import pyppeteer
import asyncio
from pyppeteer.network_manager import Request, Response

async def req_intercept(req: Request):
    print(f'Original header: {req.headers}')
    req.headers.update({'Accept-Encoding': 'gzip'})
    await req.continue_(overrides={'headers': req.headers})

async def resp_intercept(resp: Response):
    print(f"New header: {resp.request.headers}")


async def test():
    browser = await pyppeteer.launch()
    page = await browser.newPage()
    await page.setRequestInterception(True)
    page.on('request', req_intercept)
    page.on('response', resp_intercept)
    resp = await page.goto('https://example.org/')
    print(resp.headers)

asyncio.get_event_loop().run_until_complete(test())

结果：

Original header: {'upgrade-insecure-requests': '1', 'user-agent':'Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) HeadlessChrome/69.0.3494.0 Safari/537.36', 'accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8'}
