使用 python 在 Binance 智能链上出现 Web3 ExtraDataLength 错误

Question

我试图提取特定区块上发生的交易，但我被困在这里：

from web3 import Web3

bsc = "https://bsc-dataseed.binance.org/"
web3 = Web3(Web3.HTTPProvider(bsc))

block = web3.eth.get_block('latest')

web3.exceptions.ExtraDataLengthError: The field extraData is 97 bytes, but should be 32. It is quite likely that you are connected to a POA chain. Refer to http://web3py.readthedocs.io/en/stable/middleware.html#geth-style-proof-of-authority for more details.

我想获取某个钱包地址涉及的交易，但我不知道为什么 web3 不允许我从 bsc 节点提取该交易。

Answer 1

from web3 import Web3
from web3.middleware import geth_poa_middleware

web3 = Web3(Web3.HTTPProvider('127.0.0.1:100500'))
web3.middleware_onion.inject(geth_poa_middleware, layer=0)
