Question

我正在运行一个 ffmpeg 的WordPress网站，允许用户使用表单创建视频。视频工作正常，每个帖子都保存在自己的目录中。

我现在正试图允许用户将他们创建的视频上传到自己的YouTube频道。

使用youtube api中的PHP代码以及Google控制台中的我的应用程序，我能够将视频成功上传到自己的帐户中。它只要求我进行一次身份验证。

PHP代码-

s:815:"a:4:{i:0;a:7:{s:4:"date";s:10:"2018-03-08";s:4:"time";s:7:"1:00 am";s:8:"location";s:4:"test";s:12:"updated-name";s:7:"wpcargo";s:10:"updated-by";i:2;s:7:"remarks";s:1:"1";s:6:"status";s:16:"Shipment Left US";}i:1;a:7:{s:4:"date";s:10:"2018-03-08";s:4:"time";s:7:"1:00 am";s:8:"location";s:4:"test";s:12:"updated-name";s:7:"wpcargo";s:10:"updated-by";i:2;s:7:"remarks";s:1:"1";s:6:"status";s:10:"Processing";}i:2;a:7:{s:4:"date";s:10:"2018-09-12";s:4:"time";s:7:"7:27 pm";s:8:"location";s:4:"test";s:12:"updated-name";s:7:"wpcargo";s:10:"updated-by";i:2;s:7:"remarks";s:1:"1";s:6:"status";s:10:"In Transit";}i:3;a:7:{s:4:"date";s:10:"2018-09-12";s:4:"time";s:7:"7:31 pm";s:8:"location";s:10:"tofindthis";s:12:"updated-name";s:7:"wpcargo";s:10:"updated-by";i:2;s:7:"remarks";s:1:"1";s:6:"status";s:10:"In Transit";}}";

我也已经成功地能够遵循javascript示例从计算机上载文件，但是文件存储在服务器上，所以这不是我想要的。

使用javascript，似乎可以为用户获取新令牌，但文件上传问题除外，并且用户必须进入其Google帐户才能撤消对我的网站应用程序的访问/注销。

JS代码-

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访问令牌，而不是只允许我在应用程序上使用我的帐户？

Answer 1

您需要执行the OAUTH dance

Google在此过程中有good documentation。以下引用的内容和代码是从该站点提取的。

您的应用程序标识了所需的权限。

您的应用程序将用户与请求的权限列表一起重定向到Google。

用户决定是否向您的应用授予权限。

您的应用程序可以找出用户的决定。

如果用户授予了请求的权限，则您的应用程序将检索代表用户发出API请求所需的令牌。

第1步和第2步的代码

// 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();

您需要设置重定向网址，以接受来自他们的回叫，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，并将其交换为令牌，以便您上载。

// 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调用中使用该令牌代表用户进行调用。

Answer 2

通过使用页面上的以下表格，我可以按照自己的方式工作-

<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），并根据表格中的值上传视频（注意： wordpress）-

<?php

session_start();

$application_name = 'XXXX'; 
$OAUTH2_CLIENT_ID = 'XXXX';
$OAUTH2_CLIENT_SECRET = 'XXXX';

$videoTitle = $_POST['titlez'];
$authorID = $_POST['a_id'];
$vidID = $_POST['vid_id'];

$client = new Google_Client();
$client->setClientId($OAUTH2_CLIENT_ID);
$client->setClientSecret($OAUTH2_CLIENT_SECRET);
$client->setScopes('https://www.googleapis.com/auth/youtube');
$redirect = filter_var('https://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF'],
    FILTER_SANITIZE_URL);
$client->setRedirectUri($redirect);
$client->setAccessType("offline");
$client->setApprovalPrompt("force");

// Define an object that will be used to make all API requests.
$youtube = new Google_Service_YouTube($client);
// Check if an auth token exists for the required scopes
$tokenSessionKey = 'token-' . $client->prepareScopes();
if (isset($_GET['code'])) {
  if (strval($_SESSION['state']) !== strval($_GET['state'])) {
    die('The session state did not match.');
  }
  $client->authenticate($_GET['code']);
  $_SESSION[$tokenSessionKey] = $client->getAccessToken();
  header('Location: ' . $redirect);
