Cookie

Puppeteer 提供了通过直接操作浏览器存储来提前获取、设置和删除 Cookie 的方法。如果你需要在测试中保存和恢复特定的 Cookie，这会很有用。

获取 Cookie

以下示例演示了如何获取浏览器默认 BrowserContext 中可用的 Cookie。

import puppeteer from 'puppeteer';

const browser = await puppeteer.launch();

const page = await browser.newPage();

await page.goto('https://example.com');

// In this example, we set a cookie using script evaluation.
// Cookies can be set by the page/server in various ways.
await page.evaluate(() => {
  document.cookie = 'myCookie = MyCookieValue';
});

console.log(await browser.cookies()); // print available cookies.

设置 Cookie

Puppeteer 也可以将 Cookie 直接写入浏览器的存储：

import puppeteer from 'puppeteer';

const browser = await puppeteer.launch();

// Sets two cookies for the localhost domain.
await browser.setCookie(
  {
    name: 'cookie1',
    value: '1',
    domain: 'localhost',
    path: '/',
    expires: -1,
    httpOnly: false,
    secure: false,
    sourceScheme: 'NonSecure',
  },
  {
    name: 'cookie2',
    value: '2',
    domain: 'localhost',
    path: '/',
    expires: -1,
    httpOnly: false,
    secure: false,
    sourceScheme: 'NonSecure',
  },
);

console.log(await browser.cookies()); // print available cookies.

删除 Cookie

Browser.deleteCookie() 方法允许从存储中删除 Cookie。

import puppeteer from 'puppeteer';

const browser = await puppeteer.launch();

// Deletes two cookies for the localhost domain.
await browser.deleteCookie(
  {
    name: 'cookie1',
    value: '1',
    domain: 'localhost',
    path: '/',
    expires: -1,
    httpOnly: false,
    secure: false,
    sourceScheme: 'NonSecure',
  },
  {
    name: 'cookie2',
    value: '2',
    domain: 'localhost',
    path: '/',
    expires: -1,
    httpOnly: false,
    secure: false,
    sourceScheme: 'NonSecure',
  },
);

console.log(await browser.cookies()); // print available cookies.

除了操作默认浏览器上下文的 Browser 方法之外，BrowserContext 类上也提供相同的方法。
