Solana Web3 confirmTransaction已过时，使用TransactionConfirmationConfig示例。

Question

使用这段代码，VS会显示一个废弃警告:

(方法) Connection.confirmTransaction(strategy: string, commitment?: Commitment): Promise<RpcResponseAndContext> (+1重载) @deprecated — 现在请使用TransactionConfirmationConfig调用confirmTransaction

'connection.confirmTransaction'的签名'(strategy: string, commitment?: Commitment): Promise<RpcResponseAndContext>'已过时

const airDropSol = async () => {
  try {
    const connection = new Connection(clusterApiUrl("devnet"), "confirmed");
    const airdropSignature = await connection.requestAirdrop(
      publicKey,
      2 * LAMPORTS_PER_SOL
    );
    await connection.confirmTransaction(airdropSignature);
  } catch (error) {
    console.error(error);
  }
};

有人可以给我一个使用新语法的例子吗？

不幸的是，看起来 文档仍然使用已弃用的方法。 - mikemaccana

Answer 1

新的方法签名看起来像这样

confirmTransaction(
  strategy: BlockheightBasedTransactionConfirmationStrategy,
  commitment?: Commitment,
): Promise<RpcResponseAndContext<SignatureResult>>;

所以，现在它期望的是BlockheightBasedTransactionConfirmationStrategy而不是之前的TransactionSignature

其中

type BlockheightBasedTransactionConfirmationStrategy = {
    signature: string;
} & Readonly<{
    blockhash: string;
    lastValidBlockHeight: number;
}>

因此，你需要的是：

Hence what you need is

  const airDropSol = async () => {
    try {
      const connection = new Connection(clusterApiUrl("devnet"), "confirmed");
      const airdropSignature = await connection.requestAirdrop(
        keypair.publicKey,
        2 * LAMPORTS_PER_SOL
      );

      const latestBlockHash = await connection.getLatestBlockhash();

      await connection.confirmTransaction({
        blockhash: latestBlockHash.blockhash,
        lastValidBlockHeight: latestBlockHash.lastValidBlockHeight,
        signature: airdropSignature,
      });
    } catch (error) {
      console.error(error);
    }
  };
