阿里云视频点播服务得到视频播放路径和播放凭证_java 后端如何获取阿里云音视频播放凭证

1.在模块中引入相关依赖 （父模块中管理依赖设置依赖版本）

子模块中的pom.xml

2.开通阿里云视频点播服务 按流量计费

3. 创建初始化类（阿里云提供的java SDK文档中）

package com.kaki.testvod;

import com.aliyun.oss.ClientException;
import com.aliyuncs.DefaultAcsClient;
import com.aliyuncs.profile.DefaultProfile;


public class InitObject {

    public static DefaultAcsClient initVodClient(String accessKeyId, String accessKeySecret) throws ClientException {
        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;
    }
}
