resty redis add_commands

gg.lafon

Hello,

I call the
redis.add_commands("hscan")
in resty_redis module in order to use the HSCAN command but when I use it with

local res, err = red:hscan("myHash", "0", "*", "200")
there is the following error:
ERR unknown command 'hscan'

I think you wonder the cached ocsp status response expire, so if you want to use the ocsp stapling, you should use validate_ocsp_response function to check &...

It's the same with the folowwing parameters:

local res, err = red:hscan("myHash", "0", "MATCH *", "COUNT 200")

local res, err = red:hscan("myHash", "0")

Any advice would be much appreciated.

HSCAN is new in Redis 2.8. Perhaps you're running an older version of Redis? Works for me on 2.8.1.

You are right, my bad!

Thank you.

Are you able to pass some parameters like MATCH and COUNT?

On my side it does not work.

Yes. Remember the lua-resty-redis module simply passes the the commands over the wire, so if something doesn't work for you first experiment with redis-cli and review the documentation. If your command works on the command line, it should work with the Lua module.

I just tried this on redis-cli (on a Hash where one element is a Last-Modified HTTP header)

HSCAN mykey 0 MATCH Last*

1) "0"

2) 1) "Last-Modified"

2) "Mon, 10 Dec 2012 10:09:11 GMT"

Each of the elements in my command above need to be placed as individual arguments in the lua-resty-redis function call, as in:

local ok, err = redis:hscan("mykey", 0, "match", "Last*")

You seem to be passing the * to your match inside the same parameter?
