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"
}

当前回答

我正在使用httpie

$ pip install httpie

你可以这样使用

 $ http PUT localhost:8001/api/v1/ports/my 
 HTTP/1.1 200 OK
 Connection: keep-alive
 Content-Length: 93
 Content-Type: application/json
 Date: Fri, 06 Mar 2015 02:46:41 GMT
 Server: nginx/1.4.6 (Ubuntu)
 X-Powered-By: HHVM/3.5.1

 {
     "data": [], 
     "message": "Failed to manage ports in 'my'. Request body is empty", 
     "success": false
 }

多亏了J.F.Sebastian非常有用的指导,我想出了一个稍微增强的脚本:

#!/usr/bin/python

"""
Convert JSON data to human-readable form.

Usage:
  prettyJSON.py inputFile [outputFile]
"""

import sys
import simplejson as json


def main(args):
    try:
        if args[1] == '-':
            inputFile = sys.stdin
        else:
            inputFile = open(args[1])
        input = json.load(inputFile)
        inputFile.close()
    except IndexError:
        usage()
        return False
    if len(args) < 3:
        print json.dumps(input, sort_keys = False, indent = 4)
    else:
        outputFile = open(args[2], "w")
        json.dump(input, outputFile, sort_keys = False, indent = 4)
        outputFile.close()
    return True


def usage():
    print __doc__


if __name__ == "__main__":
    sys.exit(not main(sys.argv))

使用以下命令安装yajl工具:

sudo apt-get install yajl-tools

然后

echo '{"foo": "lorem", "bar": "ipsum"}' | json_reformat

import json
import jsonschema

def _validate(data):
    schema = {"$schema": "http://json-schema.org/draft-04/schema#"}
    try:
        jsonschema.validate(data, schema,
                            format_checker=jsonschema.FormatChecker())
    except jsonschema.exceptions.ValidationError as ve:
        sys.stderr.write("Whoops, the data you provided does not seem to be " \
        "valid JSON.\n{}".format(ve))

def pprint(data, python_obj=False, **kwargs):
    _validate(data)
    kwargs["indent"] = kwargs.get("indent", 4)
    pretty_data = json.dumps(data, **kwargs)
    if python_obj:
        print(pretty_data)
    else:
       repls = (("u'",'"'),
                ("'",'"'),
                ("None",'null'),
                ("True",'true'),
                ("False",'false'))
    print(reduce(lambda a, kv: a.replace(*kv), repls, pretty_data))

您可以简单地使用jq或json_pp等标准工具。

echo'{“foo”:“lorem”,“bar”:“ipsum”}'| json_pp

or

echo“{”foo“:”lorem“,”bar“:”ipsum“}”| jq

将像下面这样美化输出(jq甚至更丰富多彩):

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

jq的巨大优势在于,如果您想解析和处理json,它可以做更多的工作。

使用Node.js的单线解决方案如下所示:

$ node -e "console.log( JSON.stringify( JSON.parse(require('fs').readFileSync(0) ), 0, 1 ))"

例如:

$ cat test.json | node -e "console.log( JSON.stringify( JSON.parse(require('fs').readFileSync(0) ), 0, 1 ))"
