对 AVIF 图像禁用压缩

以下示例规则将根据请求中指定的内容类型或文件扩展名，对 AVIF 图像禁用压缩。

当传入请求匹配时

自定义筛选表达式：
- Media Type equals image/avif OR
- File extension equals avif

然后

Compression options > Disable compression

以下示例使用 Update a zone ruleset 操作，将现有入口点规则集（ID 为 {ruleset_id}）在 http_response_compression 阶段的规则设置为单条压缩规则：

curl "https://api.cloudflare.com/client/v4/zones/$ZONE_ID/rulesets/$RULESET_ID" \
	--request PUT \
	--header "Authorization: Bearer $CLOUDFLARE_API_TOKEN" \
	--json '{
		"rules": [
				{
						"ref": "disable_compression_for_avif",
						"expression": "http.response.content_type.media_type eq \"image/avif\" or http.request.uri.path.extension eq \"avif\"",

	}'

使用 Terraform 时，通过 ref 字段可在更新后保持稳定的规则 ID。添加该字段可防止 Terraform 在变更时重建规则。更多信息请参阅故障排除（Terraform 文档）。
