• 阿里云VOD(二)


    一、准备工作

    1、设置不转码

    测试之前设置默认“不转码”,以节省开发成本

    2、找到子账户的AccessKey ID

    3、给子账户添加授权

    AliyunVODFullAccess

    4、阅读文档

    服务端API:

    API调用示例参考:https://help.aliyun.com/document_detail/44435.html?spm=a2c4g.11186623.6.708.2c643d44SY21Hb
    服务端SDK:

    SDK将API进行了进一步的封装,使用起来更简单方便

    二、创建和初始化项目

    1、创建maven项目

    Group:com.atguigu
    Artifact:aliyun_vod

    2、添加Maven依赖

    <dependencies>
        <dependency>
            <groupId>com.aliyun</groupId>
            <artifactId>aliyun-java-sdk-core</artifactId>
            <version>4.3.3</version>
        </dependency>
        <dependency>
            <groupId>com.aliyun</groupId>
            <artifactId>aliyun-java-sdk-vod</artifactId>
            <version>2.15.2</version>
        </dependency>
        <dependency>
            <groupId>com.google.code.gson</groupId>
            <artifactId>gson</artifactId>
            <version>2.8.2</version>
        </dependency>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.12</version>
        </dependency>
    </dependencies>
    

    3、创建测试类并初始化

    参考文档:https://help.aliyun.com/document_detail/61062.html

    package com.atguigu.aliyunvod;
    
    public class VodSdkTest {
        public static DefaultAcsClient initVodClient(String accessKeyId, String accessKeySecret) {
            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;
    	}
    }
    

    三、创建测试用例

    1、获取视频播放地址

    参考文档:https://help.aliyun.com/document_detail/61064.html

    /*获取播放地址函数*/
    public static GetPlayInfoResponse getPlayInfo(DefaultAcsClient client) throws Exception {
        GetPlayInfoRequest request = new GetPlayInfoRequest();
        request.setVideoId("视频ID");
        //request.setResultType("Multiple"); //如果视频id是加密视频的id,则需要设置此参数。但只能获取文件无法解密播放
        return client.getAcsResponse(request);
    }
    
    @Test
    public void testGetPlayInfo(){
        DefaultAcsClient client = initVodClient("<您的AccessKeyId>", "<您的AccessKeySecret>");
        GetPlayInfoResponse response = new GetPlayInfoResponse();
    
        try {
            response = getPlayInfo(client);
            List<GetPlayInfoResponse.PlayInfo> playInfoList = response.getPlayInfoList();
            //播放地址
            for (GetPlayInfoResponse.PlayInfo playInfo : playInfoList) {
                System.out.print("PlayInfo.PlayURL = " + playInfo.getPlayURL() + "
    ");
            }
            //Base信息
            System.out.print("VideoBase.Title = " + response.getVideoBase().getTitle() + "
    ");
        } catch (Exception e) {
            System.out.print("ErrorMessage = " + e.getLocalizedMessage());
        }
        System.out.print("RequestId = " + response.getRequestId() + "
    ");
    }
    

    2、获取视频播放凭证

    参考文档:https://help.aliyun.com/document_detail/61064.html#h2--div-id-getvideoplayauth-div-2

    加密视频必须使用此方式播放

    /*获取播放凭证函数*/
    public static GetVideoPlayAuthResponse getVideoPlayAuth(DefaultAcsClient client) throws Exception {
        GetVideoPlayAuthRequest request = new GetVideoPlayAuthRequest();
        request.setVideoId("视频ID");
        return client.getAcsResponse(request);
    }
    
    /*以下为调用示例*/
    @Test
    public void testGetVideoPlayAuth() {
    
        DefaultAcsClient client = initVodClient("<您的AccessKeyId>", "<您的AccessKeySecret>");
        GetVideoPlayAuthResponse response = new GetVideoPlayAuthResponse();
        try {
            response = getVideoPlayAuth(client);
            //播放凭证
            System.out.print("PlayAuth = " + response.getPlayAuth() + "
    ");
            //VideoMeta信息
            System.out.print("VideoMeta.Title = " + response.getVideoMeta().getTitle() + "
    ");
        } catch (Exception e) {
            System.out.print("ErrorMessage = " + e.getLocalizedMessage());
        }
        System.out.print("RequestId = " + response.getRequestId() + "
    ");
    }
