Question

I m 试图读到与UniswapV3号公司有关的待决交易,使用该代码作为同文。

address_router = "0x68b3465833fb72A70ecDF485E0e4C7bD8665Fc45"
with open("abiRouterUniswapV3.json", "r") as myFile:
data = myFile.read()
abiRouter = json.loads(data)

contractRouter = w3.eth.contract(address=address_router, abi=abiRouter)

block_filter = w3.eth.filter( pending )

def handle_event(event):
try:
    tx = w3.eth.getTransaction(event)
    tx_to = tx.to
except Exception:
    pass
else:
    if tx_to == "0x68b3465833fb72A70ecDF485E0e4C7bD8665Fc45": #filtering only UniswapV3 
        input_decoded = contractRouter.decode_function_input(tx.input)
        print("hash: ", tx.hash.hex())
        print(input_decoded)

然而,Im利用UniswapV3航道公司ABI制造合同路子,使解密成为可能。当功能是多功能时,它没有将数据编码在投入中。举例来说,当职能是多种调动时,它就产生了这一结果。

您可以看到数据为t decode

我的法典中有什么错误,或我所失踪的是什么? 我将真正赞赏你能够向我提供的任何帮助或指导。

因此,你指的是从数据中获取大麻。当你想获得数据编码时,你应当从一夫一妻或你需要检查接口的某个地方发现事件,并且你可以使用像这种(g)swap这样的事件合同。

tx_receipt = w3.eth.waitForTransactionReceipt(tx_hash)
pairContract = w3.eth.contract(address = pairAddress, abi = pairAbi)
swap = pairContract.events.Swap()
events = swap.processReceipt(tx_receipt, errors=DISCARD)
amount0_out = events[-1]["args"]["amount0Out"]
amount1_out = events[-1]["args"]["amount1Out"]
