windows redis+lua的調試

1.編寫lua腳本my.lua

local key = KEYS[1] --限流KEY(一秒一個)
local limit = tonumber(ARGV[1])        --限流大小
local current = tonumber(redis.call('get', key) or "0")
if current + 1 > limit then --若是超出限流大小
    return 0
else  --請求數+1,並設置2秒過時
    redis.call("INCRBY", key,"1")
    redis.call("expire", key,"2")
    return 1
end

  

2.把寫好的lua腳本my.lua放到windows redis目錄下面就是和redis-cli.exe同級目錄

D:\Redis-x64-3.2.100
   my.lua

  

3.打開windows cmd命令窗口執行命令

D:\Redis-x64-3.2.100>redis-cli.exe --eval my5.lua 1 ip:1213 , 5

  

上面命令解釋來源:https://www.redisgreen.net/blog/intro-to-lua-for-redis-programmers/

redis-cli.exe --eval my5.lua 1 ip:1213 , 5

  

上面命令中的1表示有幾個key這裏只有一個key 因此lua代碼中只能用KEY[1]獲取
KEY[1]=ip:1213

逗號,表示分割KEY和ARGV

再看一個例子:

local link_id = redis.call("INCR", KEYS[1])
redis.call("HSET", KEYS[2], link_id, ARGV[1])
return link_id

redis-cli --eval incrset.lua links:counter links:urls , http://malcolmgladwellbookgenerator.com/

  

終於在國外一個大神寫的call函數解決我困惑一天的問題


local redis = require 'redis'

-- If you have some different host/port change it here
local host = "127.0.0.1"
local port = 6379

client = redis.connect(host, port)

-- Workaround for absence of redis.call or atelast I did not find one
-- And did not want to digg in redis source code to see how does he get redis.call
redis.call = function(cmd, ...) 
    return assert(loadstring('return client:'.. string.lower(cmd) ..'(...)'))(...)
end


local r = redis.call('get', 'foo')
print(r)
