node.js - 无需元掩码即可写入以太坊

Question

我正在尝试在不使用元掩码的情况下将一些数据写入以太坊 Rinkeby 测试网络，但是在调用该方法时我收到以下错误，但我的参数计数是正确的

UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 246): Error: Invalid number of arguments to Solidity function

Node 代码

var Web3        = require('web3')
var contract    = require("truffle-contract")
var quickBooks    = require('../build/contracts/quickBooks.json')

Web3.providers.HttpProvider.prototype.sendAsync = Web3.providers.HttpProvider.prototype.send;

var provider    = new Web3.providers.HttpProvider("https://rinkeby.infura.io/v3/KEY")
var quickBooksContract = contract(quickBooks);
quickBooksContract.setProvider(provider);
    

var writeToEthereum = async function(_json){
    //console.log(_json)
    var instance = await quickBooksContract.at('ADDRESS')
    var result = await instance.write.call(_json,_json.txhash,_json.createdt,"1",_json.write_set[0].set,{
from : "ADDRESS"
})
    console.log(result);
}

坚固性

pragma experimental ABIEncoderV2;

contract quickBooks{

    struct Tx{
        string txId;
        string timeStamp;
        string blockHash;
        string payLoad;
        string json;
    }
    
    mapping(string => Tx) private data;

    function write(string _json,string _txId,string _timeStamp,string _blockHash,string _payLoad) public returns(bool success){
        data[_txId] = Tx(_txId,_timeStamp,_blockHash,_payLoad,_json);
        return true;
    }

    function read(string _txId)public returns(Tx){
        return data[_txId];
    } 
}

Answer 1

您的call合约函数是错误的，你应该在函数名后面传递参数给函数。您这样做的方式是在 call() 的位置传递参数。选项。

await instance.write(<params here>).call();
