Playwrightでプロキシを使う方法

# pip install playwright && playwright install chromium
from playwright.sync_api import sync_playwright

with sync_playwright() as p:
    browser = p.chromium.launch(proxy={
        "server": "http://HOST:PORT",
        "username": "USERNAME",
        "password": "PASSWORD",
    })
    page = browser.new_page()
    page.goto("https://example.com/")
    print(page.title())
    browser.close()

// npm i playwright && npx playwright install chromium
const { chromium } = require('playwright');

(async () => {
  const browser = await chromium.launch({
    proxy: {
      server: 'http://HOST:PORT',
      username: 'USERNAME',
      password: 'PASSWORD',
    },
  });
  const page = await browser.newPage();
  await page.goto('https://example.com/');
  console.log(await page.title());
  await browser.close();
})();

from playwright.sync_api import sync_playwright

with sync_playwright() as p:
    browser = p.chromium.launch()
    # The proxy belongs to this context only; another context can use
    # a different address, or none.
    context = browser.new_context(proxy={
        "server": "http://HOST:PORT",
        "username": "USERNAME",

    })
    page = context.new_page()

    browser.close()

# Switch the proxy to SOCKS5 and put your machine's IP on its whitelist:
# Chromium cannot send a SOCKS5 username and password.

    print(page.title())
    browser.close()

# Put the public IPv4 address your code runs from on the proxy's
# whitelist. Replaces the list; an empty list turns whitelisting off
# and the proxy falls back to username and password.
