微信程序通过STS方式直接上传视频到阿里视频点播解决方案,这里必须批评下阿里云官方的文档写的实在是让人看不懂,是在太乱啦,阿里官方并没有提供微信小程序上传的SDK,然后这个小问题困扰了我两天的时间,下了好几次工单,然后自己一步一步摸索才解决的。

1、PHP后端代码,获取与刷新视频点播的权限信息以及上传地址

/**

     * [CreateUploadVideo 获取视频上传地址和凭证接口]

     */

    public function CreateUploadVideo() {

        if($this->request->isPost()){

    //获取参数

        $params = $this->request->param();


        //视频配置信息

        $this->userId = config('video.userId');

        $this->regionId = config('video.regionId');  // 点播服务接入区域

        $this->accessKeyId = config('video.accessKeyId');

        $this->accessKeySecret = config('video.accessKeySecret');

        $this->TemplateGroupId = config('video.TemplateGroupId'); //视频分组ID

        $this->TemplateGroupIdAudio = config('video.TemplateGroupIdAudio'); //音频分组ID

        $this->cateid = config('video.cateid'); //模板ID

        $this->StorageLocation = config('video.StorageLocation'); //存储位置


        //加载自动加载文件

        require_once env('extend_path') . 'voduploadsdk' . DIRECTORY_SEPARATOR . 'Autoloader.php';


        //实例化

        $profile = \DefaultProfile::getProfile($this->regionId, $this->accessKeyId, $this->accessKeySecret);

        $client = new \DefaultAcsClient($profile);


        //请求

        $request = new \vod\Request\V20170321\CreateUploadVideoRequest();

        $request->setTitle($params['title']);        // 视频标题(必填参数)

        $request->setFileName($params['fielname']); // 视频源文件名称,必须包含扩展名(必填参数)

        //$request->setDescription($params['remark']);  // 视频源文件描述(可选)

        //$request->setCoverURL(''); // 自定义视频封面(可选)

        //$request->setTags($params['tags']); // 视频标签,多个用逗号分隔(可选)

        $request->setCateId($this->cateid); //设置视频分类ID

        $request->setTemplateGroupId($this->TemplateGroupId); //转码模板组ID

        $res = $client->getAcsResponse($request);

            $res = (array) $res;

            if(!isset($res['VideoId']) || empty($res['VideoId'])){

                //返回数据

                $rdata['code'] = 0;

                $rdata['data'] = $res;

                $rdata['msg'] = '创建视频失败';

                return json($rdata);

            }

            $res['UploadAddress'] = json_decode(base64_decode($res['UploadAddress']), true);

            $res['UploadAddress']['host'] = "http://" . $res['UploadAddress']['Bucket'] . "." . str_replace(array("https://","http://"), '', $res['UploadAddress']['Endpoint']);

            $res['UploadAuth'] = json_decode(base64_decode($res['UploadAuth']), true);


        //返回数据

        $rdata['code'] = 1;

        $rdata['data'] = $res;

            $rdata['msg'] = '创建视频成功';

            return json($rdata);

    }

    }


    /**

     * [RefreshUploadVideo 刷新视频上传凭证接口]

     */

    public function RefreshUploadVideo() {

        if($this->request->isPost()){

    //获取参数

        $params = $this->request->param();


        //视频配置信息

        $this->userId = config('video.userId');

        $this->regionId = config('video.regionId');  // 点播服务接入区域

        $this->accessKeyId = config('video.accessKeyId');

        $this->accessKeySecret = config('video.accessKeySecret');

        $this->TemplateGroupId = config('video.TemplateGroupId'); //视频分组ID

        $this->TemplateGroupIdAudio = config('video.TemplateGroupIdAudio'); //音频分组ID

        $this->cateid = config('video.cateid'); //模板ID

        $this->StorageLocation = config('video.StorageLocation'); //存储位置


        //加载自动加载文件

        require_once env('extend_path') . 'voduploadsdk' . DIRECTORY_SEPARATOR . 'Autoloader.php';


        //查询视频详情

        $profile = \DefaultProfile::getProfile($this->regionId, $this->accessKeyId, $this->accessKeySecret);

        $client = new \DefaultAcsClient($profile);


        $request = new \vod\Request\V20170321\RefreshUploadVideoRequest();

        $request->setVideoId($params['video_id']);

        $res = $client->getAcsResponse($request);

            $res = (array) $res;

            if(!isset($res['VideoId']) || empty($res['VideoId'])){

                //返回数据

                $rdata['code'] = 0;

                $rdata['data'] = $res;

                $rdata['msg'] = '刷新视频失败';

                return json($rdata);

            }

            $res['UploadAddress'] = json_decode(base64_decode($res['UploadAddress']), true);

            $res['UploadAddress']['host'] = "http://" . $res['UploadAddress']['Bucket'] . "." . str_replace(array("https://","http://"), '', $res['UploadAddress']['Endpoint']);

            $res['UploadAuth'] = json_decode(base64_decode($res['UploadAuth']), true);


        //返回数据

        $rdata['code'] = 1;

        $rdata['data'] = $res;

            $rdata['msg'] = '刷新视频成功';

            return json($rdata);

    }

    }


2、返回的信息进行签名处理STS上传

//通过STS上传视频到阿里云demo

//1:首先调用点播的接口获取到uploadAuthUploadAddress这两个数值

//2:对上面两个信息进行base64解码,获取到上传用的STS信息,还有endpoint, objectkey等信息。使用base64解析UploadAuth字符串,可以得到json格式的上传凭证。使用base64解析UploadAddress字符串,可以得到json格式的上传地址。具体参考:https://help.aliyun.com/document_detail/55397.html?spm=a2c4g.11186623.6.594.CtPvo9,其中AccessKeyId、AccessKeySecret、SecurityToken和Expiration就是一对STS信息。

//3:利用web直传,选择本地视频去上传。另外注意一下,因为用的是STS的方式去上传的,表单域里面注意加上:x-oss-security-token 参数值就是解码出来的Token信息

//4.获取到uploadAuth和Address的接口是:https://help.aliyun.com/document_detail/55407.html?spm=a2c4g.11174283.6.630.A80tBD

//5.OSS 的post请求参数请看:https://help.aliyun.com/document_detail/31988.html?spm=5176.11065259.1996646101.searchclickresult.5cab18efejYjTT
