将ETH发送到任意用户（Slither警告）

Question

我如何通过以下方法解决有关低级别调用的Slither警告：

 // A proposer calls function and if address has an allowance, recieves ETH in return.
    function getPayout(address payable addressOfProposer)
        public
        returns (bool)
    {
        // Get the available allowance first amd store in uint256.
        uint256 allowanceAvailable = _payoutTotals[addressOfProposer];
        require(allowanceAvailable > 0, "You do not have any funds available.");

        _decreasePayout(addressOfProposer, allowanceAvailable);

        (bool sent, ) = addressOfProposer.call{value: allowanceAvailable}("");
        require(sent, "Failed to send ether");

     // console.log("transfer success");
        emit Withdraw(addressOfProposer, allowanceAvailable);
        return true;
    }

Answer 1

使用// Slither-disable-next-line detector_name：

// A proposer calls function and if address has an allowance, recieves ETH in return.
    function getPayout(address payable addressOfProposer)
        public
        returns (bool)
    {
        // Get the available allowance first amd store in uint256.
        uint256 allowanceAvailable = _payoutTotals[addressOfProposer];
        require(allowanceAvailable > 0, "You do not have any funds available.");

        _decreasePayout(addressOfProposer, allowanceAvailable);

        //slither-disable-next-line unchecked-lowlevel
        (bool sent, ) = addressOfProposer.call{value: allowanceAvailable}("");
        require(sent, "Failed to send ether");

     // console.log("transfer success");
        emit Withdraw(addressOfProposer, allowanceAvailable);
        return true;
    }

有趣的是，它给出了未检查的低级呼叫警告，但是，鉴于它似乎确实已被检查。
