我正在尝试从中获取以下格式：

2.14.11.41:80
2.14.11.41:8001
2.22.22.102:80
2.22.22.102:8001
2.22.22.102:8089
4.54.84.19:443

即select IP 和端口，如果 service_name 等于 HTTP。我知道如何获取 IP jq -r '.[].result.hits[] | select(.services[].service_name == "HTTP") | .ip' 以及如何仅获取端口 jq -r '.[].result.hits[].services[] | select(.service_name == "HTTP") | .port'，但我不明白如何在一个命令中正确组合它。有人可以指出正确的方向吗？

Answer 1

将 IP 保存在变量中，使您的选择更深一层。然后，如果匹配则打印出来：

jq -r '.[].result.hits[] | .ip as $ip | .services[] | select(.service_name == "HTTP") | "\($ip):\(.port)"'

2.14.11.41:80
2.14.11.41:8001
2.22.22.102:80
2.22.22.102:8001
2.22.22.102:8089
4.54.84.19:443
