Redis monitor 命令每秒显示相同的请求

Question

我刚刚设置了一个带有 Express 服务器的 Redis 客户端，以便我可以将用户会话数据保存在 Redis 存储中。出于兴趣，我正在使用 monitor 命令监视 cli 上的请求，以查看通过 Express 发出的请求。当用户登录时，我在 req.session 对象上设置了一个 userId 键，并且请求显示在 cli 上：

"set" "sess:2w8OkICwucsO9-18z_ghxA1FLH9GcWpx" "{\"cookie\":{\"originalMaxAge\":3600000,\"expires\":\"2020-10-09T12:09:37.604Z\",\"secure\":false,\"httpOnly\":true,\"path\":\"/\"}}" "EX" "3600"

但是在存储会话信息后，get 和 expire 命令显示在 cli 上：

1602241780.017805 [0 127.0.0.1:61201] "get" "sess:2w8OkICwucsO9-18z_ghxA1FLH9GcWpx"
1602241780.026601 [0 127.0.0.1:61201] "expire" "sess:2w8OkICwucsO9-18z_ghxA1FLH9GcWpx" "3600"
1602241783.014473 [0 127.0.0.1:61201] "get" "sess:2w8OkICwucsO9-18z_ghxA1FLH9GcWpx"
1602241783.020260 [0 127.0.0.1:61201] "expire" "sess:2w8OkICwucsO9-18z_ghxA1FLH9GcWpx" "3600"
1602241786.018502 [0 127.0.0.1:61201] "get" "sess:2w8OkICwucsO9-18z_ghxA1FLH9GcWpx"
1602241786.024512 [0 127.0.0.1:61201] "expire" "sess:2w8OkICwucsO9-18z_ghxA1FLH9GcWpx" "3600"
1602241789.018028 [0 127.0.0.1:61201] "get" "sess:2w8OkICwucsO9-18z_ghxA1FLH9GcWpx"
1602241789.023479 [0 127.0.0.1:61201] "expire" "sess:2w8OkICwucsO9-18z_ghxA1FLH9GcWpx" "3600"

每秒钟都这样..

我很确定我不会经常通过 Express 调用任何函数，那么为什么 monitor 命令会显示这些请求？

Answer 1

问题出在每 2 秒执行一次内省查询的 GraphQL Playground。我在设置选项卡中禁用了该设置，它起作用了！
