我正在使用 ffmpeg 运行一个 WordPress 网站，我允许用户使用表单创建视频。这些视频工作正常，每个帖子都保存在自己的目录中。
我现在正尝试让用户将他们创建的视频上传到他们自己的 youtube channel 。
使用来自 youtube api 的 PHP 代码，以及来自谷歌控制台的我的应用程序，我能够成功地将视频上传到我自己的帐户。它只要求我进行一次身份验证。
PHP代码--

我也成功地按照 javascript 示例从我的计算机上传，但文件存储在服务器上，所以这不是我想要的。
使用 javascript，为用户获取新 token 似乎可行，除了文件上传问题和用户必须进入他们的 Google 帐户以撤销访问/从我的站点应用程序注销。

我很确定它与刷新或访问 token 有关。那么我如何才能为每个用户创建一个访问 token ，而不是只允许我的帐户使用该应用程序？
最佳答案
您需要执行 the OAUTH dance
Google 有一些 good documentation在过程中。以下引用的内容和代码是从该站点提取的。
- Your application identifies the permissions it needs.
- Your application redirects the user to Google along with the list of requested permissions.
- The user decides whether to grant the permissions to your application.
- Your application finds out what the user decided.
- If the user granted the requested permissions, your application retrieves tokens needed to make API requests on the user's behalf.
步骤 1 和 2 的代码:
// setup client (step.1)
$client = new Google_Client();
$client->setAuthConfig('client_secret.json');
$client->addScope(GOOGLE_SERVICE_YOUTUBE::YOUTUBE_UPLOAD);
$client->setRedirectUri('http://' . $_SERVER['HTTP_HOST'] . '/oauth2callback.php');
$client->setAccessType('offline'); // offline access
$client->setIncludeGrantedScopes(true); // incremental auth
// get url and redirect (step.2)
$auth_url = $client->createAuthUrl();
header('Location: ' . filter_var($auth_url, FILTER_SANITIZE_URL));
exit();
您需要设置重定向 url 以接受来自他们的返回调用，格式如下:
[your_callback_url]/oauth2callback?state=state_parameter_passthrough_value&code=[code]&scope=[scope]
然后您从回调中提取详细信息并将它们交换为允许您上传的 token 。
// swap the code for a token (step.5)
// … do client setup first
// then auth with the code
$client->authenticate($_GET['code']);
// retrieve the token
$access_token = $client->getAccessToken();
然后您可以在 API 调用中使用该 token 代表用户进行调用。
