Code Snippet

import asyncio
from playwright.async_api import async_playwright, Route, Request


async def func(url):
    async with async_playwright() as p:
        _browser = await p.webkit.launch(proxy={"server": "socks5://127.0.0.1:10808"})
        _context = await _browser.new_context()
        page = await _context.new_page()

        async def _hook_request(route: Route, request: Request):
            new_headers = {
                **request.headers,
                'TEST': 'test123456789',
                'Cookie': 'AAAA=NBBBB; '
            }
            print(request.url)
            print(new_headers)
            await route.continue_(headers=new_headers)
            pass
        await page.route('*',_hook_request)
        await page.goto(url, wait_until='networkidle', timeout=5*60*1000)
        print(await page.inner_text('*'))
        await _context.close()
        await _browser.close()
        pass
    pass


async def main():
    await func('http://httpbin.org/get')
    pass


if __name__ == '__main__':
    asyncio.run(main())
    pass

Describe the bug

Execute the above code, the output is as follows:

http://httpbin.org/get
{'accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8', 'upgrade-insecure-requests': '1', 'user-agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/15.4 Safari/605.1.15', 'TEST': 'test123456789', 'Cookie': 'AAAA=NBBBB; '}
{
  "args": {}, 
  "headers": {
    "Accept": "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8", 
    "Accept-Encoding": "gzip, deflate",

  }, 
  "origin": "104.245.96.65", 
  "url": "http://httpbin.org/get"
}

Apparently the Hook request and then modifying the cookie fails.If I change my browser to Chromium it works as expected, but there are some other issues. By the way the same code works as expected under Windows.

Thanks Reply. The second object is output on line 23 print(await page.inner_text('*')) in the above code. The second object is the result returned by accessing http://httpbin.org/get

I have a similar issue. I use msw and playwright-msw which under the hood intercepts all requests using page.route. In my case, cookies are set in WebKit but in playwright intercepted requests don’t have cookies in headers even though I can see that WebKit browser included them (I can see it from devtools). In other browsers, cookies are properly included in intercepted requests but for WebKit they aren’t.

Can you please re-open this issue?
