PHP Youtube API v3 – 直接上传 – 未经授权的消息

我正在使用服务帐户方案(https://developers.google.com/accounts/docs/OAuth2?hl=es&csw=1#scenarios),我解决了google-api-php-client库中的一些问题(读取p12文件并避免isAccessTokenExpired始终返回false).

<?php
/** Config */ 
$private_key_password = 'notasecret';
$private_key_file = 'xxxxxxxx-privatekey.p12';
$applicationName = 'xxxxx-youtube';
$client_secret = 'CLIENT_SECRET';
$client_id = 'xxxxxxxxxxxxx.apps.googleusercontent.com';
$service_mail = 'xxxxxxxxxxx@developer.gserviceaccount.com';
$public_key = 'xxxxxxxxxxx';

/** Constants */ 
$scope = 'https://www.googleapis.com/auth/youtube';
$url_youtube_token = 'https://accounts.google.com/o/oauth2/token';

/** Create and sign JWT */ 
$jwt = new Google_AssertionCredentials($service_mail,$scope,$private_key_file,$private_key_password,$url_youtube_token);
$jwt_assertion = $jwt->generateAssertion();

/** Use JWT to request token */
$data = array(
    'grant_type' => 'urn:ietf:params:oauth:grant-type:jwt-bearer','assertion' => $jwt_assertion,);

// use key 'http' even if you send the request to https://...
$options = array(
    'http' => array(
        'header'  => "Content-type: application/x-www-form-urlencodedrn",'method'  => 'POST','content' => http_build_query($data),),);

$context = stream_context_create($options);
$result = file_get_contents($url_youtube_token,false,$context);

那时我在json响应中得到了访问令牌,如下所示：

{
  "access_token" : "1/8xbJqaOZXSUZbHLl5EOtu1pxz3fmmetKx9W8CV4t79M","token_type" : "Bearer","expires_in" : 3600
}

没有“created”,“refresh_token”和“id_token”字段.所以我修改了Google_OAuth2类中的setAccessToken方法,如果没有设置,则将“created”字段设置为time().否则isAccessTokenExpired总是返回false.

现在,我们去上传文件.

try{
        // Client init 
        $client = new Google_Client();
        $client->setClientId($client_id);
        $client->setClientSecret($client_secret);
        $client->setApplicationName($applicationName);

        $client->setAccessToken($result);

        if ($client->getAccessToken()) {

            if($client->isAccessTokenExpired()) {
                // @TODO Log error 
                echo 'Access Token Expired!!<br/>'; // Debug
            }

            $youtube = new Google_YoutubeService($client);

            $videoPath = "./test.mp4";

            // Create a snipet with title,description,tags and category id
            $snippet = new Google_VideoSnippet();
            $snippet->setTitle("fmgonzalez test " . time());
            $snippet->setDescription("fmgonzalez test " . time() );
            $snippet->setTags(array("tag1","tag2"));

            // Numeric video category. See
            // https://developers.google.com/youtube/v3/docs/videoCategories/list
            $snippet->setCategoryId("22");

            // Create a video status with privacy status. Options are "public","private" and "unlisted".
            $status = new Google_VideoStatus();
            $status->privacyStatus = "public";

            // Create a YouTube video with snippet and status
            $video = new Google_Video();
            $video->setSnippet($snippet);
            $video->setStatus($status);

            // Size of each chunk of data in bytes. Setting it higher leads faster upload (less chunks,// for reliable connections). Setting it lower leads better recovery (fine-grained chunks)
            $chunkSizeBytes = 1 * 1024 * 1024;

            // Create a MediaFileUpload with resumable uploads
            $media = new Google_MediaFileUpload('video/*',null,true,$chunkSizeBytes);
            $media->setFileSize(filesize($videoPath));

            // Create a video insert request
            $insertResponse = $youtube->videos->insert("status,snippet",$video,array('mediaUpload' => $media));

            $uploadStatus = false;

            // Read file and upload chunk by chunk
            $handle = fopen($videoPath,"rb");
            $cont = 1;
            while (!$uploadStatus && !feof($handle)) {
                $chunk = fread($handle,$chunkSizeBytes);
                $uploadStatus = $media->nextChunk($insertResponse,$chunk);
                echo 'Chunk ' . $cont . ' uploaded <br/>';
                $cont++;
            }

            fclose($handle);

            echo '<br/>OK<br/>';

        }else{
            // @TODO Log error 
            echo 'Problems creating the client';
        }

    } catch(Google_ServiceException $e) {
        print "Caught Google service Exception ".$e->getCode(). " message is ".$e->getMessage(). " <br>";
        print "Stack trace is ".$e->getTraceAsString();
    }catch (Exception $e) {
        echo $e->getMessage();
    }

但是我收到“无法启动可恢复上传”消息.

调试,Google_MediaFileUpload中的方法getResumeUri我有这个响应体：

"error": {
    "errors": [
    {
        "domain": "youtube.header","reason": "youtubeSignupRequired","message": "Unauthorized","locationType": "header","location": "Authorization"
    }
    ],"code": 401,"message": "Unauthorized"
}

我找到了关于其他场景的示例,但没有找到关于此场景的示例.

我该怎么办才能最终上传视频文件？关于这种情况的任何例子？

提前致谢.
