Comment embellir JSON en Python?
Quelqu'un peut-il suggérer comment je peux embellir JSON dans Python ou par la ligne de commande?
Le seul logiciel d’embellissement JSON en ligne capable de le faire était: http://jsonviewer.stack.hu/ .
Je dois cependant l'utiliser depuis Python.
Ceci est mon jeu de données:

A partir de la ligne de commande:
echo '{"one":1,"two":2}' | python -mjson.tool
qui produit:
{
"one": 1,
"two": 2
}
Par programmation, le Python manuel décrit le JSON en jolie impression :
>>> import json
>>> print json.dumps({'4': 5, '6': 7}, sort_keys=True, indent=4)
{
"4": 5,
"6": 7
}
Utilisez l'argument indent de la fonction dumps dans le module json .
De la docs:
>>> import json
>>> print json.dumps({'4': 5, '6': 7}, sort_keys=True, indent=4)
{
"4": 5,
"6": 7
}
Une solution in-python minimale qui colore les données JSON fournies via la ligne de commande:
import sys
import json
from pygments import highlight, lexers, formatters
formatted_json = json.dumps(json.loads(sys.argv[1]), indent=4)
colorful_json = highlight(unicode(formatted_json, 'UTF-8'), lexers.JsonLexer(), formatters.TerminalFormatter())
print(colorful_json)
Inspiré par pjson mentionné ci-dessus. Ce code nécessite que pygments soit installé.
Exemple de sortie:
Essayez nderscore-cli :
cat myfile.json | underscore print --color
C'est un outil très astucieux qui peut élégamment faire beaucoup de manipulations de données structurées, exécuter des extraits JS, des modèles de remplissage, etc. Il est ridiculement bien documenté, poli et prêt pour une utilisation sérieuse. Et je l'ai écrit. :)
La commande cli que j'ai utilisée avec python pour cela est la suivante:
cat myfile.json | python -mjson.tool
Vous devriez pouvoir trouver plus d'informations ici:
Il semble que jsbeautifier ait ouvert ses outils et les ait empaquetés sous la forme Python et les bibliothèques JS, et en tant qu'outils de la CLI. Il ne ressemble pas à un service Web, mais je n'ai pas vérifié de trop près. Voir le repo de github avec les instructions d'installation.
Depuis leurs documents pour Python utilisation de la CLI et de la bibliothèque:
Pour embellir en utilisant python:
$ pip install jsbeautifier
$ js-beautify file.js
La sortie embellie va à stdout.
Utiliser jsbeautifier comme bibliothèque est simple:
import jsbeautifier
res = jsbeautifier.beautify('your javascript string')
res = jsbeautifier.beautify_file('some_file.js')
... ou, pour spécifier certaines options:
opts = jsbeautifier.default_options()
opts.indent_size = 2
res = jsbeautifier.beautify('some javascript', opts)
Si vous souhaitez passer une chaîne au lieu d'un nom de fichier et que vous utilisez bash, vous pouvez utiliser la substitution de processus comme suit:
$ js-beautify <(echo '{"some": "json"}')
alias jsonp='pbpaste | python -m json.tool'
Ce sera assez imprimer JSON qui est sur le presse-papiers dans OSX. Il suffit de le copier, puis d’appeler l’alias à partir d’une invite Bash.
Vous pouvez diriger la sortie vers jq . Si vous python contient quelque chose comme
print json.dumps(data)
alors vous pouvez tirer:
python foo.py | jq '.'
Première installation de pygments
puis
echo '<some json>' | python -m json.tool | pygmentize -l json
Utiliser la bibliothèque d'outils python
Ligne de commande: python -mjson.tool
Vos données sont mal formées. Les champs de valeur en particulier comportent de nombreux espaces et de nouvelles lignes. Les formateurs automatisés ne fonctionneront pas, car ils ne modifieront pas les données réelles. Lorsque vous générez les données pour la sortie, filtrez-les au besoin pour éviter les espaces.
Avec jsonlint (comme xmllint):
aptitude install python-demjson
jsonlint -f foo.json
