项目需求用到阿里云点播系统，用到一些高级功能，采用凭证播放。提供接口给前端，前端获取凭证就可直接使用。

public GetVideoPlayAuthResponse getVideoPlayAuth(String mediaId) {
        try {
            StaticCredentialProvider provider = StaticCredentialProvider.create(Credential.builder()
                    .accessKeyId(accessKeyId)
                    .accessKeySecret(accessKeySecret)
                    .build());
            AsyncClient client = AsyncClient.builder()
                    .region("cn-beijing")
                    .credentialsProvider(provider)
                    .overrideConfiguration(
                            ClientOverrideConfiguration.create()
                                    .setEndpointOverride("vod.cn-beijing.aliyuncs.com")
                                    .setConnectTimeout(Duration.ofSeconds(10))//到期秒
                    )
                    .build();
            GetVideoPlayAuthRequest getVideoPlayAuthRequest = GetVideoPlayAuthRequest.builder()
                    .videoId(mediaId)
                    .build();
            CompletableFuture<GetVideoPlayAuthResponse> response = client.getVideoPlayAuth(getVideoPlayAuthRequest);
            GetVideoPlayAuthResponse resp = response.get();
            return resp;
        }catch (Exception e){
            return null;
        }
    }

然后在出个restapi接口给前端就可。
