jq:在JSON中解析和显示多个值

Question

我有这个test.json文件

{
  "list": [
    {
      "expand": "xx",
      "id": "xxxxx",
      "self": "https",
      "key": "test-11",
      "fields": {
        "field_1": "1234"
      }
    },
    {
      "expand": "xx",
      "id": "xxxxx",
      "self": "https",
      "key": "test-10",
      "fields": {
        "field_1": "1235",
        "field_2": null
      }
    }
  ]
}

我试图使用IFS while循环读取这些值：

cat test.json| jq -r '[.list[]| ([.key]|tostring) + "," + "\(.fields| .field_1)"]|@tsv' \
| while IFS="," read -r key field_1; do
echo "$key $field_1"
curl -s https ://thisistest.com/api/$key/$field_1
done;
echo output displays only: test-11

我希望获得key和field_1的值，以便在curl请求中使用它们。

注释中@Kev的jq命令将提取您想要的值，每一行每对，如下所示：

> jq -r '.list[]|[.key,.fields.field_1]|@tsv' test.json
test-11 1234
test-10 1235

下面是如何修改脚本，使每个值对都能获得curl请求。

#!/bin/bash
while read -r key field_1; do
    echo curl -s https://thisistest.com/api/$key/$field_1
done < <( jq -r '.list[]|[.key,.fields.field_1]|@tsv' test.json )

如果您对测试满意，请删除echo。
