PHP API Youtube Uploads，异常: Failed to start the resumable upload, 上传必须发送到上传网址

Question

我正在尝试构建用于将视频上传到 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 channel 以将其公开。

1. 我的应用程序的客户端获取视频并将其上传到我的服务器。
2. 然后我的服务器使用 YouTube API 将视频上传到我的 YouTube channel 。

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

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

如果 access_token 已过期，upload_video.php 脚本将自动更新 "key.txt" 文件。这是来自 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，它引发了这个异常:

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

#2 {main}

Google_Http_MediaFileUpload 中 getResumeUri()(第 281 行)出现异常，我有 var dump 来自 google 的响应

怎么了？感谢您的帮助，抱歉英语不好。

这似乎是 Google API 的 PHP 客户端库的问题。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。我在使用 Google Pubsub API 时遇到了类似的问题，其中库设置的 API 路径不正确。
