如何通过B站视频AV号找到弹幕对应的xml文件号
首先爬取视频网页，将对应视频网页源码获得
就可以找到该视频的av号aid=8678034
还有弹幕序号，cid=14295428
弹幕存放位置为 http://comment.bilibili.com/14295428.xml
获得该链接内容即可。
1 package BiliBili弹幕爬取; 2 3 import org.apache.http.HttpEntity; 4 import org.apache.http.client.methods.CloseableHttpResponse; 5 import org.apache.http.client.methods.HttpGet; 6 import org.apache.http.impl.client.CloseableHttpClient; 7 import org.apache.http.impl.client.HttpClients; 8 import org.apache.http.util.EntityUtils; 9 10 import java.util.regex.Matcher; 11 import java.util.regex.Pattern; 12 13 public class getBiliBiliBofqi { 14 public static void getBofqi(String aid) throws Exception{ 15 CloseableHttpClient closeableHttpClient = HttpClients.createDefault() ; 16 HttpGet httpGet = new HttpGet("https://www.bilibili.com/video/av"+aid+"/") ; 17 CloseableHttpResponse httpResponse = closeableHttpClient.execute(httpGet) ; 18 HttpEntity httpEntity = httpResponse.getEntity() ; 19 String en= EntityUtils.toString(httpEntity) ; 20 //"cid=16496518&aid=9979006&pre_ad=" 21 String con = "cid=(.*)?&aid=" ; 22 Pattern ah = Pattern.compile(con); 23 Matcher mr = ah.matcher(en); 24 while(mr.find()) { 25 String id = mr.group() ; 26 String newUrl = id.replace("cid=","") ; 27 String x = newUrl.replace("&aid=","") ; 28 HttpGet httpGet1 = new HttpGet("http://comment.bilibili.com/"+x+".xml"); 29 CloseableHttpResponse httpResponse1 = closeableHttpClient.execute(httpGet1) ; 30 HttpEntity httpEntity1 = httpResponse1.getEntity() ; 31 String en1 = EntityUtils.toString(httpEntity1) ; 32 String c = "\">(.*?)<" ; 33 Pattern a = Pattern.compile(c); 34 Matcher m = a.matcher(en1); 35 while(m.find()){ 36 String speak = m.group().replace("\">","") ; 37 speak = speak.replace("<","") ; 38 System.out.println(speak); 39 } 40 } 41 } 42 public static void main(String[] args) throws Exception{ 43 getBofqi("8678034"); 44 } 45 }
