通过redis-cli+lua脚本查询redis数据

1)powershell

PS C:\Users\LX-SLM\Desktop> redis-cli -h 127.0.0.1 -p 36379 -a xxx --eval r.lua

2)lua

local res={}
local cursor='0'
repeat
    local scanRet=redis.call('SCAN',cursor,'MATCH','Player_*','COUNT',1000,'TYPE','hash')
    cursor=scanRet[1]
    local keys=scanRet[2]
    for _,k in ipairs(keys)do
        local v=redis.call('HGET',k,'friendSize')
        local num=tonumber(v or 0)
        if num>0 then
            -- 同时存入key和对应数值
            table.insert(res,{k,num})
        end
    end
until cursor=='0'
return res
