将 JSON 数组组织到菜单中

Question

我从 API 获得了这些数据：

[{"name":"***.com","id":"***-0a5864441f49","type":"NATIVE"},{"name":"***.de","id":"***-0a5864441f49","type":"NATIVE"},{"name":"***.com","id":"***-0a5864440f67","type":"NATIVE"},{"name":"***.de","id":"***-0a5864441314","type":"NATIVE"},{"name":"***.com","id":"***-0a586444968b","type":"NATIVE"},{"name":"***.de","id":"***-0a5864441314","type":"NATIVE"},{"name":"***.de","id":"***-0a5864441f49","type":"NATIVE"},{"name":"***.de","id":"***-0a5864441f49","type":"NATIVE"},{"name":"***.de","id":"***-0a58644406ac","type":"NATIVE"},{"name":"***.de","id":"***-0a58644435f4","type":"NATIVE"}]

我想从中创建一个菜单，如下所示：

Choose one:
1. ***.com ***-0a5864441f49
2. ***.de ***-0a5864441f49
and so on...

然后我想进一步使用输入。在 bash 中执行此操作最有效的方法是什么？

我正在考虑一个数组，但我认为 IFS 不喜欢我使用

},{

作为分隔符，对吗？

我尝试使用 IFS 但没有成功。

您可以使用 jq 将输入转换为如下所示（请参阅playground）：

$ jq -r 'map("\(.name) \(.id)")[]' infile.json
***.com ***-0a5864441f49
***.de ***-0a5864441f49
***.com ***-0a5864440f67
***.de ***-0a5864441314
-->8--

基于此，您可以将此输出读入数组，然后使用

select

内置函数来呈现菜单：

readarray -t opts < <(jq -r 'map("\(.name) \(.id)")[]' infile.json)

PS3='Choose one: '
select opt in "${opts[@]}"; do
    echo "Do something with $opt"
    break
done

导致类似的提示

1) ***.com ***-0a5864441f49    6) ***.de ***-0a5864441314
2) ***.de ***-0a5864441f49     7) ***.de ***-0a5864441f49
3) ***.com ***-0a5864440f67    8) ***.de ***-0a5864441f49
4) ***.de ***-0a5864441314     9) ***.de ***-0a58644406ac
5) ***.com ***-0a586444968b   10) ***.de ***-0a58644435f4
