用HttpClient写一个获取视频流的请求方法

以下是一个使用HttpClient获取视频流的示例代码：

import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;

import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;

public class VideoStreamHttpClient {

    public static void main(String[] args) throws IOException {
        String url = "http://example.com/video.mp4";
        String outputFilePath = "video.mp4";

        CloseableHttpClient httpClient = HttpClients.createDefault();

        HttpGet httpGet = new HttpGet(url);

        try {
            InputStream inputStream = httpClient.execute(httpGet).getEntity().getContent();
            FileOutputStream outputStream = new FileOutputStream(outputFilePath);

            byte[] buffer = new byte[4096];
            int bytesRead;
            while ((bytesRead = inputStream.read(buffer)) != -1) {
                outputStream.write(buffer, 0, bytesRead);
            }

            outputStream.flush();
            outputStream.close();
            inputStream.close();

            System.out.println("Video stream saved to " + outputFilePath);
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            httpClient.close();
        }
    }
}

这个示例代码使用HttpClient发送了一个GET请求来获取视频流，并将其保存到本地文件中。需要修改`url`和`outputFilePath`变量以适应你的情况。注意，这个示例代码并没有处理HTTP响应的状态码和错误信息，实际应用中需要根据需要进行相应的处理。
