我们正在使用youtube v3搜索API。我们在“totalResults”计数和response.items字段中返回的项目列表中不匹配。我在请求中请求了50个视频。返回的响应显示totalResults计为65但响应有效负载只有3个视频。
API:www.googleapis.com/youtube/v3/search/list
请求有效负载
{key=AIzaSyDXXQAtfbLwl6ZVoDDJPeeHKiWz3SzfOmM, maxResults=50, order=date, part=snippet, publishedAfter=2017-03-20T23:59:59.999-04:00, publishedBefore=2017-04-19T23:59:59.001-04:00, q=( ( "Wood Mackenzie" OR "Wood Mac" OR Woodmac OR @woodmackenzie ) AND NOT (fleetwood OR "fleet wood" OR 9WoodMac ) ) , type=video}
响应有效负载

答案 0 :(得分:3)
正如documentation本身所述,totalResults
是:
<强>整数强>
结果集中的结果总数。请注意,该值是近似值,可能不代表精确值。此外,最大值为1,000,000。
您不应使用此值来创建分页链接。而是使用 nextPageToken 和 prevPageToken 属性值来确定是否显示分页链接。
该值仅是近似值/估计值,但不是返回的items
总数的准确值。我使用与您相同的详细信息对API进行了测试,其值从63
变为64
和65
。
尽管如此,你的代码没有任何问题。这只是预期的行为。遗憾的是,totalResults
的值基于何处或最佳使用位置的地方没有说明。最好继续执行不依赖于此参数的实现。
