jq迭代和条件

标签: json linux bash jq

我有一些需要使用jq解析的json。我正在尝试提取 如果任何SecurityGroups> IpPermissions> IpRanges> CidrIp匹配某个IP,则SecurityGroups> GroupId。

例如,搜索11.11.11.11应该返回sg-3jf32kj3j。多个安全组可能包含该IP。我需要返回所有的GroupId。

单独使用jq还是有可能吗?还是需要bash?

与仅使用Python之类的方法相比,我发现jq语法令人困惑。

答案 0 :(得分:1)

以下过滤器满足规定的要求:

.SecurityGroups[]
| select( any(.IpPermissions[].IpRanges[];
              .CidrIp | startswith("11.11.11.11/") ) )
| .GroupId

尤其是在您输入时,它会产生所需的值:

"sg-3jf32kj3j"

您可能想考虑使用以下更复杂的模式匹配:

test("^11.11.11.11($|/)")

如果要删除引号,请考虑使用jq的-r命令行选项。

使用..

这是另一种解决方案,但请注意,它具有完全不同的语义:

..
| select( .. |  test("^11.11.11.11($|/)")? )
| .GroupId? // empty

我可以为您提供替代解决方案吗?这是我最近开发的unix实用程序jtc的样子:

bash $ cat file.json | jtc -w'<^11.11.11.11\/>R: [-5] [GroupId]' 
"sg-3jf32kj3j"
bash $

它还将显示显示此IP地址的所有组。如果愿意,可以在github.com上找到该实用程序,或者使用jtcjson关键字在Google上对其进行搜索
