深入探索 Aptos Move：Object 配置与实操指南

Aptos Move 是一门专为区块链设计的编程语言，以其模块化与高效性著称。在 Move 生态系统中，Object 是一个核心概念，它为开发者提供了灵活的资源管理工具。本文章将详细介绍如何配置和使用 Move 中的 Object，以及实操步骤帮助开发者更好地理解与应用这一关键功能。

本文重点介绍 Aptos Move 中的 Object 配置与使用方法，详细解释了如何创建和自定义 Object、控制其行为、转移管理、受控转移及删除权限等内容。文章还通过实操演示了如何创建、发布并调用 Object 相关方法，帮助开发者快速上手并掌握 Object 的配置技巧和编程流程。

OBJECT 配置与使用

object 有哪些配置？

扩展对象：将对象变成可动态配置的，可以往里面添置新的 Struct 资源
转移管理：可以开启或者禁用 object transfer 功能
受控转移：仅可使用一次转移功能
允许删除：允许删除对象

Creating an Object involves two steps:

Creating the ObjectCore resource group (which has an address you can use to refer to the Object later).
Customizing how the Object will behave using permissions called Refs.

实操

第一步：创建项目并初始化

hello_aptos on  main via  base

mcd lesson10

hello_aptos/lesson10 on  main via  base

aptos move init --name lesson10
{
  "Result": "Success"
}

hello_aptos/lesson10 on  main [?] via  base

aptos init

}

第二步：实现代码

`main.move`

module lesson10::MyObject {
    use std::signer;
    use aptos_framework::object;
    use aptos_framework::object::{Object, ObjectGroup};

    #[resource_group_member(group = ObjectGroup)]
    struct MyStruct has key {
        num: u8
    }

    entry fun create(caller: &signer) {
        let caller_address = signer::address_of(caller);
        let obj_ref = object::create_object(caller_address);
        let obj_signer = object::generate_signer(&obj_ref);

        move_to(&obj_signer, MyStruct { num: 42 })
    }
}

第三步：compile 发布

第四十步：调用`switch_transfer` 方法

Transaction:

0x483752217542f5411050e2c885076a2b81864c6e70ff3b0e054c973ed87d6975

https://explorer.aptoslabs.com/txn/0x483752217542f5411050e2c885076a2b81864c6e70ff3b0e054c973ed87d6975?network=devnet

调用switch_transfer 后不能再 transfer了

第四十一步：调用`transfer` 方法验证

点击 RUN

报错：The object does not have ungated transfers enabled

成功验证了switch_transfer后是不能transfer 的！

第四十二步：调用 `delete` 方法

调用之前：

调用之后：

成功删除！

扩展：update transfer 可以增加限制功能！

object 源码参考

    /// Create a new named object and return the ConstructorRef. Named objects can be queried globally
    /// by knowing the user generated seed used to create them. Named objects cannot be deleted.
    public fun create_named_object(creator: &signer, seed: vector&lt;u8>): ConstructorRef {
        let creator_address = signer::address_of(creator);
        let obj_addr = create_object_address(&creator_address, seed);
        create_object_internal(creator_address, obj_addr, false)
    }

    /// Create a new object whose address is derived based on the creator account address and another object.
    /// Derivde objects, similar to named objects, cannot be deleted.
    public(friend) fun create_user_derived_object(creator_address: address, derive_ref: &DeriveRef): ConstructorRef {
        let obj_addr = create_user_derived_object_address(creator_address, derive_ref.self);
        create_object_internal(creator_address, obj_addr, false)
    }

    /// Create a new object by generating a random unique address based on transaction hash.
    /// The unique address is computed sha3_256([transaction hash | auid counter | 0xFB]).
    /// The created object is deletable as we can guarantee the same unique address can
    /// never be regenerated with future txs.
    public fun create_object(owner_address: address): ConstructorRef {
        let unique_address = transaction_context::generate_auid_address();
        create_object_internal(owner_address, unique_address, true)
    }

    /// Same as `create_object` except the object to be created will be undeletable.
    public fun create_sticky_object(owner_address: address): ConstructorRef {
        let unique_address = transaction_context::generate_auid_address();
        create_object_internal(owner_address, unique_address, false)
    }

总结

通过本文的讲解与实操，读者应已掌握 Aptos Move 中 Object 的核心概念与配置方法。Object 的动态扩展性和受控转移功能赋予了开发者更大的灵活性，使资源管理更加便捷与安全。借助这些工具，开发者能够更高效地构建复杂的区块链应用。
