json下划线转驼峰

你可以使用以下的函数将 JSON 中的下划线转换为驼峰命名法：

import re

def underscore_to_camelcase(word):
    return re.sub(r'_(\w)', lambda m: m.group(1).upper(), word)

def convert_keys_to_camelcase(data):
    if isinstance(data, dict):
        new_data = {}
        for key, value in data.items():
            new_key = underscore_to_camelcase(key)
            new_value = convert_keys_to_camelcase(value)
            new_data[new_key] = new_value
        return new_data
    elif isinstance(data, list):
        return [convert_keys_to_camelcase(item) for item in data]
    else:
        return data

你可以将 JSON 数据作为参数传递给 `convert_keys_to_camelcase` 函数，它将递归地遍历 JSON 数据并将所有的键转换为驼峰命名法。例如：

import json

json_data = '{"first_name": "John", "last_name": "Doe", "age": 30}'
data = json.loads(json_data)
camelcased_data = convert_keys_to_camelcase(data)
camelcased_json = json.dumps(camelcased_data)
print(camelcased_json)

输出结果将会是：

{"firstName": "John", "lastName": "Doe", "age": 30}
