锚/索拉纳错误0xbc2(3010)—给定的帐户未签名

Question

我在Golang中的锚交易，尽管在锚JS代码中工作良好，但不想玩得很好，并且给了我一个关于签名者帐户(在这种情况下称为authority)没有签名的错误消息，即使我确实签署了。

我的指令代码结构是这样的:

#[account]
#[derive(Default)]
pub struct Device {
pub ipv4: [u8; 4],
pub hostname: String,
bump: u8,
status: DeviceStatus,
local_key: Pubkey,
}
#[derive(Accounts)]
#[instruction(local_key: Pubkey)]
pub struct RegisterDevice<'info> {
#[account(init,
space = 128,
seeds = [local_key.as_ref()],
bump,
payer = authority,
)]
pub device: Box<Account<'info, Device>>,
#[account(mut)]
pub authority: Signer<'info>,
pub system_program: Program<'info, System>,
}

我的锚代码工作正常，看起来像这样:

it("registers a device", async () => {
const localKey = anchor.web3.Keypair.generate();
const [devicePDA, _devicePDABump] =
await anchor.web3.PublicKey.findProgramAddress(
[localKey.publicKey.toBuffer()],
program.programId
);
await program.methods
.registerDevice(localKey.publicKey)
.accounts({
device: devicePDA,
authority: provider.wallet.PublicKey,
systemProgram: SystemProgram.programId,
})
.rpc();
});

Go代码(使用solana-go库):

registerDeviceInst, err := worknet.NewRegisterDeviceInstruction(
devicePubkey,
pdaPubkey,
*walletPubKey,
gagliardetto.SystemProgramID,
).ValidateAndBuild()
if err != nil {
return err
}
blockHash, err := client.GetRecentBlockhash(context.TODO(), gagliardettorpc.CommitmentFinalized)
if err != nil {
return nil
}
txn, err := gagliardetto.NewTransaction([]gagliardetto.Instruction{registerDeviceInst}, blockHash.Value.Blockhash)
if err != nil {
return err
}
_, err = txn.Sign(func(key gagliardetto.PublicKey) *gagliardetto.PrivateKey {
return walletPrivKey
})
if err != nil {
return err
}

以下是TXN的转储和响应:

锚JS做什么魔法，我在我的Go客户端代码缺失?

Answer 1

好的，我已经成功地找出了问题所在。

阅读https://docs.solana.com/developing/programming-model/transactions，我注意到它提到:

Solana runtime…验证每个签名都是由与同一索引上的公钥对应的私钥签名的。在消息的帐户地址数组中。

如果你看一下我在Go代码中传递的帐户，authority位于索引1，而不是像它的签名那样索引0:

└─ Accounts[len=3]
├─ device: HqhAGJwjHo36AJwfPzaWAu224rVF9bDWnN9tx6JSdjot [WRITE] 
├─ authority: HEwe5nVn4y2gV4tCQ3hZ6a3QxB9a72NyXstWxBk4q5ct [WRITE, SIGN] 
└─ systemProgram: 11111111111111111111111111111111 [] 

因此，解决方案是改变锚结构定义中帐户的顺序，重新生成Go绑定，并以正确的顺序传递帐户，以便authority帐户在事务中索引为0。

#[derive(Accounts)]
#[instruction(local_key: Pubkey)]
pub struct RegisterDevice<'info> {
+    #[account(mut)]
+    pub authority: Signer<'info>,
+
#[account(init,
space = 128,
seeds = [local_key.as_ref()],
bump,
payer = authority,
)]
pub device: Box<Account<'info, Device>>,

-    #[account(mut)]
-    pub authority: Signer<'info>,
pub system_program: Program<'info, System>,
}

现在交易符号正确。我认为导致锚代码工作的原因是它将在RPC调用中执行一些自动帐户解析，这将正确地放置授权/签名(?)，尽管它在生成的Go代码中无序。
