如何從solana交易簽名中獲取發送方和接收方的錢包ID？

Question

我有 Solana 交易的簽名，我想找到發送方和接收方的錢包 ID。 這就是我所做的：

const connection = new Web3.Connection(Web3.clusterApiUrl("devnet"), "confirmed");
const transaction = await connection.getTransaction(signature);

當我執行console.log(transaction)時，它有blockTime等字段，但to from地址。 有人可以幫忙嗎？

當調用getTransaction時，節點將以指定的格式返回交易。 默認情況下， connection.getTransaction將返回帶有 base58 編碼的事務，因此請嘗試改用connection.getParsedTransaction 。 這是一個簡單傳輸的示例：

curl https://api.devnet.solana.com -X POST -H "Content-Type: application/json" -d '

在result.transaction.message.instructions[0].parsed你會得到你想要的。
