[英]How to fix invalid address Error? Web3 JS with MetaMask
I deployed my contract to Goerli test net.我将合约部署到 Goerli 测试网。 Deploying was successful.部署成功。 And I tested it in Remix.我在 Remix 中对其进行了测试。
Contract code:合约代码:
pragma solidity ^0.5.0;
contract Test{
string private str;
constructor() public {
str = " ";
}
function getStr() public view returns(string memory _str){
_str = str;
}
function setStr(string memory _str) public{
str = _str;
}
}
Then I tried to make a web interface using web3 and MetaMask.然后我尝试使用 web3 和 MetaMask 制作一个 web 接口。
<script>
ethereum.enable()
var abi = [
{
"constant": false,
"inputs": [
{
"internalType": "string",
"name": "_str",
"type": "string"
}
],
"name": "setStr",
"outputs": [],
"payable": false,
"stateMutability": "nonpayable",
"type": "function"
},
{
"inputs": [],
"payable": false,
"stateMutability": "nonpayable",
"type": "constructor"
},
{
"constant": true,
"inputs": [],
"name": "getStr",
"outputs": [
{
"internalType": "string",
"name": "_str",
"type": "string"
}
],
"payable": false,
"stateMutability": "view",
"type": "function"
}
];
var address = 0x4316d047388e61EBC3Ed34DFf4cEE215840decDa;
var myContract = web3.eth.contract(abi);
var TestC = myContract.at(address);
console.log(TestC);
var x = TestC.getStr();
</script>
And when I ran it, it returned:当我运行它时,它返回:
Uncaught Error: invalid address未捕获的错误:地址无效

What I need to do?我需要做什么?
Your variable address
should be a hex string, not a literal hex number - even though it is eventually turned into a number by the ethereum node.你的变量address
应该是一个十六进制字符串,而不是一个十六进制数字——即使它最终被以太坊节点变成了一个数字。
Try this instead:试试这个:
var address = '0x4316d047388e61EBC3Ed34DFf4cEE215840decDa';
