstance(redis_nodes,list):
pass
elif isinstance(redis_nodes,str):
tmp_nodes = []
tmp_tuple = redis_nodes.split(",")
for tt in tmp_tuple:
tt_node = {"host":tt.split(":")[0],"port":tt.split(":")[1]}
tmp_nodes.append(tt_node)
redis_nodes = tmp_nodes
if isClusterMode:
rc = StrictRedisCluster(startup_nodes=redis_nodes, decode_responses=True)
else:
rc = redis.Redis(host=redis_nodes[0]["host"],port=redis_nodes[0]["port"],decode_responses=True)
while True:
s = raw_input("input cmd: >>> ")
if s == "quit" or s == "exit":
print("query end.")
break
cmd = s.split(" ")[0]
key = s.split(" ")[1:]
if cmd.lower() not in ["", "ltrim","ttl", "get", "key", "keys", "set", "lrange", "hget", "smembers", "zrange", "type", "pfcount", "zrange", "hgetall","del", "sismember","sadd","hset","llen","srem","scard","info","cluster info","info Keyspace","hlen","hdel"]:
print ("wrong type of command, please retry...")
elif cmd == "ttl":
print(rc.ttl(*key))
elif cmd == "ltrim":
print(rc.ltrim(*key))
elif cmd == "get":
print(rc.get(*key))
elif cmd == "key":
print(rc.key(*key))
elif cmd == "keys":
print(rc.keys(*key))
elif cmd == "set":
print(rc.set(*key))
elif cmd == "lrange":
print(rc.lrange(*key))
elif cmd == "hget":
print(rc.hget(*key))
elif cmd == "smembers":
print(rc.smembers(*key))
elif cmd == "srem":
print(rc.srem(*key))
elif cmd == "zrange":
print(rc.zrange(*key))
elif cmd == "type":
print(rc.type(*key))
elif cmd == "pfcount":
print(rc.pfcount(*key))
elif cmd == "zrange":
print(rc.zrange(*key))
elif cmd == "hgetall":
print(rc.hgetall(*key))
elif cmd == "del":
print(rc.delete(*key))
elif cmd == "sismember":
print(rc.sismember(*key))
elif cmd == "sadd":
print(rc.sadd(*key))
elif cmd == "scard":
print(rc.scard(*key))
elif cmd == "hset":
print(rc.hset(*key))
elif cmd == "llen":
print(rc.llen(*key))
elif cmd == "hlen":
print(rc.hlen(*key))
elif cmd == "hdel":
print(rc.hdel(*key))
elif cmd == "info":
print(rc.info(*key))
elif cmd == "cluster info":
print(rc.info("cluster"))
elif cmd == "info Keyspace":
print(rc.info("Keyspace"))
def usage():
pass
if __name__=="__main__":
redis_nodes = "172.17.9.106:16388,172.17.9.108:16388"
isRedisCluster = False

输入以下命令执行脚本连接redis即可。

python3 yisu.py
