php - 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，允许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。

用户点击我网站上的一个按钮，将表单数据从隐藏的输入字段发送到一个运行 youtube 上传 api 脚本的新窗口，如果用户没有登录，它会要求他们登录。

我遇到的问题是，当用户必须登录并被重定向回页面时，帖子值丢失并导致我的上传脚本失败，因为它们应该定义视频路径。

我尝试了多种不同的方法来尝试传递变量，但是似乎没有任何效果，登录后数据永远不会传递到页面。

如果已经登录，它始终有效。当点击按钮时，变量被传递。

$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";

上面显示了我正在尝试的尝试，以便我可以定义 videoPath。我在尝试修改之前的原始脚本 --

<?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.

if ((user_can($current_user, "administrator"))||(user_can($current_user, "edit_others_posts")) ):


// Check to ensure that the access token was successfully acquired.

  try{
    // REPLACE this value with the path to the file you are uploading.
    $videoPath = $_SERVER["DOCUMENT_ROOT"] ."/uploads/".$authorID."/".$vidID."/output-".$vidID.".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->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);

    $media->setFileSize(filesize($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</li>',
        $status['snippet']['title']);

        htmlspecialchars($e->getMessage()));
  }
  $_SESSION[$tokenSessionKey] = $client->getAccessToken();

  $htmlBody = <<<END

那么如何在登录后将变量传递给页面。

Answer 1

您可以使用 sessionStorage 或 localStorage 来保存变量并在用户重定向回页面时检索它们。
