Solana WebSocket 快速入门指南

快速入门指南

获取您的 API 密钥

从 dashboard 获取您的 Helius API 密钥。您需要它进行身份验证。代理可以使用 the Helius CLI 获取密钥。

选择您的网络

选择适当的 endpoint:

Mainnet: wss://mainnet.helius-rpc.com/?api-key=YOUR_API_KEY
Mainnet (Gatekeeper Beta): wss://beta.helius-rpc.com/?api-key=YOUR_API_KEY
Devnet: wss://devnet.helius-rpc.com/?api-key=YOUR_API_KEY

创建您的第一个连接

const ws = new WebSocket('wss://mainnet.helius-rpc.com/?api-key=YOUR_API_KEY');

ws.onopen = () => {
  console.log('Connected to Solana!');
};

ws.onmessage = (event) => {
  const data = JSON.parse(event.data);
  console.log('Received:', data);
};

订阅更新

// Subscribe to account changes
const subscribeMessage = {
  "jsonrpc": "2.0",
  "id": 1,
  "method": "accountSubscribe",
  "params": [
    "ACCOUNT_ADDRESS_HERE",
    { "commitment": "confirmed" }
  ]
};

ws.send(JSON.stringify(subscribeMessage));

订阅方法

账户监控

监控特定账户的余额变化、数据更新或所有权转移。

const ws = new WebSocket('wss://mainnet.helius-rpc.com/?api-key=YOUR_API_KEY');

const subscribeToAccount = (accountAddress) => {
  const request = {
    "jsonrpc": "2.0",
    "id": 1,
    "method": "accountSubscribe",
    "params": [
      accountAddress,
      {
        "encoding": "jsonParsed",
        "commitment": "confirmed"
      }
    ]
  };
  
  ws.send(JSON.stringify(request));
};

ws.onmessage = (event) => {
  const data = JSON.parse(event.data);
  
  if (data.method === "accountNotification") {
    console.log("Account updated:", data.params.result.value);
    
    // Handle the account change
    const accountInfo = data.params.result.value;
    console.log(`New balance: ${accountInfo.lamports} lamports`);
  }
};

// Subscribe to a wallet address
subscribeToAccount("9PejEmViKHgUkVFWN57cNEZnFS4Qo6SzsLj5UPAXfDTF");

const ws = new WebSocket('wss://mainnet.helius-rpc.com/?api-key=YOUR_API_KEY');

// Monitor a token account for balance changes
const monitorTokenAccount = (tokenAccountAddress) => {
  const request = {
    "jsonrpc": "2.0",
    "id": 2,
    "method": "accountSubscribe",
    "params": [
      tokenAccountAddress,
      {
        "encoding": "jsonParsed",
        "commitment": "confirmed"
      }
    ]
  };
  
  ws.send(JSON.stringify(request));
};

ws.onmessage = (event) => {
  const data = JSON.parse(event.data);
  
  if (data.method === "accountNotification") {
    const accountData = data.params.result.value.data;
    
    if (accountData.program === "spl-token") {
      const parsed = accountData.parsed;
      console.log(`Token balance: ${parsed.info.tokenAmount.uiAmount}`);
      console.log(`Owner: ${parsed.info.owner}`);
    }
  }
};

程序活动监控

监控由程序拥有的所有账户 - 非常适合监控 DEX 交易、NFT 转移或 DeFi 活动。

// Monitor Raydium AMM for all trade activity
const RAYDIUM_AMM_PROGRAM = "675kPX9MHTjS2zt1qfr1NYHuzeLXfQM9H24wFSUt1Mp8";

const subscribeToProgram = (programId) => {
  const request = {
    "jsonrpc": "2.0",
    "id": 3,
    "method": "programSubscribe",
    "params": [
      programId,
      {
        "encoding": "jsonParsed",
        "commitment": "confirmed",
        "filters": [
          {
            "dataSize": 752 // Raydium pool account size
          }
        ]
      }
    ]
  };
  
  ws.send(JSON.stringify(request));
};

ws.onmessage = (event) => {
  const data = JSON.parse(event.data);
  
  if (data.method === "programNotification") {
    console.log("Raydium pool updated:", data.params.result.value.pubkey);
    // Process the pool data change
    const accountData = data.params.result.value.account;
    // Parse and handle the pool state change
  }
};

subscribeToProgram(RAYDIUM_AMM_PROGRAM);

// Monitor Magic Eden program for NFT activity
const MAGIC_EDEN_PROGRAM = "M2mx93ekt1fmXSVkTrUL9xVFHkmME8HTUi5Cyc5aF7K";

const subscribeToNFTActivity = () => {
  const request = {
    "jsonrpc": "2.0",
    "id": 4,
    "method": "programSubscribe",
    "params": [
      MAGIC_EDEN_PROGRAM,
      {
        "encoding": "base64",
        "commitment": "confirmed"
      }
    ]
  };
  
  ws.send(JSON.stringify(request));
};

ws.onmessage = (event) => {
  const data = JSON.parse(event.data);
  
  if (data.method === "programNotification") {
    console.log("NFT marketplace activity detected");
    // Decode and process the marketplace instruction
    const accountInfo = data.params.result.value;
    // Handle NFT listing, purchase, or cancellation
  }
};

交易监控

跟踪特定交易或监控提及特定账户的交易。

// Monitor a specific transaction signature
const trackTransaction = (signature) => {
  const request = {
    "jsonrpc": "2.0",
    "id": 5,
    "method": "signatureSubscribe",
    "params": [
      signature,
      {
        "commitment": "confirmed"
      }
    ]
  };
  
  ws.send(JSON.stringify(request));
};

ws.onmessage = (event) => {
  const data = JSON.parse(event.data);
  
  if (data.method === "signatureNotification") {
    const result = data.params.result;
    
    if (result.value.err) {
      console.log("Transaction failed:", result.value.err);
    } else {
      console.log("Transaction confirmed successfully!");
    }
    
    // Subscription automatically ends after notification
  }
};

// Track a payment or swap transaction
trackTransaction("YOUR_TRANSACTION_SIGNATURE_HERE");

// Monitor all transactions mentioning a specific address
const monitorAddress = (address) => {
  const request = {
    "jsonrpc": "2.0",
    "id": 6,
    "method": "logsSubscribe",
    "params": [
      {
        "mentions": [address]
      },
      {
        "commitment": "confirmed"
      }
    ]
  };
  
  ws.send(JSON.stringify(request));
};

ws.onmessage = (event) => {
  const data = JSON.parse(event.data);
  
  if (data.method === "logsNotification") {
    const logs = data.params.result.value.logs;
    const signature = data.params.result.value.signature;
    
    console.log(`Transaction ${signature} mentioned our address`);
    console.log("Logs:", logs);
    
    // Parse logs for specific events or errors
    if (logs.some(log => log.includes("Program failed"))) {
      console.log("Transaction failed!");
    }
  }
};

// Monitor a token mint for all activity
monitorAddress("EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v");

生产就绪的实现

这是一个具有重连逻辑、错误处理和适当状态管理的健壮的WebSocket实现：

class WebSocketManager {
  constructor(endpoint) {
    this.endpoint = endpoint;
    this.ws = null;
    this.subscriptions = new Map();
    this.isConnected = false;
  }

  async connect() {
    this.ws = new WebSocket(this.endpoint);
    
    this.ws.onopen = () => {
      console.log('Connected');
      this.isConnected = true;
      this.resubscribeAll();
    };

    this.ws.onmessage = (event) => {
      const data = JSON.parse(event.data);
      
      // Handle subscription confirmations
      if (data.result && typeof data.result === 'number') {
        const sub = Array.from(this.subscriptions.values())
          .find(s => s.requestId === data.id);
        if (sub) sub.subscriptionId = data.result;
        return;
      }

      // Handle notifications
      if (data.method?.endsWith('Notification')) {
        const sub = Array.from(this.subscriptions.values())
          .find(s => s.subscriptionId === data.params.subscription);
        if (sub?.callback) sub.callback(data.params.result);
      }
    };

    this.ws.onclose = () => {
      console.log('Disconnected');
      this.isConnected = false;
      // Implement reconnection logic here
    };
  }

  subscribe(method, params, callback) {
    const requestId = Date.now();
    const subscription = { requestId, method, params, callback, subscriptionId: null };
    this.subscriptions.set(requestId, subscription);
    
    if (this.isConnected) {
      this.ws.send(JSON.stringify({
        jsonrpc: '2.0',
        id: requestId,
        method,
        params
      }));
    }
    
    return requestId;
  }

  resubscribeAll() {
    for (const [id, sub] of this.subscriptions) {
      sub.subscriptionId = null;
      this.ws.send(JSON.stringify({
        jsonrpc: '2.0',
        id,
        method: sub.method,
        params: sub.params
      }));
    }
  }
}

// Usage
const wsManager = new WebSocketManager('wss://mainnet.helius-rpc.com/?api-key=YOUR_API_KEY');
await wsManager.connect();

// Subscribe to account changes
wsManager.subscribe(
  'accountSubscribe',
  ['account-address-here', { commitment: 'confirmed' }],
  (data) => console.log('Account updated:', data)
);

连接管理
内存管理

// Use connection pooling for multiple subscriptions
class WebSocketPool {
  constructor(endpoint, maxConnections = 3) {
    this.endpoint = endpoint;
    this.connections = [];
    this.maxConnections = maxConnections;
    this.currentConnectionIndex = 0;
  }
  
  async getConnection() {
    if (this.connections.length < this.maxConnections) {
      const wsManager = new SolanaWebSocketManager(this.endpoint);
      await wsManager.connect();
      this.connections.push(wsManager);
      return wsManager;
    }
    
    // Round-robin selection
    const connection = this.connections[this.currentConnectionIndex];
    this.currentConnectionIndex = (this.currentConnectionIndex + 1) % this.connections.length;
    return connection;
  }
}

// Implement subscription cleanup and memory management
class ManagedWebSocket extends SolanaWebSocketManager {
  constructor(endpoint, options = {}) {
    super(endpoint, options);
    this.maxSubscriptions = options.maxSubscriptions || 100;
    this.subscriptionHistory = [];
  }
  
  subscribe(method, params, callback) {
    // Check subscription limit
    if (this.subscriptions.size >= this.maxSubscriptions) {
      this.cleanupOldSubscriptions();
    }
    
    const requestId = super.subscribe(method, params, callback);
    
    // Track subscription for cleanup
    this.subscriptionHistory.push({
      requestId,
      timestamp: Date.now(),
      method
    });
    
    return requestId;
  }
  
  cleanupOldSubscriptions() {
    // Remove oldest 10% of subscriptions
    const toRemove = Math.floor(this.subscriptions.size * 0.1);
    const sortedHistory = this.subscriptionHistory
      .sort((a, b) => a.timestamp - b.timestamp);
    
    for (let i = 0; i < toRemove && i < sortedHistory.length; i++) {
      const sub = sortedHistory[i];
      this.unsubscribe(sub.requestId);
      
      // Remove from history
      this.subscriptionHistory = this.subscriptionHistory
        .filter(s => s.requestId !== sub.requestId);
    }
  }
}

错误处理和调试

对于生产中的WebSocket应用程序，健全的错误处理至关重要。实施这些模式以优雅地处理网络问题、速率限制和API错误。

class ErrorHandlingWebSocket extends SolanaWebSocketManager {
  constructor(endpoint, options = {}) {
    super(endpoint, options);
    this.errorCounts = new Map();
    this.maxErrorsPerMinute = options.maxErrorsPerMinute || 10;
  }

  handleMessage(data) {
    try {
      // Handle rate limiting
      if (data.error && data.error.code === 429) {
        console.warn('Rate limited, backing off...');
        this.handleRateLimit();
        return;
      }

      // Handle subscription errors
      if (data.error && data.error.code === -32602) {
        console.error('Invalid subscription parameters:', data.error.message);
        this.handleInvalidSubscription(data.id);
        return;
