Attempts to connect to the remote host and port that the redis server
is listening to or a local unix domain socket file listened by the
redis server.
Before actually resolving the host name and connecting to the remote
backend, this method will always look up the connection pool for matched
idle connections created by previous calls of this method.
An optional Lua table can be specified as the last argument to this method to specify various connect options:

测试发现第二次请求后redis_conn就断开了，请教如何保持redis的一次连接多次使用
