无法获取使用页面令牌的第二页搜索令牌youtube api搜索

嗨，朋友正在尝试使用youtube api v3搜索获取所有结果。这里是代码..无法获取使用页面令牌的第二页搜索令牌youtube api搜索

<!doctype html> 
    <html> 
    <head> 
     <title>Search</title> 
    </head> 
    <body> 
    <div id="buttons"> 
     <label> <input id="query" value='cats' type="text"/><button id="search-button" onclick="search()">Search</button></label> 
</div> 
<div id="search-container"> 
</div> 
    <button id="prev-button" class="paging-button" onclick="previousPage(document.getElementById('query').value);">Previous Page</button> 
    <button id="next-button" class="paging-button" onclick="nextPage(document.getElementById('query').value);">Next Page</button><br><br> 
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script> 
<script src="search.js"></script> 
<script src="https://apis.google.com/js/client.js?onload=googleApiClientReady"></script> 
</body>

这里是脚本代码..

var search,nextPageToken, prevPageToken; 

function search(pageToken) { 
    var q = $('#query').val(); 
    gapi.client.load('youtube', 'v3', function() { 
    gapi.client.setApiKey('Api-key'); 
    var request = gapi.client.youtube.search.list({ 
    q: q, 
    part: 'snippet', 
    type: 'playlist', 
    maxResults: 50, 
    order: 'viewCount' 
    }); 
     if (pageToken) { 
     request.pageToken = pageToken; 
    } 
    request.execute(function(response) { 
     nextPageToken = response.result.nextPageToken; 
    var nextVis = nextPageToken ? 'visible' : 'hidden'; 
    $('#next-button').css('visibility', nextVis); 
    prevPageToken = response.result.prevPageToken 
    var prevVis = prevPageToken ? 'visible' : 'hidden'; 
    $('#prev-button').css('visibility', prevVis); 
     var playlistItems = response.result.items; 
     if (playlistItems) { 
     $.each(playlistItems, function(index, item) { 
     displayResult(item.id); 
     }); 
     } else { 
     $('#search-container').html('Sorry you have no uploaded videos'); 
     } 
     }); 
    }); 
    } 
    function displayResult(videoSnippet) { 
     var title = videoSnippet.playlistId; 
     $('#search-container').append(title + '<br>'); 
     } 


    function nextPage(val) {; 
     var search_val=val; 
     search(nextPageToken,search_val); 
     } 

    // Retrieve the previous page of videos in the playlist. 
    function previousPage(listid) { 
     var search=listid; 
     search(prevPageToken,search); 
    }

我试图获取使用pagetokens的所有结果，但我不能把所有的结果我得到我同样的50个结果repeatedly..How可以得到使用搜索

要使用pageToken参数确切的结果，你应该在这里把您在得到字符串代码你的第一组结果。

例如，我用Search: list与这些参数：

- part: snippet 
- maxResults: 6 
- order: viewCount 
- type: playlist

https://developers.google.com/apis-explorer/#p/youtube/v3/youtube.search.list?part=snippet&maxResults=6&order=viewCount&type=playlist&_h=4&

下面是结果

流行音乐视频
热门ñ嗷嗷 - 俄罗斯
热门眼下
英国官方40强单曲榜 - 2017" 年2月4日
重要的视频
热门音乐2017年 - 最好的歌曲播放列表

现在，如果我们使用maxResults: 3在这个请求中，我们得到了预期的前3个。

https://developers.google.com/apis-explorer/#p/youtube/v3/youtube.search.list?part=snippet&maxResults=3&order=viewCount&type=playlist&_h=2&

您将在上述结果的参数的“nextPageToken”注意到：“CAMQAA”，这是你需要在你的下一个请求供应串码拿到下一页，或者在这个例子中得到接下来的三个结果：

    "liveBroadcastContent": "none" 
    } 
    } 
] 
}

然后再次使用"nextPageToken": string获得下一个页面结果。

希望这些信息对您有所帮助。
