如何将结构保存为扁平化的json？

import json

def flatten_structure(data, parent_key='', sep='.'):
    flattened_data = {}
    for key, value in data.items():
        new_key = f"{parent_key}{sep}{key}" if parent_key else key
        if isinstance(value, dict):
            flattened_data.update(flatten_structure(value, new_key, sep))
        else:
            flattened_data[new_key] = value
    return flattened_data

# 原始结构
structure = {
    'person': {
        'name': 'John',
        'age': 30,
        'address': {
            'street': '123 Main St',
            'city': 'New York'
        }
    },
    'company': 'ABC Inc'
}

# 将结构扁平化
flattened_structure = flatten_structure(structure)

# 序列化为JSON
json_data = json.dumps(flattened_structure)

print(json_data)

{
    "person.name": "John",
    "person.age": 30,
    "person.address.street": "123 Main St",
    "person.address.city": "New York",
    "company": "ABC Inc"
}
