rust - 将 Solana 空投到特定帐户

Question

我想将 sols 空投到特定账户，让我的智能合约触发 anchor 测试。每当我运行测试时，我都会遇到错误 Error: Account BdFchxtKbEaWtsbuFX2nbKyZCjhz5LN8vyPukQzJQrME has insufficient funds for spend (1.30250136 SOL) + fee (0.000945 SOL) There was a problem deploying: Output { status: ExitStatus(ExitStatus(256)), stdout: "", stderr: "" }.

错误是不言自明的，但我如何向该特定帐户空投代币，我可以运行 solana airdrop 5但随后它将其空投到另一个帐户 GgRbD2AdibdAtBrQMJJEooco9gKt48Sd98Gn7vZQ1nJK。

我什至尝试使用 solana transfer BdFchxtKbEaWtsbuFX2nbKyZCjhz5LN8vyPukQzJQrME 5 --allow-unfunded-recipient 将代币从一个账户转移到另一个账户但交易只是挂起。

下面是我在 Rust 中使用 Anchor 的智能合约:

use anchor_lang::prelude::*;
use anchor_lang::solana_program::system_program;

declare_id!("BNDCEb5uXCuWDxJW9BGmbfvR1JBMAKckfhYrEKW2Bv1W");

#[program]
pub mod solana_twitter {
    use super::*;
    pub fn send_tweet(ctx: Context<SendTweet>, topic: String, content: String) -> ProgramResult {
        let tweet: &mut Account<Tweet> = &mut ctx.accounts.tweet;
        let author: &Signer = &ctx.accounts.author;
        let clock: Clock = Clock::get().unwrap();

        if topic.chars().count() > 50 {
            return Err(ErrorCode::TopicTooLong.into())
        }

        if content.chars().count() > 280 {
            return Err(ErrorCode::ContentTooLong.into())
        }

        tweet.author = *author.key;
        tweet.timestamp = clock.unix_timestamp;
        tweet.topic = topic;
        tweet.content = content;

        Ok(())
    }
}

#[derive(Accounts)]
pub struct SendTweet<'info> {
    #[account(init, payer = author, space = Tweet::LEN)]
    pub tweet: Account<'info, Tweet>,
    #[account(mut)]
    pub author: Signer<'info>,
    #[account(address = system_program::ID)]
    pub system_program: AccountInfo<'info>,
}

#[account]
pub struct Tweet {
    pub author: Pubkey,
    pub timestamp: i64,
    pub topic: String,
    pub content: String,
}

#[error]
pub enum ErrorCode {
    #[msg("The provided topic should be 50 characters long maximum.")]
    TopicTooLong,
    #[msg("The provided content should be 280 characters long maximum.")]
    ContentTooLong,
}

更新简单地空投到特定帐户有帮助，solana airdrop 3 <Account Address> .另一个相关问题是我的本地集群挂了，为了解决这个问题，我按照以下步骤操作:

1. 检查本地链是否正在运行 ps au
2. 终止本地 solana-test-validator 进程
3. 清理工作区 cargo clean
4. 删除了 node_modules rm -rf node_modules
5. 重新安装节点模块 yarn install
6. 重新运行测试 anchor 测试

Answer 1

首先，尝试确保您的 anchor.toml 的提供者部分像这样设置为测试网

[provider]
cluster = "testnet"
wallet = "/home/yourname/.config/solana/id.json"

此外，使用此命令为测试网设置集群

solana config set --url https://api.testnet.solana.com

检查您的 solana 运行节点中的事件帐户

solana address

它应该显示你的运行节点事件帐户公钥

另外，检查账户余额

solana balance

如果您没有足够的 sol 来运行测试或部署(测试后)，您可以通过运行来空投 sol

solana airdrop 2

重点是尝试一次(多次)空投 2 sol

现在您可以再次运行 anchor 测试(在 anchor 构建之后)
