aliyun 对象存储oos及视频点播

一.对象存储

1.准备

阿里云官网：/?spm=5176.12818093.nav-right.dofficial.488716d0lAQiWy

1.1 充几毛钱就行

1.2找到对象存储oos

1.3 免费开通，进入管理控制台，获取keyId和keySecret

1.4 创建bucket（拿到bucketName和Endpoint）

上述步骤可以拿到以下参数

		String endpoint =PropertiesUtils.END_POINT;String accessKeyId = PropertiesUtils.KEY_ID;String accessKeySecret = PropertiesUtils.KEY_SECRET;String bucketName = PropertiesUtils.BUCKET_NAME;

1.5 上传文件至对象存储oss（代码实现）

@Service
public class OssServiceImpl implements OssService {@Overridepublic String uploadFile(MultipartFile file) {String endpoint =PropertiesUtils.END_POINT;String accessKeyId = PropertiesUtils.KEY_ID;String accessKeySecret = PropertiesUtils.KEY_SECRET;String bucketName = PropertiesUtils.BUCKET_NAME;String url=null;try {OSS ossClient = new OSSClientBuilder().build(endpoint, accessKeyId, accessKeySecret);InputStream inputStream = file.getInputStream();String fileName = file.getOriginalFilename();ossClient.putObject("mario-plus", fileName, inputStream);ossClient.shutdown();url = "https://"+bucketName+"."+endpoint+"/"+fileName;} catch (IOException e) {e.printStackTrace();}return url;}
}

上述代码，通过endpoint, accessKeyId, accessKeySecret三个参数获取OSS对象，使用oss对象调用putObject( )方法上传文件，上传成功后需要自行组装url
url = “https://”+bucketName+"."+endpoint+"/"+fileName;
通过该url可以直接显示或下载文件

二. 视频点播

先踩一个坑：
上传视频的时候，需要阿里的一个依赖 aliyun-sdk-vod-upload，但是该jar并没有开源，所以要手动下载导入到maven仓库中才能正常使用
附上地址：.html?spm=a2c4g.11186623.6.1029.2dab6cecZfMGvO

导入jar进maven仓库参考 注意版本

上述解压过程同时会拿到上传视频参考文件

2.1 上传视频

@Testpublic void test(){UploadVideoRequest request = new UploadVideoRequest(keyId, keySecret, "fileName", filePath);request.setPartSize(2 * 1024 * 1024L);request.setTaskNum(1);UploadVideoImpl uploader = new UploadVideoImpl();UploadVideoResponse response = uploader.uploadVideo(request);System.out.print("RequestId=" + response.getRequestId() + "\n");  //请求视频点播服务的请求IDif (response.isSuccess()) {System.out.print("VideoId=" + response.getVideoId() + "\n");} else {/* 如果设置回调URL无效，不影响视频上传，可以返回VideoId同时会返回错误码。其他情况上传失败时，VideoId为空，此时需要根据返回错误码分析具体错误原因 */System.out.print("VideoId=" + response.getVideoId() + "\n");System.out.print("ErrorCode=" + response.getCode() + "\n");System.out.print("ErrorMessage=" + response.getMessage() + "\n");}}

2.2 点播视频

参考官网开发文档：.html?spm=a2c4g.11186623.6.909.1aaa24d8qlLJN0

初始化（获取DefaultAcsClient对象）

	    //使用AccessKey初始化,获取到client对象String regionId ="cn-shanghai";DefaultProfile profile = DefaultProfile.getProfile(regionId,keyId, keySecret);DefaultAcsClient client = new DefaultAcsClient(profile);

根据视频id获取播放地址

		GetPlayInfoRequest request = new GetPlayInfoRequest();request.setVideoId("cf45f43797b044cb834743ff0d1dd82d");//视频idGetPlayInfoResponse response = client.getAcsResponse(request);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());
