如何使用java从http url下载视频文件(视频流链接)？

使用Java从HTTP URL下载视频文件（视频流链接）可以通过以下步骤实现：

1. 导入所需的Java类库：import java.io.BufferedInputStream; import java.io.FileOutputStream; import java.io.IOException; import java.io.InputStream; import java.net.HttpURLConnection; import java.net.URL;
2. 创建一个方法来下载视频文件：public static void downloadVideo(String videoUrl, String savePath) throws IOException { URL url = new URL(videoUrl); HttpURLConnection connection = (HttpURLConnection) url.openConnection(); connection.connect();

   InputStream inputStream = connection.getInputStream();

   BufferedInputStream bufferedInputStream = new BufferedInputStream(inputStream);

   FileOutputStream fileOutputStream = new FileOutputStream(savePath);

   byte[] buffer = new byte[4096];

   int bytesRead;

   while ((bytesRead = bufferedInputStream.read(buffer)) != -1) {

       fileOutputStream.write(buffer, 0, bytesRead);

   }

   fileOutputStream.close();

   bufferedInputStream.close();

   connection.disconnect();

}

1. 调用该方法并传入视频的URL和保存路径：public static void main(String[] args) { String videoUrl = "http://example.com/video.mp4"; String savePath = "path/to/save/video.mp4";

   try {

       downloadVideo(videoUrl, savePath);

       System.out.println("视频下载完成！");

   } catch (IOException e) {

       e.printStackTrace();

   }

}

这样，通过调用downloadVideo方法，你就可以使用Java从HTTP URL下载视频文件了。请确保视频链接是有效的，并提供正确的保存路径。
