清除属性文件中的所有属性值

import re

def clear_properties(file_path):
    properties = {}
    
    # 读取属性文件
    with open(file_path, 'r') as file:
        lines = file.readlines()
    
    # 解析属性文件内容为键值对
    for line in lines:
        match = re.match(r'^\s*([^=]+)\s*=\s*(.*)\s*$', line)
        if match:
            key = match.group(1)
            value = match.group(2)
            properties[key] = value
    
    # 清除属性值
    for key in properties:
        properties[key] = ''
    
    # 将更新后的属性写入文件
    with open(file_path, 'w') as file:
        for key, value in properties.items():
            file.write(f'{key}={value}\n')
