Java 实现视频下载功能
public static boolean httpDownload(String httpUrl, String saveFile) { // 1.下载网络文件 int byteRead; URL url; try { url = new URL(httpUrl); } catch (MalformedURLException e1) { e1.printStackTrace(); return false; } try { //2.获取链接 URLConnection conn = url.openConnection(); //3.输入流 InputStream inStream = conn.getInputStream(); //3.写入文件 FileOutputStream fs = new FileOutputStream(saveFile); byte[] buffer = new byte[1024]; while ((byteRead = inStream.read(buffer)) != -1) { fs.write(buffer, 0, byteRead); } inStream.close(); fs.close(); return true; } catch (FileNotFoundException e) { e.printStackTrace(); return false; } catch (IOException e) { e.printStackTrace(); return false; } } @Test public void httpDownload() { httpDownload("http://video.zhihuishu.com/zhs/ablecommons/demo/201806/dddee1c446314b84a26c74a8def3c3c7.mp4","E:\\test/22.mp4"); }
前提需要:加载servlet容器,不能使用main方法直接调用
