2.1、引入依赖

<dependencies>
     <dependency>
         <groupId>com.aliyun</groupId>
         <artifactId>aliyun-java-sdk-core</artifactId>
     </dependency>

         <artifactId>gson</artifactId>
     </dependency>

     <dependency>
         <groupId>joda-time</groupId>
         <artifactId>joda-time</artifactId>
     </dependency>
 </dependencies>

2.2、初始化类

public class InitObject {

    public static DefaultAcsClient initVodClient(String accessKeyId, String accessKeySecret) throws ClientException {
        String regionId = "cn-guangzhou";  // 点播服务接入区域
        DefaultProfile profile = DefaultProfile.getProfile(regionId, accessKeyId, accessKeySecret);
        DefaultAcsClient client = new DefaultAcsClient(profile);
        return client;
    }
}

2.3、测试类

public class TestVod {

    public static void main(String[] args) {
        String accessKeyId = "xxxx";
        String accessKeySecret = "xxxxx";

        String title = "6 - What If I Want to Move Faster - upload by sdk";   //上传之后文件名称
        String fileName = "E:\\aaaaa\\6 - What If I Want to Move Faster.mp4";  //本地文件路径和名称
        //上传视频的方法
        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，(注：该配置会占用服务器CPU资源，需根据服务器情况指定）*/
        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");
        }
    }

    //1 根据视频iD获取视频播放凭证
    public static void getPlayAuth() throws Exception{

        DefaultAcsClient client = InitObject.initVodClient("xxxx", "xxxx");

        GetVideoPlayAuthRequest request = new GetVideoPlayAuthRequest();
        GetVideoPlayAuthResponse response = new GetVideoPlayAuthResponse();

        request.setVideoId("990b13273e004b088da9a456ba425e28");

        response = client.getAcsResponse(request);
        System.out.println("playAuth:"+response.getPlayAuth());
    }
    //1 根据视频iD获取视频播放地址
    public static void getPlayUrl() throws Exception{
        //创建初始化对象
        DefaultAcsClient client = InitObject.initVodClient("xxxx", "xxxx");

        //创建获取视频地址request和response
        GetPlayInfoRequest request = new GetPlayInfoRequest();
        GetPlayInfoResponse response = new GetPlayInfoResponse();

        //向request对象里面设置视频id
        request.setVideoId("990b13273e004b088da9a456ba425e28");

        //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");
    }
}

2.4、运行

2.5、查看云服务器

使用springboot进行上传

3.1、引入依赖（同上）

3.2、配置application文件

# 服务端口
server.port=8003
# 服务名
spring.application.name=service-vod

# 环境设置：dev、test、prod
spring.profiles.active=dev

#阿里云 vod
#不同的服务器，地址不同
aliyun.vod.file.keyid=xxxx
aliyun.vod.file.keysecret=xxxx

# 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

3.3、获取配置中的值的Bean

@Component
public class ConstantVodUtils implements InitializingBean {

    @Value("${aliyun.vod.file.keyid}")
    private String keyid;

    @Value("${aliyun.vod.file.keysecret}")
    private String keysecret;

    public static String ACCESS_KEY_SECRET;
    public static String ACCESS_KEY_ID;

    @Override
    public void afterPropertiesSet() throws Exception {
        ACCESS_KEY_ID = keyid;
        ACCESS_KEY_SECRET = keysecret;
    }
}

3.4、controller代码

@RestController
@RequestMapping("/eduvod/video")
@CrossOrigin
public class VodController {

    @Autowired
    private VodService vodService;

    //上传视频到阿里云
    @PostMapping("uploadAlyiVideo")
    public R uploadAlyiVideo(MultipartFile file) {
        //返回上传视频id
        String videoId = vodService.uploadVideoAly(file);
        return R.ok().data("videoId",videoId);
    }
}

3.5、service代码

@Service
public class VodServiceImpl implements VodService {

    @Override
    public String uploadVideoAly(MultipartFile file) {

        try {
            //accessKeyId, accessKeySecret
            //fileName：上传文件原始名称
            // 01.03.09.mp4
            String fileName = file.getOriginalFilename();
            //title：上传之后显示名称
            String title = fileName.substring(0, fileName.lastIndexOf("."));
            //inputStream：上传文件输入流
            InputStream inputStream = file.getInputStream();
            UploadStreamRequest request = new UploadStreamRequest(ConstantVodUtils.ACCESS_KEY_ID,ConstantVodUtils.ACCESS_KEY_SECRET, title, fileName, inputStream);

            UploadVideoImpl uploader = new UploadVideoImpl();
            UploadStreamResponse response = uploader.uploadStream(request);

            String videoId = null;
            if (response.isSuccess()) {
                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(Exception e) {
            e.printStackTrace();
            return null;
        }

    }
}

3.6、swagger测试

3.7、服务器查看

整合前端进行上传

4.1 有nginx进行反向代理的设置

4.1.1、设置请求转发地址

location ~ /vod/ {           
    proxy_pass http://localhost:8003;
}

4.1.2、设置上传文件的大小限制

配置nginx上传文件大小，否则上传时会有 413 (Request Entity Too Large) 异常；
打开nginx主配置文件nginx.conf，找到http{}，添加

client_max_body_size 1024m;

4.1.3、重启服务

nginx -s reload

或者 先关闭再启动

#关闭服务
nginx.exe -s stop
#启用
nginx.exe

4.2、前端实现-数据定义

fileList: [],//上传文件列表
BASE_API: process.env.BASE_API // 接口API地址

4.3、整合上传组件

<el-form-item label="上传视频">
     <el-upload
         :on-success="handleVodUploadSuccess"
         :on-remove="handleVodRemove"
         :before-remove="beforeVodRemove"
         :on-exceed="handleUploadExceed"
         :file-list="fileList"
         :action="BASE_API+'/eduvod/video/uploadAlyiVideo'"
         :limit="1"
         class="upload-demo">
     <el-button size="small" type="primary">上传视频</el-button>
     <el-tooltip placement="right-end">
         <div slot="content">最大支持1G，<br>
             支持3GP、ASF、AVI、DAT、DV、FLV、F4V、<br>
             GIF、M2T、M4V、MJ2、MJPEG、MKV、MOV、MP4、<br>
             MPE、MPG、MPEG、MTS、OGG、QT、RM、RMVB、<br>
             SWF、TS、VOB、WMV、WEBM 等视频格式上传</div>
         <i class="el-icon-question"/>
     </el-tooltip>
     </el-upload>
 </el-form-item>

4.4、方法回调

 //上传视频成功调用的方法
 handleVodUploadSuccess(response, file, fileList) {
     //上传视频id赋值
     this.video.videoSourceId = response.data.videoId
     //上传视频名称赋值
     this.video.videoOriginalName = file.name
 },
 handleUploadExceed() {
     this.$message.warning('想要重新上传视频，请先删除已上传的视频')
 },

4.5、页面上传文件

4.6、查看服务器

点击x删除上传

5.1、初始化类

public class InitVodCilent {

    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;
    }
}

5.2、删除接口

//根据视频id删除阿里云视频
 @DeleteMapping("removeAlyVideo/{id}")
 public R removeAlyVideo(@PathVariable String id) {
     try {
         //初始化对象
         DefaultAcsClient client = InitVodCilent.initVodClient(ConstantVodUtils.ACCESS_KEY_ID, ConstantVodUtils.ACCESS_KEY_SECRET);
         //创建删除视频request对象
         DeleteVideoRequest request = new DeleteVideoRequest();
         //向request设置视频id
         request.setVideoIds(id);
         //调用初始化对象的方法实现删除
         client.getAcsResponse(request);
         return R.ok();
     }catch(Exception e) {
         e.printStackTrace();
         throw new GuliException(20001,"删除视频失败");
     }
 }

5.3、前端方法

5.4、点击x的事件，对应的方法

 //点击确定调用的方法
 handleVodRemove() {
 //调用接口的删除视频的方法
 video.deleteAliyunvod(this.video.videoSourceId)
     .then(response => {
         //提示信息
         this.$message({
             type: 'success',
             message: '删除视频成功!'
         });
         //把文件列表清空
         this.fileList = []
         //把video视频id和视频名称值清空
         //上传视频id赋值
         this.video.videoSourceId = ''
         //上传视频名称赋值
         this.video.videoOriginalName = ''
     })
},
//点击×调用这个方法
beforeVodRemove(file,fileList) {
 return this.$confirm(`确定移除 ${ file.name }？`);
},

5.5、页面效果

5.6、服务器查看，已经删除

结束！！！！
