from playwright.sync_api import Playwright, sync_playwright, expect
def run(playwright: Playwright) -> None:
browser = playwright.chromium.launch(headless=False,slow_mo=1000)
context = browser.new_context()
page = context.new_page()
page.goto("https://www.baidu.com/")
page.locator("#kw").click()
page.locator("#kw").fill("阿森纳")
page.get_by_role("button", name="百度一下").click()
page.screenshot(path='1.jpg',full_page=True)
# ---------------------
context.close()
browser.close()
with sync_playwright() as playwright:
run(playwright)
slow_mo=1000 为延时参数，可以理解为sleep。
full_page=Ture 为截取长图，默认为False。
浏览器非静默运行browser = playwright.chromium.launch(headless=False)
浏览器静默运行：browser = playwright.chromium.launch(headless=True)
浏览器默认语言为英语：context = browser.new_context(locale='en-US')
