这就是我的JSON对象数组：
[
{
"Description": "Description 1",
"OutputKey": "OutputKey 1",
"OutputValue": "OutputValue 1"
},
{
"Description": "Description 2",
"OutputKey": "OutputKey 2",
"OutputValue": "OutputValue 2"
},
{
"Description": "Description 3",
"OutputKey": "OutputKey 3",
"OutputValue": "OutputValue 3"
},
{
"Description": "Description 4",
"OutputKey": "OutputKey 4",
"OutputValue": "OutputValue 4"
},
{
"Description": "Description 5",
"OutputKey": "OutputKey 5",
"OutputValue": "OutputValue 5"
},
{
"Description": "Description 6",
"OutputKey": "OutputKey 6",
"OutputValue": "OutputValue 6"
}
]
我如何使用jq对此进行迭代，以便可以在其他命令中使用OutputKey和OutputValue的值？
假设您的内容来自in.json：
#!/usr/bin/env bash
case $BASH_VERSION in (""|[123].*) echo "Bash 4.0 or newer required" >&2; exit 1;; esac
declare -A values=( ) descriptions=( )
while IFS= read -r description &&
IFS= read -r key &&
IFS= read -r value; do
values[$key]=$value
descriptions[$key]=$description
echo "Read key $key, with value $value and description $description" >&2
done < <(jq -r '.[] | (.Description, .OutputKey, .OutputValue)' <in.json)
根据您的输入，这将向stderr发出以下消息：
Read key OutputKey 1, with value OutputValue 1 and description Description 1
Read key OutputKey 2, with value OutputValue 2 and description Description 2
Read key OutputKey 3, with value OutputValue 3 and description Description 3
Read key OutputKey 4, with value OutputValue 4 and description Description 4
Read key OutputKey 5, with value OutputValue 5 and description Description 5
Read key OutputKey 6, with value OutputValue 6 and description Description 6
此外，运行此代码后，您可以然后执行：
key_to_look_up="OutputKey 1"
echo "${values[$key_to_look_up]}"
echo "${descriptions[$key_to_look_up]}"
...并作为输出：
OutputValue 1
Description 1
