Question

我正在尝试构建一个允许用户将视频上传到我的频道的网络应用。

所以我认为我必须选择OAuth 2.0 for Server to Server Applications，正如它在那里所说的那样：

通常情况下，应用程序使用服务帐户 应用程序使用Google API处理其自己的数据而不是 用户数据。

所以我按照create a service account的步骤进行了操作。但在完成这些步骤并生成密钥和ID后，我收到了以下错误：

发生客户端错误：无法启动可恢复上传（HTTP 401：youtube.header，Unauthorized）

这是我的全部代码：

// Load 'Google/Client.php' and 'Google/Service/YouTube.php' with composer.
require_once __DIR__ . '/vendor/autoload.php';
session_start();

$client_email = 'xxx@developer.gserviceaccount.com';
$private_key = file_get_contents('xxx-74c6a50933e3.p12');
$scopes = array(
  'https://www.googleapis.com/auth/youtube.upload',
  'https://www.googleapis.com/auth/youtube',
  'https://www.googleapis.com/auth/youtubepartner'
);

$credentials = new Google_Auth_AssertionCredentials(
    $client_email,
    $scopes,
    $private_key
);

$client = new Google_Client();
$client->setAssertionCredentials($credentials);
if ($client->getAuth()->isAccessTokenExpired()) {
     $client->getAuth()->refreshTokenWithAssertion();
}

$htmlBody = '';

// Define an object that will be used to make all API requests.
$youtube = new Google_Service_YouTube($client);

$htmlBody = '';

// Check to ensure that the access token was successfully acquired.
if ($client->getAccessToken()) {
  try{
    // REPLACE this value with the path to the file you are uploading.
    $videoPath = "/home/xxx/Desktop/Vids/small.mp4";

    // Create a snippet with title, description, tags and category ID
    // Create an asset resource and set its snippet metadata and type.
    // This example sets the video's title, description, keyword tags, and
    // video category.
    $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);


    $htmlBody .= "<h3>Video Uploaded</h3><ul>";
    $htmlBody .= sprintf('<li>%s (%s)</li>',
        $status['snippet']['title'],
        $status['id']);

    $htmlBody .= '</ul>';

  } catch (Google_Service_Exception $e) {
    $htmlBody .= sprintf('<p>A service error occurred: <code>%s</code></p>',
        htmlspecialchars($e->getMessage()));
  } catch (Google_Exception $e) {
    $htmlBody .= sprintf('<p>An client error occurred: <code>%s</code></p>',
        htmlspecialchars($e->getMessage()));
  }

  $_SESSION['token'] = $client->getAccessToken();
} else {
  // If the user hasn't authorized the app, initiate the OAuth flow
  $state = mt_rand();
  $client->setState($state);
  $_SESSION['state'] = $state;

  $authUrl = $client->createAuthUrl();
  $htmlBody = <<<END
  <h3>Authorization Required</h3>
  <p>You need to <a href="$authUrl">authorize access</a> before proceeding.<p>
END;
}
?>

我错过了哪些想法？

Answer 1

我想我找到了article的答案。

步骤：

第1步。创建token.php（确保将其设置为777）。放置来自Google的代码示例 - https://developers.google.com/youtube/v3/code_samples/php#upload_a_video - 进行一些修改，如下所示：

变化：

count < capacity

要：

if (isset($_SESSION['token'])) {
  $client->setAccessToken($_SESSION['token']);
}

第2步。在浏览器上运行token.php。授予访问权限。然后你得到一个json输出：

if (isset($_SESSION['token'])) {
  $client->setAccessToken($_SESSION['token']);

  // @ref: http://www.whitewareweb.com/php-youtube-video-upload-google-api-oauth-2-0-v3/
  echo "Access Token: " . $_SESSION['token'];
}

将其另存为token.txt

第3步。使用与Google相同的示例代码创建upload.php，并进行以下修改：

一个。在upload.php的开头包含token.txt文件：

{
  "access_token": "xxxxt7YvjObwYx3DG4NRmfjiQ",
  "token_type": "Bearer",
  "expires_in": 3600,
  "refresh_token": "xxxxq5hzQTUapZ7zyRIHP7X_G8",
  "created": 1466238624
}

然后将$key = file_get_contents('token.txt');传递给$key：

new Google_Client()

两个。在 $OAUTH2_CLIENT_ID = 'xxxx.googleusercontent.com'; $OAUTH2_CLIENT_SECRET = 'xxxx'; // Client init $client = new Google_Client(); $client->setClientId($OAUTH2_CLIENT_ID); $client->setAccessType('offline'); $client->setApprovalPrompt('force'); $client->setAccessToken($key); $client->setClientSecret($OAUTH2_CLIENT_SECRET);之前的try catch部分中添加此代码：

$youtube = new Google_Service_YouTube($client);

第4步。运行upload.php即可。

您可以从该文章中获取整个代码。

Answer 2

我知道这听起来很奇怪，但前几天我遇到了同样的问题。我尝试了不同的事情......尝试更改YouTube类别ID ...

尝试将其更改为1，花了我几个小时进行故障排除，最终发现许多类别在YouTube PHP SDK中无效。

如果有效，可能想要对YouTube进行API调用并获取所有类别ID的列表，并单独尝试所有类别ID，直到找到有效的方式...有关如何执行此操作的文档位于： https://developers.google.com/youtube/v3/docs/videoCategories/list

这假设您的所有OAuth令牌都是正确的。
