根据 StockTV 文档,美股数据同样属于「全球股票」模块。下面我用 Java 给出一套可测试、可扩展的美股对接方案,重点解决 countryId不确定的问题。
一、基础配置 & 通用工具类
import com.fasterxml.jackson.databind.ObjectMapper;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;
import java.io.IOException;
import java.net.URLEncoder;
import java.nio.charset.StandardCharsets;
import java.util.HashMap;
import java.util.Map;
public class StockTVUSClient {
public static final String BASE_URL = "https://api.stocktv.top";
public static final String API_KEY = "你的_API_KEY"; // 🔴 替换成你的 key
public static final int US_COUNTRY_ID = 5; // 已确认的美国 countryId
private static final ObjectMapper mapper = new ObjectMapper();
// 通用 GET 请求
public static String get(String path, Map<String, String> params) throws IOException {
Map<String, String> fullParams = new HashMap<>(params);
fullParams.put("key", API_KEY);
StringBuilder url = new StringBuilder(BASE_URL + path);
if (!fullParams.isEmpty()) {
url.append("?");
for (Map.Entry<String, String> e : fullParams.entrySet()) {
url.append(e.getKey())
.append("=")
.append(URLEncoder.encode(e.getValue(), StandardCharsets.UTF_8))
.append("&");
}
url.deleteCharAt(url.length() - 1); // 去掉末尾 &
}
try (CloseableHttpClient client = HttpClients.createDefault()) {
HttpGet req = new HttpGet(url.toString());
try (CloseableHttpResponse resp = client.execute(req)) {
return EntityUtils.toString(resp.getEntity());
}
}
}
// 解析 JSON
public static <T> T parse(String json, Class<T> clazz) throws IOException {
return mapper.readValue(json, clazz);
}
}
二、数据模型(共用一套,适合所有国家)
import com.fasterxml.jackson.annotation.JsonProperty;
import java.util.List;
// 股票列表响应
class StockListResponse {
@JsonProperty("code") int code;
@JsonProperty("message") String message;
@JsonProperty("data") Data data;
static class Data {
@JsonProperty("records") List<Stock> records;
@JsonProperty("total") int total;
}
static class Stock {
@JsonProperty("id") Long id; // PID,用于 K 线和订阅
@JsonProperty("name") String name;
@JsonProperty("symbol") String symbol; // 如 AAPL
@JsonProperty("last") Double last;
@JsonProperty("chg") Double chg;
@JsonProperty("chgPct") Double chgPct;
@JsonProperty("high") Double high;
@JsonProperty("low") Double low;
@JsonProperty("volume") Long volume;
@JsonProperty("open") Boolean open; // 是否开盘
@JsonProperty("countryId") Integer countryId;
@JsonProperty("flag") String flag; // US
}
}
// K 线响应
class KlineResponse {
@JsonProperty("code") int code;
@JsonProperty("message") String message;
@JsonProperty("data") List<KlineBar> data;
static class KlineBar {
@JsonProperty("time") Long time; // 毫秒时间戳
@JsonProperty("open") Double open;
@JsonProperty("high") Double high;
@JsonProperty("low") Double low;
@JsonProperty("close") Double close;
@JsonProperty("volume") Double volume;
}
}
// 指数响应
class IndexResponse {
@JsonProperty("code") int code;
@JsonProperty("message") String message;
@JsonProperty("data") List<Index> data;
static class Index {
@JsonProperty("id") Long id;
@JsonProperty("name") String name; // 如 "S&P 500"
@JsonProperty("symbol") String symbol; // 如 SPX
@JsonProperty("last") Double last;
@JsonProperty("chgPct") Double chgPct;
@JsonProperty("flag") String flag; // US
}
}
三、美股核心接口封装
import java.io.IOException;
import java.util.Map;
public class USStockAPI {
private static final int US_ID = StockTVUSClient.US_COUNTRY_ID;
// 1. 获取美股列表(支持分页)
public static StockListResponse listStocks(int page, int pageSize) throws IOException {
Map<String, String> params = Map.of(
"countryId", String.valueOf(US_ID),
"page", String.valueOf(page),
"pageSize", String.valueOf(pageSize)
);
String json = StockTVUSClient.get("/stock/stocks", params);
return StockTVUSClient.parse(json, StockListResponse.class);
}
// 2. 按 symbol 查询(如 "AAPL")
public static StockListResponse queryBySymbol(String symbol) throws IOException {
Map<String, String> params = Map.of("symbol", symbol);
String json = StockTVUSClient.get("/stock/queryStocks", params);
return StockTVUSClient.parse(json, StockListResponse.class);
}
// 3. 获取 K 线(需要 PID)
public static KlineResponse getKline(long pid, String interval) throws IOException {
Map<String, String> params = Map.of(
"pid", String.valueOf(pid),
"interval", interval
);
String json = StockTVUSClient.get("/stock/kline", params);
return StockTVUSClient.parse(json, KlineResponse.class);
}
// 4. 获取美股大盘指数
public static IndexResponse getIndices() throws IOException {
Map<String, String> params = Map.of("countryId", String.valueOf(US_ID));
String json = StockTVUSClient.get("/stock/indices", params);
return StockTVUSClient.parse(json, IndexResponse.class);
}
}
四、使用示例:跑一遍完整流程
import java.io.IOException;
import java.text.SimpleDateFormat;
import java.util.Date;
public class USExample {
public static void main(String[] args) throws IOException {
// 1. 拉第一页美股列表
StockListResponse listResp = USStockAPI.listStocks(1, 10);
if (listResp.code != 200) {
System.out.println("❌ 列表请求失败: " + listResp.message);
return;
}
System.out.println("📊 美股列表(前10只):");
for (StockListResponse.Stock s : listResp.data.records) {
System.out.printf("- %s (%s) %.2f 涨跌: %.2f%%\n",
s.name, s.symbol, s.last, s.chgPct);
}
// 2. 查一只具体的票(比如 Apple)
StockListResponse aaplResp = USStockAPI.queryBySymbol("AAPL");
if (aaplResp.code == 200 && !aaplResp.data.records.isEmpty()) {
StockListResponse.Stock aapl = aaplResp.data.records.get(0);
System.out.println("\n🍎 Apple 信息: PID=" + aapl.id + ", 当前价=" + aapl.last);
// 3. 拿日 K 线
KlineResponse kline = USStockAPI.getKline(aapl.id, "P1D");
if (kline.code == 200 && !kline.data.isEmpty()) {
KlineResponse.KlineBar latest = kline.data.get(kline.data.size() - 1);
String date = new SimpleDateFormat("yyyy-MM-dd")
.format(new Date(latest.time));
System.out.printf("最近日K: %s O:%.2f H:%.2f L:%.2f C:%.2f\n",
date, latest.open, latest.high, latest.low, latest.close);
}
}
// 4. 大盘指数
IndexResponse indices = USStockAPI.getIndices();
if (indices.code == 200) {
System.out.println("\n📈 美股指数:");
for (IndexResponse.Index idx : indices.data) {
System.out.printf("- %s (%s): %.2f %.2f%%\n",
idx.name, idx.symbol, idx.last, idx.chgPct);
}
}
}
}
五、实时数据(WebSocket 版)
import org.java_websocket.client.WebSocketClient;
import org.java_websocket.handshake.ServerHandshake;
import org.json.JSONObject;
import java.net.URI;
import java.util.List;
import java.util.Timer;
import java.util.TimerTask;
public class USWebSocketClient extends WebSocketClient {
private static final String WS_URL =
"wss://ws-api.stocktv.top/connect?key=" + StockTVUSClient.API_KEY;
public USWebSocketClient() {
super(URI.create(WS_URL));
}
@Override
public void onOpen(ServerHandshake h) {
System.out.println("✅ 美股实时连接已打开");
}
@Override
public void onMessage(String msg) {
JSONObject data = new JSONObject(msg);
String pid = data.getString("pid");
String price = data.getString("last_numeric");
String change = data.getString("pc");
String pct = data.getString("pcp");
System.out.printf("[实时] PID=%s 价格=%s 涨跌=%s(%s%%)\n", pid, price, change, pct);
}
@Override
public void onClose(int code, String reason, boolean remote) {
System.out.println("❌ 连接关闭: " + reason);
}
@Override
public void onError(Exception e) {
e.printStackTrace();
}
// 订阅美股 PID 列表
public void subscribe(List<Long> pids) {
if (!isOpen()) return;
JSONObject sub = new JSONObject();
sub.put("action", "subscribe");
sub.put("pids", pids);
send(sub.toString());
System.out.println("已订阅: " + pids);
}
// 简单心跳(每30秒发空消息)
public void startHeartbeat() {
new Timer(true).scheduleAtFixedRate(new TimerTask() {
@Override
public void run() {
if (isOpen()) send("");
}
}, 0, 30000);
}
}
六、快速上手步骤
- 把
API_KEY换成你从 StockTV 客服那里拿到的 key; - 直接运行
USExample.main(),看能否正常输出美股列表、指数、K 线; - 如果有真实的 PID(比如 AAPL 的 PID),再用
USWebSocketClient订阅实时行情。
这套代码完全适配 countryId=5,你只需要关心填入正确 PID 和 API Key 即可正常使用。
