我有两个问题目前无法解决。
1. 我想让浏览器保持运行状态,这样我只需要使用 pyppeteer.launcher.connect()
函数重新连接,但即使我没有调用 pyppeteer.browser.Browser.close()
,它似乎也会立即关闭。
test01.py:
import asyncio
from pyppeteer import launch, connect
async def fetch():
browser = await launch(
headless=False,
args=['--no-sandbox']
)
print(f'Endpoint: {browser.wsEndpoint}')
await browser.disconnect()
loop = asyncio.get_event_loop()
loop.run_until_complete(fetch())
$ python test01.py
Endpoint: ws://127.0.0.1:51757/devtools/browser/00e917a9-c031-499a-a8ee-ca4090ebd3fe
$ curl -i -N -H "Connection: Upgrade" -H "Upgrade: websocket" http://127.0.0.1:51757
curl: (7) Failed to connect to 127.0.0.1 port 51757: Connection refused
2. 如何创建CDP会话。以下代码应该打开另一个浏览器窗口,但实际上它没有按照预期工作:
test02.py
import asyncio
import time
from pyppeteer import launch, connect
async def fetch():
browser = await launch(
headless=False,
args=['--no-sandbox']
)
page = await browser.newPage()
cdp = await page.target.createCDPSession()
await cdp.send('Target.createBrowserContext')
time.sleep(5)
await browser.disconnect()
loop = asyncio.get_event_loop()
loop.run_until_complete(fetch())
$ python test02.py
Future exception was never retrieved
future: <Future finished exception=NetworkError('Protocol error Target.sendMessageToTarget: Target closed.',)>
pyppeteer.errors.NetworkError: Protocol error Target.sendMessageToTarget: Target closed.
