问如何使用node.js在Solana中保存键盘和发送令牌？

const solanaWeb3 = require("@solana/web3.js"),
const solanatoken = require("@solana/spl-token");

(async () => {
  // Connect to cluster
  var connection = new solanaWeb3.Connection(
    solanaWeb3.clusterApiUrl("devnet"),
    "confirmed"
  );

  // Generate a new wallet keypair and airdrop SOL
  var wallet = solanaWeb3.Keypair.generate();
  console.log("public key...", wallet.publicKey)
  // The stringPK is an example of what wallet.publicKey returns. When taking wallet.publicKey and using .toString(); it returns the decoded publicKey but that can't be used in an airdrop.
  const stringPK = `_bn: <BN: e8a4421b46f76fdeac76819ab21708cc4a4b9c9c7fc2a22e373443539cee1a81>`;
  console.log("private key...", JSON.stringify(wallet.secretKey.toString()));
  console.log(solanaWeb3.PublicKey.decode(wallet.publicKey));
  var airdropSignature = await connection.requestAirdrop(
    stringPK,
    solanaWeb3.LAMPORTS_PER_SOL
  );

  //wait for airdrop confirmation
  await connection.confirmTransaction(airdropSignature);

  let account = await connection.getAccountInfo(wallet.publicKey);
  console.log(account);
})();
