谷粒学院-14-视频点播

CoderWangEx 2021-08-16 09:30 原文

API和SDK调用方式：

API：阿里云提供固定的地址，只需要调用这个固定的地址，向地址传递参数，实现功能（需要用到httpClient技术）

SDK：sdk是在服务层调用对应的源码，调用阿里云提供的类和接口里面的方法就可以实现视频功能（实际上就是对api进行了封装

获取播放地址（新）：

因为上传视频可以进行加密，加密之后，使用加密地址是不能进行视频播放的，所以在数据库中不存储地址而是存储 视频id，每次上传视频之后，都可以获取到视频id，这个视频id可以获取到视频的播放地址和播放凭证

初始化client对象

public static com.aliyun.vod20170321.Client createClient(String accessKeyId, String accessKeySecret) throws Exception {
    Config config = new Config()
            // 您的AccessKey ID
            .setAccessKeyId(accessKeyId)
            // 您的AccessKey Secret
            .setAccessKeySecret(accessKeySecret);
    // 访问的域名
    config.endpoint = "vod.cn-shenzhen.aliyuncs.com";
    return new com.aliyun.vod20170321.Client(config);
}

获取视频url

public static void main(String[] args) throws Exception {
    //1、先得到client
    com.aliyun.vod20170321.Client client = testVod2.createClient("LTAI4G499pxUfMrAJ2TXuCJz", "et6OsY7VZMfZ84oKbJIjqP3TT7KTCO");
    //2、根据需要创建对应的request
    GetPlayInfoRequest getPlayInfoRequest = new GetPlayInfoRequest()
            .setVideoId("33fab662eec64e29826c36ef18eee017");
    //3、根据创建的request，在client上使用不同的方法去调用这个request
    GetPlayInfoResponse playInfo = client.getPlayInfo(getPlayInfoRequest);
    //4、然后我们得到的就是一个类似与json的数据
    System.out.println(playInfo.body.playInfoList.playInfo.get(0).playURL);
}

获取上传凭证

跟上图一致：就是创建的request不是GetPlayInfoRequest了，而是GetVideoPlayAuthRequest

public static void main(String[] args) throws Exception {
                com.aliyun.vod20170321.Client client = testVod2.createClient("LTAI4G499pxUfMrAJ2TXuCJz", "et6OsY7VZMfZ84oKbJIjqP3TT7KTCO");
System.out.println("-------------------------------");
            GetVideoPlayAuthRequest request = new GetVideoPlayAuthRequest().setVideoId("33fab662eec64e29826c36ef18eee017").setAuthInfoTimeout(3000L);
            GetVideoPlayAuthResponse videoPlayAuth = client.getVideoPlayAuth(request);
            System.out.println(videoPlayAuth.body.playAuth);
}

videoPlayAuth的数据

手动上传maven仓库：

找到案例，打开lib里面的jar包

现在需要把aliyun-java-vod-upload-1.4.11.jar传到maven仓库中

在这个文件夹位置使用命令行

mvn install:install-file
-DgroupId=com.aliyun
-DartifactId=aliyun-sdk-vod-upload
-Dversion=1.4.11
-Dpackaging=jar
-Dfile=aliyun-java-vod-upload-1.4.11.jar
--------------------------------------------------------
mvn install:install-file -DgroupId=com.aliyun -DartifactId=aliyun-sdk-vod-upload -Dversion=1.4.11 -Dpackaging=jar -Dfile=aliyun-java-vod-upload-1.4.11.jar

删除播放视频：
