恐慌：索引越界 |坚固性 |松露

Question

我正在尝试使用松露框架在 ganache-cli 中部署以下智能合约。

// SPDX-License-Identifier: MIT
pragma solidity 0.8.13;

contract Sample {
    address[] public owners;
    constructor(address[] memory temp) {
        for(uint256 i=0; i<temp.length; i++) {
            owners[i] = temp[i];
        }
    }
}

但是我收到以下错误。

   Deploying 'Sample'
   ------------------
✖ Transaction submission failed with error -32000: 'VM Exception while processing transaction: revert'
 *** Deployment Failed ***

"Sample" hit a require or revert statement with the following reason given:
   * Panic: Index out of bounds


Exiting: Review successful transactions manually by checking the transaction hashes above on Etherscan.

帮我解决这个问题。

Answer 1

address[] public owners;

此行声明了包含 0 个项目的数组。

owners[i] = temp[i];

并且此行试图分配给数组中不存在的第 i 个项目。

解决方法：需要使用push()函数调整数组大小并设置新的项值。

for(uint256 i=0; i<temp.length; i++) {
    owners.push(temp[i]);
}
