js 如何获取session

// 获取所有Cookie
function getAllCookies() {
    const cookies = {};
    const cookieStr = document.cookie;
    const cookieArray = cookieStr.split('; ');
    for (const cookie of cookieArray) {
        const [name, value] = cookie.split('=');
        cookies[name] = value;
    }
    return cookies;
}

// 获取sessionid
const sessionId = getAllCookies()['sessionid'];
console.log('Session ID:', sessionId);

// 存储会话信息
localStorage.setItem('sessionId', 'your-session-id');

// 获取会话信息
const sessionId = localStorage.getItem('sessionId');
console.log('Session ID:', sessionId);
