amazon-web-services - AWS CLI 命令/JMESPATH 查询问题

Question

你们中的任何人都可以帮我找出 CLI 命令 /JMESPATH 查询中的问题 - “什么不起作用？

下面给出的 PS JSON 输出是有效的，您可以使用输出在 JMESPATH.org 上测试其中的 JMESPATH 查询部分

什么有效？

1) aws ec2 describe-security-groups --query SecurityGroups[?GroupId=='sg-0a26abc0a00000000'].IpPermissions[]
2) aws ec2 describe-security-groups --query SecurityGroups[?GroupId=='sg-0a26abc0a00000000'].IpPermissions[].FromPort
3)aws ec2 describe-security-groups --query SecurityGroups[?GroupId=='sg-0a26abc0a00000000'].IpPermissions[].IpProtocol

什么不工作？

1) aws ec2 describe-security-groups --query SecurityGroups[?GroupId=='sg-0a26abc0a00000000'].IpPermissions[?IpProtocol=='tcp'].IpProtocol
2)aws ec2 describe-security-groups --query SecurityGroups[?GroupId=='sg-0a26abc0a00000000'].IpPermissions[?FromPort=='22'].FromPort

预期/实际结果

aws ec2 describe-security-groups --query SecurityGroups[?GroupId=='sg-0a26abc0a00000000'].IpPermissions[?IpProtocol=='tcp'].IpProtocol

结果

预期 - tcp，实际 - 不返回结果

aws ec2 describe-security-groups --query SecurityGroups[?GroupId=='sg-0a26abc0a00000000'].IpPermissions[?FromPort=='22'].FromPort

结果

预期 - 22，实际 - 不返回结果

Answer 1

SecurityGroups[?GroupId=='sg-0a26abc0a00000000'].IpPermissions[] | [?IpProtocol=='tcp'].IpProtocol | [0]

SecurityGroups[?GroupId=='sg-0a26abc0a00000000'].IpPermissions[] | [?FromPort==`22`].FromPort | [0]

或者，为 bash 引用/调整：

'SecurityGroups[?GroupId==`"sg-0a26abc0a00000000"`].IpPermissions[] | [?IpProtocol==`"tcp"`].IpProtocol | [0]'

'SecurityGroups[?GroupId==`"sg-0a26abc0a00000000`"].IpPermissions[] | [?FromPort==`22`].FromPort | [0]'

您会注意到[]IpPermissions 末尾的 ，它使列表变平。如果您不这样做（或不这样做SecurityGroups[?GroupId=='sg-0a26abc0a00000000'][]），则过滤器将应用于列表的顶级，其中不存在 IpPermissions。

我不清楚为什么这是真的。这似乎是错误的，因为没有较早的过滤器，以后的过滤器将应用于子列表。
