源代码怎么批量改域名

import os
import re

def batch_replace_domain(directory, old_domain, new_domain):
    for root, dirs, files in os.walk(directory):
        for file in files:
            if file.endswith(".html") or file.endswith(".php"):
                file_path = os.path.join(root, file)
                with open(file_path, 'r', encoding='utf-8') as f:
                    content = f.read()
                
                # 使用正则表达式替换域名
                new_content = re.sub(r'(' + re.escape(old_domain) + ')', new_domain, content)
                
                with open(file_path, 'w', encoding='utf-8') as f:
                    f.write(new_content)

# 示例用法
batch_replace_domain('/path/to/your/project', 'old.example.com', 'new.example.com')
