是否有(Unix)shell脚本将JSON格式化为可读格式?
基本上,我希望它转换以下内容:
{ "foo": "lorem", "bar": "ipsum" }
…变成这样:
{
"foo": "lorem",
"bar": "ipsum"
}

TL;DR:对于性能,请使用jj-p<my.json。
基准
我在这里采取了一些解决方案,并用下一个虚拟脚本对它们进行了基准测试:
function bench {
time (
for i in {1..1000}; do
echo '{ "foo" : { "bar": { "dolorem" : "ipsum", "quia" : { "dolor" : "sit"} } } }' \
| $@ > /dev/null
done
)
}
这是我的mac(32 GB,苹果M1 Max,YMMV)上的结果:
bench python -m json.tool
# 8.39s user 12.31s system 42% cpu 48.536 total
bench jq
# 13.12s user 1.28s system 87% cpu 16.535 total
bench bat -p -l json # NOTE: only syntax colorisation.
# 1.87s user 1.47s system 66% cpu 5.024 total
bench jj -p
# 1.94s user 2.44s system 57% cpu 7.591 total
bench xidel -s - -e '$json' --printed-json-format=pretty
# 4.32s user 1.89s system 76% cpu 8.101 total
感谢@peak和您对jj发现的回答!
或者,使用Ruby:
echo '{ "foo": "lorem", "bar": "ipsum" }' | ruby -r json -e 'jj JSON.parse gets'
如果您想在控制台可视化json日志,可以使用munia漂亮的json
npm install -g munia-pretty-json
您的json数据(app-log.json)
{"time":"2021-06-09T02:50:22Z","level":"info","message":"Log for pretty JSON","module":"init","hostip":"192.168.0.138","pid":123}
{"time":"2021-06-09T03:27:43Z","level":"warn","message":"Here is warning message","module":"send-message","hostip":"192.168.0.138","pid":123}
运行命令:
munia-pretty-json app-log.json
下面是控制台上的可读输出:
您可以使用模板格式化输出。默认模板为“{time}{level-c}{{message}”
使用模板:
munia-pretty-json -t '{module -c} - {level} - {message}' app-log.json
输出:
我是json liner的作者。这是一个命令行工具,用于将JSON转换为grep友好格式。试试看。
$ echo '{"a": 1, "b": 2}' | json-liner
/%a 1
/%b 2
$ echo '["foo", "bar", "baz"]' | json-liner
/@0 foo
/@1 bar
/@2 baz
JSONLint在GitHub上有一个开源实现,可以在命令行上使用,也可以包含在Node.js项目中。
npm install jsonlint -g
然后
jsonlint -p myfile.json
or
curl -s "http://api.twitter.com/1/users/show/user.json" | jsonlint | less
