视频点播我去年写过一篇阿里云的，这次写腾讯云。

1、腾讯云点播介绍

腾讯云点播（Video on Demand，VOD）基于腾讯多年技术积累与基础设施建设，为有音视频应用相关需求的客户提供包括音视频存储管理、音视频转码处理、音视频加速播放和音视频通信服务的一站式解决方案。

文档中心：https://cloud.tencent.com/document/product/266

1.1 开通“云点播”服务

1.2 管理控制台

1.3 上传视频

上传视频可将视频上传到云点播的存储中，以进行后续的处理和分发等。

• 单击左侧菜单栏【媒资管理 > 视频管理】，默认展示【已上传】标签页；
• 点击【上传视频】按钮；
• 单击【选择视频】，选择本地视频文件；
• 单击【开始上传】；
• 页面将自动跳转至【正在上传】标签页， 本地文件所在行【状态】栏为“上传成功”时，单击【已上传】标签页，可见完成上传的视频；

1.4 前端集成

前端集成有两种方式，使用“超级播放器预览”与“web播放器预览”，后者代码已经不更新，推荐使用前者，因此“web播放器预览”仅做了解。

1、查看“web播放器预览”；

说明：需要将视频进行转码，才能支持超级播放器播放，转码为：自适应码流

2、查看任务流设置

3、查看详情

当前任务流就是系统默认的“自适应码流”任务流

4、在【音视频管理】重新上传视频

5、查看详情

6、复制代码index.html到项目，即可播放

2、后端视频点播接口(集成Java SDK)

2.1 创建相关类

2.2 引入相关依赖

<dependency>
    <groupId>com.qcloud</groupId>
    <artifactId>vod_api</artifactId>
    <version>2.1.4</version>
    <exclusions>
        <exclusion>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-log4j12</artifactId>
        </exclusion>
    </exclusions>
</dependency>

2.3 编写Controller

**（1）上传视频集成方案：**https://cloud.tencent.com/document/product/266/10276

（2）删除视频

地址：https://console.cloud.tencent.com/api/explorer?Product=vod&Version=2018-07-17&Action=DescribeMediaInfos&SignVersion=

@Api(tags = "腾讯云点播")
@RestController
@RequestMapping("/admin/vod")
public class VodController {

    @Autowired
    private VodService vodService;

    //返回客户端上传视频的签名
    @GetMapping("sign")
    public Result sign(){
        Signature sign = new Signature();
        // 设置 App 的云 API 密钥
        sign.setSecretId(ConstantPropertiesUtil.ACCESS_KEY_ID);
        sign.setSecretKey(ConstantPropertiesUtil.ACCESS_KEY_SECRET);
        sign.setCurrentTime(System.currentTimeMillis() / 1000);
        sign.setRandom(new Random().nextInt(java.lang.Integer.MAX_VALUE));
        sign.setSignValidDuration(3600 * 24 * 2); // 签名有效期：2天
        try {
            String signature = sign.getUploadSignature();
            System.out.println("signature : " + signature);
            return Result.ok(signature);
        } catch (Exception e) {
            System.out.print("获取签名失败");
            e.printStackTrace();
            throw  new GgktException(20001,"获取签名失败");
        }
    }

    //上传视频接口
    @ApiOperation("上传视频接口")
    @PostMapping("upload")
    public Result upload(){
        String fileId=vodService.uploadVideo();
        return Result.ok(fileId);
    }

    //删除腾讯云视频
    @ApiOperation("删除腾讯云视频")
    @DeleteMapping("remove/{fileId}")
    public Result remove(@PathVariable String fileId){
        vodService.removeVideo(fileId);
        return Result.ok(null);
    }

}

2.4 编写Service

（1）VodService定义方法

public interface VodService {
    //上传视频接口
    String uploadVideo();

    //删除腾讯云视频
    void removeVideo(String fileId);
}

（2）VodServiceImpl实现方法

@Service
public class VodServiceImpl implements VodService {
    //上传视频接口
    @Override
    public String uploadVideo() {
        //指定当前腾讯云账号的id和key
        VodUploadClient client = new VodUploadClient(ConstantPropertiesUtil.ACCESS_KEY_ID,
                ConstantPropertiesUtil.ACCESS_KEY_SECRET);
        //上传请求对象
        VodUploadRequest request = new VodUploadRequest();
        //设置上传的视频文件在本地路径
        request.setMediaFilePath("I:\\temp\\faster.mp4");
        //任务流
        request.setProcedure("LongVideoPreset");
        try {
            //调用方法上传视频，指定地域
            VodUploadResponse response = client.upload("ap-guangzhou", request);
            //获取上传之后的视频id
            String fileId = response.getFileId();
            return fileId;
        } catch (Exception e) {
            // 业务方进行异常处理
            throw new GgktException(20001,"上传视频失败");
        }
    }

    //删除腾讯云视频
    @Override
    public void removeVideo(String fileId) {
        try{
            // 实例化一个认证对象，入参需要传入腾讯云账户secretId，secretKey,此处还需注意密钥对的保密
            // 密钥可前往https://console.cloud.tencent.com/cam/capi网站进行获取
            Credential cred = new Credential(ConstantPropertiesUtil.ACCESS_KEY_ID,
                    ConstantPropertiesUtil.ACCESS_KEY_SECRET);
            // 实例化一个http选项，可选的，没有特殊需求可以跳过
            HttpProfile httpProfile = new HttpProfile();
            httpProfile.setEndpoint("vod.tencentcloudapi.com");
            // 实例化一个client选项，可选的，没有特殊需求可以跳过
            ClientProfile clientProfile = new ClientProfile();
            clientProfile.setHttpProfile(httpProfile);
            // 实例化要请求产品的client对象,clientProfile是可选的
            VodClient client = new VodClient(cred, "", clientProfile);
            // 实例化一个请求对象,每个接口都会对应一个request对象
            DeleteMediaRequest req = new DeleteMediaRequest();
            req.setFileId(fileId);
            // 返回的resp是一个DeleteMediaResponse的实例，与请求对象对应
            DeleteMediaResponse resp = client.DeleteMedia(req);
            // 输出json格式的字符串回包
            System.out.println(DeleteMediaResponse.toJsonString(resp));
        } catch (TencentCloudSDKException e) {
            System.out.println(e.toString());
            throw new GgktException(20001,"删除视频失败");
        }
    }
}

这里暂时路径写死上传的，因为我在文档中并没有找到有关文件流上传方式的API。

不过腾讯云提供了客户端上传的方式，不用服务端上传也是可以的。

3、另一种上传方式：客户端上传

3.1 操作步骤一（申请上传签名）

（1）找到Java签名示例

（2）VodController编写签名接口

Signature类

import java.util.Random;
import javax.crypto.Mac;
import javax.crypto.spec.SecretKeySpec;
import sun.misc.BASE64Encoder;
public class Signature {
    private String secretId;
    private String secretKey;
    private long currentTime;
    private int random;
    private int signValidDuration;
    private static final String HMAC_ALGORITHM = "HmacSHA1"; //签名算法
    private static final String CONTENT_CHARSET = "UTF-8";
    public static byte[] byteMerger(byte[] byte1, byte[] byte2) {
        byte[] byte3 = new byte[byte1.length + byte2.length];
        System.arraycopy(byte1, 0, byte3, 0, byte1.length);
        System.arraycopy(byte2, 0, byte3, byte1.length, byte2.length);
        return byte3;
    }
    // 获取签名
    public String getUploadSignature() throws Exception {
        String strSign = "";
        String contextStr = "";
        // 生成原始参数字符串
        long endTime = (currentTime + signValidDuration);
        contextStr += "secretId=" + java.net.URLEncoder.encode(secretId, "utf8");
        contextStr += "&currentTimeStamp=" + currentTime;
        contextStr += "&expireTime=" + endTime;
        contextStr += "&random=" + random;
        //设置任务流
        contextStr+="&procedure=LongVideoPreset";
        try {
            Mac mac = Mac.getInstance(HMAC_ALGORITHM);
            SecretKeySpec secretKey = new SecretKeySpec(this.secretKey.getBytes(CONTENT_CHARSET), mac.getAlgorithm());
            mac.init(secretKey);
            byte[] hash = mac.doFinal(contextStr.getBytes(CONTENT_CHARSET));
            byte[] sigBuf = byteMerger(hash, contextStr.getBytes("utf8"));
            strSign = base64Encode(sigBuf);
            strSign = strSign.replace(" ", "").replace("\n", "").replace("\r", "");
        } catch (Exception e) {
            throw e;
        }
        return strSign;
    }
    private String base64Encode(byte[] buffer) {
        BASE64Encoder encoder = new BASE64Encoder();
        return encoder.encode(buffer);
    }
    public void setSecretId(String secretId) {
        this.secretId = secretId;
    }
    public void setSecretKey(String secretKey) {
        this.secretKey = secretKey;
    }
    public void setCurrentTime(long currentTime) {
        this.currentTime = currentTime;
    }
    public void setRandom(int random) {
        this.random = random;
    }
    public void setSignValidDuration(int signValidDuration) {
        this.signValidDuration = signValidDuration;
    }
}

VodController类

 //返回客户端上传视频的签名
    @GetMapping("sign")
    public Result sign(){
        Signature sign = new Signature();
        // 设置 App 的云 API 密钥
        sign.setSecretId(ConstantPropertiesUtil.ACCESS_KEY_ID);
        sign.setSecretKey(ConstantPropertiesUtil.ACCESS_KEY_SECRET);
        sign.setCurrentTime(System.currentTimeMillis() / 1000);
        sign.setRandom(new Random().nextInt(java.lang.Integer.MAX_VALUE));
        sign.setSignValidDuration(3600 * 24 * 2); // 签名有效期：2天
        try {
            String signature = sign.getUploadSignature();
            System.out.println("signature : " + signature);
            return Result.ok(signature);
        } catch (Exception e) {
            System.out.print("获取签名失败");
            e.printStackTrace();
            throw  new GgktException(20001,"获取签名失败");
        }
    }

3.2 操作步骤二（SDK上传）

3.3 下载Demo源码修改

3.3.1 html测试文件上传

改下代码中的这里，请求签名接口。

本来应该访问8301端口，但是我用Spring Cloud Gateway配置了网关，nacos配置了服务注册，所以这里就将请求交给网关，由网关负责转发。

运行这个html测试下：

点击上传视频按钮，选择视频

功能基本实现了。
