您可以按所有者获取代币账户。有两种方法可以做到这一点。

1. 获取所有代币账户

import { clusterApiUrl, Connection, PublicKey } from "@solana/web3.js";
import { TOKEN_PROGRAM_ID } from "@solana/spl-token";

(async () => {
  // connection
  const connection = new Connection(clusterApiUrl("devnet"), "confirmed");

  const owner = new PublicKey("G2FAbFQPFa5qKXCetoFZQEvF9BVvCKbvUZvodpVidnoY");
  let response = await connection.getParsedTokenAccountsByOwner(owner, {
    programId: TOKEN_PROGRAM_ID,
  });

  response.value.forEach(accountInfo => {
    console.log(`pubkey: ${accountInfo.pubkey.toBase58()}`);
    console.log(`mint: ${accountInfo.account.data["parsed"]["info"]["mint"]}`);
    console.log(
      `owner: ${accountInfo.account.data["parsed"]["info"]["owner"]}`,
    );
    console.log(
      `decimals: ${accountInfo.account.data["parsed"]["info"]["tokenAmount"]["decimals"]}`,
    );
    console.log(
      `amount: ${accountInfo.account.data["parsed"]["info"]["tokenAmount"]["amount"]}`,
    );
    console.log("====================");
  });
})();

2. 通过Mint过滤

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

(async () => {
  // connection
  const connection = new Connection(clusterApiUrl("devnet"), "confirmed");

  const owner = new PublicKey("G2FAbFQPFa5qKXCetoFZQEvF9BVvCKbvUZvodpVidnoY");
  const mint = new PublicKey("54dQ8cfHsW1YfKYpmdVZhWpb9iSi6Pac82Nf7sg3bVb");

  let response = await connection.getParsedTokenAccountsByOwner(owner, {
    mint: mint,
  });

  response.value.forEach(accountInfo => {
    console.log(`pubkey: ${accountInfo.pubkey.toBase58()}`);
    console.log(`mint: ${accountInfo.account.data["parsed"]["info"]["mint"]}`);
    console.log(
      `owner: ${accountInfo.account.data["parsed"]["info"]["owner"]}`,
    );
    console.log(
      `decimals: ${accountInfo.account.data["parsed"]["info"]["tokenAmount"]["decimals"]}`,
    );
    console.log(
      `amount: ${accountInfo.account.data["parsed"]["info"]["tokenAmount"]["amount"]}`,
    );
    console.log("====================");
  });
})();
