How to pass variable to lua script from java? ( io.lettuce.core )

dk40149 :

I have a lua script like this that does an hgetall command on a remote redis cluster:

String shaFindAccount = syncCommands.scriptLoad("local hgetAllKeys = function(key) \n" +
                                                "local acc = redis.call('HGETALL', key)\n" +
                                                "return acc\n" +
                                                "end\n");

I want to pass a variable to the hgetall call. This is what my eval statement, calling the above script, looks like:

list = syncCommands.evalsha(shaFindAccount, ScriptOutputType.MULTI, key);

Where key is a unique identifier (primary key) of acc. Right now this function returns an empty list.

How do I pass a java variable into the above lua script with io.lettuce.core? (There are no connection issues, i can use a similar query with a hardcoded key value and it works)

You can find some example in this unit test. It seems you should call it in this way:

list = syncCommands.evalsha(digest, MULTI, new String[0], key));

and you should refer the argument as ARGV[1].
