Question

我刚刚开始使用Youtube的v3 API而且我被困在某处应该使用分页但不知道该怎么做！

我只能使用nextpagetoken作为pagetoken转到下一页，但我无法返回上一页！

if (!empty($_GET['page'])) {
    $noPage = $_GET['page'];
    $page = ($noPage-1)*20;
    $pageToken = $_SESSION["nextToken"];
} else {
    $noPage = 1;
    $page = 1;
}
$searchResponse = $youtube->search->listSearch('id,snippet', array('q' => $q, 'maxResults' => $maxResults, 'type' => "video", 'pageToken' => $pageToken,));
if ($noPage > 1) {
    //echo'<a href="?page='.($noPage-1).'"><input type="submit" value="&laquo; Previous Page"/></a> - ';
    echo'<a href="'.$vhome.'search.html?q='.querydecode($q).'&amp;page='.$prev.'"><input type="submit" value="&laquo; Previous Page"/></a> - ';
}
if ($searchResponse['nextPageToken']) {
    //echo '<a href="?page='.($noPage+1).'"><input type="submit" value="Next Page &raquo;"/></a>';
    echo '<a href="'.$vhome.'search.html?q='.querydecode($q).'&amp;page='.$next.'"><input type="submit" value="Next Page &raquo;"/></a>';
}

第1页的搜索结果将包含＆＃34; nextPageToken＆＃39; ...如果你把它设置为＆＃39; pageToken＆＃39;参数，并保持查询中的所有其他参数相同，它将加载页面2.

// loads the first page of results
$searchResponse = $youtube->search->listSearch('id,snippet', array('q' => $q, 'maxResults' => $maxResults, 'type' => "video"));
// this gets page two of results
$newSearchResponse = $youtube->search->listSearch('id,snippet', array('q' => $q, 'maxResults' => $maxResults, 'type' => "video", 'pageToken' => $searchResponse["nextPageToken"]));

第二页还将包含一个＆＃39; nextPageToken＆＃39;您可以使用它转到第3页，但第2页也会返回＆＃39; prevPageToken＆＃39 ;;如果您设置了＆＃39; pageToken＆＃39;该值的参数并重新运行您的请求，您将再次从第1页获得结果。

// loads the third page of results
$newNewSearchResponse = $youtube->search->listSearch('id,snippet', array('q' => $q, 'maxResults' => $maxResults, 'type' => "video",'pageToken' => $newSearchResponse["nextPageToken"]));
// this goes back to page 1 of results
$oldSearchResponse = $youtube->search->listSearch('id,snippet', array('q' => $q, 'maxResults' => $maxResults, 'type' => "video", 'pageToken' => $newSearchResponse["prevPageToken"]));
