如何在shell脚本中漂亮地打印JSON? [英] How can I pretty-print JSON in a shell script?

问题描述

是否存在一个(Unix)Shell脚本来以人类可读的格式格式化JSON?

Is there a (Unix) shell script to format JSON in human-readable form?

基本上，我希望它改变以下内容:

Basically, I want it to transform the following:

{ "foo": "lorem", "bar": "ipsum" }

...变成这样:

{
    "foo": "lorem",
    "bar": "ipsum"
}

推荐答案

使用Python 2.6+，您可以执行以下操作:

With Python 2.6+ you can just do:

echo '{"foo": "lorem", "bar": "ipsum"}' | python -m json.tool

或者，如果JSON在文件中，则可以执行以下操作:

or, if the JSON is in a file, you can do:

python -m json.tool my_json.json

如果JSON来自互联网资源(例如API)，则可以使用

if the JSON is from an internet source such as an API, you can use

curl http://my_url/ | python -m json.tool

为方便起见，在所有这些情况下，您都可以创建别名:

For convenience in all of these cases you can make an alias:

alias prettyjson='python -m json.tool'

---

通过输入更多内容来更加方便:

For even more convenience with a bit more typing to get it ready:

prettyjson_s() {
    echo "$1" | python -m json.tool
}

prettyjson_f() {
    python -m json.tool "$1"
}

prettyjson_w() {
    curl "$1" | python -m json.tool
}

以上所有情况.您可以将其放在.bashrc中，并且每次在Shell中都可用.像prettyjson_s '{"foo": "lorem", "bar": "ipsum"}'一样调用它.

for all the above cases. You can put this in .bashrc and it will be available every time in shell. Invoke it like prettyjson_s '{"foo": "lorem", "bar": "ipsum"}'.
