前言
在进行 Aptos 开发前,第一步是搭建本地开发环境,并验证工具链是否配置正确。最直接的方式,是通过编写并运行一个简单的 Move 程序,实现链上版本的 “Hello World”。本教程将以最小化的步骤,引导你完成 Aptos 开发环境的初始化与基础模块的部署,确保你具备开始构建更复杂应用的基础能力。

Aptos环境搭建
首先,在开始这篇文章之前你需要搭建好aptos-cli, 可以参考https://aptos.dev/en/build/cli
我们使用的mac系统,直接使用brew安装,
brew update
brew install aptos
当然如果你可以下载下来 git clone
https://github.com/aptos-labs/aptos-core.git
然后自己编译安装,参考教程>>
Hello World工程
- 创建目录,编写合约文件 你可以参考我的目录结构,然后创建相应的文件夹和文件。
mkdir HelloWorld
cd HelloWorld
➜ HelloWorld aptos init
Configuring for profile default
Choose network from [devnet, testnet, mainnet, local, custom | defaults to devnet]
testnet
Enter your private key as a hex literal (0x...) [Current: None | No input: Generate new key (or keep one if present)]
No key given, generating key...

Aptos CLI is now set up for account 0xb90343a98fc27691da66b9758887793932e89f3ed6d2fd22af5442e1b99271b4 as profile default!

{
"Result": "Success"
}
- 创建代码目录sources 和代码
module HelloAptos::Message{ use std::string; use std::error; use std::debug; use aptos_std::event; use std::signer;structMessage has key{ msg:string::String, message_change_events: event::EventHandle<MessageEvent>, }structMessageEvent has drop, store { from_message: string::String, to_message: string::String, }const ENO_MESSAGE: u64 = 0;public entry fun say_message(account:&signer, message_bytes: vector<u8>) acquires Message { let message = string::utf8(message_bytes); let account_addr = signer::address_of(account);if (!exists<Message>(account_addr)) { debug::print(&account_addr);move_to(account, Message { msg:message, message_change_events: event::new_event_handle<MessageEvent>(account), }); } else {// debug::print(message); let old_message = borrow_global_mut<Message>(account_addr); let from_message = *&old_message.msg; event::emit_event(&mut old_message.message_change_events, MessageEvent { from_message, to_message: copy message, }); old_message.msg = message; } }public fun get_message(addr: address): string::String acquires Message { assert!(exists<Message>(addr), error::not_found(ENO_MESSAGE)); *&borrow_global<Message>(addr).msg } #[test(account = @0x1)]public entry fun sender_can_set_message(account: signer) acquires Message { let addr = signer::address_of(&account);say_message(&account, b"Hello, Aptos"); assert!(get_message(addr) == string::utf8(b"Hello, Aptos"), ENO_MESSAGE ); }}
这个已经过时了,APTOS 在2023年-2025年有很大的变动,这个sdk已经不再支持。当前可行的一个发送message的写法如下
module HelloWorld::hello_world {
use std::string;
use std::error;
use std::option;
use std::signer;
/// define a resource
struct Message has key {
content: string::String,
}
/// initialize the resource (only allow one call per account)
public entry fun initialize(account: &signer, initial_message: string::String) {
assert!(
!exists<Message>(signer::address_of(account)),
error::already_exists(0)
);
move_to(account, Message { content: initial_message });
}
/// update the message
public entry fun update(account: &signer, new_message: string::String) acquires Message {
let addr = signer::address_of(account);
let msg = borrow_global_mut<Message>(addr);
msg.content = new_message;
}
/// read the message (can be used for view functions)
public fun get_message(addr: address): option::Option<string::String> acquires Message{
if (exists<Message>(addr)) {
let msg = borrow_global<Message>(addr);
option::some(msg.content)
} else {
option::none()
}
}
}
- 创建你的Move.toml 文件
[package]
name = "hello-world"
version = "0.0.1"
[dependencies]
AptosFramework = { git = “https://github.com/aptos-labs/aptos-core.git”, subdir = “aptos-move/framework/aptos-framework”, rev = “devnet” }
[addresses]
HelloWorld = “b90343a98fc27691da66b9758887793932e89f3ed6d2fd22af5442e1b99271b4”
其中 b90343a98fc27691da66b9758887793932e89f3ed6d2fd22af5442e1b99271b4 是我在第一步aptos init
的时候创建的地址公钥,你换成自己的就行
- 编译, 注意这一步需要保证github的畅通,它会自己去寻找依赖
➜ HelloWorld aptos move compile
Compiling, may take a little while to download git dependencies...
UPDATING GIT DEPENDENCY https://github.com/aptos-labs/aptos-core.git
INCLUDING DEPENDENCY AptosFramework
INCLUDING DEPENDENCY AptosStdlib
INCLUDING DEPENDENCY MoveStdlib

{

]
}
这就是成功了
- 发布

{

}
这个错是因为没钱,来点测试的钱吧
aptos account fund-with-faucet
{
"Error": "Invalid arguments: To get testnet APT you must visit https://aptos.dev/network/faucet. If you are confident you want to use a faucet programmatically, set --faucet-url or add a faucet URL to .aptos/config.yaml for the current profile"
}
devnet是可以直接获取到的,testnet 访问https://aptos.dev/network/faucet登录后
➜ HelloWorld aptos account balance
{
"Result": [
{
"asset_type": "coin",
"coin_type": "0x1::aptos_coin::AptosCoin",
"balance": 100000000
}
]
}
查询下余额
➜ HelloWorld aptos account balance
{
"Result": [
{
"asset_type": "coin",
"coin_type": "0x1::aptos_coin::AptosCoin",
"balance": 100000000
}
]
}
不再为0,再发布就ok了
