从 sendSignedTransaction 获取还原原因

Question

我正在运行一个 Hyperledger Besu 私有链，并从 Express 服务器发出 sendSignedTransaction 调用。

        try {
            let tx = {
                from: fromAccount,
                to: this.contract.options.address,
                gas: 2000000,
                gasPrice: "0",
                value: 0,
                data: await this.contract.methods
                    .method().encodeABI()
            };
    
            console.log(tx);
            console.log("signing transaction");
            let signedTx = await this.web3.eth.accounts.signTransaction(tx, privateKey);
            console.log("transaction signed");
            let result = await this.web3.eth.sendSignedTransaction(signedTx.rawTransaction)
            console.log(result);
        }
        catch (e) {
            console.log(e);
        }

交易正在还原并被捕获，但我不确定如何获取还原原因。我已经尝试设置contract.handleRevert 以及来自搜索引擎的其他解决方案，但所有其他解决方案都假定您从前端使用sendTransaction、call 或send。根据 web3.js 文档，handleRevert 不适用于 sendSignedTransaction (https://web3js.readthedocs.io/en/v1.2.11/web3-eth.html#handlerevert)，并且错误以一个长字符串形式返回：

  }
}

我还尝试在 revertReason 十六进制代码上运行十六进制到 ascii 转换器，但该值不可读。

我希望能够获得 sendSignedTransaction 调用的恢复原因。

Answer 1

您可以使用web3.utils.hexToAscii() 解码revertReason。

const reason = web3.utils.hexToAscii('0x08c379a0000000000000000000000000000000000000000000000000000000000000002000000000000000000000000000000000000000000000000000000000000000204552433737373a2073656e6420746f20746865207a65726f2061646472657373');

注意：前两个字符看起来像 UTF BOM，但 hexToUtf8() 无法解码字符串（字符串的其余部分实际上是 ASCII，而不是 UTF）。
