部署智能合约时获取 "undefined" 的参数数量无效

Question

我正在尝试在 testRPC 上部署我的第一个投票合约，下面是我的代码。出于某种原因，当我开始部署时它在抱怨。

错误似乎来自 arguments 参数。我尝试传递一个空数组，它说“Got 0 expected 1!”。我尝试只传递一个名称，它说“value.forEach”不是一个函数。

Web3 = require('web3')
web3 = new Web3(new Web3.providers.HttpProvider("http://localhost:8545"));
sourceCode = fs.readFileSync('Voting.sol').toString()
solc = require('solc')
compiledCode = solc.compile(sourceCode)
abiDefinition = JSON.parse(compiledCode.contracts[':Voting'].interface)
VotingContract = new web3.eth.Contract(abiDefinition)
byteCode = compiledCode.contracts[':Voting'].bytecode

VotingContract.deploy({
    data: byteCode, 
    arguments:['Joseph','Sean','Matthew']
}).send({
    from: '0x00D1AE0A6fC13B9ecdefA118B94cF95ac16D4ab0', 
    gas: 4700000
})
.on('error', function(error) {
    console.log(error);
}
.then(function(newContractInstance) {
    console.log(newContractInstance.options.address)
}

Answer 1

为需要构造函数参数的合约尝试类似的方法

var bytecodeWithParam = MyContract.new.getData(
    param1,
    param2,
    { data: compiledByteCode });

您粘贴到 "Byte Code" 字段中的就是这个 bytecodeWithParam。仔细看的话，最后会看到param1和param2 32字节打包。

另一个例子

var MyContract = web3.eth.contract(abiArray);

// instantiate by address
var contractInstance = MyContract.at(address);

// deploy new contract
var contractInstance = MyContract.new([constructorParam1] [, constructorParam2], {data: '0x12345...', from: myAccount, gas: 1000000});

// Get the data to deploy the contract manually
var contractData = MyContract.new.getData([constructorParam1] [, constructorParam2], {data: '0x12345...'});
// contractData = '0x12345643213456000000000023434234'

Answer 2

在迁移中，将您的参数添加到部署程序中。

// Deploy a single contract with constructor arguments
deployer.deploy(A, arg1, arg2, ...);

其中 A 是您的智能合约，arg1、arg2 等是参数

文档中提到了这一点：https://www.trufflesuite.com/docs/truffle/getting-started/running-migrations#deployer-deploy-contract-args-options-
