【问题描述】：
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的是，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。 猜我在“maxResults”或/和“pageToken”上做错了什么。 如果我在版本 3 中正确理解 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？ 任何帮助表示赞赏。

【问题讨论】：
-
那么你得到了多少结果？你对
maxResult和pageToken的想法应该可行。 -
嗯，我得到了 8 个结果，但只有 8 个，不管我按“搜索”还是“更多视频”
-
$_GET['CAqQAA']究竟来自哪里？ -
如果您查看带有 $searchResponse 的 if 语句下方，您将看到
echo $searchResponse['nextPageToken'];它将输出CAqQAA -
好吧，我添加了我的下一条评论作为答案..
