如何迭代和提取json数组中的url字符串

import json
import re

def extract_urls_from_json(json_str):
    data = json.loads(json_str)
    
    urls = []
    extract_urls(data, urls)
    
    return urls

def extract_urls(data, urls):
    if isinstance(data, list):
        for item in data:
            extract_urls(item, urls)
    elif isinstance(data, dict):
        for key, value in data.items():
            extract_urls(value, urls)
    elif isinstance(data, str):
        if re.match(r'^https?://(?:[-\w.]|(?:%[\da-fA-F]{2}))+$', data):
            urls.append(data)

# 示例JSON数组
json_str = '[{"name": "example", "url": "https://example.com"}, {"name": "google", "url": "https://google.com"}]'

# 提取URL
urls = extract_urls_from_json(json_str)

# 打印提取到的URL
for url in urls:
    print(url)
