我尝试了很多方法（实际上是所有方法），但仍然无法在 web3js 上获得恢复原因。我的 web3js 版本是 1.9.0，我有一个简单的 solidity 合约，它像这样投票：
function addVote(string memory voteName, string memory candidate, address addr) public returns(string memory){
require(candidateVote[voteName].length > 0, "Vote does not exist.");
// require(voteCount[voteName][candidate] == 0, "You have already voted for this candidate.");
require(!voters[voteName][addr], "Address has already voted!");
voteCount[voteName][candidate]++;
// voteCount[address][voteName][candidate]++
voters[voteName][addr] = true;
return "Vote successful casted!";
}
如您所见，我有 3 个要求，这是我在 nodejs 中的 web3js 调用：
export function addVote(web3:any, contract:any, abi: any,contractAddress:any,voteName:string, candidate:any, fromAccount:any){
return new Promise((resolve, reject) => {
contract.methods.addVote(voteName, candidate, fromAccount).send({from:fromAccount,gas:3000000})
.on('confirmation', function(confirmationNumber, receipt){
if(receipt.status){
resolve(receipt)
}else{
reject(receipt)
}
}).on('error', function(error, receipt) {
reject(error)
})
})
}
这是输出：
E:\Docker-project\dvote\node_modules\web3-utils\lib\index.js:49
error = new Error(error);

我必须提到我使用并设置了 web3.eth.handleRevert = true，没有任何反应！我还在 trxhash 上使用了 getTransactionReceipt，我希望该对象可能包含恢复原因，但它什么都没有。如果你能帮助我，我将不胜感激。
