SpringBoot整合阿里云视频点播的过程详解
1.准备工作
首先需要在阿里云开通视频点播服务:
1.首先,进入到阿里云视频点播平台,点击开通服务,选择按使用流量计费即可
2.开通之后点击进入管理控制台即可
视频点播有什么用?
视频点播(ApsaraVideo for VoD)是集音视频采集、编辑、上传、自动化转码处理、媒体资源管理、分发加速于一体的一站式音视频点播解决方案。
2.服务端SDK的使用
官方文档链接:Java SDK
SDK
的方式将api进行了进一步的封装,不用自己创建工具类。 我们可以基于服务端SDK
编写代码来调用点播API,实现对点播产品和服务的快速操作。
2.1 导入依赖
注意:环境必须是JDK6 及以上版本
<groupId>com.aliyun</groupId>
<artifactId>aliyun-java-sdk-core</artifactId>
<version>4.5.1</version>
</dependency>
<dependency>
<groupId>com.aliyun</groupId>
<artifactId>aliyun-java-sdk-vod</artifactId>
<version>2.15.11</version>
</dependency>
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>fastjson</artifactId>
<version>1.2.62</version>
</dependency>
<dependency>
<groupId>com.aliyun</groupId>
<artifactId>aliyun-java-sdk-kms</artifactId>
<version>2.10.1</version>
</dependency>
2.2 初始化类
根据官方文档示例创建初始化类InitObject
:
/**
* @author xppll
* @date 2021/12/5 13:57
*/
public class InitObject {
//初始化:需要传入accessKeyId+accessKeySecret
public static DefaultAcsClient initVodClient(String accessKeyId, String accessKeySecret) throws ClientException {
String regionId = "cn-shanghai"; //点播服务接入区域
DefaultProfile profile = DefaultProfile.getProfile(regionId, accessKeyId, accessKeySecret);
DefaultAcsClient client = new DefaultAcsClient(profile);
return client;
}
}
accessKeyId
和accessKeySecret
的获取:
这里的初始化方法需要传入账号Access Key
信息,可以在阿里云Access Key管理创建主账号Access Key
点播服务接入区域
regionId
的获取:
点击点播控制台的存储管理,查看自己所选的区域:
在查看接入区域标识对应API/SDK的RegionId
参数:
2.3 创建读取公共常量的工具类
首先在配置文件application.properties
添加:
aliyun.vod.file.keyid=LTAI5tGqf41adadaxxAa
aliyun.vod.file.keysecret=zE4nEzmcU7GxxxxmTgWRk0tytJKD
# 最大上传单个文件大小:默认1M
spring.servlet.multipart.max-file-size=1024MB
# 最大置总上传的数据大小 :默认10M
spring.servlet.multipart.max-request-size=1024MB
在创建读取公共常量的工具类ConstantVodUtils
:
/**
* @author xppll
* @date 2021/12/2 19:11
*/
@Component
public class ConstantVodUtils implements InitializingBean {
@Value("${aliyun.vod.file.keyid}")
private String keyId;
@Value("${aliyun.vod.file.keysecret}")
private String keySecret;
//定义公共静态常量
public static String ACCESS_KEY_ID;
public static String ACCESS_KEY_SECRET;
@Override
public void afterPropertiesSet() throws Exception {
ACCESS_KEY_ID = keyId;
ACCESS_KEY_SECRET = keySecret;
}
}
2.4 获取视频播放地址
首先手动先在点播控制台上传一个视频用于测试:
步骤:
- 创建初始化对象
- 创建获取视频地址
request
和response
- 向
request
对象里面设置视频id
- 用初始化对象里面的方法
getAcsResponse
,传递request
,获取数据 - 打印信息
代码如下:
//获取视频播放地址
private static void getPlayUrl() throws ClientException {
//1.创建初始化对象
DefaultAcsClient client = InitObject.initVodClient(ConstantVodUtils.ACCESS_KEY_ID,ConstantVodUtils.ACCESS_KEY_SECRET);
//2.创建获取视频地址request和response
GetPlayInfoRequest request = new GetPlayInfoRequest();
GetPlayInfoResponse response = new GetPlayInfoResponse();
//3.向request对象里面设置视频id
request.setVideoId("ffe90bfaxxx94d0d722caad");
//4.调用初始化对象里面的方法,传递request,获取数据
response = client.getAcsResponse(request);
List<GetPlayInfoResponse.PlayInfo> playInfoList = response.getPlayInfoList();
//播放地址
for (GetPlayInfoResponse.PlayInfo playInfo : playInfoList) {
System.out.print("PlayInfo.PlayURL = " + playInfo.getPlayURL() + "\n");
}
//Base信息
System.out.print("VideoBase.Title = " + response.getVideoBase().getTitle() + "\n");
}
测试成功:
2.5 获取视频播放凭证
步骤与获取视频播放地址差不多,区别是获取request
和response
方式不同:
//获取视频播放凭证
private static void getPlayAuth() throws ClientException {
//1.创建初始化对象
DefaultAcsClient client = InitObject.initVodClient(ConstantVodUtils.ACCESS_KEY_ID,ConstantVodUtils.ACCESS_KEY_SECRET);
//2.创建获取视频凭证的request和response
GetVideoPlayAuthRequest request = new GetVideoPlayAuthRequest();
GetVideoPlayAuthResponse response = new GetVideoPlayAuthResponse();
//3.向request设置视频id
request.setVideoId("ffe90bfaaadd4xxxx0d722caad");
//4.调用初始化对象的方法得到凭证
response = client.getAcsResponse(request);
//播放凭证
System.out.println("playauth" + response.getPlayAuth());
}
测试成功:
2.6 上传视频到阿里云视频点播服务
可以参考:Java上传SDK
需要导入依赖:
<dependency>
<groupId>com.aliyun</groupId>
<artifactId>aliyun-java-sdk-core</artifactId>
<version>4.5.1</version>
</dependency>
<dependency>
<groupId>com.aliyun.oss</groupId>
<artifactId>aliyun-sdk-oss</artifactId>
<version>3.10.2</version>
</dependency>
<dependency>
<groupId>com.aliyun</groupId>
<artifactId>aliyun-java-sdk-vod</artifactId>
<version>2.15.11</version>
</dependency>
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>fastjson</artifactId>
<version>1.2.28</version>
</dependency>
<dependency>
<groupId>org.json</groupId>
<artifactId>json</artifactId>
<version>20170516</version>
</dependency>
<dependency>
<groupId>com.google.code.gson</groupId>
<artifactId>gson</artifactId>
<version>2.8.2</version>
</dependency>
代码如下:
//上传视频到阿里云视频点播服务
private static void uploadVideo() {
String accessKeyId = ConstantVodUtils.ACCESS_KEY_ID;
String accessKeySecret = ConstantVodUtils.ACCESS_KEY_SECRET;
//上传后视频的标题
String title = "xpp1";
//本地文件上传路径
String fileName = "D:/6 - What If I Want to Move Faster.mp4";
UploadVideoRequest request = new UploadVideoRequest(accessKeyId, accessKeySecret, title, fileName);
//可指定分片上传时每个分片的大小,默认为2M字节
request.setPartSize(2 * 1024 * 1024L);
//可指定分片上传时的并发线程数,默认为1
request.setTaskNum(1);
UploadVideoImpl uploader = new UploadVideoImpl();
UploadVideoResponse response = uploader.uploadVideo(request);
if (response.isSuccess()) {
System.out.print("VideoId=" + response.getVideoId() + "\n");
} else {
/* 如果设置回调URL无效,不影响视频上传,可以返回VideoId同时会返回错误码。其他情况上传失败时,VideoId为空,此时需要根据返回错误码分析具体错误原因 */
System.out.print("VideoId=" + response.getVideoId() + "\n");
System.out.print("ErrorCode=" + response.getCode() + "\n");
System.out.print("ErrorMessage=" + response.getMessage() + "\n");
}
}
测试成功:
3.springboot项目中实践
创建初始化类:
/**
* @author xppll
* @date 2021/12/5 13:57
*/
public class InitVodCilent {
//初始化:需要传入accessKeyId+accessKeySecret
public static DefaultAcsClient initVodClient(String accessKeyId, String accessKeySecret) throws ClientException {
String regionId = "cn-shanghai"; // 点播服务接入区域
DefaultProfile profile = DefaultProfile.getProfile(regionId, accessKeyId, accessKeySecret);
DefaultAcsClient client = new DefaultAcsClient(profile);
return client;
}
}
3.1 上传视频到阿里云
controller
层:
@Autowired
private VodService vodService;
//上传视频到阿里云
@PostMapping("uploadAlyiVideo")
public R uploadAlyVideo(MultipartFile file){
//返回上传视频id
String videoId=vodService.uploadVideoAly(file);
//将视频`id`返回给前端
return R.ok().data("videoId",videoId);
}
service
层:
//上传视频到阿里云
@Override
public String uploadVideoAly(MultipartFile file) {
try {
//fileName:上传文件原始名称
String fileName = file.getOriginalFilename();
//title:上传之后显示名称(例子:01.mp4=>01)
String title = fileName.substring(0, fileName.lastIndexOf("."));
//inputStream:上传文件输入流
InputStream inputStream = file.getInputStream();
//获得request
UploadStreamRequest request = new UploadStreamRequest(ConstantVodUtils.ACCESS_KEY_ID, ConstantVodUtils.ACCESS_KEY_SECRET, title, fileName, inputStream);
UploadVideoImpl uploader = new UploadVideoImpl();
//上传获得response
UploadStreamResponse response = uploader.uploadStream(request);
String videoId = null;
if (response.isSuccess()) {
//得到视频id
videoId = response.getVideoId();
} else { //如果设置回调URL无效,不影响视频上传,可以返回VideoId同时会返回错误码。其他情况上传失败时,VideoId为空,此时需要根据返回错误码分析具体错误原因
videoId = response.getVideoId();
}
return videoId;
} catch (IOException e) {
e.printStackTrace();
return null;
}
}
3.2 根据视频id删除视频
controller
层:
//根据视频id删除视频
@DeleteMapping("removeAlyVideo/{id}")
public R removeAlyVideo(@PathVariable String id){
vodService.deleteAlyVideo(id);
return R.ok();
}
service
层:
//根据视频id删除视频
@Override
public void deleteAlyVideo(String id) {
try {
//1.初始化对象
DefaultAcsClient client = InitVodCilent.initVodClient(ConstantVodUtils.ACCESS_KEY_ID, ConstantVodUtils.ACCESS_KEY_SECRET);
//2.创建删除视频的request对象
DeleteVideoRequest request=new DeleteVideoRequest();
//3.向request设置视频id
request.setVideoIds(id);
//4.调用初始化对象的方法实现删除
client.getAcsResponse(request);
} catch (Exception e) {
e.printStackTrace();
throw new GuliException(20001,"删除视频失败");
}
}
