当我没有访问权限或没有可用的信息时，有没有办法跳过URL (Json文件

import requests

urls = ['http://example.com/api1', 'http://example.com/api2', 'http://example.com/api3']  # 假设这是您要处理的URL列表

for url in urls:
    try:
        response = requests.get(url)
        response.raise_for_status()  # 如果响应状态码不是200，将抛出异常

        json_data = response.json()
        
        # 假设我们只处理包含特定键的Json对象
        if 'key' not in json_data:
            print(f"Skipping {url}: Missing 'key' in Json data.")
            continue

        # 在这里处理有效的Json数据
        print(f"Processing {url}: {json_data}")

    except requests.exceptions.HTTPError as http_err:
        print(f"Skipping {url} due to HTTP error: {http_err}")
    except requests.exceptions.RequestException as req_err:
        print(f"Skipping {url} due to request error: {req_err}")
    except ValueError as val_err:  # 包括Json解析错误
        print(f"Skipping {url} due to invalid Json: {val_err}")
