CRMEB知识付费二次开发 加密阿里云视频MP4点播链接为m3u8格式 hls blob协议

只有添加分发加速的域名才能使用HLS加密，同时也要做HTTPS证书添加，不然也会报错。
1、这是电脑端视频播放页面效果

2、这个手机端H5视频播放页面效果

3、在网站后台上传你的视频内容

4、上传完之后可以进行预览
5、在阿里云控制台设置就好自己的转码模板
将不转码设为默认的原因是自动触发转码不支持HLS标准加密，所以需要先上传不转码，然后根据回调再去调用转码接口，实现手动转码

6、设置上传完成回调 - 用于手动转码

7、创建回调接口
可以用frp搭一个，然后就是正常的restful接口
回调是POST请求，然后请求体我是用 @RequestBody String body接收的，不知道为什么，用对象接收就是不行
请求转码需要用到KMS加密，因此需要准备文档中准备工作的第三步搭建密钥管理服务生成AES_128密钥

// 示例代码
技术开发QQ 735660248
// getClient()是我封装的获取client对象的方法
IAcsClient client = getClient();
CommonRequest request = new CommonRequest();
request.setSysMethod(MethodType.POST);
request.setSysVersion("2016-01-20");
// 一定要和自己的服务地区相匹配
request.setSysDomain("kms.cn-shenzhen.aliyuncs.com");
request.setSysAction("GenerateDataKey");
// kms服务仅支持HTTPS
request.setSysProtocol(ProtocolType.HTTPS);
// 提交工单后，工作人员会帮你生成，前往KMS控制台就能看到
request.putQueryParameter("KeyId", "KMS控制台中的id");
request.putQueryParameter("KeySpec", "AES_128");
CommonResponse response = client.getCommonResponse(request);
// 封装了一个对象来存储aes_128
aes128 = JSON.parseObject(response.getData(), AliyunGenAes128Vo.class);
log.info("生成AES_128 {}", aes128);

8、请求转码

/**
 * 提交转码请求  技术开发QQ 735660248
 */
public static void submitTranscodeJobs(String videoId) throws ClientException {
    
    
    IAcsClient client = getClient();
    CommonRequest request = new CommonRequest();
    request.setSysMethod(MethodType.POST);
    request.setSysDomain("vod.cn-shenzhen.aliyuncs.com");
    request.setSysVersion("2017-03-21");
    request.setSysAction("SubmitTranscodeJobs");
    // 转码模板
    request.putQueryParameter("TemplateGroupId", "转码模板id");
    request.putQueryParameter("VideoId", videoId);
    request.putQueryParameter("EncryptConfig", genEncryptConfigStr());
    CommonResponse response = client.getCommonResponse(request);
    log.info("发送转码请求成功 {}", response.getData());
}

/**
 * 获取加密配置字符串
 */
private static String genEncryptConfigStr() throws ClientException {
    
    
	// 上面生成的aes128对象
    AliyunGenAes128Vo aes128 = genAes128();
    AliyunEncryptConfig encryptConfig = new AliyunEncryptConfig();
    encryptConfig.setCipherText(aes128.getCiphertextBlob());
    encryptConfig.setKeyServiceType("KMS");
    // 自己的服务，等会创建接口
    encryptConfig.setDecryptKeyUri("http://test.abc.com/play?Ciphertext=" + aes128.getCiphertextBlob());
    String jsonString = JSON.toJSONString(encryptConfig);
    log.info("加密信息 {}", jsonString);
    return jsonString;
}

这样文件上传完成后就会转码生成加密文件了

9、开通加密播放

10、获取视频信息或凭证

/**
     * 获取视频信息 - 播放地址等  技术开发QQ 735660248
     * @param videoId 阿里云视频id
     */
    public static AliyunPlayInfo getPlayInfo(String videoId) throws Exception {
    
    
        IAcsClient client = getClient();
        CommonRequest request = new CommonRequest();
        request.setSysMethod(MethodType.POST);
        request.setSysDomain("vod.cn-shenzhen.aliyuncs.com");
        request.setSysVersion("2017-03-21");
        request.setSysAction("GetPlayInfo");
        request.putQueryParameter("VideoId", videoId);
        CommonResponse response = client.getCommonResponse(request);
        AliyunPlayInfo playInfo = JSON.parseObject(response.getData(), AliyunPlayInfo.class);
        JSONObject jsonObject = JSONObject.parseObject(playInfo.getInfoStr());
        String listJson = jsonObject.getString("PlayInfo");
        playInfo.setPlayInfoList(JSON.parseArray(listJson, AliyunPlayInfo.PlayInfo.class));
        return playInfo;
    }

11、获取上传凭证 - 用于上传视频

// AliStsResVo 自己封装的对象
public ReturnResult<AliUploadAuthResVo> uploadAuth(@RequestBody AliStsResVo vo) {
    
    
        // 点播服务所在的Region，接入服务中心为上海，则填cn-shanghai
        String regionId = "cn-shenzhen";
        IClientProfile profile = DefaultProfile.getProfile(regionId, vo.getKeyId(), vo.getKeySecret(), vo.getToken());
        DefaultAcsClient client = new DefaultAcsClient(profile);

        CommonRequest request = new CommonRequest();
        request.setSysMethod(MethodType.POST);
        request.setSysDomain("vod.cn-shenzhen.aliyuncs.com");
        request.setSysVersion("2017-03-21");
        request.setSysAction("CreateUploadVideo");
        request.putQueryParameter("Title", vo.getFileName());
        request.putQueryParameter("FileName", vo.getFilePath());
        try {
    
    
            CommonResponse response = client.getCommonResponse(request);
            AliUploadAuthResVo uploadAuthResVo = JSON.parseObject(response.getData(), AliUploadAuthResVo.class);
            return ReturnResult.success(uploadAuthResVo);
        } catch (ClientException e) {
    
    
            e.printStackTrace();
            return ReturnResult.error();
        }
    }

12、上传凭证有效期为3000秒， 刷新凭证

public ReturnResult<AliUploadAuthResVo> refreshUploadAuth(@RequestBody AliStsResVo vo) {
    
    
        DefaultProfile profile = DefaultProfile.getProfile("cn-shenzhen", vo.getKeyId(), vo.getKeySecret(), vo.getToken());
        IAcsClient client = new DefaultAcsClient(profile);
        CommonRequest request = new CommonRequest();
        request.setSysMethod(MethodType.POST);
        request.setSysDomain("vod.cn-shenzhen.aliyuncs.com");
        request.setSysVersion("2017-03-21");
        request.setSysAction("RefreshUploadVideo");
        request.putQueryParameter("VideoId", vo.getVideoId());

        try {
    
    
            CommonResponse response = client.getCommonResponse(request);
            AliUploadAuthResVo uploadAuthResVo = JSON.parseObject(response.getData(), AliUploadAuthResVo.class);
            return ReturnResult.success(uploadAuthResVo);
        } catch (Exception e) {
    
    
            e.printStackTrace();
            return ReturnResult.error();
        }
    }

13、CRMEB阿里云视频加密
设置上传完成回调 - 用于手动转码

15、获取视频凭证

/**
     *
     * @param videoId 阿里云视频id
     * @param timeout 凭证有效期 100-3000 秒
     */
    public static AliyunPlayAuth getPlayAuth(String videoId, String timeout) throws Exception {
    
    
        IAcsClient client = getClient();
        CommonRequest request = new CommonRequest();
        request.setSysMethod(MethodType.POST);
        request.setSysDomain("vod.cn-shenzhen.aliyuncs.com");
        request.setSysVersion("2017-03-21");
        request.setSysAction("GetVideoPlayAuth");
        request.putQueryParameter("VideoId", videoId);
        request.putQueryParameter("AuthInfoTimeout", timeout);
        CommonResponse response = client.getCommonResponse(request);
        return JSON.parseObject(response.getData(), AliyunPlayAuth.class);
    }

16、用到的两个对象

@Data
@ApiModel("视频详细信息")
public class AliyunPlayInfo {
    
    
    @JSONField(name = "VideoBase")
    private VideoBase videoBase;
    @JSONField(name = "PlayInfoList")
    private String infoStr;
    private List<PlayInfo> playInfoList;


    @Data
    public static class VideoBase {
    
    
        @ApiModelProperty("阿里云视频id")
        @JSONField(name = "VideoId")
        private String videoId;
        @ApiModelProperty("封面地址")
        @JSONField(name = "CoverURL")
        private String coverURL;
        @ApiModelProperty("阿里云视频名")
        @JSONField(name = "Title")
        private String title;
        @ApiModelProperty("视频时长 秒")
        @JSONField(name = "Duration")
        private String duration;
    }
    @Data
    public static class PlayInfo {
    
    
        @ApiModelProperty("视频字节")
        @JSONField(name = "Size")
        private Long size;
        @ApiModelProperty("播放地址")
        @JSONField(name = "PlayURL")
        private String playURL;
        @ApiModelProperty("帧率")
        @JSONField(name = "Fps")
        private String fps;
        @ApiModelProperty("高")
        @JSONField(name = "Height")
        private String height;
        @ApiModelProperty("宽")
        @JSONField(name = "Width")
        private String width;
        @ApiModelProperty("FD：流畅。\n" +
                "LD：标清。\n" +
                "SD：高清。\n" +
                "HD：超清\n" +
                "OD：原画。\n" +
                "2K：2K。\n" +
                "4K：4K。\n" +
                "SQ：普通音质。\n" +
                "HQ：高音质。\n" +
                "AUTO：自适应码率。")
        @JSONField(name = "Definition")
        private String definition;
    }
}

@Data
@ApiModel("视频播放凭证")
public class AliyunPlayAuth {
    
    
    @JSONField(name = "PlayAuth")
    @ApiModelProperty("凭证")
    private String playAuth;
    @JSONField(name = "VideoMeta")
    @ApiModelProperty("视频信息")
    private AliyunPlayInfo.VideoBase videoMeta;
}

17、此时获取的视频是加密的
可以测试一下
前往阿里在线诊断地址
选择视频播放
将上面获取的视频的地址放到Source中，点击播放。F12查看网络请求， 发现它一直往第四步请求转码中genEncryptConfigStr()方法中设置的setDecryptKeyUri发送请求，所以需要搭建一个解密的接口

解密

@GetMapping("play")
    public void play(@RequestParam String Ciphertext, HttpServletResponse response) throws IOException {
    
    
        //从KMS中解密出来，并Base64 decode
        byte[] key = decrypt(Ciphertext);
        //设置header
        response.setHeader("Access-Control-Allow-Origin", "*");
        response.setStatus(200);
        response.setContentLength(key.length);
        //返回base64decode之后的密钥
        response.getOutputStream().write(key);
    }
    private byte[] decrypt(String ciphertext) {
    
    
        DecryptRequest request = new DecryptRequest();
        request.setCiphertextBlob(ciphertext);
        request.setSysProtocol(ProtocolType.HTTPS);
        try {
    
    
            DecryptResponse response = AliyunVideoUtils.getClient().getAcsResponse(request);
            String plaintext = response.getPlaintext();
            //注意：需要base64 decode
            return Base64.decodeBase64(plaintext);
        } catch (ClientException e) {
    
    
            e.printStackTrace();
            return null;
        }
    }

18、这样再次点击播放就能成功播放了
不过这里面我并没有进行安全认证，所以后续需要安全认证需要自己手动添加
设置URL鉴权

19、开启URL鉴权后，在生成视频地址后面就会增加一个auth_key
但是此时在点击视频播放就会出现跨域问题，因此需要在HTTP头这里设置
