js cookie序列化

// Cookie对象
const cookie = {
    name: 'sessionId',
    value: '1234567890',
    expires: new Date(Date.now() + 3600000), // 1小时后过期
    path: '/',
    domain: 'example.com',
    secure: true,
    httpOnly: true
};

// 序列化为字符串
function serializeCookie(cookie) {
    let cookieStr = `${encodeURIComponent(cookie.name)}=${encodeURIComponent(cookie.value)}`;
    if (cookie.expires) {
        cookieStr += `; Expires=${cookie.expires.toUTCString()}`;
    }
    if (cookie.path) {
        cookieStr += `; Path=${cookie.path}`;
    }
    if (cookie.domain) {
        cookieStr += `; Domain=${cookie.domain}`;
    }
    if (cookie.secure) {
        cookieStr += '; Secure';
    }
    if (cookie.httpOnly) {
        cookieStr += '; HttpOnly';
    }
    return cookieStr;
}

const serializedCookie = serializeCookie(cookie);
console.log(serializedCookie);

// 反序列化示例（简化版）
function deserializeCookie(cookieStr) {
    const cookieParts = cookieStr.split(';').map(part => part.trim());
    const [name, value] = cookieParts[0].split('=').map(decodeURIComponent);
    const cookie = { name, value };

    cookieParts.slice(1).forEach(part => {
        const [key, val] = part.split('=').map(decodeURIComponent);
        if (key === 'Expires') {
            cookie.expires = new Date(val);
        } else if (key === 'Path') {
            cookie.path = val;
        } else if (key === 'Domain') {
            cookie.domain = val;
        } else if (key === 'Secure') {
            cookie.secure = true;
        } else if (key === 'HttpOnly') {
            cookie.httpOnly = true;
        }
