Ethereum 如何从交易凭证重新创建原始交易，以验证v、r、s签名？

我正在尝试验证以太坊交易

以下是我的步骤。
1.进行交易
2.使用eth.getTransaction（）获取事务
3.使用ethereumjs tx重新创建事务

但有时我无法验证交易

案例1：私有测试网上的简单发送以太事务

获取事务详细信息

为什么呢？ 如何正确地重新创建原始事务

或者是否有任何其他方式验证带有v、r、s签名的交易

---

提前感谢。

如果您使用的是web3js v1.0，您只需使用即可。他们文档中的示例：

web3.eth.accounts.recover({
    messageHash: '0x1da44b586eb0729ff70a73c326926f6ed5a25f5b056e7f47fbc6e58d86871655',
    v: '0x1c',
    r: '0xb91467e570a6466aa9e9876cbcd013baba02900b8979d43fe208a4a4f339f5fd',
    s: '0x6007e74cd82e037b800186422fc2da167c747ef045e5d18a5f5d4300f8e1a029'
})
> "0x2c7536E3605D9C16a7a3D7b1898e529396a65c23"

另一个选项是，您可以在使用Solidity的

ecrecover（）

的合同中调用

视图

函数

ecrecover（字节32哈希，uint8 v，字节32 r，字节32 s）返回（地址）：从椭圆曲线签名中恢复与公钥关联的地址，错误时返回零

例如：

function verify(bytes prefix, bytes32 msgHash, uint8 v, bytes32 r, bytes32 s) external pure returns(address) {
  bytes32 prefixedHash = keccak256(prefix, msgHash);
  return ecrecover(prefixedHash, v, r, s);
}

---

但是，您必须小心使用前缀。不同的客户端可能使用不同的前缀。例如，

geth

使用

prefix=“\x19Ethereum签名消息：\n32”对事务进行签名“

谢谢您的回复。在这种情况下，msgHash是什么？看起来hash和blockHash不是一个…而是你签名的消息的sha3散列。顺便说一句，你最初的方法也没有什么问题。我运行了您的签名发送并返回了正确的地址：>signed.getSenderAddress（）.toString（'hex'）；'0d6883a0e7071513c7d90a27bf2715bc71ecf107'。也许是因为你在你的对象中拼错了“nonce”？是的，你是对的！这是因为我的打字错误。谢谢
