AWS EventBridge规则模式“任何-但是”带有“前缀”

Question

我正在尝试设置一个AWS EventBridge规则，它将过滤所有Okta用户事件，其中rawUserAgent作为“任意-但是”带有“前缀”的libwww-perl。我的问题是，是否有一种方法可以在事件中的同一个字段上链接AWS规则语法？我试过这样的方法，但没成功-

{
  "detail": {
    "eventType": [{
      "prefix": "user.session.start"
    }],
    "outcome": {
      "result": [{
        "prefix": "FAILURE"
      }]
    },
    "client": {
      "userAgent": {
        "rawUserAgent": [{
          "anything-but": [{"prefix": "libwww-perl"}]
        }]
      }
    }
  }
}

对于我如何做到这一点，有什么建议吗？

下面是一个示例事件：

{
    "version": "0",
    "id": "123",
    "detail-type": "SystemLog",
    "source": "okta",

您可以使用以下模式：

{
  "detail": {
    "eventType": [{
      "prefix": "user.session.start"
    }],
    "client": {
      "userAgent": {
        "rawUserAgent": [{
          "anything-but": {
            "prefix": "libwww-perl"
          }
        }]
      }
    },
    "outcome": {
      "result": [{
        "prefix": "FAILURE"
      }]
    }
  }
}
