我一直在 Azure Blockchain Workbench 上构建投票应用程序。 我在上传智能合约文件时不断收到错误，提示构造函数和函数不存在。不过配置文件通过了检查。请帮忙解决错误。
这来自智能合约文件:
pragma solidity >= 0.4.0 <0.6.0;
contract Voting{
enum StateType{
Creation,
Voting,
BallotFinish
}
StateType public State;
mapping(bytes32 => uint256) public votesCount;
address public admin;
bytes32[] public candidatesList;
bytes32[] public voterList;
constructor(bytes32[] memory candidateNames,bytes32[] memory voterNames) public{
State = StateType.Creation;
admin = msg.sender;
candidatesList = candidateNames;
voterList = voterNames;
}
function totalVotesFor(bytes32 candidate) public view returns (uint256)
{
require(validCandidate(candidate));
return votesCount[candidate];
}
function voteForCandidate(bytes32 voter,bytes32 candidate) public {
if(admin == msg.sender)
{
revert();
}
if(State == StateType.Voting)
{
require(validVoter(voter));
require(validCandidate(candidate));
votesCount[candidate] += 1;
}
else
{
revert();
}
}
function validVoter(bytes32 voter) public view returns (bool) {
for(uint i=0;i<voterList.length;i++)
{
if(voterList[i]==voter)
return true;
}
return false;
}
function validCandidate(bytes32 candidate) public view returns (bool) {
for(uint i=0 ; i < candidatesList.length ; i++)
{
if(candidatesList[i]==candidate)
return true;
}
return false;
}
}
这是配置文件:

最佳答案
您的 sol 文件需要具有 json 文件中指定的合约构造函数。
我认为你需要将 byte32 更改为字符串并使用 StringUtil 进行字符串比较
