Java调用接口示例

• Java调用（原生）

GET请求

public static void main(String[] args) throws Exception {
        // 认证参数
        String appKey ="129faad0fa8a4e0e9bc27e45bbb68d49";      // key
        String appSecret = "ef8f295ed7b342d886ace2e15e14c289";  // 密钥
        long timeStamp = Instant.now().toEpochMilli();   // 时间戳毫秒级

        // 1. 创建 HttpClient
        HttpClient client = HttpClient.newHttpClient();

        // 2. 构建带 Query 参数的 URL
        String url = "https://demo.com/api/web/v1/user/list";
        String query = "apiId=10000";
        URI uri = URI.create(url + "?" + query); // 手动拼接 Query 参数

        // 3. 加密
        String data = appSecret + timeStamp;   // 直接拼接待加密内容
        String sign = SM3Util.hash(data);

        // 4. 创建请求并添加 Headers
        HttpRequest request = HttpRequest.newBuilder()
                .uri(uri)
                .GET()
                .header("Content-Type", "application/json")
                .header("appkey", appKey)
                .header("timestamp", timeStamp+"")
                .header("sign", sign)
                .build();

        // 5. 发送请求并获取响应
        HttpResponse<String> response = client.send(
                request, HttpResponse.BodyHandlers.ofString()
        );

        System.out.println("Response Body: " + response.body());
    }

POST请求

public static void main(String[] args) throws Exception {
        // 认证参数
        String appKey ="129faad0fa8a4e0e9bc27e45bbb68d49";      // key
        String appSecret = "ef8f295ed7b342d886ace2e15e14c289";  // 密钥
        long timeStamp = Instant.now().toEpochMilli();   // 时间戳毫秒级

        // 1. 创建 HttpClient
        HttpClient client = HttpClient.newHttpClient();

        // 2. 构建 JSON 请求体
        String jsonBody = "{}";

        // 3. 加密
        String data = appSecret + timeStamp;   // 直接拼接待加密内容
        String sign = SM3Util.hash(data);

        // 4. 创建请求并添加 Headers
        HttpRequest request = HttpRequest.newBuilder()
                .uri(URI.create("https://demo.com/api/web/v1/user"))
                .POST(HttpRequest.BodyPublishers.ofString(jsonBody))
                .header("Content-Type", "application/json")
                .header("appkey", appKey)
                .header("timestamp", timeStamp+"")
                .header("sign", sign)
                .build();

        // 5. 发送请求并获取响应
        HttpResponse<String> response = client.send(
                request, HttpResponse.BodyHandlers.ofString()
        );

        System.out.println("Response Body: " + response.body());
    }

• Java调用（Okhttp）

OkHttpClient client = new OkHttpClient().newBuilder().build();
MediaType mediaType = MediaType.parse("application/json");
RequestBody body = RequestBody.create(mediaType, "{\"id\": 1}");
Request request = new Request.Builder()
  .url("http://127.0.0.1/api/web/user/list")
  .method("POST",body)
  .addHeader("appkey","你的应用appKey")
  .addHeader("timestamp","时间戳")
  .addHeader("sign","签名加密串")
  .addHeader("Content-Type","")
  .build();

Response response = client.newCall(request).execute();
