Question

我正在尝试构建一个用于将视频上传到YouTube的服务器应用程序。在我的服务器应用程序中，用户可以将视频直接上传到我的YouTube频道，以便将其公开。

enter image description here

我的应用程序的客户端部分获取视频并将其上传到我的服务器。
我的服务器然后使用YouTube API将视频上传到我的YouTube频道。

为了完成这项工作，我创建了一个虚拟Web应用程序，它可以捕获生成的刷新令牌，并将其存储在key.txt文件中

{"access_token":"MYTOKEN","token_type":"Bearer","expires_in":3600,"created":1435654774}

如果upload_video.php已过期，"key.txt"脚本将自动更新access_token文件。这是upload_video.php的代码：

$key = file_get_contents('key.txt');

$application_name = 'YouTube_Upload'; 
$client_secret    = 'MY_CLIENT_SECRET';
$client_id        = 'MY_CLIENT_ID';
$scope            = array('https://www.googleapis.com/auth/youtube.upload', 'https://www.googleapis.com/auth/youtube', 'https://www.googleapis.com/auth/youtubepartner');

$videoPath        = "Test.f4v";
$videoTitle       = "A tutorial video";
$videoDescription = "A video tutorial on how to upload to YouTube";
$videoCategory    = "22";
$videoTags        = array("youtube", "tutorial");

try{
    // Client init
    $client = new Google_Client();
    $client->setApplicationName($application_name);
    $client->setClientId($client_id);
    $client->setAccessType('offline');
    $client->setAccessToken($key);
    $client->setScopes($scope);
    $client->setClientSecret($client_secret);

    if ($client->getAccessToken()) {

        /**
         * Check to see if access token has expired. If so, get a new one and save it to file for future use.
         */
        if($client->isAccessTokenExpired()) {
            $newToken = json_decode($client->getAccessToken());
            $client->refreshToken($newToken->refresh_token);
            file_put_contents('key.txt', $client->getAccessToken());
        }

        $youtube = new Google_Service_YouTube($client);

        // Create a snipet with title, description, tags and category id
        $snippet = new Google_Service_YouTube_VideoSnippet();
        $snippet->setTitle($videoTitle);
        $snippet->setDescription($videoDescription);
        $snippet->setCategoryId($videoCategory);
        $snippet->setTags($videoTags);

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

        // Create a YouTube video with snippet and status
        $video = new Google_Service_YouTube_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;

        // Setting the defer flag to true tells the client to return a request which can be called
        // with ->execute(); instead of making the API call immediately.
        $client->setDefer(true);

        // Create a request for the API's videos.insert method to create and upload the video.
        $insertRequest = $youtube->videos->insert("status,snippet", $video);

        // Create a MediaFileUpload object for resumable uploads.
        $media = new Google_Http_MediaFileUpload(
            $client,
            $insertRequest,
            'video/*',
            null,
            true,
            $chunkSizeBytes
        );
        $media->setFileSize(filesize($videoPath));

        // Read the media file and upload it chunk by chunk.
        $status = false;
        $handle = fopen($videoPath, "rb");
        while (!$status && !feof($handle)) {
            $chunk = fread($handle, $chunkSizeBytes);
            $status = $media->nextChunk($chunk);
        }

        fclose($handle);

        /**
         * Video has successfully been upload
         */
        if ($status->status['uploadStatus'] == 'uploaded') {
            // Actions to perform for a successful upload
            // ......
        }

        // If want to make other calls after the file upload, set setDefer back to false
        $client->setDefer(true);

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

} catch(Google_Service_Exception $e) {
    print "Google_Service_Exception ".$e->getCode(). " message is ".$e->getMessage();
    print "Stack trace is ".$e->getTraceAsString();
}catch (Exception $e) {
    print "Exception ".$e->getCode(). " message is ".$e->getMessage();
    print "Stack trace is ".$e->getTraceAsString();
}

当脚本运行时，会引发此异常：

Exception 0 message is Failed to start the resume-able upload (HTTP 400: global, Uploads must be sent to the upload URL. Re-send this request to https://www.googleapis.com/upload/youtube/v3/videos?part=status,snippet&uploadType=resumable)Stack trace is 
#0 D:\xampp\htdocs\youtube\src\Google\Http\MediaFileUpload.php(136): Google_Http_MediaFileUpload->getResumeUri()

#2 {main}

getResumeUri()

异常加注，我有来自Google的var转储

Google_Http_MediaFileUpload

有什么问题？感谢您的帮助，对不起的英语感到抱歉。

Answer 1

这似乎是Google API的PHP客户端库的一个问题。转到GOOGLE_LIB_PATH / Http / MediaFileUpload.php并替换此行：

$this->request->setBaseComponent($base . '/upload');

有了这个：

$this->request->setBaseComponent($base . 'upload');

再试一次并分享结果。我遇到了与Google Pubsub API类似的问题，其中库设置的API路径不正确。

Answer 2

我希望你需要Resumable Uploads（https://developers.google.com/youtube/v3/guides/using_resumable_upload_protocol）

然后使用this而不做任何修改。

同时检查https://support.google.com/youtube/troubleshooter/2888402?hl=en

是否支持视频格式

Answer 3

有一种google方法来获取刷新令牌，因此不使用json_decode：

$newToken = json_decode($client->getAccessToken());
$client->refreshToken($newToken->refresh_token);

你可以这样做：

$client->refreshToken( $client->getRefreshToken() );

Answer 4

这是我到目前为止测试过的并且工作正常。

$key = trim(file_get_contents('key.txt'));
$scope = 'https://www.googleapis.com/auth/youtube';

PHP API Youtube上传，例外：无法启动可恢复上传，必须将上传发送到上传URL
