调用web3.sendrawtransaction（signature.serialize（））时出错

我想签署来自Phantom Wallet的用户交易，然后通过Web3.js发送交易，但是成功签署了交易后，Web3JS库函数sendrawtransaction（）给出控制台中的错误消息

const signedTransaction = await window.solana.signTransaction(transaction);
const signature = await connection.sendRawTransaction(signedTransaction.serialize());
await connection.confirmTransaction(signature);

I want to sign a transaction of a user from phantom wallet and then send the transaction through web3.js but after successfully signing the transaction the web3js library function sendRawTransaction() is giving error message in console

const signedTransaction = await window.solana.signTransaction(transaction);
const signature = await connection.sendRawTransaction(signedTransaction.serialize());
await connection.confirmTransaction(signature);

如果您查看sendtransaction的实现，您会发现它在签名，序列化和发送之前向交易中添加了一个块。如果没有阻止，您将获得该错误blockhash找不到。因此，相反，您需要执行以下操作：

const latestBlockhash = await connection.getLatestBlockhash();
transaction.lastValidBlockHeight = latestBlockhash.lastValidBlockHeight;
transaction.recentBlockhash = latestBlockhash.blockhash;
const signedTransaction = await window.solana.signTransaction(transaction);
const signature = await connection.sendRawTransaction(signedTransaction.serialize());
await connection.confirmTransaction(signature);

sendtransaction的完整实现 https://github.com/solana-labs/solana/solana/solana/blob/3fcdc45092b969b969b969baeb7273de65969699999998277773666/weection

If you look at the implementation of sendTransaction, you'll see that it's adding a blockhash to the transaction before signing, serializing, and sending. Without a blockhash, you'll get that error Blockhash not found. So instead, you need to do something like:

const latestBlockhash = await connection.getLatestBlockhash();
transaction.lastValidBlockHeight = latestBlockhash.lastValidBlockHeight;
transaction.recentBlockhash = latestBlockhash.blockhash;
const signedTransaction = await window.solana.signTransaction(transaction);
const signature = await connection.sendRawTransaction(signedTransaction.serialize());
await connection.confirmTransaction(signature);
