使用 swapexactethfortokens 时 Web3py 事务被还原

Question

我正在使用以下 function 发起交易。 合约 = web3.eth.contract（地址=路由器地址，abi=PancakeABI）

nonce = web3.eth.get_transaction_count(sender_address)
amountIn = (web3.toWei(0.0001,'ether')) 
start = time.time()
print(web3.toWei('0.002','ether'))
toBuyBNBAmount = web3.toWei("0.0002", 'ether')
pancakeswap2_txn = contract.functions.swapExactETHForTokens(
0, # here setup the minimum destination token you want to have, you can do some math, or you can put a 0 if you don't want to care
[spend,contract_id],
sender_address,
(int(time.time()) + 1000000)
).buildTransaction({
'from': sender_address,
'value': toBuyBNBAmount,#This is the Token(BNB) amount you want to Swap from
'gas': 160000,
'gasPrice': web3.toWei('5', 'gwei'),
'nonce': nonce
})



 
signed_txn = web3.eth.account.sign_transaction(pancakeswap2_txn, private_key=private)
tx_token = web3.eth.send_raw_transaction(signed_txn.rawTransaction)
print(web3.toHex(tx_token))

但是每次我的交易被还原时： https://bscscan.com/tx/0x021ea258b937ba1575cdf5aed0f49fcad1143f2fc8b25eb8efffdc2347ca6729

Answer 1

我认为这个代码行是问题[spend,contract_id]你需要把[tokenA_address, tokenB_address]
