Playwright自动化模拟浏览器点击

palywright相关文章

playwright文档

# 安装playwright库
pip install playwright

# 安装浏览器驱动文件(安装过程稍微有点慢)
python -m playwright install

# 命令行键入 --help 可看到所有选项
python -m playwright codegen

-o:将录制的脚本保存到一个文件

--target:规定生成脚本的语言,有JS和Python两种,默认为Python

-b:指定浏览器驱动

playwright demo

python -m playwright codegen --target python -o \'my.py\' -b chromium https://www.baidu.com

同步依次打开三个浏览器,前往baidu搜索,截图后退出。

from playwright import sync_playwright

with sync_playwright() as p:
    for browser_type in [p.chromium, p.firefox, p.webkit]:
        browser = browser_type.launch()
        page = browser.newPage()
        page.goto(\'https://baidu.com/\')
        page.screenshot(path=f\'example-{browser_type.name}.png\')
        browser.close()

异步异步操作可结合asyncio同时进行三个浏览器操作。

import asyncio
from playwright import async_playwright

async def main():
    async with async_playwright() as p:
        for browser_type in [p.chromium, p.firefox, p.webkit]:
            browser = await browser_type.launch()
            page = await browser.newPage()
            await page.goto(\'http://baidu.com/\')
            await page.screenshot(path=f\'example-{browser_type.name}.png\')
            await browser.close()

asyncio.get_event_loop().run_until_complete(main())

移动端更厉害的是,playwright还可支持移动端的浏览器模拟。 下面是官方文档提供的一段代码,模拟在给定地理位置上手机iphone 11 pro上的Safari浏览器,首先导航到maps.google.com,然后执行定位并截图。

from playwright import sync_playwright

with sync_playwright() as p:
    iphone_11 = p.devices[\'iPhone 11 Pro\']
    browser = p.webkit.launch(headless=False)
    context = browser.newContext(
        **iphone_11,
        locale=\'en-US\',
        geolocation={ \'longitude\': 12.492507, \'latitude\': 41.889938 },
        permissions=[\'geolocation\']
    )
    page = context.newPage()
    page.goto(\'https://maps.google.com\')
    page.click(\'text="Your location"\')
    page.screenshot(path=\'colosseum-iphone.png\')
    browser.close()
