不可能创建一个空数组并向其中添加json对象吗

Question

for region in $(jq '.data | keys | .[]' <<< "$data"); do
value=$(jq -r ".data[$region]" <<< "$data");
deliveryRegionId=$(jq -r '.deliveryRegionId' <<< "$value");
json_template='{}';
json_data=$(jq --argjson deliveryRegionId "$deliveryRegionId" --arg deliverableDistance 5000 '.deliveryRegionId=$deliveryRegionId | .deliverableDistance=5000' <<<"$json_template"); echo $json_data;
jq '.requestArray += "$json_data" // not work
done;
echo $requestArray

我想将json_data添加到requestArray，但似乎不起作用。如何将json_data添加到requestArray？

Answer 1

看起来这完全可以在jq中完成。

尝试直接更改data字段：

jq --argjson deliverableDistance 5000 '
.data[] += {$deliverableDistance}
' <<< "$data"

{
"data": [
{
"deliveryRegionId": 2,
"deliverableDistance": 5000
},
{
"deliveryRegionId": 3,
"deliverableDistance": 5000
}
]
}

或者，如果您想将结果对象的字段重命名为requestArray:

jq --argjson deliverableDistance 5000 '
{requestArray: (.data | map(. += {$deliverableDistance}))}
' <<< "$data"

{
"requestArray": [
{
"deliveryRegionId": 2,
"deliverableDistance": 5000
},
{
"deliveryRegionId": 3,
"deliverableDistance": 5000
}
]
}
