如何设置 Pyppeteer 视口大小（屏幕大小）

在 Pyppeteer 中设置视口大小（例如为了获取 Full HD 截图）就像这样简单

pyppeteer_viewport.py

browser = await launch({
    "defaultViewport": {"width": 1920, "height": 1080},
})

完整示例

pyppeteer_viewport_full_example.py

#!/usr/bin/env python3
import asyncio
from pyppeteer import launch

async def main():
    browser = await launch({
        "defaultViewport": {"width": 1920, "height": 1080},
    })
    page = await browser.newPage()
    await page.goto('https://www.techoverflow.net', {'waitUntil': 'networkidle2'})
    # 截图
    await page.screenshot({'path': 'screenshot.png'})
    # Cleanup
    await browser.close()

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