提取视频
分离网址获取Bvid
网址https://www.bilibili.com/video/BV1M9XeYJE7V/?spm_id_from=333.1007.tianma.1-1-1.click&vd_source=d5b9a2e757fb051555e941f2124bf792的bvid为
BV1M9XeYJE7V
利用正则表达式
package com.download.bilidown.utils;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class BliApi {
public static String extractBvidFromUrl(String url) {
//构建正则：10位的BV开头的
Pattern pattern = Pattern.compile("(?<=video/|BV)[a-zA-Z0-9]{10}");
Matcher matcher = pattern.matcher(url);
if (matcher.find()) {
String bvid = matcher.group();
return bvid.startsWith("BV") ? bvid : "BV" + bvid;
}
return null;
}
public static void main(String[] args) {
String url1 = "https://www.bilibili.com/video/BV1M9XeYJE7V/?spm_id_from=333.1007.tianma.1-1-1.click&vd_source=d5b9a2e757fb051555e941f2124bf792";
String url2 = "https://b23.tv/BV1GJ411x7h7";
System.out.println(extractBvidFromUrl(url1));
System.out.println(extractBvidFromUrl(url2));
}
}
利用网址路径
import java.net.URI;
import java.net.URISyntaxException;
public class BvidExtractor {
public static String extractBvidFromUrl(String url) throws URISyntaxException {
URI uri = new URI(url);
String path = uri.getPath();
// 从路径中提取BV号
if (path.contains("/video/BV")) {
String[] parts = path.split("/");
for (String part : parts) {
if (part.startsWith("BV") && part.length() == 12) {
return part;
}
}
}
return null;
}
public static void main(String[] args) throws URISyntaxException {
String url = "https://www.bilibili.com/video/BV1M9XeYJE7V/?spm_id_from=333.1007.tianma.1-1-1.click&vd_source=d5b9a2e757fb051555e941f2124bf792";
System.out.println(extractBvidFromUrl(url)); // 输出: BV1GJ411x7h7
}
}
获取Cid
这里我们需要用到一条api链接:https://api.bilibili.com/x/web-interface/view?bvid=
我们将Bvid添加到这条链接末尾进行访问，它会返回一个json文本，其中就包括我们需要的Cid

获取视频原始链接
获取到Bvid和Cid后，我们就可以通过另一条api链接来获取视频原始链接:https://api.bilibili.com/x/player/playurl?otype=json&fnver=0&fnval=2&player=1&qn=64&bvid=Bvid&cid=Cid
将这条链接中的Bvid和Cid换成我们刚刚获取到的，在网页中请求一下，即可获得一个json文本
获取视频播放信息
public JSONObject getVideoPlayInfo(String bvid, String cid) {
try {
// 1. 构建请求URL
String apiUrl = String.format(BliConstant.PLAY_URL_API, bvid, cid);
// 2. 创建HTTP连接
URL url = new URL(apiUrl);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("GET");
connection.setRequestProperty("User-Agent", "Mozilla/5.0");
connection.setRequestProperty("Referer", "https://www.bilibili.com");
// 3. 获取响应
int responseCode = connection.getResponseCode();
if (responseCode == HttpURLConnection.HTTP_OK) {
BufferedReader in = new BufferedReader(
new InputStreamReader(connection.getInputStream()));
String inputLine;
StringBuilder response = new StringBuilder();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
in.close();
// 4. 使用AliJson解析JSON
return JSON.parseObject(response.toString());
} else {
System.err.println("HTTP请求失败，状态码: " + responseCode);
}
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
