 參照： https://www.runoob.com/redis/scripting-eval.html

 參照文檔可知道： keys全部寫在前面，中間2是key的數(shù)量，val值后面排著寫

const luaScript = `return redis.call('MSET', KEYS[1],ARGV[1], KEYS[2],ARGV[2])`;

redis.defineCommand("evalTest", {
    numberOfKeys: 2,
    lua: luaScript,
})
async function eval() {
    await redis.evalTest('testKey1', 'testKey2', 'val1', 'val2');
    const result = await redis.get('testKey1');
    const result2 = await redis.get('testKey2');
    console.log(result, result2); // val2
}
eval();
