如何将从HTTP GET响应中获取的文件保存到磁盘文件java中

URL url = new URL("http://example.com/file.txt"); // 替换为实际的文件URL
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("GET");

int responseCode = connection.getResponseCode();
if (responseCode == HttpURLConnection.HTTP_OK) {
    // 获取输入流
    InputStream inputStream = connection.getInputStream();
    
    // 创建输出流，用于保存文件
    FileOutputStream outputStream = new FileOutputStream("path/to/save/file.txt"); // 替换为实际的保存路径
    
    // 读取输入流中的数据，并写入输出流中保存到文件
    byte[] buffer = new byte[4096];
    int bytesRead;
    while ((bytesRead = inputStream.read(buffer)) != -1) {
        outputStream.write(buffer, 0, bytesRead);
    }
    
    // 关闭输入流和输出流
    outputStream.close();
    inputStream.close();
} else {
    // 处理响应错误
}
