尝试运行包含的 CloudWatch Insights 查询reqHeaders.x-forwarded-for，例如

fields @timestamp, status, err, method, url, req_id, reqHeaders.x-forwarded-for
| filter status >= 400
| sort @timestamp desc
| limit 10

但是这个字段总是空的，尽管它被正确地解析了@message。我怀疑这是因为子字段名称中的连字符。有人知道如何重新格式化查询以显示它吗？

编辑：这是一个日志消息示例（纯 JSON，我只是对其进行了格式化）

把它放在“`”之间

fields @timestamp, status, err, method, url, req_id, `x-forwarded-for`

自己找到的

fields @timestamp, status, err, method, url, req_id
| parse @message '"x-forwarded-for":"*"' as ip
| filter status >= 400
| sort @timestamp desc
| limit 10
