有朋友知道具体是什么原因吗?谢谢您

看来还是你的data 有问题,你看下能你使用的参数是不是能解析出来,慢慢调

const { ethers } = require("ethers");

// 合约 ABI
const contractABI = [
  // 合约的 ABI
];

// 方法签名
const methodSignature = "YOUR_METHOD_NAME(uint256, address, ...)";
const methodID = ethers.utils.id(methodSignature).slice(0, 10);

// 检查 data 的前四个字节是否匹配方法签名
if (data.startsWith(methodID)) {
  console.log("Method ID matches");
} else {
  console.error("Method ID does not match");
}

// 解码参数
const iface = new ethers.utils.Interface(contractABI);
const decodedData = iface.decodeFunctionData(methodSignature, data);

console.log(decodedData);
