eth | struct 和 bytes 怎么交互

发表于 分类于 ， ， ， ， ， ， ， ， ， Valine：

这里用 lifeform | 合约 来做案例。

具体案例是 0xd7d75807d4c92bdf2f69e549d9be20b31e3c576e45137d1de201e9b696ad29dc

struct MintRule {
    address mintRule;
    uint256 udIndex;
    address stakeErc20;
    uint256 stakeErc20Amount;
    address costErc20;
    uint256 costErc20Amount;
    uint256 limitTimes;
    uint256 mintType;
    bytes32 signCode;
    bytes wlSignature;    //wlSignature
}

合约交互如下

使用 python 交互如下
