稳固性: address.send、address.transfer和address.call都不起作用。

Question

问题

每当我从javascript调用paytest函数(请参见下面的代码片段)时(请参见下面的代码片段)，我将收到下面发布的错误消息。无论我使用address.send、address.transfer还是address.call，matter.Nothing都不起作用。我在所有账户上都有大量的ETH测试。

我用安全帽做我当地的连锁店。

请帮帮我。我快疯了。

实心码

    contract DC is ERC1155, Ownable {
    
    function paytest (address receiver, uint256 amount) public payable{
            (bool success, bytes memory _data) = payable(receiver).call{value:amount}("");
             require (success, "transaction failed");
             data=_data;
    }

    event Log(string fun, address sender, uint value, bytes data);

    fallback() external payable {
        emit Log("fallback", msg.sender, msg.value, msg.data);
    }

    receive() external payable {
        emit Log("receive", msg.sender,msg.value, "");
        
    }

Javascript文件

   async function main () { // boiletplate function 
    
    
    const address = '0xDc64a140Aa3E981100a9becA4E685f962f0cF6C9'; // actual contract address
    const DC = await ethers.getContractFactory('DC');
    const dc = await DC.attach(address);
    
    const [owner, addr1, addr2] = await ethers.getSigners(); 
    await dc.connect(addr1).paytest(address,ethers.utils.parseEther("1.0"));

代码中有一个小语法错误。您不能像这样直接在函数中发送所需的ETH。您必须在另一个块中以"value“的名称发送它。因此，与其：

await dc.connect(addr1).paytest(address,ethers.utils.parseEther("1.0"));

尝尝这个,

await dc.connect(addr1).paytest(address,{ value: ethers.utils.parseEther("1.0")});

Update:我个人在输入ETH值时使用convertWithDecimal()函数的另一种方法。该函数自动处理BigNumber错误。

const isInt = (n: any) => {
  return n % 1 === 0;
};

const convertWithDecimal = (value: any, decimal: any) => {
  if (value > 0) {
    if (isInt(value)) {
      value = parseInt(value);
      value = BigNumber(value).multiply(decimal);
    } else {
      value = value * decimal;
      value = toFixed(value);
      value = parseInt(value.toString().split(".")[0]);
      value = toFixed(value);
      value = BigNumber(value);
    }
    return value.toString();
  } else {
    return 0;
  }
};

const toFixed = (x: any) => {
  if (Math.abs(x) < 1.0) {
    var e = parseInt(x.toString().split("e-")[1]);
    if (e) {
      x *= Math.pow(10, e - 1);
      x = "0." + new Array(e).join("0") + x.toString().substring(2);
    }
  } else {
    var e = parseInt(x.toString().split("+")[1]);
    if (e > 20) {
      e -= 20;
      x /= Math.pow(10, e);
      x += new Array(e + 1).join("0");
    }
  }
  return x;
};

只需将其粘贴到您的JS文件中，当输入ETH值时，将syntazx更改为以下内容。

await dc.connect(addr1).paytest(address,{ value: convertWithDecimal(1, 10**18});
