SpringBoot+阿里云OSS实现在线视频播放的示例

硕子鸽 人气:0

阿里云 OSS 是一种云存储技术，你可以理解为云盘，我们的目标是将视频存储到云端，然后在前端读取并播放视频。

OSS

首先登陆首页，创建一个存储桶：https://oss.console.aliyun.com


然后找到读写权限：


将读写权限设置为公共读即可：


在 RAM 中新建一个用户：


为其添加权限，选择 OSS 的权限：


然后点进去这个用户，找到 AccessKey：


创建之后记下来 secret ，因为他只出现一次，如果没记住也没事，可以重新创建新的 key。

下面开始编写服务端代码：

    appendObjectRequest.setPosition((long) ((shardIndex - 1) * shardSize));
    AppendObjectResult appendObjectResult = ossClient.appendObject(appendObjectRequest);

    String path = dir + "/" + key + "." + suffix;

    // 创建OSSClient实例。
    OSS ossClient = new OSSClientBuilder().build(endpoint, accessKeyId, accessKeySecret);
    PutObjectRequest putObjectRequest = new PutObjectRequest(bucket, path, new ByteArrayInputStream(file.getBytes()));
    ossClient.putObject(putObjectRequest);

    ResponseDto<FileDto> responseDto = new ResponseDto<>();
    FileDto fileDto = new FileDto();
    fileDto.setPath(ossDomain + path);

    return responseDto;
  }
}

这部分内容可以参考阿里云的帮助手册：https://help.aliyun.com/document_detail/32011.html?spm=a2c4g.11174283.6.915.443b7da2mfhbKq

上面写的是两个接口：

注意这里的参数都已经在 yml 文件中定义了：

上面的 KeyId 和 KeySecret 就是之前在创建用户时给的那两个，填上就行了。

在前端我们就可以发送请求获取数据，注意这里的对象是我自定义的，大家可以根据项目需求自行设置。

_this.$ajax.post(process.env.VUE_APP_SERVER + '/file/admin/oss-simple', formData).then(response => {
 Loading.hide();
 let resp = response.data;
 _this.afterUpload(resp);
 // 清空原来控件中的值
 $("#" + _this.inputId + "-input").val("");
})

视频点播

VOD 是另一种视频存储的形式，它的功能更丰。阿里云视频点播（VOD）是集音视频上传、自动化转码处理、媒体资源管理、分发加速于一体的全链路音视频点播服务。

我们同样需要一个 VOD 的用户，给它赋予 VOD 的权限：


SDK 的使用可以参考文档：https://help.aliyun.com/document_detail/61063.html?spm=a2c4g.11186623.6.921.418f192bTDCIJN

我们可以在转码组设置自己的模板，然后通过 ID 在代码中使用：


上传视频比较简单，和 OSS 很像，但是播放视频要多一个条件，在获取播放链接之前要先取得权限认证，所以下面单独写了一个 /get-auth/{vod} 接口，其中的参数就是 vod 的 ID，这个 ID 在我们上传视频之后会作为返回值返回的。

     encryptType: 1, //当播放私有加密流时需要设置。
    }, function (player) {
     console.log('播放器创建好了。')
    });
   } else {
    Toast.warning('播放错误。')
   }
  });
 }
},

上述的前端代码只是一个例子，playVod 调用的是阿里的播放器。
