Redis集合存储在不同服务器为什么表现不同

$redis = Redis::connection()->client();
$redis->select(7);
$models = RoomModel::where("category_id", 1)->get();
$models->map(function (RoomModel $model) use ($redis) {
$key = "room:category_id:".$model->category_id;
    $redis->sAdd($key, $model->toArray());
    $redis->expireAt($key, now()->addDays(random_int(20, 30))->timestamp);
});
$key = "room:category_id:1";
$data = $redis->sMembers($key);
$redis->close();Copy
