我试图搜索类似的东西，但没有找到任何相关的东西。我的问题是我尝试制作，因此当您搜索视频时，它第一次仅显示 8 个视频，然后每次单击"更多视频"时，它都会添加 8 个视频。猜测我在"maxResults"或/和"pageToken"上做错了什么。如果我在版本 3 中正确理解了 API，您只能显示 50 个视频，然后您需要转到另一个页面，有没有办法让它继续向下？任何帮助，不胜感激。

是的，CAqQAA是从 Youtube 返回的字符串。你把它放在$_GET数组中，在那里它找不到它。您必须使用$searchResponse['nextPageToken']进行pageToken.
您可以将其作为hidden值的形式放入<input type="hidden" name="token" value="<?php echo $searchResponse['nextPageToken']; ?>"/>
然后在你的第二个，如果你能做'pageToken' => $_GET['token']
