Blockchain 开放式齐柏林飞艇+;Truffle Ethereum Crowdsale buyTokens()函数的预付成本

我已确保在startTime之后和endTime之前调用该函数,并且每次在迁移契约之前都会更新2_deploy_contracts.js中的startTime。我这样做是为了尽可能少地依赖于调试此代码。我还要确保我发送的Wei少于cap。“c”是我使用deployed()函数得到的已部署契约。感谢您的帮助,干杯 您没有正确发送
值。您需要使用web3.utils.toWei(0.00000000000001,'ether')
简化版本:
pragma solidity ^0.4.18;
contract Test {
uint256 public balance;
function somePayable() public payable {
balance = msg.value;
