使用jq使用regex搜索值

Question

我有这个json对象，我正试图找到一种方法，在jq中使用regex来搜索issuer_dn中超过8个字符的值。像[A-Z]{8}这样的正则表达式应该可以工作，但我无法获得结果。我仍在学习jq，如果有任何其他工具可以使用，请分享。

Answer 1

我将使用以下内容：

.data.tls.result.handshake_log.server_certificates.certificate.parsed.issuer_dn 
| select(length > 8)

你可以在这里试试。

Answer 2

您可以使用：

test("[A-Z]{8}")
