阿里云视频点播

首先我们找到阿里云的PHP sdk 下载下来 我这里用的是2017-03-21版本的   php框架是Yii   前端Vue

下载下来之后将整个文件解压放到 vendor目录下  我在这里给文件夹改了个名 改成了aliyun-vod-upload-sdk    

在阿里云里需要新建一个用户  获取他的accessKeyId 和accessKeySecret，在这里记得给用户权限否则上传会报错

 

准备工作做完了，然后在Yii 控制器中    

/**

     * @Author   WangSai

    public function actionUploadVideo()
    {    require_once Yii::getAlias(\'@vendor\')."/aliyun-vod-upload-sdk/voduploadsdk/Autoloader.php"; //引入 autoloader 它会自动帮我们去引入我们需要的类
