  public static String getWxAppDataSign(String appId, String secretKey, String timestamp, String startTime, String endTime) {

    String signStr = String.format(TencentMobileConstant.SIGN_TEMPLATE, secretKey, appId, endTime, startTime, timestamp);
    String sign = "";
    try {
      MessageDigest md = MessageDigest.getInstance("MD5");
      md.update(signStr.getBytes());
      byte[] resultByteArray = md.digest();
      sign = new BigInteger(1, resultByteArray).toString(16);
    } catch (Exception e) {
      e.printStackTrace();
    }
    return sign;
  }

2. test

  public static void main(String[] args) {
    String appId = "xxxx"; // 你的小程序appId
    String secretKey = "xxxxxxxxxxxxxxxxxxxxx"; // 你的小程序secretKey
    long a = Calendar.getInstance().getTimeInMillis();
    String timestamp = String.valueOf(a/1000);	// 秒
    String startTime = "2019-12-20";
    String endTime = "2019-12-20";
    String sign = getWxAppDataSign(appId, secretKey, timestamp, startTime,endTime);
  }

After acquiring signature, get access request https://openapi.mta.qq.com/wx/v1/analytics/period?start_time=2019-12-20&end_time=2019-12-20&timestamp=1576808602&app_id=xxxx&sign=3a26dd3d76bcb12d2a55fe253995exxx, to obtain the data.
