从URL获取Wordpress帖子的发布日期

from urllib.parse import urlparse, parse_qs
from datetime import datetime

def get_wordpress_post_date(url):
    parsed_url = urlparse(url)
    query_params = parse_qs(parsed_url.query)
    
    if 'p' in query_params:
        post_id = query_params['p'][0]
        # 根据post_id进行相应的处理，如查询数据库获取发布日期
        # 示例中直接返回post_id作为发布日期
        return post_id
    
    # 如果URL中没有查询参数，则尝试从路径中提取日期信息
    path_parts = parsed_url.path.split('/')
    date_parts = [part for part in path_parts if part.isdigit()]
    
    if len(date_parts) >= 3:
        year = int(date_parts[0])
        month = int(date_parts[1])
        day = int(date_parts[2])
        # 构造日期对象
        post_date = datetime(year, month, day)
        return post_date.strftime('%Y-%m-%d')
    
    # 如果无法提取到发布日期，则返回空值或其他默认值
    return None

# 示例用法
url = 'https://example.com/2022/01/01/sample-post'
post_date = get_wordpress_post_date(url)
print(post_date)  # 输出：2022-01-01
