视频点播

1、初始化服务

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;
    }

2、获取视频ID

 public static void getPlayUrl()throws ClientException {
        //获取视频id
        DefaultAcsClient client = InitObject.initVodClient("自己的ACCESS_KEY_ID", "自己的ACCESS_KEY__SECRET");
        GetPlayInfoRequest request=new GetPlayInfoRequest();
        GetPlayInfoResponse response = new GetPlayInfoResponse();
        request.setVideoId("视频id");
        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、获取私密播放视频凭证

 //获取视频播放凭证
    public static void getPlayAuth() throws Exception {
        DefaultAcsClient client = InitObject.initVodClient("自己的ACCESS_KEY_ID", "自己的ACCESS_KEY__SECRET");
        GetVideoPlayAuthResponse response = new GetVideoPlayAuthResponse();

        response = getVideoPlayAuth(client);
        //播放凭证
        System.out.print("PlayAuth = " + response.getPlayAuth() + "\n");
        //VideoMeta信息
        System.out.print("VideoMeta.Title = " + response.getVideoMeta().getTitle() + "\n");

        System.out.print("RequestId = " + response.getRequestId() + "\n");
    }
    public static GetVideoPlayAuthResponse getVideoPlayAuth(DefaultAcsClient client) throws Exception {
        GetVideoPlayAuthRequest request = new GetVideoPlayAuthRequest();
        request.setVideoId("视频id");
        return client.getAcsResponse(request);
    }
