web3.eth.filter 相关

web3.eth.filter 这个主要是用来监听得,如下代码块所示，就是监听每个新块得信息

from web3 import Web3
import time
import json

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

def handle_event(event):
    jsonEventContents = json.loads(Web3.toJSON(event))
    print(jsonEventContents)

def log_loop(event_filter, poll_interval):
    while True:
        for event in event_filter.get_new_entries():
            handle_event(event)
        time.sleep(poll_interval)

def main():
    block_filter = web3.eth.filter("latest")
    log_loop(block_filter, 2)

if __name__ == '__main__':
    main()

如果用   “latest" ,"pengding"来监听，返回得hx值，如果按条件过滤，就会返回整个日志对象
