我正在关注 solana-web3 文档。

使用splToken.Token.createMint

我能够获得交易 ID 和签名，并能够在资源管理器中查看它们。

如何在铸造时传递我的 NFT 的名称、符号和 iamge URI？我已经尝试过 metaplex 和 token-metadata 标准。但是solana中的资源似乎非常低。

任何人都可以帮助解决这个问题吗？

    web3.clusterApiUrl('devnet'),
    'confirmed',

  // Generate a new wallet keypair and airdrop SOL
  var fromWallet = web3.Keypair.generate();
  console.log("creating a from wallet ",fromWallet);
  var fromAirdropSignature = await connection.requestAirdrop(
    fromWallet.publicKey,
    web3.LAMPORTS_PER_SOL,
  );
  // Wait for airdrop confirmation
  await connection.confirmTransaction(fromAirdropSignature);

  // Generate a new wallet to receive newly minted token
  const toWallet = web3.Keypair.generate();

  // Create new token mint
  const mint = await splToken.Token.createMint(

    fromWallet,
    fromWallet.publicKey,
    null,

  console.log("connection details -->",connection);

  // Get the token account of the fromWallet Solana address, if it does not exist, create it

  await mint.mintTo(
