使用Python将JSON嵌套到平面JSON

import json

def flatten_json(nested_json, parent_key='', sep='.'):
    """
    将嵌套JSON转换为平面JSON
    """
    flattened_json = {}
    for k, v in nested_json.items():
        new_key = f"{parent_key}{sep}{k}" if parent_key else k
        if isinstance(v, dict):
            flattened_json.update(flatten_json(v, new_key, sep=sep))
        else:
            flattened_json[new_key] = v
    return flattened_json

# 嵌套JSON示例
nested_json = {
    "name": "John",
    "age": 30,
    "address": {
        "street": "123 Street",
        "city": "New York",
        "state": "NY"
    }
}

# 将嵌套JSON转换为平面JSON
flattened_json = flatten_json(nested_json)

# 打印平面JSON
print(json.dumps(flattened_json, indent=4))

{
    "name": "John",
    "age": 30,
    "address.street": "123 Street",
    "address.city": "New York",
    "address.state": "NY"
}
