主网NFT的发布合约

1.什么是nft?

NFT:Non-fungible-token
非同质化货币

2.新建suimove项目

使用sui move new 项目名命令新建sui move项目

sui move new nft_qyx

项目结构如下:

3.写nft合约

module qyx123::nft{use sui::object::{Self, UID};use sui::transfer;use sui::tx_context::{Self, TxContext};use sui::display;use sui::package;use std::string::utf8;struct NFT has drop {}//我的nft结构体,属性id和tokenidstruct MyNFT has key,store{id: UID,tokenId: u64}struct State has key {id: UID,count: u64}fun init(witness: NFT, ctx:&mut TxContext){//键值对,键名和值一一对应//键名let keys = vector[utf8(b"name"),utf8(b"collection"),utf8(b"image_url"),utf8(b"description")];//value值let values = vector[utf8(b"MyNFT #{tokenId}"),utf8(b"MyNFT Collection"),utf8(b"自己的头像地址"),utf8(b"This is My NFT")];//使用 packge和display发布地址//创建发布者let publisher = package::claim(witness,ctx);//创建displaylet display = display::new_with_fields<MyNFT>(&publisher, keys, values, ctx);display::update_version(&mut display);transfer::public_transfer(publisher, tx_context::sender(ctx));transfer::public_transfer(display, tx_context::sender(ctx));//计数器transfer::share_object(State{id: object::new(ctx),count: 0});}entry public fun mint( state:&mut State, ctx: &mut TxContext){let sender = tx_context::sender(ctx);//计数器state.count = state.count + 1;let nft = MyNFT {id: object::new(ctx),tokenId: state.count,};transfer::public_transfer(nft, sender);}}

4.引入图片

找到一张图片,转为base64,代码放到上面的value中的图像地址中

		//value值let values = vector[utf8(b"MyNFT #{tokenId}"),utf8(b"MyNFT Collection"),utf8(b"自己的头像地址"),//此处utf8(b"This is My NFT")];

5.发布到开发网testnet

5.1列出当前所有网络别名和当前网络:

sui client envs

此处显示我目前为devnet

5.2切换网络命令可以切换到对应网络

切换网络:

sui client switch --env [network alias]

5.3编译代码

跳过拉取最新git依赖

sui move build --skip-fetch-latest-git-deps

编辑不通过记得在mint函数前加上

  #[lint_allow(self_transfer)]

编译通过

5.4发布到testnet

sui move test  --skip-fetch-latest-git-depssui client publish --skip-fetch-latest-git-deps --skip-dependency-verification --gas-budget 500000000

不成功在init函数前加上

    #[allow(unused_function)]

发布成功

通过sui浏览器查询packageID

6.mint

复制计数器id到mint处执行
支付后mint成功
