使用谷歌api或任何其他方法从特定范围获取youtube频道视频

Question

我尝试使用谷歌api从播放列表中获取youtube视频。它成功了。但我最多可以获得50个视频。我需要做的是，获取50多个或从范围内获取最旧的视频。

就像我们可以在mysql中限制结果一样。

语言(PHP和Java脚本(

我的工作代码

<script src="https://apis.google.com/js/api.js"></script>
<script>
/**
* Sample JavaScript code for youtube.playlistItems.list
* See instructions for running APIs Explorer code samples locally:
* https://developers.google.com/explorer-help/guides/code_samples#javascript
*/
function loadClient() {
gapi.client.setApiKey("MY_API_KEY");
return gapi.client.load("https://www.googleapis.com/discovery/v1/apis/youtube/v3/rest")
.then(function() { console.log("GAPI client loaded for API"); },
function(err) { console.error("Error loading GAPI client for API", err); });
}
// Make sure the client is loaded before calling this method.
function execute() {
return gapi.client.youtube.playlistItems.list({
"part": "snippet,contentDetails",
"maxResults": 50,
"playlistId": "PLAY_LIST_ID"
})
.then(function(response) {
// Handle the results here (response.result has the parsed body).
console.log("Response", response);
},
function(err) { console.error("Execute error", err); });
}
gapi.load("client");
</script>

我阅读了谷歌api文档，并没有得到明确的答案。请不要结束提问。我需要明确的答案。
