我做了一个存钱罐，我希望能够进行支票。但事实证明，我无法使用超过 15 个零进行付款。这个是正常的？
这是我注册支票的功能：
function setdebtor(address _address, uint _checkId, uint256 _amount) segurity public {
check[_checkId] = _amount;
debtor[_address] = true;
}
我的映射：
mapping(uint => uint256) check;
mapping(address => bool) debtor;
和我的支付功能：
function paycheck(uint _check) public {
require(debtor[msg.sender]);
msg.sender.transfer(check[_check]);
debtor[msg.sender] = false;
}
但是，如果我进行金额大于 15 个零的支票，我会收到以下错误：
transact to Hucha.setdebtor errored: Error encoding arguments: Error: invalid number value (arg="", coderType="uint256", value=30000000000000000, version=4.0.37)
>
那是 uint256 类型的限制？
这没有多大意义，因为在这个函数中，我引入了 18 个零的量，没有问题......
function enterFunds(uint amount) public payable {
require(msg.value == amount);
emit operations("Ingreso realizado de: ", amount);
}
所有代码：
pragma solidity ^0.5.11;
contract Hucha {
address owner;
mapping(address => bool) debtor;
mapping(uint => uint) check;
event operations(string msg, uint amount);
modifier segurity {
require(msg.sender == owner);
_;
}
constructor() public {
owner = msg.sender;
}
function getbalance() view public returns(uint) {
return address(this).balance;
}
function enterFunds(uint amount) public payable {
require(msg.value == amount);
emit operations("Ingreso realizado de: ", amount);
}
function extractFunds(uint amount) segurity public {
msg.sender.transfer(amount);
emit operations("Se han sacado: ", amount);
}
function kill() segurity public {
selfdestruct(msg.sender);
}
function paycheck(uint _check) public {
require(debtor[msg.sender]);
require(check[_check] != 0); // si no existe el cheque devolvera cero.
msg.sender.transfer(check[_check]);
debtor[msg.sender] = false;
}
function setdebtor(address _address, uint _checkId, uint256 _amount) segurity public {
check[_checkId] = _amount;
debtor[_address] = true;
}
}
