Ripple 账户标志设置

账户标志用于配置 Ripple 账户的各种行为和权限，通过 AccountSet 交易类型来设置。

🚀 快速开始​

环境准备​

npm install ripple-lib

基本设置​

const RippleAPI = require('ripple-lib').RippleAPI;

// 创建 API 实例
const api = new RippleAPI({
  server: 'wss://s.altnet.rippletest.net/', // 测试网
  // server: 'wss://s1.ripple.com/', // 主网
});

📝 账户标志类型​

1. 全局标志 (Global Flags)​

const GLOBAL_FLAGS = {
  // 禁用主密钥
  DISABLE_MASTER: 0x00100000,
  
  // 要求授权信任线
  REQUIRE_AUTH: 0x00040000,
  
  // 要求目的地标签
  REQUIRE_DEST_TAG: 0x00020000,
  
  // 禁用信任线
  DISALLOW_XRP: 0x00080000,
  
  // 允许信任线
  ALLOW_XRP: 0x00080000,
};

2. 设置标志 (Set Flags)​

const SET_FLAGS = {
  // 设置要求授权信任线
  REQUIRE_AUTH: 0x00040000,
  
  // 设置要求目的地标签
  REQUIRE_DEST_TAG: 0x00020000,
  
  // 设置禁用信任线
  DISALLOW_XRP: 0x00080000,
  
  // 设置禁用主密钥
  DISABLE_MASTER: 0x00100000,
  
  // 设置默认信任线
  DEFAULT_RIPPLE: 0x00800000,
  
  // 设置不冻结
  NO_FREEZE: 0x00200000,
  
  // 设置全局冻结
  GLOBAL_FREEZE: 0x00400000,
};

3. 清除标志 (Clear Flags)​

const CLEAR_FLAGS = {
  // 清除要求授权信任线
  CLEAR_REQUIRE_AUTH: 0x00040000,
  
  // 清除要求目的地标签
  CLEAR_REQUIRE_DEST_TAG: 0x00020000,
  
  // 清除禁用信任线
  CLEAR_DISALLOW_XRP: 0x00080000,
  
  // 清除禁用主密钥
  CLEAR_DISABLE_MASTER: 0x00100000,
  
  // 清除默认信任线
  CLEAR_DEFAULT_RIPPLE: 0x00800000,
  
  // 清除不冻结
  CLEAR_NO_FREEZE: 0x00200000,
  
  // 清除全局冻结
  CLEAR_GLOBAL_FREEZE: 0x00400000,
};

🔄 账户标志设置流程​

1. 连接网络​

async function connectToNetwork() {
  try {
    await api.connect();
    console.log('Connected to Ripple network');
  } catch (error) {
    console.error('Connection failed:', error);
  }
}

2. 查询当前标志​

async function getCurrentFlags(accountAddress) {
  try {
    const account = await api.getAccountInfo(accountAddress);
    
    const flags = {
      flags: account.Flags || 0,
      flagsHex: '0x' + (account.Flags || 0).toString(16).toUpperCase(),
      flagsSet: [],
      flagsClear: [],
    };
    
    // 解析已设置的标志
    if (account.Flags & SET_FLAGS.REQUIRE_AUTH) flags.flagsSet.push('REQUIRE_AUTH');
    if (account.Flags & SET_FLAGS.REQUIRE_DEST_TAG) flags.flagsSet.push('REQUIRE_DEST_TAG');
    if (account.Flags & SET_FLAGS.DISALLOW_XRP) flags.flagsSet.push('DISALLOW_XRP');
    if (account.Flags & SET_FLAGS.DISABLE_MASTER) flags.flagsSet.push('DISABLE_MASTER');
    if (account.Flags & SET_FLAGS.DEFAULT_RIPPLE) flags.flagsSet.push('DEFAULT_RIPPLE');
    if (account.Flags & SET_FLAGS.NO_FREEZE) flags.flagsSet.push('NO_FREEZE');
    if (account.Flags & SET_FLAGS.GLOBAL_FREEZE) flags.flagsSet.push('GLOBAL_FREEZE');
    
    console.log('Current account flags:', flags);
    return flags;
  } catch (error) {
    console.error('Failed to get current flags:', error);
  }
}

3. 准备设置标志交易​

async function prepareSetFlags(accountAddress, flags, clearFlags = 0) {
  try {
    const preparedTx = await api.prepareTransaction(
      {
        TransactionType: 'AccountSet',
        Account: accountAddress,
        Flags: flags,
        ClearFlag: clearFlags,
      },
      {
        maxLedgerVersionOffset: 75,
      }
    );
    
    console.log('Set flags transaction prepared:', preparedTx);
    return preparedTx;
  } catch (error) {
    console.error('Failed to prepare set flags transaction:', error);
  }
}

4. 签名和提交​

async function signAndSubmitFlags(preparedTx, secret) {
  try {
    // 签名交易
    const signed = api.sign(preparedTx.txJSON, secret);
    console.log('Flags transaction signed');
    console.log('Transaction ID:', signed.id);
    
    // 提交交易
    const result = await api.submit(signed.signedTransaction);
    console.log('Flags transaction submitted');
    console.log('Result code:', result.resultCode);
    console.log('Result message:', result.resultMessage);
    
    return result;
  } catch (error) {
    console.error('Failed to sign and submit flags transaction:', error);
  }
}

    // 2. 查询当前标志
    const currentFlags = await getCurrentFlags(account_address);
    console.log('Current flags:', currentFlags);
    
    // 3. 设置新标志
    const newFlags = SET_FLAGS.REQUIRE_AUTH | SET_FLAGS.REQUIRE_DEST_TAG;
    
    const preparedTx = await prepareSetFlags(account_address, newFlags);
    
    // 4. 签名和提交
    const result = await signAndSubmitFlags(preparedTx, secret);
    
    // 5. 验证设置结果
    if (result.resultCode === 'tesSUCCESS') {
      console.log('Flags successfully set!');
      
      // 等待几个账本确认
      await new Promise(resolve => setTimeout(resolve, 5000));
      
      // 验证新标志
      const updatedFlags = await getCurrentFlags(account_address);
      console.log('Updated flags:', updatedFlags);
    }
    
    // 6. 断开连接

📚 最佳实践​

  1. 谨慎设置: 仔细考虑每个标志的影响
  2. 测试验证: 在测试网上测试标志配置
  3. 文档记录: 记录所有标志变更的原因和影响
  4. 定期审查: 定期审查标志配置的合理性
  5. 备份配置: 备份重要的标志配置信息
  6. 权限控制: 限制标志修改的权限
