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() + "\n");
}
//Base信息
System.out.print("VideoBase.Title = " + response.getVideoBase().getTitle() + "\n");
} catch (Exception e) {
System.out.print("ErrorMessage = " + e.getLocalizedMessage());
}
System.out.print("RequestId = " + response.getRequestId() + "\n");
}
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() + "\n");
//VideoMeta信息
System.out.print("VideoMeta.Title = " + response.getVideoMeta().getTitle() + "\n");
} catch (Exception e) {
System.out.print("ErrorMessage = " + e.getLocalizedMessage());
}
System.out.print("RequestId = " + response.getRequestId() + "\n");
}
