复制代码 1. 安装依赖
在项目根目录下运行以下命令初始化项目并安装依赖:- npm init -y
- npm install axios ws
- npm install --save-dev jest
复制代码 2. 创建基础工具类
在 src/ApiClient.js 中,创建一个基础工具类来处理 API 请求:- const axios = require('axios');
- class ApiClient {
- constructor(apiKey) {
- this.apiKey = apiKey;
- this.baseUrl = "https://api.stocktv.top";
- this.client = axios.create({
- baseURL: this.baseUrl,
- timeout: 10000, // 10秒超时
- });
- }
- async get(endpoint, params = {}) {
- try {
- const response = await this.client.get(`/${endpoint}`, {
- params: {
- key: this.apiKey,
- ...params,
- },
- });
- return response.data;
- } catch (error) {
- throw new Error(`API request failed: ${error.message}`);
- }
- }
- }
- module.exports = ApiClient;
复制代码 3. 实现股票 API
在 src/StockAPI.js 中,实现股票相关的 API:- const ApiClient = require('./ApiClient');
- class StockAPI extends ApiClient {
- async getStockList(countryId, pageSize = 10, page = 1) {
- return this.get('stock/stocks', {
- countryId,
- pageSize,
- page,
- });
- }
- async getIndices(countryId, flag = null) {
- const params = { countryId };
- if (flag) params.flag = flag;
- return this.get('stock/indices', params);
- }
- async getKline(pid, interval) {
- return this.get('stock/kline', {
- pid,
- interval,
- });
- }
- }
- module.exports = StockAPI;
复制代码 4. 实现外汇 API
在 src/ForexAPI.js 中,实现外汇相关的 API:- const ApiClient = require('./ApiClient');
- class ForexAPI extends ApiClient {
- async getCurrencyList() {
- return this.get('market/currencyList');
- }
- async getRealTimeRates(countryType = null) {
- const params = {};
- if (countryType) params.countryType = countryType;
- return this.get('market/currency', params);
- }
- }
- module.exports = ForexAPI;
复制代码 5. 实现期货 API
在 src/FuturesAPI.js 中,实现期货相关的 API:- const ApiClient = require('./ApiClient');
- class FuturesAPI extends ApiClient {
- async getFuturesList() {
- return this.get('futures/list');
- }
- async getFuturesMarket(symbol) {
- return this.get('futures/querySymbol', { symbol });
- }
- }
- module.exports = FuturesAPI;
复制代码 6. 实现加密货币 API
在 src/CryptoAPI.js 中,实现加密货币相关的 API:- const ApiClient = require('./ApiClient');
- class CryptoAPI extends ApiClient {
- async getCoinInfo() {
- return this.get('crypto/getCoinInfo');
- }
- async getTickerPrice(symbols) {
- return this.get('crypto/tickerPrice', { symbols });
- }
- }
- module.exports = CryptoAPI;
复制代码 7. WebSocket 支持
使用 ws 库实现 WebSocket 连接:- const WebSocket = require('ws');
- class StockTVWebSocket {
- constructor(apiKey) {
- this.apiKey = apiKey;
- this.wsUrl = `wss://ws-api.stocktv.top/connect?key=${apiKey}`;
- }
- connect() {
- const ws = new WebSocket(this.wsUrl);
- ws.on('open', () => {
- console.log('WebSocket connected');
- });
- ws.on('message', (data) => {
- console.log('Received:', data.toString());
- });
- ws.on('close', () => {
- console.log('WebSocket disconnected');
- });
- ws.on('error', (error) => {
- console.error('WebSocket error:', error);
- });
- }
- }
- module.exports = StockTVWebSocket;
复制代码 8. 测试代码
在 tests/StockAPI.test.js 中,编写测试代码:- const StockAPI = require('../src/StockAPI');
- describe('StockAPI', () => {
- let stockAPI;
- beforeAll(() => {
- stockAPI = new StockAPI('your_api_key_here');
- });
- test('getStockList returns data', async () => {
- const data = await stockAPI.getStockList(14, 10, 1);
- expect(data).toHaveProperty('data');
- });
- });
复制代码 运行测试:9. 使用示例
在 index.js 中,编写示例代码:- const StockAPI = require('./src/StockAPI');
- const StockTVWebSocket = require('./src/StockTVWebSocket');
- const apiKey = 'your_api_key_here';
- // HTTP API 示例
- (async () => {
- const stockAPI = new StockAPI(apiKey);
- try {
- const stockList = await stockAPI.getStockList(14, 10, 1);
- console.log('Stock List:', stockList);
- } catch (error) {
- console.error('Error:', error.message);
- }
- })();
- // WebSocket 示例
- const wsClient = new StockTVWebSocket(apiKey);
- wsClient.connect();
复制代码 10. README.md
在项目根目录下创建 README.md 文件:- # StockTV API Node.js Client
- A Node.js client for accessing StockTV's global financial data APIs.
- ## Installation
- ```bash
- npm install stocktv-api-node
复制代码 Usage
- const StockAPI = require('stocktv-api-node').StockAPI;
- const apiKey = "your_api_key_here";
- const stockAPI = new StockAPI(apiKey);
- (async () => {
- const stockList = await stockAPI.getStockList(14, 10, 1);
- console.log(stockList);
- })();
复制代码 总结
这个 Node.js 项目提供了对 StockTV API 的完整支持,包括股票、外汇、期货和加密货币数据。通过模块化设计和清晰的代码结构,开发者可以轻松扩展和集成到自己的项目中。
