我已经使用mist和geth在私人网络上部署了我的智能合约。
现在的困惑是:我如何通过Web3.js与智能合约互动。
这是我的剧本:
if (typeof web3 !== 'undefined') {
web3 = new Web3(web3.currentProvider);
} else {
// set the provider you want from Web3.providers
web3 = new Web3(new Web3.providers.HttpProvider("http://localhost:8545"));
}
web3.eth.defaultAccount = web3.eth.accounts[0];
var CoursetroContract = web3.eth.contract(YOUR ABI);
var Coursetro = CoursetroContract.at('PASTE CONTRACT ADDRESS HERE');
console.log(Coursetro);
当我尝试以下命令时:
> web3.providers
{
HttpProvider: function(host, timeout, user, password),
IpcProvider: function(path, net)
}
答案 0 :(得分:3)
设置infura后,您可以使用他们返回给您的门户网址网址来创建您的提供商。只需编辑您的脚本,如下所示:
if (typeof web3 !== 'undefined') {
web3 = new Web3(web3.currentProvider);
} else {
// set the provider you want from Web3.providers
web3 = new Web3(new Web3.providers.HttpProvider(<your infura.io url here>));
}
web3.eth.defaultAccount = web3.eth.accounts[0];
var CoursetroContract = web3.eth.contract(YOUR ABI);
var Coursetro = CoursetroContract.at('PASTE CONTRACT ADDRESS HERE');
console.log(Coursetro);
