J'ai essayé de configurer l'utilisation du Chrome DevTools à l'aide de Sélénium 4 et Python. J'ai été en mesure de faire fonctionner localement (sans les async trucs), mais lorsque j'essaie d'utiliser le webdriver.À distance de mise en œuvre, il se bloque.
Voici un exemple à partir du Sélénium docs: https://www.selenium.dev/de/documentation/support_packages/chrome_devtools/
Ci-dessous comment j'ai essayé de l'exécuter.
import asyncio
from selenium import webdriver
import selenium.webdriver.common.devtools.v96 as devtools
async def geo_location_test():
try:
chrome_options = webdriver.ChromeOptions()
driver = webdriver.Remote(
command_executor='http://D5365900:4444/wd/hub',
options=chrome_options
)
async with driver.bidi_connection() as session:
cdp_session = session.session
await cdp_session.execute(devtools.emulation.set_geolocation_override(latitude=41.8781,
longitude=-87.6298,
accuracy=100))
driver.get("https://my-location.org/")
finally:
driver.quit()
async def main():
await geo_location_test()
if __name__ == "__main__":
asyncio.run(main())
Il fonctionne jusqu'à la ligne async with driver.bidi_connection() as session: (session est établie et le navigateur google Chrome s'ouvre). Mais la il se bloque avec la suite de trace.

Comme vous pouvez le voir, je suis en utilisant Python 3.10. J'ai aussi mis à jour le Sélénium liaisons 4.1.0 et suis en cours d'exécution de Sélénium 4.0.0 Hub/Nœud config pour automatiser Chrome 96.
Toutes les idées, ce qui est le problème ici? Suis-je la manipulation de l'asynchrone coroutines de façon incorrecte?
Toute aide est très appréciée!
Mise à jour Après avoir essayé de le faire fonctionner avec trio (comme suggéré dans Henry Ashton-Martyn du commentaire), j'obtiens l'erreur suivante.
Traceback (most recent call last):
