目前，我使用以下python代码连接到web3
from web3 import Web3
# Fill in your infura API key here
infura_url = "https://mainnet.infura.io/v3/djsoiqowejojoajsdooqw"
web3 = Web3(Web3.HTTPProvider(infura_url))
我现在使用 AWS managedblockchain，它给了我这个凭证：
Node ID
nd-GFJL!JJDANSANJQWEQNDSA
Blockchain instance type
bc.t3.large
Availability zone
us-east-1f
WebSocket EndpointInfo
nd-ajdsojasdnqkebjb1k2jbj.wss.ethereum.managedblockchain.us-east-1.amazonaws.com
HTTP EndpointInfo
nd-zVfjoaisjodbqiwubjud.ethereum.managedblockchain.us-east-1.amazonaws.com
ARN
arn:aws:managedblockchain:us-east-1:871628371628:nodes/nd-JASDOIOWQEBJABKJA
如何使用这些信息通过 web3py 访问 web3？
