30 web3.py 异步
async def hello(i): w3 = Web3( Web3.AsyncHTTPProvider(endpoint_uri), modules={'eth': (AsyncEth,), 'net': (AsyncNet,)} ) a= await w3.eth.get_balance(i) print(a)
if name == "main": for i in di: asyncio.run(hello(i)) 出错显示bject function can't be used in 'await' expression 请问web3.py的异步应该怎么写

这样写。就少了，初始化时候的，middlewares=[]
import asyncio
import web3
from web3 import Web3
from web3.eth import AsyncEth
url = "http://127.0.0.1:8080"
async def GetNumber(w3):
n = await w3.eth.get_block_number()
print(n)
if __name__ == '__main__':
w3 = Web3(web3.AsyncHTTPProvider(url),
modules={'eth': (AsyncEth,)},
middlewares=[]
)
asyncio.run(GetNumber(w3))
