使用Youtube API V3和PHP将视频上传到Youtube

我正在尝试使用PHP将视频上传到Youtube . 我正在使用Youtube API v3,我正在使用最新检出的Google API PHP客户端库源代码 .
我正在使用给出的示例代码
https://code.google.com/p/google-api-php-client/执行身份验证 . 身份验证很顺利,但是当我尝试上传视频时,我得到 Google_ServiceException ,错误代码为500,消息为null .

我看了之前提到的以下问题:Upload video to youtube using php client library v3但是接受的答案没有描述如何指定要上传的文件数据 .
我发现了另一个类似的问题Uploading file with Youtube API v3 and PHP,其中在评论中提到categoryId是强制性的,因此我尝试在片段中设置categoryId,但它仍然给出相同的异常 .

我还提到了文档站点上的Python代码(https://developers.google.com/youtube/v3/docs/videos/insert),但我在客户端库中找不到函数next_chunk . 但我试图在循环(在代码片段中提到)重试获取错误代码500,但在所有10次迭代中我得到相同的错误 .

以下是我正在尝试的代码段:

$youTubeService = new Google_YoutubeService($client);
if ($client->getAccessToken()) {
    print "Successfully authenticated";
    $snippet = new Google_VideoSnippet();
    $snippet->setTitle = "My Demo title";
    $snippet->setDescription = "My Demo descrition";
    $snippet->setTags = array("tag1","tag2");
    $snippet->setCategoryId(23); // this was added later after refering to another question on stackoverflow

    $status = new Google_VideoStatus();
    $status->privacyStatus = "private";

    $video = new Google_Video();
    $video->setSnippet($snippet);
    $video->setStatus($status);

    $data = file_get_contents("video.mp4"); // This file is present in the same directory as the code
    $mediaUpload = new Google_MediaFileUpload("video/mp4",$data);
    $error = true;
    $i = 0;

    // I added this loop because on the sample python code on the documentation page
    // mentions we should retry if we get error codes 500,502,503,504
    $retryErrorCodes = array(500, 502, 503, 504);
    while($i < 10 && $error) {
        try{
            $ret = $youTubeService->videos->insert("status,snippet", 
                                                   $video, 
                                                   array("data" => $data));

            // tried the following as well, but even this returns error code 500,
            // $ret = $youTubeService->videos->insert("status,snippet", 
            //                                        $video, 
            //                                        array("mediaUpload" => $mediaUpload); 
            $error = false;
        } catch(Google_ServiceException $e) {
            print "Caught Google service Exception ".$e->getCode()
                  . " message is ".$e->getMessage();
            if(!in_array($e->getCode(), $retryErrorCodes)){
                break;
            }
            $i++;
        }
    }
    print "Return value is ".print_r($ret,true);

    // We're not done yet. Remember to update the cached access token.
    // Remember to replace $_SESSION with a real database or memcached.
    $_SESSION['token'] = $client->getAccessToken();
} else {
    $authUrl = $client->createAuthUrl();
    print "<a href='$authUrl'>Connect Me!</a>";
}

这是我做错了吗?

    答案是通过Google PHP client libraries使用Google_Http_MediaFileUpload .

    这是示例代码:https://github.com/youtube/api-samples/blob/master/php/resumable_upload.php

    我能够使用以下代码使上传工作:

    if($client->getAccessToken()) {
        $snippet = new Google_VideoSnippet();
        $snippet->setTitle("Test title");
        $snippet->setDescription("Test descrition");
        $snippet->setTags(array("tag1","tag2"));
        $snippet->setCategoryId("22");
    
        $status = new Google_VideoStatus();
        $status->privacyStatus = "private";
    
        $video = new Google_Video();
        $video->setSnippet($snippet);
        $video->setStatus($status);
    
        $error = true;
        $i = 0;
    
        try {
            $obj = $youTubeService->videos->insert("status,snippet", $video,
                                             array("data"=>file_get_contents("video.mp4"), 
                                            "mimeType" => "video/mp4"));
        } catch(Google_ServiceException $e) {
            print "Caught Google service Exception ".$e->getCode(). " message is ".$e->getMessage(). " <br>";
            print "Stack trace is ".$e->getTraceAsString();
        }
    }

    我也意识到这是旧的, but 因为我从GitHub克隆了最新版本的php-client,我遇到了麻烦 Google_Service_YouTube_Videos_Resource::insert() -method .

    我会传递一个数组,其中 "data" => file_get_contents($pathToVideo)"mimeType" => "video/mp4" 设置为 insert() -method的参数,但我仍然继续获得 (400) BadRequest .

    通过 \Google\Service\Resource.php 中找到的Google代码进行调试和阅读,对数组密钥 "uploadType" 进行了检查(在第179-180行),这将启动Google_Http_MediaFielUpload对象 .

    $part = 'status,snippet';
    $optParams = array(
        "data" => file_get_contents($filename),
        "uploadType" => "media",  // This was needed in my case
        "mimeType" => "video/mp4",
    );
    $response = $youtube->videos->insert($part, $video, $optParams);
    

    如果我没记错的话,使用PHP-api的0.6版本就不需要uploadType参数 . 这可能仅适用于直接上传样式,而不适用于任何一天的答案中显示的可恢复上传 .

    我意识到这是旧的,但这是文档的答案:

    // REPLACE this value with the path to the file you are uploading.
        $videoPath = "/path/to/file.mp4";
    
        $snippet = new Google_Service_YouTube_VideoSnippet();
        $snippet->setTitle("Test title");
        $snippet->setDescription("Test description");
        $snippet->setTags(array("tag1", "tag2"));
    
        // Numeric video category. See
        // https://developers.google.com/youtube/v3/docs/videoCategories/list 
        $snippet->setCategoryId("22");
    
        // Set the video's status to "public". Valid statuses are "public",
        // "private" and "unlisted".
        $status = new Google_Service_YouTube_VideoStatus();
        $status->privacyStatus = "public";
    
        // Associate the snippet and status objects with a new video resource.
        $video = new Google_Service_YouTube_Video();
        $video->setSnippet($snippet);
        $video->setStatus($status);
    
        // Specify the size of each chunk of data, in bytes. Set a higher value for
        // reliable connection as fewer chunks lead to faster uploads. Set a lower
        // value for better recovery on less reliable connections.
        $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);
    
        // If you want to make other calls after the file upload, set setDefer back to false
        $client->setDefer(false);
