Let's move - Sui NFT发布

本文转自本人微信公众号的文章，所以带有wx水印，希望大家能理解一下。后续新文会自己留存不带水印。

**1.1 创建合约stomnft**

```
module stomnft::stomnft{
    use sui::tx_context::{sender, TxContext};
    use std::string::{utf8, String};
    use sui::transfer;
    use sui::object::{Self, UID};
    use sui::package;
    use sui::display;

struct StomNFT has key, store {
        id: UID,
        tokenId: u64
    }

struct STOMNFT has drop {}

struct State has key {
        id: UID,
        count: u64
    }

#[allow(unused_function)]
    fun init(witness: STOMNFT, ctx: &mut TxContext) {
        let keys = vector[
            utf8(b"name"),
            utf8(b"image_url"),
            utf8(b"description"),
        ];

let values = vector[
            // For `name` we can use the `.name` property
            utf8(b"STOMNFT"),
            utf8(b"https://avatars.githubusercontent.com/baicaiyihao"),
            utf8(b"github:baicaiyihao"),
        ];

let publisher = package::claim(witness, ctx);

let display = display::new_with_fields<StomNFT>(
            &publisher, keys, values, ctx
        );

display::update_version(&mut display);

transfer::public_transfer(publisher, sender(ctx));
        transfer::public_transfer(display, sender(ctx));
        
        transfer::share_object(State{
            id: object::new(ctx),
            count: 0
        });
    
    }

#[lint_allow(self_transfer)]
    public entry fun mint(state: &mut State, ctx: &mut TxContext){
        state.count = state.count + 1;
        let nft = StomNFT { 
            id:object::new(ctx),
            tokenId:state.count
        };
        transfer::public_transfer(nft,sender(ctx));
    }
}

```

发布合约，获取State objectid和packageid

**1.2 实现自定义参数传入**

struct StomNFT has key, store {
        id: UID,
        name:String,
        description:String,
        image_url:String,
        tokenId: u64
    }

struct STOMNFT has drop {}

struct State has key {
        id: UID,
        count: u64
    }

let values = vector[
            utf8(b"{name}"),
            utf8(b"{image_url}"),
            utf8(b"{description}"),
        ];

let publisher = package::claim(witness, ctx);

let display = display::new_with_fields<StomNFT>(
            &publisher, keys, values, ctx
        );

display::update_version(&mut display);

#[lint_allow(self_transfer)]
    public entry fun mint(state: &mut State,name:String,description:String,image_url:String, ctx: &mut TxContext){
        state.count = state.count + 1;
        let nft = StomNFT { 
            id:object::new(ctx),
            name:name,
            description:description,
            image_url:image_url,
            tokenId:state.count
        };
        transfer::public_transfer(nft,sender(ctx));
    }
}
```

修改了StomNFT{}，新增了name，description，image_url实现自己自定义发布NFT，通过自己传入参数来创建想要的NFT name和image等。

发布合约

调用mint

1.1 创建合约stomnft

module stomnft::stomnft{
    use sui::tx_context::{sender, TxContext};
    use std::string::{utf8, String};
    use sui::transfer;
    use sui::object::{Self, UID};
    use sui::package;
    use sui::display;

    struct StomNFT has key, store {
        id: UID,
        tokenId: u64
    }

    struct STOMNFT has drop {}

    struct State has key {
        id: UID,
        count: u64
    }

    #[allow(unused_function)]
    fun init(witness: STOMNFT, ctx: &mut TxContext) {
        let keys = vector[
            utf8(b"name"),
            utf8(b"image_url"),
            utf8(b"description"),
        ];

        let values = vector[
            // For `name` we can use the `.name` property
            utf8(b"STOMNFT"),
            utf8(b"https://avatars.githubusercontent.com/baicaiyihao"),
            utf8(b"github:baicaiyihao"),
        ];

        let publisher = package::claim(witness, ctx);

        let display = display::new_with_fields&lt;StomNFT>(

        display::update_version(&mut display);

        transfer::public_transfer(publisher, sender(ctx));
        transfer::public_transfer(display, sender(ctx));

        transfer::share_object(State{

    }


    #[lint_allow(self_transfer)]
    public entry fun mint(state: &mut State, ctx: &mut TxContext){
        state.count = state.count + 1;
