只有在字符串数组中找到值V时，jq才能获得字段的所有值

Question

我需要获取所有Distinct"节点"；仅当在数据对象的数组中；ServiceTags"；具有字符串元素"；"管弦乐队"；。

例如，对于json:

[
{
"Node": "abc",
"ServiceTags": [],
"Type": "",
"Definition": {
"Interval": "0s",
"Timeout": "0s"
},
"CreateIndex": 11241543,
"ModifyIndex": 11241543
},
{
"Node": "xyz",
"ServiceTags": [
"rules",
"rhdm_es",
"rhdm",
"orchestrator"
],
"Type": "http",
"Definition": {
"Interval": "0s",
"Timeout": "0s"
},
"CreateIndex": 12907642,
"ModifyIndex": 12907659
},
{
"Node": "teb",
"ServiceTags": [
"rules",
"orchestrator"
],
"Type": "http",
"Definition": {
"Interval": "0s",
"Timeout": "0s"
},
"CreateIndex": 12907642,
"ModifyIndex": 12907659
},
{
"Node": "iry",
"ServiceTags": [
"rules"
],
"Type": "http",
"Definition": {
"Interval": "0s",
"Timeout": "0s"
},
"CreateIndex": 12907642,
"ModifyIndex": 12907659
}
]

预期的结果将是一个包含值"0"的数组；xyz"；以及"；teb"；因为存在一个"；管弦乐队；作为"；ServiceTags"；所有物

如果有任何帮助，我将不胜感激，我目前正在一个只打印所有ServiceTags:的基本shell脚本中进行此操作

# Get consul data in json format
consulResult=$(cat -)
# Validate if the json is not null or empty
if [ -z "$consulResult" ];
then
echo "NULL OR EMPTY";
else
echo "Not NULL";
echo $consulResult | jq '.[].ServiceTags'
fi

Answer 1

map(select(.ServiceTags | index("orchestrator")).Node)

将根据ServiceTags数组中是否存在orchestrator进行筛选，然后为这些对象输出.Node

输出：

[
"xyz",
"teb"
]
