让用户将视频从我的站点服务器上传到他们的 youtube 频道

【中文标题】让用户将视频从我的站点服务器上传到他们的 youtube 频道【英文标题】：Let users upload videos from my site server to their youtube channel 【发布时间】：2019-02-17 14:14:15 【问题描述】：我正在运行一个带有 ffmpeg 的 WordPress 网站，我允许用户使用表单创建视频。视频运行良好，每个帖子都保存在自己的目录中。
我现在正尝试允许用户将他们创建的视频上传到他们自己的 youtube 频道。
使用来自youtube api 的 php 代码和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，为用户获取新令牌似乎可行，除了文件上传问题以及用户必须进入他们的 Google 帐户才能撤销访问/从我的站点应用程序中注销。

我很确定这与刷新或访问令牌有关。那么如何为每个用户创建一个访问令牌，而不是只允许我的帐户在应用程序上呢？
【问题讨论】：
【参考方案1】：通过在我的页面上使用以下表单，我能够让它按照我想要的方式工作 -
<form id="publish-youtube" action="/path/to/upload.php" method="post" target="_blank">
<input type="hidden" id="a_id" name="a_id" value="<?php echo $post_author_id; ?>" />
<input type="hidden" id="vid_id" name="vid_id" value="<?php echo $v_Id; ?>" />
<input type="submit" id="ytu_submit" name="ytu_submit" value="Publish to YouTube">
</form>
然后我按照youtube api docs 创建了我的应用程序和我的upload.php 脚本，该脚本要求用户登录（如果尚未登录）并根据表单中的值上传视频（注意：我使用wordpress） --

【讨论】：
【参考方案2】：你需要执行the OAUTH dance
Google 在此过程中有一些 good documentation。以下引用的内容和代码来自该站点。
您的应用程序确定它需要的权限。 您的应用程序将用户连同请求的权限列表一起重定向到 Google。 用户决定是否将权限授予您的应用程序。 您的应用程序会找出用户的决定。 如果用户授予请求的权限，您的应用程序将检索代表用户发出 API 请求所需的令牌。
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 以接受来自他们的回电，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令牌。
// 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();
然后您可以在您的 api 调用中使用该令牌代表用户进行调用。
