阿里云获取视频资源时长
作者：互联网
阿里云oss授权访问文档示例地址
阿里云没有提供直接的获取是视频时长的API接口，需要曲线处理
1、引入阿里云oss pom
<dependency>
<groupId>com.aliyun.oss</groupId>
<artifactId>aliyun-sdk-oss</artifactId>
<version>3.10.2</version>

阿里云配置类
@Data
public class AliOssPublicEntity {
private String endpoint;
private String accessKeyId;
private String accessKeySecret;
private String bucketName;
private String objectKey;
public static AliOssPublicEntity build(String objectKey,String endpoint,String accessKeyId,
String accessKeySecret,String bucketName) {
AliOssPublicEntity entity = new AliOssPublicEntity();
entity.setEndpoint(endpoint);
entity.setAccessKeyId(accessKeyId);
entity.setAccessKeySecret(accessKeySecret);
entity.setBucketName(bucketName);
entity.setObjectKey(objectKey);
return entity;
}
}
阿里云根据资源路径获取资源时长代码
public int getVideoDuration(String videoUrl) {
if (StringUtils.isNotEmpty(videoUrl) && "m3u8".equals(videoUrl.substring(videoUrl.length() - 4))) {
try {
videoUrl = aliOSSUtil.getOssObjectDownAuthUrl(videoUrl);
log.info("getVideoDuration:aliOSSUtil.videoUrl ={}", videoUrl);
HttpRequest httpRequest = HttpRequest.get(videoUrl)
.timeout(30000);
log.info("getRequest httpRequest:{}", httpRequest);
HttpResponse res = httpRequest.execute();
String result = res.body();
String pattern = "\\d+[.]\\d+";
List<String> matchStrs = new ArrayList<>();
Pattern r = Pattern.compile(pattern);
Matcher m = r.matcher(result);
while (m.find()) { //此处find（）每次被调用后，会偏移到下一个匹配
matchStrs.add(m.group());//获取当前匹配的值
}
Double durationDouble = 0.0;
for (int i = 0; i < matchStrs.size(); i++) {
durationDouble += Double.parseDouble(matchStrs.get(i));
}
log.info("LiveDetailController.getVideoDuration->duration=", durationDouble.intValue());
return durationDouble.intValue();
} catch (Exception e) {
log.error("getVideoDuration 异常={}", e);
}
}
return 0;
}
这里需要注意：
HttpRequest httpRequest = HttpRequest.get(videoUrl) .timeout(30000);请求是一定不要加 .header(“Content-Type”, “application/json”) 头，不然会验证签名失败
