SpringBoot+阿里雲OSS實現線上視訊播放的示例
阿里雲 OSS 是一種雲端儲存技術,你可以理解為雲盤,我們的目標是將視訊儲存到雲端,然後在前端讀取並播放視訊。
OSS
首先登陸首頁,建立一個儲存桶:https://oss.console.aliyun.com
然後找到讀寫許可權:
將讀寫許可權設定為公共讀即可:
在 RAM 中新建一個使用者:
為其新增許可權,選擇 OSS 的許可權:
然後點進去這個使用者,找到 AccessKey:
建立之後記下來 secret
,因為他只出現一次,如果沒記住也沒事,可以重新建立新的 key
。
下面開始編寫服務端程式碼:
POM
<!-- 阿里雲oss --> <dependency> <groupId>com.aliyun.oss</groupId> <artifactId>aliyun-sdk-oss</artifactId> <version>3.10.2</version> </dependency>
package com.lsu.file.controller.admin; import com.alibaba.fastjson.JSONObject; import com.aliyun.oss.OSS; import com.aliyun.oss.OSSClientBuilder; import com.aliyun.oss.model.AppendObjectRequest; import com.aliyun.oss.model.AppendObjectResult; import com.aliyun.oss.model.ObjectMetadata; import com.aliyun.oss.model.PutObjectRequest; import com.lsu.server.dto.FileDto; import com.lsu.server.dto.ResponseDto; import com.lsu.server.enums.FileUseEnum; import com.lsu.server.service.FileService; import com.lsu.server.util.Base64ToMultipartFile; import com.lsu.server.util.UuidUtil; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.beans.factory.annotation.Value; import org.springframework.web.bind.annotation.*; import org.springframework.web.multipart.MultipartFile; import javax.annotation.Resource; import java.io.ByteArrayInputStream; /** * @author wsuo */ @RestController @RequestMapping("/admin") public class OssController { private static final Logger LOG = LoggerFactory.getLogger(FileController.class); @Value("${oss.accessKeyId}") private String accessKeyId; @Value("${oss.accessKeySecret}") private String accessKeySecret; @Value("${oss.endpoint}") private String endpoint; @Value("${oss.bucket}") private String bucket; @Value("${oss.domain}") private String ossDomain; public static final String BUSINESS_NAME = "OSS檔案上傳"; @Resource private FileService fileService; @PostMapping("/oss-append") public ResponseDto<FileDto> fileUpload(@RequestBody FileDto fileDto) throws Exception { LOG.info("上傳檔案開始"); String use = fileDto.getUse(); String key = fileDto.getKey(); String suffix = fileDto.getSuffix(); Integer shardIndex = fileDto.getShardIndex(); Integer shardSize = fileDto.getShardSize(); String shardBase64 = fileDto.getShard(); MultipartFile shard = Base64ToMultipartFile.base64ToMultipart(shardBase64); FileUseEnum useEnum = FileUseEnum.getByCode(use); String dir = useEnum.name().toLowerCase(); String path = dir + "/" + key + "." + suffix; // 建立OSSClient例項。 OSS ossClient = new OSSClientBuilder().build(endpoint,accessKeyId,accessKeySecret); ObjectMetadata meta = new ObjectMetadata(); // 指定上傳的內容型別。 meta.setContentType("text/plain"); // 通過AppendObjectRequest設定多個引數。 AppendObjectRequest appendObjectRequest = new AppendObjectRequest(bucket,path,new ByteArrayInputStream(shard.getBytes()),meta); appendObjectRequest.setPosition((long) ((shardIndex - 1) * shardSize)); AppendObjectResult appendObjectResult = ossClient.appendObject(appendObjectRequest); // 檔案的64位CRC值。此值根據ECMA-182標準計算得出。 System.out.println(appendObjectResult.getObjectCRC()); System.out.println(JSONObject.toJSONString(appendObjectResult)); ossClient.shutdown(); LOG.info("儲存檔案記錄開始"); fileDto.setPath(path); fileService.save(fileDto); ResponseDto<FileDto> responseDto = new ResponseDto<>(); fileDto.setPath(ossDomain + path); responseDto.setContent(fileDto); return responseDto; } @PostMapping("/oss-simple") public ResponseDto<FileDto> fileUpload(@RequestParam MultipartFile file,String use) throws Exception { LOG.info("上傳檔案開始"); FileUseEnum useEnum = FileUseEnum.getByCode(use); String key = UuidUtil.getShortUuid(); String fileName = file.getOriginalFilename(); String suffix = fileName.substring(fileName.lastIndexOf(".") + 1).toLowerCase(); String dir = useEnum.name().toLowerCase(); String path = dir + "/" + key + "." + suffix; // 建立OSSClient例項。 OSS ossClient = new OSSClientBuilder().build(endpoint,accessKeySecret); PutObjectRequest putObjectRequest = new PutObjectRequest(bucket,new ByteArrayInputStream(file.getBytes())); ossClient.putObject(putObjectRequest); ResponseDto<FileDto> responseDto = new ResponseDto<>(); FileDto fileDto = new FileDto(); fileDto.setPath(ossDomain + path); responseDto.setContent(fileDto); return responseDto; } }
這部分內容可以參考阿里雲的幫助手冊:https://help.aliyun.com/document_detail/32011.html?spm=a2c4g.11174283.6.915.443b7da2mfhbKq
上面寫的是兩個介面:
- 追加上傳:
/oss-append
- 簡單上傳:
/oss-simple
注意這裡的引數都已經在 yml
檔案中定義了:
上面的 KeyId 和 KeySecret 就是之前在建立使用者時給的那兩個,填上就行了。
在前端我們就可以傳送請求獲取資料,注意這裡的物件是我自定義的,大家可以根據專案需求自行設定。
_this.$ajax.post(process.env.VUE_APP_SERVER + '/file/admin/oss-simple',formData).then(response => { Loading.hide(); let resp = response.data; _this.afterUpload(resp); // 清空原來控制元件中的值 $("#" + _this.inputId + "-input").val(""); })
視訊點播
VOD 是另一種視訊儲存的形式,它的功能更豐。阿里雲視訊點播(VOD)是集音視訊上傳、自動化轉碼處理、媒體資源管理、分發加速於一體的全鏈路音視訊點播服務。
我們同樣需要一個 VOD 的使用者,給它賦予 VOD 的許可權:
SDK 的使用可以參考文件:https://help.aliyun.com/document_detail/61063.html?spm=a2c4g.11186623.6.921.418f192bTDCIJN
我們可以在轉碼組設定自己的模板,然後通過 ID 在程式碼中使用:
上傳視訊比較簡單,和 OSS 很像,但是播放視訊要多一個條件,在獲取播放連結之前要先取得許可權認證,所以下面單獨寫了一個 /get-auth/{vod}
介面,其中的引數就是 vod 的 ID,這個 ID 在我們上傳視訊之後會作為返回值返回的。

methods: { playUrl(url) { let _this = this; console.log("開始播放:",url); // 如果已經有播放器了 就將播放器刪除 if (_this.aliPlayer) { _this.aliPlayer = null; $("#" + _this.playerId + '-player').remove(); } // 初始化播放器 $("#" + _this.playerId).append("<div class=\"prism-player\" id=\"" + _this.playerId + "-player\"></div>"); _this.aliPlayer = new Aliplayer({ id: _this.playerId + '-player',width: '100%',autoplay: true,//支援播放地址播放,此播放優先順序最高 source: url,cover: 'http://liveroom-img.oss-cn-qingdao.aliyuncs.com/logo.png' },function (player) { console.log("播放器建立好了") }) },playVod(vod) { let _this = this; Loading.show(); _this.$ajax.get(process.env.VUE_APP_SERVER + '/file/admin/get-auth/' + vod).then((response) => { Loading.hide(); let resp = response.data; if (resp.success) { //如果已經有播放器了,則將播放器div刪除 if (_this.aliPlayer) { _this.aliPlayer = null; $("#" + _this.playerId + '-player').remove(); } // 初始化播放器 $("#" + _this.playerId).append("<div class=\"prism-player\" id=\"" + _this.playerId + "-player\"></div>"); _this.aliPlayer = new Aliplayer({ id: _this.playerId + '-player',autoplay: false,vid: vod,playauth: resp.content,cover: 'http://liveroom-img.oss-cn-qingdao.aliyuncs.com/logo.png',encryptType: 1,//當播放私有加密流時需要設定。 },function (player) { console.log('播放器建立好了。') }); } else { Toast.warning('播放錯誤。') } }); } },
上述的前端程式碼只是一個例子,playVod
呼叫的是阿里的播放器。
