如何在提示登录后将$ _POST数据传递给youtube上传脚本

Question

我的wordpress页面上有一个脚本,可让用户在我的网站上创建视频帖子,然后将视频上传到他们的YouTube.

用户单击我站点上的一个按钮,该按钮将表单数据从隐藏的输入字段发送到运行youtube上传api脚本的新窗口,如果用户未登录则要求他们这样做.

我遇到的问题是,当用户必须登录并重定向回页面时,帖子值会丢失并导致我的上传脚本失败,因为他们假定要定义视频路径.

我已经尝试了多次尝试以不同方式尝试并传递变量,但似乎没有任何工作,数据在登录后永远不会传递给页面.

如果已经登录,它总是有效.单击按钮时,变量将被传递.

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


$dirpath = $_SERVER["DOCUMENT_ROOT"] ."/wp-content/uploads/".$authorID."/".$vidID;

// Set session variables
$_SESSION["favcolor"] = $_POST['vid_id'];

file_put_contents($dirpath."/videoTitle.txt", $videoTitle);
file_put_contents($dirpath."/authorID.txt", $authorID);
file_put_contents($dirpath."/vidID.txt", $vidID);
file_put_contents($dirpath."/dir.txt", $dirpath);

$vID = file_get_contents($dirpath.'/vidID.txt');
$auID = file_get_contents($dirpath.'/authorID.txt');

// Check to ensure that the access token was successfully acquired.
if ($client->getAccessToken()) {
  $htmlBody = '';
  $htmlBody2 = '';
  try{

    // REPLACE this value with the path to the file you are uploading.
    $videoPath = $_SERVER["DOCUMENT_ROOT"] ."/wp-content/uploads/".$auID."/". $vID."/output-".$vID.".mp4";

上面显示了我尝试的尝试,以便我可以定义videoPath.我尝试修改前的原始脚本 -

<?php
//require_once $_SERVER['DOCUMENT_ROOT'] . '/gap/google-api-php-client/vendor/autoload.php';
require_once $_SERVER['DOCUMENT_ROOT'] . '/wp-load.php';

set_include_path($_SERVER['DOCUMENT_ROOT'] . '/gap/google-api-php-client/');
require_once 'src/Google/Client.php';
require_once 'src/Google/Service/YouTube.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: ' . $redirect);
}
if (isset($_SESSION[$tokenSessionKey])) {
  $client->setAccessToken($_SESSION[$tokenSessionKey]);
}

get_header();
global $current_user, $imic_options; // Use global
get_currentuserinfo(); // Make sure global is set, if not set it.

    // Create a snippet with title, description, tags and category ID

    $snippet->setCategoryId("22");

    // "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);

    $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</li>',

那么如何在登录后将变量传递给页面.

Answer 1

我想通了，并用sessionStorage解决了这个问题。我第一次尝试时它不起作用的原因是因为我的代码在脚本中的位置。通过移动 $_session 代码，我可以设置它。

我将其从脚本顶部移至脚本中的以下位置 -

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

$authorID = $_POST['a_id'];
$videoTitle = $_POST['ytu_title'];

// Set session variables
$_SESSION["video"] = $_POST['vid_id'];
$_SESSION["author"] = $_POST['a_id'];
$_SESSION["title"] = $_POST['ytu_title'];    
$vidID = $_SESSION["video"];

  $authUrl = $client->createAuthUrl();

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

在 youtube 脚本中查找此内容 -

// 如果用户尚未授权应用程序，则启动 OAuth 流程

这是脚本的一部分，如果用户尚未登录，则提示用户登录。因此这是他们看到的第一页，因此请确保在此处设置变量。

然后我就可以在脚本的其他部分使用变量 -

$videoPath = $_SERVER["DOCUMENT_ROOT"] ."/wp-content/uploads/" . $_SESSION["author"] . "/" . $_SESSION["video"] . "/output-" . $_SESSION["video"] . ".mp4";

$snippet->setTitle($_SESSION["title"]);
