java上传下载视频的代码

以下是Java实现上传下载视频的示例代码：

上传视频：

File file = new File("video.mp4"); //本地视频文件
String url = "http://example.com/upload"; //上传接口地址

CloseableHttpClient httpClient = HttpClients.createDefault();
HttpPost httpPost = new HttpPost(url);

//设置请求实体为文件实体
FileEntity fileEntity = new FileEntity(file, ContentType.DEFAULT_BINARY);
httpPost.setEntity(fileEntity);

//发送请求并获取响应
CloseableHttpResponse response = httpClient.execute(httpPost);
response.close();
httpClient.close();

下载视频：

String url = "http://example.com/video.mp4"; //下载视频地址

CloseableHttpClient httpClient = HttpClients.createDefault();
HttpGet httpGet = new HttpGet(url);

//发送请求并获取响应
CloseableHttpResponse response = httpClient.execute(httpGet);
HttpEntity entity = response.getEntity();
InputStream inputStream = entity.getContent();

//将响应内容写入本地文件
FileOutputStream fileOutputStream = new FileOutputStream("video.mp4"); //本地文件名
byte[] buffer = new byte[1024];
int len;
while ((len = inputStream.read(buffer)) != -1) {
    fileOutputStream.write(buffer, 0, len);
}

fileOutputStream.close();
inputStream.close();
response.close();
httpClient.close();

这段代码使用Apache HttpComponents库实现，需要在项目中引入httpclient和httpcore两个包。
