Notes

2024.09.23

學習內容:

  • setup Foundary 的运行环境
  • 使用mkdir 命令建立 co—learning的文件夹
  • 使用forge init命令初始化
  • 使用 forge compile 编译 HelloWeb3.sol
  • 新开窗口用anvil创建一条本机链
  • 使用forge create部署HelloWeb3.sol合约

结果如下： [⠃] Compiling... No files changed, compilation skipped Deployer: 0xf39Fd6e51aad88F6F4ce6aB8827279cffFb92266 Deployed to: 0x5FbDB2315678afecb367f032d93F642f64180aa3 Transaction hash: 0x957fd94ac366ec5eef8c849dae9993b04b03c456cd61fd116621b44138bdf743

  • cast call 0x5FbDB2315678afecb367f032d93F642f64180aa3 "_string()" --rpc-url http://127.0.0.1:8545 得到_string的字节码， decode该字节码得到 “Hello，World” 字符串

  • Today's work is try to use script in Foundary to deploy more smart contracts. script is like this:
  • // SPDX-License-Identifier: MIT pragma solidity ^0.8.0;

import "forge-std/Script.sol"; import "../src/ValueTypes.sol"; import "../src/Function.sol"; import "../src/DataStorage.sol"; import "../src/Return.sol";

contract DeployScript is Script { function run() public {

    uint256 deployerPrivateKey = 0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80;
    vm.startBroadcast(deployerPrivateKey);

    // Deploy ValueTypes
    ValueTypes valueTypes = new ValueTypes();
    console.log("ValueTypes deployed to:", address(valueTypes));

    // Deploy Return
    Return return1 = new Return( );
    console.log("Return deployed to:", address(return1));

    FunctionTypes function1 = new FunctionTypes( );
    console.log("FunctionTypes deployed to:", address(function1));
    
    DataStorage dataStorage = new DataStorage( );
    console.log("DataStorage deployed to:", address(dataStorage));
    
    vm.stopBroadcast();
}

}

  • output : ValueTypes deployed to: 0x5FbDB2315678afecb367f032d93F642f64180aa3 Return deployed to: 0xe7f1725E7734CE288F8367e1Bb143E90bb3F0512 FunctionTypes deployed to: 0x9fE46736679d2D9a65F0992F2272dE9f3c7fa6e0 DataStorage deployed to: 0xCf7Ed3AccA5a467e9e704C703E8D87F634fB0Fc9
  • to be continued: test the functions in each contract. not finished today ,try to use script to test them one by one
