deploy遇到问题，查了google也没解决

代码如下：
pragma solidity ^0.4.18;
contract Voting {
//xiaop14
//lih10
//luoh13
//wangjq15
//wangy17
//["xiaop","lih","luoh","wangjq","wangy"]
bytes32[] candidates = new bytes32[](5);
mapping(bytes32 => uint) candidatesVotingCount;

function Voting(bytes32[] _candidates) public {
for (uint i=0; i<_candidates.length; i++) {
candidates[i] = _candidates[i];
}
}

function isValidCandidate(bytes32 person) constant public returns (bool) {
for(uint i=0; i//bytes storage a = bytes(candidates[i]); //*****
if (candidates[i]==person) {

return true;
}
}

}

function VotingToPerson(bytes32 person) public {
assert(isValidCandidate(person)); //判断zhen jia真假
//require(isValidCandidate(person)); //功能同上
candidatesVotingCount[person] += 1;

}

function VotingTotalToPerson(bytes32 person) constant public returns (uint) {
require(isValidCandidate(person));
return candidatesVotingCount[person];
}
【deploy遇到问题，查了google也没解决】}
deploy后提示creation of Voting errored: Error encoding arguments: Error: invalid bytes32 value (arg="", type="string", value="https://www.it610.com/article/xiaop")
google后两种解决方案
1、将bytes32转码成16进制如"xiaop"转成"0x7869616f70"，但是又遇到
creation of Voting errored: Error encoding arguments: Error: hex string cannot be odd-length //字符串长度不一致问题，只能输入同样长度的16进制数。deploy成功
2、将bytes32用string代替，没有去实现，继续上课中，有时间再来尝试
