如何在本地存储(或cookie)中保存令牌？

// 存储令牌
localStorage.setItem('token', 'your_token_value');

// 获取令牌
const token = localStorage.getItem('token');

// 删除令牌
localStorage.removeItem('token');

// 设置令牌cookie
document.cookie = 'token=your_token_value; expires=Fri, 31 Dec 9999 23:59:59 GMT; path=/';

// 获取令牌
const cookies = document.cookie.split(';');
let token = '';
cookies.forEach(cookie => {
  if (cookie.trim().startsWith('token=')) {
    token = cookie.split('=')[1];
  }
});

// 删除令牌cookie
document.cookie = 'token=; expires=Thu, 01 Jan 1970 00:00:00 GMT; path=/;';
