springboot接入方式对接股票数据源API接口

技术分享 11个月前 (03-03) 0 999+

为了创建一个Java项目来对接StockTV的API接口，我们可以使用HttpURLConnection或第三方库如OkHttp来发送HTTP请求，并使用Java-WebSocket库来处理WebSocket连接。以下是一个简单的Java项目结构，展示了如何对接这些API接口。

项目结构

1. 添加依赖

在pom.xml中添加以下依赖：

<dependencies>     <!-- OkHttp for HTTP requests -->     <dependency>         <groupId>com.squareup.okhttp3</groupId>         <artifactId>okhttp</artifactId>         <version>4.9.3</version>     </dependency>      <!-- Java-WebSocket for WebSocket connections -->     <dependency>         <groupId>org.java-websocket</groupId>         <artifactId>Java-WebSocket</artifactId>         <version>1.5.2</version>     </dependency>      <!-- Gson for JSON parsing -->     <dependency>         <groupId>com.google.code.gson</groupId>         <artifactId>gson</artifactId>         <version>2.8.9</version>     </dependency>      <!-- JUnit for testing -->     <dependency>         <groupId>org.junit.jupiter</groupId>         <artifactId>junit-jupiter-api</artifactId>         <version>5.8.1</version>         <scope>test</scope>     </dependency>     <dependency>         <groupId>org.junit.jupiter</groupId>         <artifactId>junit-jupiter-engine</artifactId>         <version>5.8.1</version>         <scope>test</scope>     </dependency> </dependencies>

2. 创建基础工具类

在src/main/java/com/stocktv/api/utils/ApiUtils.java中，创建一个基础工具类来处理API请求：

package com.stocktv.api.utils;  import com.google.gson.Gson; import okhttp3.OkHttpClient; import okhttp3.Request; import okhttp3.Response;  import java.io.IOException;  public class ApiUtils {     private static final String BASE_URL = "https://api.stocktv.top";     private static final OkHttpClient client = new OkHttpClient();     private static final Gson gson = new Gson();      private String apiKey;      public ApiUtils(String apiKey) {         this.apiKey = apiKey;     }      public String get(String endpoint, String queryParams) throws IOException {         String url = BASE_URL + "/" + endpoint + "?key=" + apiKey + (queryParams != null ? "&" + queryParams : "");         Request request = new Request.Builder()                 .url(url)                 .build();          try (Response response = client.newCall(request).execute()) {             if (!response.isSuccessful()) throw new IOException("Unexpected code " + response);             return response.body().string();         }     }      public <T> T get(String endpoint, String queryParams, Class<T> responseType) throws IOException {         String json = get(endpoint, queryParams);         return gson.fromJson(json, responseType);     } }

6. 实现加密货币API

在src/main/java/com/stocktv/api/CryptoAPI.java中，实现加密货币相关的API：

package com.stocktv.api;  import com.stocktv.api.utils.ApiUtils;  public class CryptoAPI {     private ApiUtils apiUtils;      public CryptoAPI(String apiKey) {         this.apiUtils = new ApiUtils(apiKey);     }      public String getCoinInfo() throws IOException {         return apiUtils.get("crypto/getCoinInfo", null);     }      public String getCoinList(int start, int limit) throws IOException {         String queryParams = "start=" + start + "&limit=" + limit;         return apiUtils.get("crypto/getCoinList", queryParams);     }      public String getTickerPrice(String symbols) throws IOException {         String queryParams = "symbols=" + symbols;         return apiUtils.get("crypto/tickerPrice", queryParams);     }      public String getLastPrice(String symbols) throws IOException {         String queryParams = "symbols=" + symbols;         return apiUtils.get("crypto/lastPrice", queryParams);     }      public String getKlines(String symbol, String interval) throws IOException {         String queryParams = "symbol=" + symbol + "&interval=" + interval;         return apiUtils.get("crypto/getKlines", queryParams);     }      public String getTrades(String symbol) throws IOException {         String queryParams = "symbol=" + symbol;         return apiUtils.get("crypto/getTrades", queryParams);     } }

7. 测试代码

在src/test/java/com/stocktv/api/StockAPITest.java中，编写测试代码来验证股票API的功能：

package com.stocktv.api;  import org.junit.jupiter.api.BeforeEach; import org.junit.jupiter.api.Test; import static org.junit.jupiter.api.Assertions.*;  public class StockAPITest {     private StockAPI stockAPI;      @BeforeEach     public void setUp() {         String apiKey = "your_api_key_here";         stockAPI = new StockAPI(apiKey);     }      @Test     public void testGetStockList() throws Exception {         String response = stockAPI.getStockList(14, 10, 1);         assertNotNull(response);         System.out.println(response);     }      @Test     public void testGetIndices() throws Exception {         String response = stockAPI.getIndices(14, null);         assertNotNull(response);         System.out.println(response);     }      @Test     public void testGetKline() throws Exception {         String response = stockAPI.getKline(7310, "PT1M");         assertNotNull(response);         System.out.println(response);     } }

8. 运行测试

使用以下命令运行测试：

mvn test

9. 编写README.md

最后，编写一个README.md文件，描述项目的用途、安装步骤和使用方法。
