Puppeteer 轮换代理：按页面、上下文还是浏览器

import puppeteer from 'puppeteer'

const proxies = [
  { server: 'http://HOST1:2222', username: 'LOGIN1', password: 'PASSWORD1' },
  { server: 'http://HOST2:2222', username: 'LOGIN2', password: 'PASSWORD2' },
]

const browser = await puppeteer.launch()
for (const p of proxies) {
  const context = await browser.createBrowserContext({ proxyServer: p.server })
  const page = await context.newPage()
  await page.authenticate({ username: p.username, password: p.password })
  await page.goto('https://ipinfo.io/json')
  console.log(await page.evaluate(() => document.body.innerText))
  await context.close()
}
await browser.close()

import puppeteer from 'puppeteer'
import { anonymizeProxy, closeAnonymizedProxy } from 'proxy-chain'

const localUrl = await anonymizeProxy('http://LOGIN:PASSWORD@HOST:2222')
const browser = await puppeteer.launch({ args: [`--proxy-server=${localUrl}`] })
const page = await browser.newPage()
await page.goto('https://ipinfo.io/json')
console.log(await page.evaluate(() => document.body.innerText))
await browser.close()
await closeAnonymizedProxy(localUrl, true)

import puppeteer from 'puppeteer'

const browser = await puppeteer.launch({

})
for (let i = 0; i < 3; i++) {
  const page = await browser.newPage()
  await page.authenticate({ username: 'LOGIN', password: 'PASSWORD' })
  await page.goto('https://ipinfo.io/json')
  console.log(await page.evaluate(() => document.body.innerText))
