因为一些特殊场景的需要，需要将接口的json返回渲染成markdown形式，自己处理的话还挺麻烦的，俗话说的好：站在巨人的肩膀上。下面介绍了基于Python的Json与Markdown互相转换的方式，当然你可以在Github上多搜搜看看其它的方案。

一、Json转Markdown

1、原始torsimany库

https://github.com/PolBaladas/torsimany

 安装依赖库：torsimany

pip3 install torsimany

使用方式：

python3 torsimany.py [JSON_FILE].json
 
或者
 
torsimany [JSON_FILE].json

假设我们有个Json格式文件：products.json，内容如下：

{
        "name":"Product",
        "properties":
        {
                "id":
                {
                        "type":"number",
                        "description":"Product identifier",
                        "required":true
                },
                "name":
                {
                        "description":"Name of the product",
                        "type":"string",
                        "required":true
                },
                "price":
                {
                        "type":"number",
                        "minimum":0,
                        "required":true
                },
                "tags":
                {
                        "type":"array",
                        "items":
                        {
                        "type":"string"
                        }
                }
        }
}

我们在终端执行如下命令，将其转化为Markdown格式文件：

torsimany products.json

如果在Python3报错：AttributeError: 'str' object has no attribute 'decode'

解决方法：可以尝试修改下安装包对应的文件：./site-packages/torsimany/torsimany.py，修改内容如下：

预期成功的话，会在当前目录生成：products.markdown文件，也就是markdown形式的文件，内容如下：

  * name: Product
# Properties #
* ## Id ##
  * type: number
  * description: Product identifier
  * required: True
* ## Name ##
  * description: Name of the product
  * type: string
  * required: True
* ## Price ##
  * type: number
  * minimum: 0
  * required: True
* ## Tags ##
  * type: array
* ### Items ###
  * type: string

我们通过Markdown在线工具查看效果，大概如下：

2、torsimany库修改

上述的torsimany库默认只支持文件形式的转换，其实我们日常用的比较多的是直接在线转换json文件为mardkdown的形式，于是对上面的实现进行了一些简单的改动，其实也比较简单，就一个文件，json2markdown.py

试运行下，结果如下：

$ python3 json2markdown.py 
  * scene: 气泡触发次数过高(1小时)
# Data #
  * scene: 重点人触发气泡过多(1小时)
# Data #
  * scene: 某一气泡CTR过低(1天)
# Data #
* 0: 马家春慢#0#60#0.0
* 1: 法曲献仙音#1#135#0.007
* 2: 月宫春#0#91#0.0
* 3: 海棠花令#0#97#0.0

二、Markdown转Json

https://github.com/njvack/markdown-to-json

安装依赖库：markdown-to-json

pip3 install markdown-to-json

使用方法：

$ md_to_json -h
Translate markdown into JSON.
 
Usage:
  md_to_json [options] <markdown_file>
  md_to_json -h | --help
 
Options:
  -h --help     Show this screen
  --version     Print version number
  -o <file>     Save output to a file instead of stdout
  -i <val>      Indent nested JSON by this amount. Use a negative number for
                most compact possible JSON. the [default: 2]

我们以products.markdown文件为例（上文生成的），命令如下，当然也可以通过-o指定写入到生成的文件。

$ md_to_json products1.markdown
 
# 输出结果
{
  "Properties": [
    "Id",
    [
      "type: number",
      "description: Product identifier",
      "required: True"
    ],
    "Name",
    [
      "description: Name of the product",
      "type: string",
      "required: True"
    ],
    "Price",
    [
      "type: number",
      "minimum: 0",
      "required: True"
    ],
    "Tags",
    [
      "type: array"
    ],
    "Items",
    [
      "type: string"
    ]
  ]
}
