PHP + Youtube API - 如何允许用户将视频上传到我自己的 channel ？

Question

我正在尝试构建一个允许用户将视频上传到我的 channel 的网络应用程序。

所以我想我必须去OAuth 2.0 for Server to Server Applications ，正如它在那里所说的那样:

Typically, an application uses a service account when the application uses Google APIs to work with its own data rather than a user's data.

所以我已经按照步骤 create a service account .但在完成这些步骤并生成 key 和 ID 后，我收到以下错误:

An client error occurred: Failed to start the resumable upload (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;
}
?>

<!doctype html>
<html>
<head>
<title>Video Uploaded</title>
</head>
<body>
  <?=$htmlBody?>
</body>
</html>

任何想法我错过了什么？

Answer 1

我想我从这个 article 中找到了答案.

脚步:

第 1 步。创建一个 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 - 稍作修改如下:

改变:

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

到:

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'];
}

第 2 步。在浏览器上运行 token.php。授予访问权限。然后你会得到下面的 json 输出:

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

将其保存为 token.txt

第三步。使用来自 Google 的相同示例代码创建 upload.php - 进行以下修改:

一。 在 upload.php 的开头包含 token.txt 文件:

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

然后通过$key进入 new Google_Client() :

$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);

二。 将此代码添加到 try catch 部分 之前 $youtube = new Google_Service_YouTube($client); :

    /**
     * Check to see if our 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('token.txt', $client->getAccessToken());
    }

第 4 步 .运行upload.php 就可以了。
