foundry系列

foundry系列工具介绍，及常用命令

foundry

foundry系列的工具，主要包含三大组件，分别对应不同的功能，下面会每个组件依次试用。

• forge：主要用来开发、编译、部署合约。
• cast：执行以太坊 RPC 调用的命令行工具
• anvil：本地模拟节点环境，类似于ganache-cli的功能。

forge工具

• 初始化

  forge init

• 安装依赖环境

  forge b

• 生成合约code到指定目录

  forge inspect ScoreDemo bytecode -o ./contract_code

目录中的bytecode为需要部署合约的值

cast工具

• 获取当前区块高度

cast block -r http://localhost:8545

• 获取指定区块信息

cast block -r http://localhost:8545 {区块高度}

• 获取账户余额

cast balance -r http://localhost:8545 {钱包地址}

• 获取账户nonce

cast nonce -r http://localhost:8545 {钱包地址}

• 获取交易信息

cast tx -r http://localhost:8545 {交易hash}
# 等价于 getTransactionByHash

• 获取交易收据信息

cast receipt -r http://localhost:8545 {交易hash}
# 等价于 getTransactionReceipt

• call function

cast call -r http://localhost:8545 {合约地址} "函数名称(函数入参类型)(返回参数类型)" {入参参数} 

# eg:
cast call -r http://localhost:8545 0x27EddE8d0dF786996E5e389AcbdfE804ba9eaDb6 "getNumber()"
cast call -r http://localhost:8545 0x27EddE8d0dF786996E5e389AcbdfE804ba9eaDb6 "getNumber(uint256)(uint256)" 10
cast call -r http://localhost:8545 0xca5703d000BD3632169C21F4461Ad7E6f9F1a178 "getAll()(uint256[],string)"

------------
cast call -r http://localhost:8545 {合约地址} {method code} {编码后的input data}
# eg:
cast call -r http://localhost:8545 0x27EddE8d0dF786996E5e389AcbdfE804ba9eaDb6 0xf2c9ecd8

# eg:
cast send -r http://localhost:8545 0x27EddE8d0dF786996E5e389AcbdfE804ba9eaDb6 0x845e38e40000000000000000000000000000000000000000000000000000000000000064 --private-key 97dc393924f6d82795f4caf56a79b88ff4df036b04db076f2d254f6bfe0ea869 --legacy --async
