代码示例

基本请求

curl https://fra.rpc.orbitflare.com?api_key=YOUR-API-KEY -X POST -H "Content-Type: application/json" -d '{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "getVoteAccounts"
}'

使用 web3.js

import { Connection } from '@solana/web3.js';

const connection = new Connection('https://fra.rpc.orbitflare.com?api_key=YOUR-API-KEY');

// Get vote accounts
const voteAccounts = await connection.getVoteAccounts();
console.log('Vote accounts:', voteAccounts);

// Get vote accounts with analysis
async function getVoteAccountsWithAnalysis(
  config: { 
    commitment?: string;
    votePubkey?: string;
    keepUnstakedDelinquents?: boolean;
    delinquentSlotDistance?: number;
  }
) {
  const voteAccounts = await connection.getVoteAccounts(config);
  
  return {
    voteAccounts,
    analysis: {
      current: {
        count: voteAccounts.current.length,
        totalStake: voteAccounts.current.reduce((sum, acc) => sum + acc.activatedStake, 0),
        averageStake: voteAccounts.current.reduce((sum, acc) => sum + acc.activatedStake, 0) / voteAccounts.current.length,
        activeVoters: voteAccounts.current.filter(acc => acc.epochVoteAccount).length
      },
      delinquent: {
        count: voteAccounts.delinquent.length,
        totalStake: voteAccounts.delinquent.reduce((sum, acc) => sum + acc.activatedStake, 0),
        averageStake: voteAccounts.delinquent.reduce((sum, acc) => sum + acc.activatedStake, 0) / voteAccounts.delinquent.length,
        activeVoters: voteAccounts.delinquent.filter(acc => acc.epochVoteAccount).length
      },
      metadata: {
        timestamp: Date.now(),
        commitment: config.commitment
      }
    }
  };
}

注意事项

返回当前的投票账户
响应包括当前和失效的投票账户
响应是即时的，因为它从当前状态读取
账户可能随质押变化和投票而变化
投票账户必须有效

最佳实践

根据需求使用适当的 commitment 级别
在适当时缓存结果以减少 RPC 负载
监控投票账户的变化
考虑使用 WebSocket 订阅获取实时更新
适当处理网络错误并重试

常见错误

错误码	消息	解决方案
-32601	Method not found	验证是否连接到 Solana RPC 节点
-32602	Invalid params	检查配置参数
-32007	Vote account not found	验证投票账户是否存在
