如何將純文字字元串變數轉換為 bytes32 變數?以及如何在轉換後將 bytes32 儲存在一個變數中?
pragma solidity ^0.4.25; contract Purchase { address public sellerAddress; constructor (address _sellerAddress) { sellerAddress = _sellerAddress; } } contract Buyer is Purchase { address public buyerAddress; string pass; bytes32 hashpass; modifier onlyBuyer() { require(msg.sender == buyerAddress); _; } constructor(string _pass) { buyerAddress = msg.sender; pass = _pass; } function stringToBytes32(string pass) returns (bytes32 hashpass) { hashpass = bytes32(pass); } function generateHashPass() public { } }
如果要將字元串轉換為 bytes32,可以使用這篇文章中描述的方法:如何將字元串轉換為 bytes32?
但是,您似乎正在嘗試對字元串進行雜湊處理,這可以使用諸如
keccak256
.hashpass = keccak256(pass);
