2. Video on demand

1. Getting started code

Upload based on OSS native SDK, refer to the document: https://help.aliyun.com/zh/vod/user-guide/upload-media-files-by-using-oss-sdks?spm=a2c4g.11186623.0.0.1f02273fj4lxNJ

VOD provides a variety of upload methods for developers. The upload SDK (server and client) encapsulates the basic logic related to upload, and only needs simple configuration to realize the upload function. It is recommended to use

Uploading based on the OSS native SDK requires the developer to implement all upload logic by himself, including obtaining the upload address and certificate from the on-demand service, Base64 decoding the upload address and certificate, and calling the OSS capability to complete the upload.
Taking the integration of the on-demand server SDK to obtain the upload address and certificate as an example, the complete upload process is shown in the figure below:
image.png
Process Details

  1. The upload application server uses the RAM user AK method (AccessKey ID and AccessKey Secret) or STS temporary AK to initialize the VOD client.
  2. The upload application server uses the on-demand server SDK to call the interface related to the upload address and certificate to obtain the upload address, upload certificate and media information.
  3. The on-demand service returns Base64-encrypted upload address (UploadAddress), upload certificate (UploadAuth), and media ID in the request result. The upload application server can parse the parameters according to the returned results as input parameters for initializing the OSS native SDK.
  4. The upload application server uses the parsed upload address (UploadAddress) and authorization information (UploadAuth) to initialize the OSS client through STS .
  5. The upload application server uses the OSS SDK to call the OSS upload related interface to upload media files to the specified storage address.
  6. The OSS service returns the upload result.

public class UploadDemo {

        return client;
    }

        return vodClient.getAcsResponse(request);
    }

    //初始OSS客户端
    public static OSSClient initOssClient(JSONObject uploadAuth, JSONObject uploadAddress) {
    
    
        String endpoint = uploadAddress.getString("Endpoint");
        String accessKeyId = uploadAuth.getString("AccessKeyId");
        String accessKeySecret = uploadAuth.getString("AccessKeySecret");
        String securityToken = uploadAuth.getString("SecurityToken");

    }

    public static void main(String[] argv) {
    
    
        //您的AccessKeyId
        String accessKeyId = "xxxxx";
        //您的AccessKeySecret
        String accessKeySecret = "xxxxx";
        //需要上传到VOD的本地视频文件的完整路径，需要包含文件扩展名

            JSONObject uploadAddress = JSONObject.parseObject(decodeBase64(createUploadVideoResponse.getUploadAddress()));

            // 使用UploadAuth和UploadAddress初始化OSS客户端
            OSSClient ossClient = initOssClient(uploadAuth, uploadAddress);
            // 上传文件，注意是同步上传会阻塞等待，耗时与文件大小和网络上行带宽有关
            uploadLocalFile(ossClient, uploadAddress, localFile);
            System.out.println("Put local file succeed, VideoId : " + videoId);

        }
    }

    private static String decodeBase64(String data) {
    
    
        return new String(Base64.decodeBase64(data));
    }
}

Note that there are three places that need to be modified

  • accessKeyId : your AccessKeyId
  • accessKeySecret: your AccessKeySecret
  • String regionId = “cn-shanghai”; This is the region, you need to go to the VOD console - storage management to find the upload address. For example, mine is: xxxxxxx[.oss-cn-shanghai.aliyuncs.com](https://vod.console.aliyun.com/?spm=5176.12818093_-1363046575.top-nav.22.3be916d0sNjf6B#/storage/outin-e978d136329c11ee80ad00163e1a3b4a.oss-cn-shanghai.aliyuncs.com/manage)East China Shanghai, then the regionId should be cn-shanghai

After the upload is successful, you can see the video ID from the console, which is required for playback

2. Play video

Go to the VOD console - media library - find the uploaded video
image.png
and click manage - you can see the basic situation of the video in the basic information, including the video ID, storage address, click on the web player code, the official provides the Html and JS script
image.png
Create a pay.html file on the computer desktop, then copy the player code into it, and then need to specify 2 things

  • vid : the id of the video
  • payauth : play credentials

image.png

3. Get payauth

Official note: Please copy the code and add the playauth value before using it. For how to obtain playauth, please refer to the document to obtain the playback certificate . We obtain the playback certificate according to the document. The document address: https://help.aliyun.com/zh/vod/developer -reference/api-vod-2017-03-21-getvideoplayauth , here you can try debugging first - get the playback certificate
image.png
, enter the debugging page, select the server address, specify the VideoId video ID, and then click to initiate the call to get the playback certificate.
image.png
Copy the playback credentials to the player code, refresh the page and try to play, and it can be seen from the network that the method of video-on-demand and side-by-side playback is adopted.

You can directly download the official code in the debug-SDK instance to obtain the playback certificate code,
image.png
and you need to import dependencies


<dependency>
    <groupId>com.aliyun</groupId>
    <artifactId>vod20170321</artifactId>
    <version>2.16.16</version>
</dependency>

Get play voucher code

//获取播放凭证
public static String getPayAuth(String videoId) throws Exception {
    
    
    // 请确保代码运行环境设置了环境变量 ALIBABA_CLOUD_ACCESS_KEY_ID 和 ALIBABA_CLOUD_ACCESS_KEY_SECRET。
    // 工程代码泄露可能会导致 AccessKey 泄露，并威胁账号下所有资源的安全性。以下代码示例使用环境变量获取 AccessKey 的方式进行调用，仅供参考，建议使用更安全的 STS 方式，更多鉴权访问方式请参见：https://help.aliyun.com/document_detail/378657.html
    com.aliyun.vod20170321.Client client =
            createClient("你的accessKeyId", "你的accessKeySecrt");

    com.aliyun.vod20170321.models.GetVideoPlayAuthRequest getVideoPlayAuthRequest =
            new com.aliyun.vod20170321.models.GetVideoPlayAuthRequest().setVideoId(videoId);

    com.aliyun.teautil.models.RuntimeOptions runtime = new com.aliyun.teautil.models.RuntimeOptions();
    // 复制代码运行请自行打印 API 的返回值
    GetVideoPlayAuthResponse videoPlayAuthWithOptions = client.getVideoPlayAuthWithOptions(getVideoPlayAuthRequest, runtime);
    String playAuth = videoPlayAuthWithOptions.getBody().getPlayAuth();
    return playAuth;
}

I believe you have finished running the process according to the document, and then you can connect the code to your project
