我在授權(quán)某些請(qǐng)求時(shí)遇到問(wèn)題，并且收到 401“無(wú)效憑據(jù)”錯(cuò)誤。申請(qǐng)流程如下。用戶使用 Google 登錄按鈕登錄我的網(wǎng)站。我正在使用離線訪問(wèn)參數(shù)，并且正在會(huì)話中保存刷新令牌。用戶登錄后，我試圖從他們的 YouTube 帳戶中檢索他們所有的播放列表（公共和私人）。$client->setScopes('https://www.googleapis.com/auth/youtube.readonly');if (isset($_SESSION['googletoken']['refresh_token'])){$client->setAccessToken($_SESSION['googletoken']['refresh_token']);}$tokenSessionKey = $client->prepareScopes();$params = ['maxResults' => 1,'mine' => true];try{ $queryParams = [ 'maxResults' => 1, 'mine' => true]; $listResponse = $youtube->playlists->listPlaylists('snippet', $queryParams);
