[email protected] 在依据abi创建智能合约的时候报错 TypeError: web3.eth.contract is not a function

前面的代码不变

var web3 = new Web3(new Web3.providers.HttpProvider("Http://localhost:8545"));
var abi = JSON.parse('[{"constant":true,"inputs":[{"name":"candidate","type":"bytes32"}],"name":"totalVotesFor","outputs":[{"name":"","type":"uint8"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[{"name":"candidate","type":"bytes32"}],"name":"validCandidate","outputs":[{"name":"","type":"bool"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[{"name":"","type":"bytes32"}],"name":"votesReceived","outputs":[{"name":"","type":"uint8"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[{"name":"","type":"uint256"}],"name":"candidateList","outputs":[{"name":"","type":"bytes32"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":false,"inputs":[{"name":"candidate","type":"bytes32"}],"name":"voteForCandidate","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"inputs":[{"name":"candidateNames","type":"bytes32[]"}],"payable":false,"stateMutability":"nonpayable","type":"constructor"}]');
var contractAddr = "0x3577f4d4902f4766753056468bd08ef68df6c623";
var VotingContract = new web3.eth.Contract(abi); 

先前的代码

var VotingContract = web3.eth.contract(abi);

 变化

• 多了一个new
• Contract首字母大写

修改为

var VotingContract = new web3.eth.Contract(abi);
