Tengo una cuenta de Infura y tengo el siguiente código:
...
web3 = Web3(HTTPProvider("https://ropsten.infura.io/mytoken") )
web3_pending_filter = web3.eth.filter('pending')
...
cuando se web3_pending_filter = web3.eth.filter('pending')ejecuta la línea, aparece el error:
solicitudes.excepciones.HTTPError: 405 Error del cliente: método no permitido para la URL: https://ropsten.infura.io/mytoken
¿Cómo puedo solucionar este problema?
Infura no admite filtros.
