获取阿里云视频播放凭证接口

1、 在service_vod模块创建接口

在service_vod的com/ atguigu/vodservice/controller/VideoController里添加根据视频id获取视频播放凭证。

package com.atguigu.vodservice.controller;

import com.aliyuncs.DefaultAcsClient;
import com.aliyuncs.vod.model.v20170321.GetVideoPlayAuthRequest;
import com.aliyuncs.vod.model.v20170321.GetVideoPlayAuthResponse;
import com.atguigu.commonutils.R;
import com.atguigu.vodservice.utils.AliyunVodSDKUtils;
import com.atguigu.vodservice.utils.ConstantPropertiesUtil;
import io.swagger.annotations.Api;
import org.springframework.web.bind.annotation.*;

@Api(description="阿里云视频点播微服务")
@CrossOrigin //跨域
@RestController
@RequestMapping("/eduvod/video")
public class VideoController {

    @GetMapping("getplayauth/{videoId}")
    public R getVideoPlayAuth(@PathVariable("videoId") String videoId) throws Exception {

        //获取阿里云存储相关常量
        String accessKeyId = ConstantPropertiesUtil.ACCESS_KEY_ID;
        String accessKeySecret = ConstantPropertiesUtil.ACCESS_KEY_SECRET;

        //初始化
        DefaultAcsClient client = AliyunVodSDKUtils.initVodClient(accessKeyId, accessKeySecret);

        //请求
        GetVideoPlayAuthRequest request = new GetVideoPlayAuthRequest();
        request.setVideoId(videoId);

        //响应
        GetVideoPlayAuthResponse response = client.getAcsResponse(request);

        //得到播放凭证
        String playAuth = response.getPlayAuth();

        //返回结果
        return R.ok().message("获取凭证成功").data("playAuth", playAuth);
    }
}
