表达式验证

Cloudflare 过滤器 API 支持用于验证表达式的端点。

示例

通过查询字符串验证表达式

Requestbash

curl "https://api.cloudflare.com/client/v4/filters/validate-expr?expression=ip.src==34" \
--header "X-Auth-Email: <EMAIL>" \
--header "X-Auth-Key: <API_KEY>"

Responsejson

{
  "result": null,
  "success": false,
  "errors": [
    {
      "message": "Filter parsing error:\n`ip.src==34`\n          ^^ couldn't parse address in network: invalid IP address syntax\n"
    }
  ],
  "messages": null
}

请注意响应中的验证错误。在此示例中，错误是由于无效的 IP 地址格式引起的：

Filter parsing error:
`ip.src==34`
          ^^ couldn't parse address in network: invalid IP address syntax

通过 JSON 对象验证表达式

Requestbash

curl "https://api.cloudflare.com/client/v4/filters/validate-expr" \
--header "X-Auth-Email: <EMAIL>" \
--header "X-Auth-Key: <API_KEY>" \
--header "Content-Type: application/json" \
--data '{
  "expression": "ip.src in {2400:cb00::/32 2405:8100::/2000 2c0f:f248::/32 2a06:98c0::/29}"
}'

Responsejson

{
  "result": null,
  "success": false,
  "errors": [
    {
      "message": "Filter parsing error:\n`ip.src in {2400:cb00::/32 2405:8100::/2000 2c0f:f248::/32 2a06:98c0::/29}`\n                                        ^^^^ number too large to fit in target type while parsing with radix 10\n"
    }
  ],
  "messages": null
}

请注意响应中的验证错误。在此示例中，子网掩码的值 /2000 不是有效的 IPv6 CIDR 掩码：

Filter parsing error:
`ip.src in {2400:cb00::/32 2405:8100::/2000 2c0f:f248::/32 2a06:98c0::/29}`
                                        ^^^^ number too large to fit in target type while parsing with radix 10
