在我的 Unix shell 脚本中，当我执行 curl 命令时，结果将显示如下，我正在重定向到文件:

{"type":"Show","id":"123","title":"name","description":"Funny","channelTitle":"ifood.tv","lastUpdateTimestamp":"2014-04-20T20:34:59","numOfVideos":"15"}

但是，我希望此输出以可读的 JSON 格式放入文件中，如下所示:

{"type":"Show",
"id":"123",
"title":"name",
"description":"Funny",
"channelTitle":"ifood.tv",
"lastUpdateTimestamp":"2014-04-20T20:34:59",
"numOfVideos":"15"}

如何以这种方式格式化输出？

最佳答案

一些解决方案可供选择:

json_pp: command utility available in Linux systems for JSON decoding/encoding

echo '{"type":"Bar","id":"1","title":"Foo"}' | json_pp -json_opt pretty,canonical
{
   "id" : "1",
   "title" : "Foo",
   "type" : "Bar"
}

您可能希望保持 -json_opt 漂亮、规范 参数以实现可预测的排序。

jq: lightweight and flexible command-line JSON processor. It is written in portable C, and it has zero runtime dependencies.

echo '{"type":"Bar","id":"1","title":"Foo"}' | jq '.'
{
  "type": "Bar",
  "id": "1",
  "title": "Foo"
}

最简单的jq程序是表达式.，它接受输入并将其原样作为输出产生。

对于附加 jq 选项检查 the manual

与 python :

echo '{"type":"Bar","id":"1","title":"Foo"}' | python -m json.tool
{
    "id": "1",
    "title": "Foo",
    "type": "Bar"
}

与 nodejs和 bash :

echo '{"type":"Bar","id":"1","title":"Foo"}' | node -e "console.log( JSON.stringify( JSON.parse(require('fs').readFileSync(0) ), 0, 1 ))"
{
 "type": "Bar",
 "id": "1",
 "title": "Foo"
}
