Solidity
Web3 JS 中 Solidity 的 abi.encode() 函式的等價物是什麼?
我在 Solidity 中有一個函式,我想使用 Typescript 和 Web3 進行複制
function mint( address to, uint256[] memory ids, uint256 indexToMint ) public { require( registeredHashes[to][keccak256(abi.encode(to, ids))], "Hash not registered" ); ...
什麼是相當於行的 Web3js + Typescript
abi.encode(to, ids)
您可以使用
web3.eth.abi.encodeParameters
:const web3 = new Web3; web3.eth.abi.encodeParameters( ['address', 'uint256[]'], ['0x6b175474e89094c44da98b954eedeac495271d0f', [1, 2, 3]] );
結果是:
0x0000000000000000000000006b175474e89094c44da98b954eedeac495271d0f00000000000000000000000000000000000000000000000000000000000000400000000000000000000000000000000000000000000000000000000000000003000000000000000000000000000000000000000000000000000000000000000100000000000000000000000000000000000000000000000000000000000000020000000000000000000000000000000000000000000000000000000000000003
