java通过Jsoup爬取下载抖音无水印视频(下载单个抖音视频)

您好，可以使用Java中的HttpClient库和Jsoup库来实现爬取视频并下载到本地的功能。具体实现步骤如下： 1. 使用HttpClient库发送HTTP请求，获取视频的URL地址。 2. 使用Jsoup库解析HTML页面，获取视频的URL地址。 3. 使用Java中的IO流将视频文件下载到本地。 以下是示例代码： ```java import java.io.FileOutputStream; import java.io.InputStream; import java.net.HttpURLConnection; import java.net.URL; import org.apache.http.HttpEntity; import org.apache.http.client.methods.CloseableHttpResponse; import org.apache.http.client.methods.HttpGet; import org.apache.http.impl.client.CloseableHttpClient; import org.apache.http.impl.client.HttpClients; import org.jsoup.Jsoup; import org.jsoup.nodes.Document; import org.jsoup.nodes.Element; public class VideoDownloader { public static void main(String[] args) throws Exception { String url="https://www.example.com/video.html"; String videoUrl=getVideoUrl(url); downloadVideo(videoUrl, "video.mp4"); } public static String getVideoUrl(String url) throws Exception { CloseableHttpClient httpClient=HttpClients.createDefault(); HttpGet httpGet=new HttpGet(url); CloseableHttpResponse response=httpClient.execute(httpGet); HttpEntity entity=response.getEntity(); InputStream inputStream=entity.getContent(); Document document=Jsoup.parse(inputStream, "UTF-8", url); Element videoElement=document.select("video").first(); String videoUrl=videoElement.attr("src"); response.close(); return videoUrl; } public static void downloadVideo(String videoUrl, String fileName) throws Exception { URL url=new URL(videoUrl); HttpURLConnection connection=(HttpURLConnection) url.openConnection(); connection.setRequestMethod("GET"); connection.setConnectTimeout(5000); InputStream inputStream=connection.getInputStream(); FileOutputStream outputStream=new FileOutputStream(fileName); byte[] buffer=new byte[1024]; int len; while ((len=inputStream.read(buffer)) !=-1) { outputStream.write(buffer, 0, len); } outputStream.close(); inputStream.close(); } } ``` 请注意，此代码仅供参考，具体实现可能因网站结构和视频格式而异。
