无法使用 solana-py 签署部分签名的交易

Question

为了在 MagicEden 上购买东西，我使用了一个名为 buy_now 的端点，它向我发送了以下格式的有效载荷：

使用 ['tx']['data'] 消息和 ['txSigned']['data'] 部分签名的交易。 我正在尝试签署消息并将其插入交易的第一个签名 [] 插槽中。

入口中的有效载荷：

这是我的代码：

  txSigned = tx_data['txSigned']['data']
  tx = bytes(tx_data['tx']['data'])
  client = AsyncClient("https://api.mainnet-beta.solana.com")
  payer = Keypair.from_secret_key(b58decode(mypkey))
  sig = payer.sign(tx)
  tra = Transaction.deserialize(bytes(txSigned))
  tra.signatures[0].signature = sig.signature
  
  tra = Transaction.serialize(tra)
  txn = await client.send_raw_transaction(tra)

我一直遇到：'交易未正确签署'

有类似问题但使用 C# solnet 的人： https ://github.com/bmresearch/Solnet/issues/399

这是一个错误吗？ 多谢

这是有道理的，因为之前来自 Magic Eden 的签名在tra.signatures[0].signature = sig.signature期间被删除

相反，您应该反序列化交易，然后自己签名，例如：

tra = Transaction.deserialize(bytes(txSigned))
tra.sign(payer)  
tra = Transaction.serialize(tra)
txn = await client.send_raw_transaction(tra)
