如何通过 javascript 结构中的 public 键来锚定 rpc 方法

Question

我正在尝试将 public 密钥传递给锚点 rpc 方法，但认为我没有在 Javascript 中正确生成它，我尝试用引号和不引号填充它，但无济于事。锚点测试给了我一个 TypeError: key.toBuffer is not a function IF I pad it。如果我不填充它，那么我会收到错误错误：由帐户引起的 AnchorError：my_account。错误代码：AccountDidNotSerialize。错误号：3004。错误消息：序列化帐户失败。

我怀疑问题出在我的 javascript 代码上：

  const pubkey1 = anchor.web3.Keypair.generate();
  const signatory1 =
    {
      name: "matt",
      publicKey: pubkey1.publicKey, // Error Code: AccountDidNotSerialize. Error Number: 3004
      // publicKey: '"' + pubkey1.publicKey + '"', // TypeError: key.toBuffer is not a function
    };
    // Invoke the update rpc.
    await program.rpc.addSignatory(signatory1, {
      accounts: {
        myAccount: myAccount.publicKey,
      },
    });

完整代码如下。

Lib.rs

use anchor_lang::prelude::*;

declare_id!("Fg6PaFpoGXkYsidMpWTK6W2BeZ7FEfcYkg476zPFsLnS");

#[program]
mod basic_1 {
    use super::*;

    pub fn initialize(ctx: Context<Initialize>, data: u64) -> Result<()> {
        let my_account = &mut ctx.accounts.my_account;
        my_account.data = data;
        Ok(())
    }

    pub fn update(ctx: Context<Update>, data: u64) -> Result<()> {
        let my_account = &mut ctx.accounts.my_account;
        my_account.data = data;
        Ok(())
    }

    pub fn add_signatory(ctx: Context<Update>, signatory: Signatory) -> Result<()> {
        let my_account = &mut ctx.accounts.my_account;
        //my_account.data = data;
        my_account.signatories.push(signatory);
        Ok(())
    }

    pub fn add_signatories(ctx: Context<Update>, signatories: Vec<Signatory>) -> Result<()> {
        let my_account = &mut ctx.accounts.my_account;
        //my_account.data = data;
        my_account.signatories = signatories;
        Ok(())
    }


}

Answer 1

你误解了问题。这里的问题不在于公钥传递。

添加签字人时，您已运行名 space 名。

您需要做的是预先计算存储 vec 中允许存储的最大签名数所需的 space。它必须有界限。

请参考https://borsh.io/#pills-specification来计算您需要多少space。

要验证这一点，您可以将 space 从 100 更改为 1000

#[derive(Accounts)]
pub struct Initialize<'info> {
    #[account(init, payer = user, space = 1000)]
    pub my_account: Account<'info, MyAccount>,
    #[account(mut)]
    pub user: Signer<'info>,
    pub system_program: Program<'info, System>,
}

这对我来说很好

✔ Creates and initializes an account in a single atomic transaction (simplified) (186ms)
✔ Updates a previously created account (407ms)
✔ add a single signatory (409ms)
✔ add multiple signatories (414ms)
