solidity - 如何在 Polygon 网络中解码智能合约的函数名称？

Question

我已经部署了合同（不是我的），没有提供 abi。

交易中使用的输入数据：

0xd1700e6c0000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000020000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000

有人可以帮忙，如何直接从 web3 调用这个函数？或者如何找出它的名字。据我了解，当您调用合约函数时，您会写：contract.methods.func().send(). 但是如果我只有methodId，如何调用/发送函数？

Answer 1

您可以在字段中创建包含函数选择器（以及函数参数）的原始交易data，对其进行签名，然后将其发送给您的节点提供商以将其广播到网络。

// the sender private key needs to be added to web3 `accounts.wallet`
// see the blue "note" card in the docs for more details

await web3.eth.sendTransaction({
    from: senderAddress,
    to: contractAddress,
    data: "0xd1700e6c..."
});
