如何在 Python 中美化 JSON？

有人能建议我如何用 Python 或通过命令行美化 JSON 吗？

唯一可以做到这一点的在线 JSON 美化器是: http://jsonviewer.stack.hu/。

但是，我需要在 Python 内部使用它。

这是我的数据集:

从命令行:

echo '{"one":1,"two":2}' | python -mjson.tool

产出:

{
"one": 1,
"two": 2
}

从编程上讲，Python 手册描述打印漂亮的 JSON:

>>> import json
>>> print json.dumps({'4': 5, '6': 7}, sort_keys=True, indent=4)
{
"4": 5,
"6": 7
}

我在 python 中使用的 cli 命令是:

cat myfile.json | python -mjson.tool

使用 python 工具库

命令行: python-mjson.tool

使用 Json 模块中 dumps函数的 indent参数。

来自文件:

>>> import json
>>> print json.dumps({'4': 5, '6': 7}, sort_keys=True, indent=4)
{
"4": 5,
"6": 7
}

您的数据格式不正确。值字段具有许多空格和新行。自动格式化程序不能处理这个问题，因为它们不会修改实际的数据。在生成用于输出的数据时，根据需要对其进行筛选，以避免使用空格。

小开

alias jsonp='pbpaste | python -m json.tool'

这将很好地打印 OSX 中剪贴板上的 JSON。只需复制它，然后从 Bash 提示符调用别名。

试试下划线-cli:

cat myfile.json | underscore print --color

它是一个非常漂亮的工具，可以优雅地对结构化数据进行大量操作，执行 js 片段，填充模板等等。它有很好的文档记录，经过精心打磨，可以认真使用。是我写的。:)

您可以将输出通过管道发送到 jq

print json.dumps(data)

然后你就可以开枪了:

python foo.py | jq '.'

使用 jsonlint (如 xmllint) :

aptitude install python-demjson
jsonlint -f foo.json

一个最小的 python 内部解决方案，通过命令行提供 json 数据:

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)

灵感来自于上面提到的 pjson。这个代码需要安装 pygments。

看起来美容师开源了它们的工具，并将它们打包为 Python 和 JS 库以及 CLI 工具。看起来他们没有呼叫网络服务，但是我没有仔细检查。请参阅带有安装说明的 Github Repo。

来自 Python CLI 和库使用的文档:

使用 python 美化:

$ pip install jsbeautifier
$ js-beautify file.js

美化输出到 stdout。

使用 jsbeautifier作为库很简单:

import jsbeautifier
res = jsbeautifier.beautify('your javascript string')
res = jsbeautifier.beautify_file('some_file.js')

... 或者，指定一些选项:

opts = jsbeautifier.default_options()
opts.indent_size = 2
res = jsbeautifier.beautify('some javascript', opts)

如果您想传递一个字符串而不是文件名，并且您正在使用 bash，那么您可以像下面这样使用进程替换:

$ js-beautify <(echo '{"some": "json"}')

首先安装 pygments

那么

echo '<some json>' | python -m json.tool | pygmentize -l json

我不喜欢 json.dump (...)-> 的输出，因为我觉得换行太多了。我不想使用命令行工具或者安装什么东西。我终于找到了 Python 印刷品(= pretty print)。不幸的是，它不能生成正确的 JSON，但是我认为对存储的数据进行用户友好的扫描是有用的。

json.dumps(json_dict, indent=4)输出

{
"hyperspace": {
"constraints": [],
"design": [
[
"windFarm.windparkSize.k",
"continuous",
[
0,
0,
5
]
],
[
"hydroPlant.primaryControlMax",
"continuous",
[
100,
300
]
]
],
"kpis": [
"frequency.y",
"city.load.p[2]"
]
},
"lhc_size": 10,
"number_of_runs": 10
}

Pprint 的用法:

import pprint


json_dict = {"hyperspace": {"constraints": [], "design": [["windFarm.windparkSize.k", "continuous", [0, 0, 5]], ["hydroPlant.primaryControlMax", "continuous", [100, 300]]], "kpis": ["frequency.y", "city.load.p[2]"]}, "lhc_size": 10, "number_of_runs": 10}


formatted_json_str = pprint.pformat(json_dict)
print(formatted_json_str)
pprint.pprint(json_dict)

pprint.pformat(...)或 pprint.pprint(...)的测试结果:

{'hyperspace': {'constraints': [],
'design': [['windFarm.windparkSize.k', 'continuous', [0, 0, 5]],
['hydroPlant.primaryControlMax',
'continuous',
[100, 300]]],
