I want to get Page Source by the following code ,I wonder is it enough to detect all the network erroneous cases with the following code ?
@
if (reply.error()!= QNetworkReply.NoError):
print('11111111', reply.errorString())
return
content=reply.readAll().data()
if content==b'':
print('---------', 'cannot find any resource !')
return@

it's enough if you don't care about the specific type of the error...
But a reply is either successful or not. Qt delivers you error types if it recognizes them, if not it still knows that a error happened and returns QNetworkReply::UnknownNetworkError.
