java通过路径返回流给前台

 还没有测试

String data = "Hello, World!"; // 要发送的数据
        String url = "http://example.com/stream"; // 前台的URL地址

        try {
            // 创建一个URL对象并连接到前台的URL地址
            URL urlObj = new URL(url);
            HttpURLConnection conn = (HttpURLConnection) urlObj.openConnection();

            // 设置请求方式和响应类型
            conn.setRequestMethod("POST");
            conn.setDoOutput(true);
            conn.setContentType("application/octet-stream");

            // 获取输入流并写入数据
            OutputStream outputStream = conn.getOutputStream();
            outputStream.write(data.getBytes());
            outputStream.flush();
            outputStream.close();

            // 获取响应码并输出结果
            int responseCode = conn.getResponseCode();
            System.out.println("Response Code: " + responseCode);

            conn.disconnect();
