je un tel code (Python 2.5, GAE serveur dev):Python: attrapant exception particulière
try:
yt_service.UpgradeToSessionToken() // this line produces TokenUpgradeFailed
except gdata.service.TokenUpgradeFailed:
return HttpResponseRedirect(auth_sub_url()) # this line will never be executed (why?)
except Exception, exc:
return HttpResponseRedirect(auth_sub_url()) # instead this line is executed (why?)
Je me suis donc point d'arrêt à la dernière ligne et sous débogueur je vois:
"exc" TokenUpgradeFailed: {'status': 403, 'body': 'html stripped', 'reason': 'Non 200 response on upgrade'}
"type(exc)" type: <class 'gdata.service.TokenUpgradeFailed'>
"exc is gdata.service.TokenUpgradeFailed" bool: False
"exc.__class__" type: <class 'gdata.service.TokenUpgradeFailed'>
"isinstance(exc, gdata.service.TokenUpgradeFailed)" bool: False
"exc.__class__.__name__" str: TokenUpgradeFailed
Ce que je manqué dans la gestion des exceptions python? Pourquoi isinstance (exc, gdata.service.TokenUpgradeFailed) est faux?
