Solidity 数据类型小结 分类 核心内容 关键特性 类型体系 分为值类型、引用类型、映射类型三大类 Solidity 是静态类型语言，变量类型编译时确定 值类型 包含布尔、整型（uint/int）、地址、定长字节数组、枚举、函数类型等 1. 赋值/传参时值拷贝，修改副本不影响原变量 2. 数据占用 ≤32 字节 3. 示例：uint a=10; uint b=a; b=20; → a 仍为 10 引用类型 包含数组、结构体、string/bytes（动态字节数组）、合约 1. 数据占用通常 >32 字节，支持引用传递减少拷贝开销 2. 必须显式指定数据位置（memory/storage/calldata） 3. 赋值规则： - 不同位置赋值 → 拷贝副本 - 相同位置赋值 → 创建引用（修改新变量会影响原变量） 数据位置（引用类型专属） 4 种位置（transient 不支持引用类型） storage 存储状态变量，永久保存在区块链，Gas 消耗最高 memory 函数内临时存储，函数执行后释放，Gas 中等 calldata 存储 external 函数参数，只读不可修改，Gas 消耗最低 transient 单次交易内有效，不支持引用类型定义 映射类型 键值对结构（mapping(KeyType => ValueType)） 1. 类似字典/哈希表，仅支持作为状态变量（storage） 2. 详细用法需结合后续数据结构章节学习 值类型 vs 引用类型 ...

准备： 以太坊智能合约开发基础: https://learnblockchain.cn/article/22542?course_id=93 IDE: Remix https://remix.ethereum.org/ MetaMask 钱包: https://metamask.io/zh-CN/download Solidity 合约长什么样？ 小结 合约基础结构 Solidity 合约是部署到区块链的最小单元，类似其他语言的class，核心由状态变量（存储合约数据）和合约函数（处理数据逻辑）组成。 编写合约需先通过pragma solidity声明编译器版本（如pragma solidity >=0.8.0;）。 核心组件解析 构造函数：用constructor声明，仅在合约部署时执行，用于初始化状态变量；若省略，编译器会自动生成默认构造函数。状态变量可在声明时直接初始化，未初始化则默认值为 0。 变量与函数可见性：共 4 种，public（内部/外部均可访问，状态变量自动生成 getter 函数）、external（仅外部可调用，内部调用需用this.func()）、internal（当前合约及派生合约可访问，默认可见性）、private（仅当前合约可访问）。注意：链上数据透明，private仅限制访问权限，无法隐藏数据。 特性 public external internal private 修饰函数 √ √ √ √ 修饰变量 √ √ √ 当前合约内可访问 √ √ √ 派生合约可访问 √ √ 外部访问 √ √ 特殊变量类型： constant常量：编译期确定值，不占用存储，仅支持值类型和字符串，赋值不可依赖链上/外部数据。 immutable不可变量：部署时（构造函数中）赋值，之后不可修改，不占用存储，适合存储合约创建者地址、关联合约地址等固定值。 函数定义规则 函数格式为function 函数名(参数类型 参数名) 可见性 状态可变性 returns(返回类型)，包含以下核心特性： 参数与返回值：参数声明与变量一致；返回值支持命名（可直接赋值）或仅指定类型，用return语句返回结果。 状态可变性修饰符： view视图函数：仅读取状态，外部调用无需 Gas，内部被修改状态的函数调用时需消耗 Gas。 pure纯函数：不读取、不修改状态，仅做计算逻辑。 payable：允许函数接收以太币，未声明则拒绝接收以太币。 状态修改逻辑：修改状态变量的函数需通过区块链交易调用，消耗 Gas 并经节点共识确认；仅读取状态的函数可直接在节点执行，无需上链。 合约的核心是状态转换 ...
