如何在Svelte和Sapper中使用cookies？

// 设置cookie
export function setCookie(name, value, days) {
  const date = new Date();
  date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
  const expires = "expires=" + date.toUTCString();
  document.cookie = name + "=" + value + ";" + expires + ";path=/";
}

// 获取cookie
export function getCookie(name) {
  const cookieName = name + "=";
  const cookies = document.cookie.split(';');
  for (let i = 0; i < cookies.length; i++) {
    let cookie = cookies[i];
    while (cookie.charAt(0) === ' ') {
      cookie = cookie.substring(1);
    }
    if (cookie.indexOf(cookieName) === 0) {
      return cookie.substring(cookieName.length, cookie.length);
    }
  }
  return "";
}

import { setCookie, getCookie } from '../utils/cookies';

// 设置cookie
setCookie("username", "John Doe", 7);

// 获取cookie
const username = getCookie("username");
console.log(username); // 输出：John Doe

import { setCookie, getCookie } from '../utils/cookies';

export function get(req, res, next) {
  // 设置cookie
  setCookie("username", "John Doe", 7);

  // 获取cookie
  const username = getCookie("username");
  console.log(username); // 输出：John Doe

  res.end(JSON.stringify({ username }));
}
