the same issue, I dont know how to use that method. @AlexProfi have you get the solution?

You're generally better off using the role param when calling connect_via_sentinel.
The get_master and get_slaves methods are used internally by connect_via_sentinel.
https://github.com/ledgetech/lua-resty-redis-connector/blob/master/lib/resty/redis/connector.lua#L237

If you do want to use them directly the first argument is an instance of resty-redis already connected to a sentinel and the second arg is the master name configuration in sentinel.
e.g. something like this (untested code)

local sentinel = require("resty.redis").new()
sentinel:connect("my_sentinel.host", 6380)

local master = require("resty.redis.sentinel").get_master(sentinel, "my_master_name")

@AlexProfi can I use the method in stream that load balance the redis, when the redis master down and pick a new one immediately.

I don't really understand.

If you use the sentinel syntax (https://github.com/ledgetech/lua-resty-redis-connector#connections-via-redis-sentinel) then it will always ask sentinel for the current master and then make a connection to that host.
