指定 channel 打开浏览器
默认情况下，chromium.launch() 不带 channel 参数打开的是 chromium 浏览器
from playwright.sync_api import sync_playwright
# 上海悠悠 wx:283340479
# blog:https://www.cnblogs.com/yoyoketang/
with sync_playwright() as pw:
browser = pw.chromium.launch(headless=False)
page = browser.new_page()
page.goto("https://www.baidu.com/")
Google Chrome 和 Microsoft Edge浏览器都是用的 chromium 内核，所以只需加一个channel="chrome" 即可打开谷歌浏览器
from playwright.sync_api import sync_playwright
# 上海悠悠 wx:283340479
# blog:https://www.cnblogs.com/yoyoketang/
with sync_playwright() as pw:
browser = pw.chromium.launch(headless=False, channel="chrome")
page = browser.new_page()
page.goto("https://www.baidu.com/")
添加 channel="msedge" 即可打开Microsoft Edge浏览器
from playwright.sync_api import sync_playwright
# 上海悠悠 wx:283340479
# blog:https://www.cnblogs.com/yoyoketang/
with sync_playwright() as pw:
browser = pw.chromium.launch(headless=False, channel="msedge")
page = browser.new_page()
page.goto("https://www.baidu.com/")
