我如何获得集合的糖果机的公钥?

Question

请帮助我想获得NFT薄荷地址，下面的函数返回我想要的，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);

运行candy-machine-v2-cli时。在上传之前，它应该将新创建的糖果机ID打印到您的控制台。

然而，考虑到您正在搜索创建者，您实际上需要使用与糖果机相关联的糖果机creatorid。这与糖果机Id本身不同。

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将是创建者列表中第一个创建者共享值为0的创建者。
