我怎样才能得到 collection 糖果机的 public 钥匙

Question

请帮助我获得 NFT Mint 地址和下面这个功能 return 我想要的但它需要糖果机 ID :

import { Connection, clusterApiUrl, PublicKey } from '@solana/web3.js';
import bs58 from 'bs58';

const connection = new Connection(clusterApiUrl('mainnet-beta'));
const MAX_NAME_LENGTH = 32;
const MAX_URI_LENGTH = 200;
const MAX_SYMBOL_LENGTH = 10;
const MAX_CREATOR_LEN = 32 + 1 + 1;
const MAX_CREATOR_LIMIT = 5;
const MAX_DATA_SIZE = 4 + MAX_NAME_LENGTH + 4 + MAX_SYMBOL_LENGTH + 4 + MAX_URI_LENGTH + 2 + 1 + 4 + MAX_CREATOR_LIMIT * MAX_CREATOR_LEN;
const MAX_METADATA_LEN = 1 + 32 + 32 + MAX_DATA_SIZE + 1 + 1 + 9 + 172;
const CREATOR_ARRAY_START = 1 + 32 + 32 + 4 + MAX_NAME_LENGTH + 4 + MAX_URI_LENGTH + 4 + MAX_SYMBOL_LENGTH + 2 + 1 + 4;

const TOKEN_METADATA_PROGRAM = new PublicKey('metaqbxxUerdq28cj1RbAWkYQm3ybzjb6a8bt518x1s');
const candyMachineId = new PublicKey('ENTER_YOUR_CANDY_MACHINE_ID_HERE');

const getMintAddresses = async (firstCreatorAddress: PublicKey) => {
  const metadataAccounts = await connection.getProgramAccounts(
    TOKEN_METADATA_PROGRAM,
    {
      // The mint address is located at byte 33 and lasts for 32 bytes.
      dataSlice: { offset: 33, length: 32 },

      filters: [
        // Only get Metadata accounts.
        { dataSize: MAX_METADATA_LEN },

        // Filter using the first creator.
        {
          memcmp: {
            offset: CREATOR_ARRAY_START,
            bytes: firstCreatorAddress.toBase58(),
          },
        },
      ],
    },
  );

  return metadataAccounts.map((metadataAccountInfo) => (
    bs58.encode(metadataAccountInfo.account.data)
  ));
};

getMintAddresses(candyMachineId);

当你 运行 candy-machine-v2-cli.ts 上传时，它应该将新创建的糖果机 ID 打印到你的控制台。

但是，鉴于您搜索创作者，您实际上需要使用与糖果机关联的糖果机 创作者 id。这个和糖果机Id本身是不一样的

您可以在任何铸造资产的元数据中找到糖果机创建者 ID。糖果机创建者id将是第一个创建者份额为0的列表创建者。
