稳定性:从已部署的合约调用函数恢复

Question

我试图调用getNames()函数对反向记录ens查找合约在这里，但它是恢复。这是我的代码:

pragma solidity ^0.8.0; pragma experimental ABIEncoderV2;
contract ENStest {
/* ENS Reverse Lookup
Ropsten: 0x72c33B247e62d0f1927E8d325d0358b8f9971C68
Rinkeby: 0x196eC7109e127A353B709a20da25052617295F6f
Goerli: 0x333Fc8f550043f239a2CF79aEd5e9cF4A20Eb41e
Mainnet: 0x3671aE578E63FdF66ad4F3E12CC0c0d71Ac7510C
*/
address public ENSReverseLookupContractAddr = address(0x196eC7109e127A353B709a20da25052617295F6f); // Rinkeby

function addrToENS(address addr) public view returns(string[] memory) {
ReverseRecords ens = ReverseRecords(ENSReverseLookupContractAddr);
return ens.getNames([addr]);
}
}

// ENS Reverse Lookup Remote Contract
abstract contract ReverseRecords {
function getNames(address[] calldata addresses) external view virtual returns (string[] memory r);
}

有谁知道我在这里做错了什么吗?

我正在将固定长度的数组转换为动态大小的数组。(h/t https://ethereum.stackexchange.com/a/103894/25695)

修改后的代码:

function addrToENS(address addr) public view returns(string[] memory) {
ReverseRecords ens = ReverseRecords(ENSReverseLookupContractAddr);
address[] memory t = new address[](1);
t[0] = addr;
return ens.getNames(t);
}
