AWS WAF自定义JSON规则配置报错：字段需唯一值求助

报错原因 #

你配置的RuleActionOverrides里同时用了Action和OverrideAction两个字段，这俩是互斥的——AWS WAF要求每个规则覆盖只能用其中一个，不能同时设置，这就触发了"字段需要恰好一个值，但你用了多个"的报错。

修复方案 #

根据你的需求二选一修改：

情况1：不需要Count动作的额外配置 #

直接保留Action字段，删掉OverrideAction：

{
  "Name": "AWSBotControl-SignalOverride",
  "Priority": 5,
  "Statement": {
    "ManagedRuleGroupStatement": {
      "VendorName": "AWS",
      "Name": "AWSManagedRulesBotControlRuleSet",
      "RuleActionOverrides": [
        {
          "Action": "Count",
          "Name": "SignalNonBrowserUserAgent"
        }
      ]
    }
  },
  "VisibilityConfig": {
    "SampledRequestsEnabled": true,
    "CloudWatchMetricsEnabled": true,
    "MetricName": "AWSBotControl-SignalOverride"
  }
}

情况2：需要Count动作的特定配置（比如自定义采样） #

保留OverrideAction字段，删掉Action：

{
  "Name": "AWSBotControl-SignalOverride",
  "Priority": 5,
  "Statement": {
    "ManagedRuleGroupStatement": {
      "VendorName": "AWS",
      "Name": "AWSManagedRulesBotControlRuleSet",
      "RuleActionOverrides": [
        {
          "OverrideAction": { "Count": {} },
          "Name": "SignalNonBrowserUserAgent"
        }
      ]
    }
  },
  "VisibilityConfig": {
    "SampledRequestsEnabled": true,
    "CloudWatchMetricsEnabled": true,
    "MetricName": "AWSBotControl-SignalOverride"
  }
}
