将 json 转储到 yaml

2022-01-14 00:00:00 python json encoding yaml

问题描述

我有一个 .json 文件(将其命名为 meta.json)，如下所示:

I got a .json file (named it meta.json) like this:

{
    "main": {
        "title": "今日は雨が降って",
        "description": "今日は雨が降って"
    }
}

我想将其转换为 .yaml 文件(将其命名为 meta.yaml)，例如:

I would like to convert it to a .yaml file (named it meta.yaml) like :

title: "今日は雨が降って"
description: "今日は雨が降って"

我所做的是:

import simplejson as json
import pyyaml

f = open('meta.json', 'r')
jsonData = json.load(f)
f.close()

ff = open('meta.yaml', 'w+')
yamlData = {'title':'', 'description':''}
yamlData['title'] = jsonData['main']['title']
yamlData['description'] = jsonData['main']['description']
yaml.dump(yamlData, ff)
# So you can  see that what I need is the value of meta.json

但遗憾的是，我得到的是以下内容:

But sadly, what I got is following: 

{description: "u4ECAu65E5u306Fu96E8u304Cu964Du3063u3066", title: "u4ECAu65E5
u306Fu96E8u304Cu964Du3063"}

为什么?

解决方案

pyyaml.dump() 有 "allow_unicode" 选项，默认为 None，输出中的所有非 ASCII 字符都被转义.如果 allow_unicode=True 则写入原始 unicode 字符串.

pyyaml.dump() has "allow_unicode" option, it's default is None, all non-ASCII characters in the output are escaped. If allow_unicode=True write raw unicode strings.

yaml.dump(data, ff, allow_unicode=True)

json.dump(data, outfile, ensure_ascii=False)
