如何将 MultiDict 转换为嵌套字典

How to convert a MultiDict to nested dictionary(如何将 MultiDict 转换为嵌套字典)

问题描述

我想从 Webob 转换 POST MultiDict 到嵌套字典.例如

I would like to convert a POST from Webob MultiDict to nested dictionary. E.g.

因此来自以下帖子:

'name=Kyle&phone.number=1234&phone.type=home&phone.number=5678&phone.type=work'

到多项式；

[('name', 'Kyle'), ('phone.number', '1234'), ('phone.type', 'home'), ('phone.number', '5678'), ('phone.type', 'work')]

到嵌套字典

{'name': 'Kyle',
 'phone': [
  {
    'number': '12345',
    'type': 'home',
  },{
    'number': '5678',
    'type': 'work',
  },

有什么想法吗?

编辑

我最终从 Will 发布的 formencode 包中提取了 variable_decode 方法.唯一需要的更改是使列表显式，例如

I ended up extracting the variable_decode method from the formencode package as posted by Will. The only change that was required is to make the lists explicit, E.g.

'name=Kyle&phone-1.number=1234&phone-1.type=home&phone-2.number=5678&phone-2.type=work'

哪个更好，原因有很多.

Which is better for many reasons.
