ValueError：int字符串太大而无法转换Infura

问题描述

早上好， 在Flask项目中尝试通过web3从Infura获取以太坊余额时遇到错误。这是我得到的错误：

Traceback (most recent call last):
  File "app.py",line 13,in <module>
    from web3 import Web3

ValueError: int string too large to convert

这是我的代码。我相信一切正常...而且我认为这与Web3 HTTP Provider有关。 （不包括隐私问题的真实网址）

infura_url = "https://ropsten.infura.io/v3/______________________"
infura_secret = "___________"
ropsten_url = "https://ropsten.etherscan.io/address/________________"
test_address = "___________"

app = Flask(__name__)
app.secret_key = os.environ.get("SECRET_KEY") or os.urandom(24)


api = Api(app) 
web3 = Web3(Web3.HTTPProvider(ropsten_url))
balance = web3.eth.getBalance(test_address)
int_balance = web3.fromWei(balance,"ether")
print("Tu balance es de ",web3.fromWei(balance,"ether"))
