NodeJS合约部署

安装依赖 注意版本

npm install solc@0.4.18
npm install web3@^0.20.1
npm install ethereumjs-tx@^1.3.7

部署脚本

var Web3 = require('web3');
var Tx = require('ethereumjs-tx');
var solc = require('solc');
var fs = require('fs');

//init
if (typeof web3 !== 'undefined') {
    web3 = new Web3(web3.currentProvider);
} else {
    web3 = new Web3(new Web3.providers.HttpProvider("https://ropsten.infura.io/v3/1b8...b0"));
}
var fromAddr = '0x97...5B7';
var count = web3.eth.getTransactionCount(fromAddr);
var gasPrice = web3.eth.gasPrice;
var gasLimit = 3000000;
var privateKey = new Buffer.from('bb07...ed3c', 'hex');

//编译合约，获得bytecode
var source = fs.readFileSync("./test.sol", "utf8");
var compilied = solc.compile(source, 1);
var bytecode = compilied.contracts[':CallMeChallenge'].bytecode;

//要打包的交易信息
var rawTx = {
    'from': fromAddr,
    'nonce': web3.toHex(count),
    'gasPrice': web3.toHex(gasPrice),
    'gasLimit': web3.toHex(gasLimit),
    'value': '0x0',
    'data': '0x'+bytecode
};
var tx = new Tx(rawTx);
tx.sign(privateKey);
var serializedTx = tx.serialize();
var hashTx = web3.eth.sendRawTransaction('0x'+serializedTx.toString('hex'));
console.log('txHash: ' + hashTx);

var makeTx;
while (true) {
    makeTx = web3.eth.getTransaction(hashTx);
    if (makeTx["blockNumber"] !== null) {
        var receipt = web3.eth.getTransactionReceipt(hashTx);
        console.log("address: " + receipt["contractAddress"]);
        break;
    }
}
