playwright中处理cookie的几种实现方法

const { chromium } = require('playwright');

(async () => {
  const browser = await chromium.launch();
  const context = await browser.newContext();
  
  // 添加单个 Cookie
  await context.addCookies([{
    name: 'token',
    value: 'abc123',
    url: 'https://example.com', // 或使用 domain/path
    domain: 'example.com',
    path: '/',
    expires: Math.floor(Date.now() / 1000) + 86400, // 过期时间（Unix 时间戳）
    httpOnly: true,
    secure: true,
    sameSite: 'Lax' // 'Strict' | 'Lax' | 'None'
  }]);
})();

// 获取所有 Cookie
const cookies = await context.cookies();
console.log(cookies);

// 获取特定 URL 的 Cookie
const siteCookies = await context.cookies(['https://example.com/login']);

// 清除所有 Cookie
await context.clearCookies();

// 清除特定 Cookie（通过名称）
await context.addCookies([]); // 添加空数组无法清除，需手动过滤重置

await context.storageState({ path: 'auth.json' });

const context = await browser.newContext({
  storageState: 'auth.json'
});

await context.route('**/*', route => {
  const headers = route.request().headers();
  headers['Cookie'] = 'my_cookie=value'; // 手动添加 Cookie 到请求
  route.continue({ headers });
});

const cookieValue = await page.evaluate(() => {
  return document.cookie; // 读取全部 Cookie
});

await page.evaluate(() => {
  document.cookie = 'user=john; expires=Thu, 18 Dec 2025 12:00:00 UTC; path=/';
});

// 首次登录并保存状态
const context = await browser.newContext();
await context.addInitScript(() => {
  localStorage.setItem('theme', 'dark');
});
await page.goto('https://example.com/login');
await page.fill('#username', 'user');
await page.fill('#password', 'pass');
await page.click('#login');
await context.storageState({ path: 'auth.json' });

// 后续测试直接加载状态
const newContext = await browser.newContext({ storageState: 'auth.json' });
const newPage = await newContext.newPage();
await newPage.goto('https://example.com/dashboard'); // 已登录状态
