abi的编码和解码过程：

1、abi.encode

2、abi.decode

    // SPDX-License-Identifier: MIT
    pragma solidity ^0.8.30;
    
    contract abiDecode {
    
        struct MyStruct{
            string name;
            uint[2] nums;
        }
    
        function encode(uint x, address addr, uint[] calldata arr, MyStruct calldata myStruct) external pure returns(bytes memory){
            return abi.encode(x,addr,arr,myStruct);
        }
    
        function decode(bytes calldata data) external pure returns(
            uint x, address addr, uint[] memory arr, MyStruct memory myStruct
        ){
            (x,addr,arr,myStruct) = abi.decode(data, (uint, address, uint[], MyStruct));
        }
    }
