阿里AIGC视频生成 阿里全部视频

1. 开通服务

点击管理控制台 选择按照流量计费 无脑下一步即可

2. 点击管理控制台

3. 修改视频上传的配置

4. 存储管理

5. 转码模板组下面加一个

进入开发文档中

6. 查看需要的内容’

API：阿里云提供固定的地址，只需要调用这个固定的地址，向地址传递参数，实现功能（httpClient调用API技术）

SDK：对API进行了封装，使用起来更加方便

7. 准备

引入jar包

        <dependency>
            <groupId>com.aliyun</groupId>

        </dependency>
    </dependencies>

这里有aliyun-sdk-vod-upload 这个jar包打不上去 因为没有进行公开
需要自己进行手动打入 可以参考下面的教程

8. 初始化操作

//初始化操作
    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;
    }

注意：cn-shanghai不可修改

9. 获取播放的地址和文件的名字

//获取播放的地址 名字
    @Test
    public void getPalyUrl()throws Exception{
        //1. 根据视频ID获取视频播放地址
        //创建初始化对象
        DefaultAcsClient client = InitObject.initVodClient("LTAI5tJzcCqspcFTRYdzatuH", "S3ZDCVB8CoinJV9KHj005c4N4VceVg");

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

        //向request对象里设置视频id
        request.setVideoId("aed1a27150a94978ae51b15465288731");
        //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");

    }

10. 得到播放的凭证

public static  void getPlayAuth() throws ClientException, com.aliyuncs.exceptions.ClientException {
        //根据视频id获取视频播放凭证
        //创建初始化对象
        DefaultAcsClient client = InitObject.initVodClient("LTAI5tJzcCqspcFTRYdzatuH", "S3ZDCVB8CoinJV9KHj005c4N4VceVg");
        //获取视频凭证的request和response对象
        GetVideoPlayAuthRequest request = new GetVideoPlayAuthRequest();
        GetVideoPlayAuthResponse response = new GetVideoPlayAuthResponse();
        //设置视频的id值
        request.setVideoId("aed1a27150a94978ae51b15465288731");
        //调用初始化对象的方法得到凭证
        response = client.getAcsResponse(request);
        System.out.println("palyauth:::"+response.getPlayAuth());

    }

11. 上传视频的方法

public static void main(String[] args)  {

        //上传视频的方法
        String accessKeyId = "LTAI5tJzcCqspzatuH";//修改为自己的
        String accessKeySecret = "S3ZDCVB8Coi5c4N4VceVg";//修改为自己的

        String title = "6 - What If I Want to Move Faster - upload by sdk";   //上传之后文件名称
        String fileName = "F:/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");
        }

    }

12. 播放视频

• 工具类

@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_ID;
    public static String ACCESS_KEY_SECRET;

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

    }
}

12.1 编写获取视频凭证的接口

//根据视频id获取视频凭证
    @GetMapping("getPlayAuth/{id}")
    public R getPlayAuth(String id){
        try {
            //创建初始化对象
            DefaultAcsClient client = InitVodClient.initVodClient(ConstantVodUtils.ACCESS_KEY_ID, ConstantVodUtils.ACCESS_KEY_SECRET);
            //创建获取凭证的request和respond对象
            GetVideoPlayAuthRequest request = new GetVideoPlayAuthRequest();
            GetVideoPlayAuthResponse response = new GetVideoPlayAuthResponse();

            //向request中设置视频的id
            request.setVideoId(id);
            GetVideoPlayAuthResponse authResponse = client.getAcsResponse(request);
            String playAuth = authResponse.getPlayAuth();
            return R.ok().data("playAuth",playAuth);
        }catch (Exception e){
              new GuliException(20001,"获取视频凭证异常");
              return R.ok();
        }

    }

12.2 前端

点击查看视频按钮

<ol class="lh-menu-ol" style="display: block;">
                              <li class="lh-menu-second ml30" v-for="video in chapter.children" :key="video.id">
                                <a :href="'/player/'+video.videoSourceId" target="_blank">
                                  <span class="fr">
                                    <i class="free-icon vam mr10">免费试听</i>
                                  </span>
                                  <em class="lh-menu-i-2 icon16 mr5"> </em>{{video.title}}
                                </a>
                              </li>
                              
                            </ol>

paly文件夹下面的_vid.vue
播放页面

          })
      }
