在钱包上支持ERC1155，只有账户地址的情况下没办法获取该地址所持有的token id，

获取token余额必须要知道account和tokneid，所以先要知道该账号有的tokenid

function balanceOf(address account, uint256 id) public view override returns (uint256) {
        require(account != address(0), "ERC1155: balance query for the zero address");
        return _balances[id][account];
    }

存储结构为mapping，没有数组，无法通过遍历获取

// Mapping from token ID to account balances
    mapping (uint256 => mapping(address => uint256)) private _balances;

有什么办法可以显示一个账号下的所有ERC1155 token
