项目引入阿里云视频点播PHP-SDK

背景：2021年乐视云的点播将停止提供服务，项目决定选择选用阿里云的视频的点播。在上线前，需要将之前的视频提前导入资源库，URLS方式拉取是比较方便的，对编辑同事来说操作简单，而且乐视云提供视频下载url，下面是对案例进行的调整

URL批量拉取上传（调整为多个视频上传）

阿里云PHP-SDK文档示例内容如下：点击地址进入 调用UploadMediaByURL接口，完成URL批量拉取上传功能。

接口参数和返回字段请参见UploadMediaByURL。调用示例如下：

/**
 * URL批量拉取上传
 * @param client 发送请求客户端
 * @return UploadMediaByURLResponse URL批量拉取上传响应数据
 */
function uploadMediaByURL($client) {
    $request = new vod\UploadMediaByURLRequest();
    $url = "http://192.168.0.0/16/***.mp4";
    $request->setUploadURLs($url);

    $uploadMetadataList = array();
    $uploadMetadata = array();
    $uploadMetadata["SourceUrl"] = $url;
    $uploadMetadata["Title"] = "upload by url sample";
    $uploadMetadataList[] = $uploadMetadata;
    $request->setUploadMetadatas(json_encode($uploadMetadataList));

    return $client->getAcsResponse($request);
}

try {
    $client = initVodClient('<AccessKeyId>', '<AccessKeySecret>');

    $result = uploadMediaByURL($client);
    var_dump($result);
} catch (Exception $e) {
    print $e->getMessage()."\n";
}

根据阿里云VOD的api文档，点击地址进入。

对于UploadURLs这个参数的描述是： URL中需要包括扩展名, 比如https://****.mp4中mp4为扩展名。 如果URL中不包含扩展名，可以在UploadMetadatas中传入FileExtension来指定。 如果URL中有扩展名且同时传入FileExtension，以传入的FileExtension为准。 指定支持的扩展名，请参见上传概述。 ==URL编码，多个地址以英文逗号（,）分隔，最多支持20个。 避免存在特殊字符导致无法上传视频，需要URL编码后再做逗号拼接。==

所以我们将示例代码进行下面的调整：

/**
 * URL批量拉取上传
 * @param client 发送请求客户端
 * @return UploadMediaByURLResponse URL批量拉取上传响应数据
 */
function uploadMediaByURL($client) {
   $request = new vod\UploadMediaByURLRequest();
   $urlDates = [];
   $uploadMetadataList = array();
   $uploadUrls = '';
   foreach ($urlDates as $urlDate){
       $url = urlencode($urlDate['url']);
       $uploadMetadata = array();
        $uploadMetadata["SourceUrl"] = $url;
        $uploadMetadata["Title"] = $urlDate['video_name'];
        $uploadMetadata["CateId"] = 123;
        $uploadMetadata["FileExtension"] = pathinfo($url, PATHINFO_EXTENSION);
        $uploadUrls .= $url.',';
        $uploadMetadataList[] = $uploadMetadata;
    }
    $uploadUrls = rtrim($uploadUrls, ",");
    $request->setUploadURLs($uploadUrls);
    $request->setUploadMetadatas(json_encode($uploadMetadataList));

	return $client->getAcsResponse($request);
}

try {
    $client = initVodClient('<AccessKeyId>', '<AccessKeySecret>');

    $result = uploadMediaByURL($client,);
    var_dump($result);
} catch (Exception $e) {
    print $e->getMessage()."\n";
}

相信这时候你已经明白了，我自己集成的类里的方法如下，供大家再参考下：

/**
     * URL批量拉取上传
     * @param client 发送请求客户端
     * @return UploadMediaByURLResponse URL批量拉取上传响应数据
     */
    private function uploadMediaByURL($client,$urlDates) {
        $request = new vod\UploadMediaByURLRequest();
        $uploadMetadataList = array();
        $uploadUrls = '';
        foreach ($urlDates as $urlDate){
            $url = urlencode($urlDate['url']);
            $uploadMetadata = array();
            $uploadMetadata["SourceUrl"] = $url;
            $uploadMetadata["Title"] = $urlDate['video_name'];
            $uploadMetadata["CateId"] = *****;
            $uploadMetadata["FileExtension"] = pathinfo($url, PATHINFO_EXTENSION);
            $uploadUrls .= $url.',';
            $uploadMetadataList[] = $uploadMetadata;
        }
        $uploadUrls = rtrim($uploadUrls, ",");
        $request->setUploadURLs($uploadUrls);
        $request->setUploadMetadatas(json_encode($uploadMetadataList));

        return $client->getAcsResponse($request);
    }

    public function uploadMediaByURLResult($urlDates)
    {
        try {
            $client = $this->initVodClient();
            $result = $this->uploadMediaByURL($client,$urlDates);

            return $result;
        } catch (Exception $e) {
            print $e->getMessage()."\n";
        }
    }
