如何获取JSON数据索引中的所有可用JSON数据

import json

def extract_json_data(json_data):
    extracted_data = []
    
    def traverse_json(data):
        if isinstance(data, dict):
            for key, value in data.items():
                if isinstance(value, (dict, list)):
                    traverse_json(value)
                else:
                    # 判断是否为可用数据的条件，这里以非空字符串为例
                    if value != "":
                        extracted_data.append(value)
        elif isinstance(data, list):
            for item in data:
                traverse_json(item)
    
    traverse_json(json_data)
    return extracted_data

# 示例JSON数据
json_str = '''
{
    "name": "John",
    "age": 30,
    "address": {
        "street": "123 Main St",
        "city": "New York"
    },
    "hobbies": ["reading", "music", "sports"],
    "skills": {
        "programming": "Python",
        "web": "HTML/CSS"
    }
}
'''

# 解析JSON数据
json_data = json.loads(json_str)

# 获取所有可用JSON数据
available_data = extract_json_data(json_data)

# 打印结果
for data in available_data:
    print(data)
