java - youTube 数据 API V3 - 使用 PublishedAfter 时搜索返回错误 400

Question

我正在通过 java 项目中的关键字运行搜索，与示例中的完全一样 -

https://developers.google.com/youtube/v3/code_samples/java#search_by_keyword

效果很好，但是当我在示例中添加 PublishedAfter 选项时search.setPublishedAfter(myDateTime);

它返回错误 400 消息": "Bad Request"

  YouTube.Search.List search = youtube.search().list("id,snippet");

  String apiKey = properties.getProperty("youtube.apikey");
  search.setKey(apiKey);
  search.setQ(queryTerm);
  search.setPublishedAfter(myDateTime) // the code works when removing this line

  search.setFields("items(id/kind,id/videoId,snippet/title,snippet/thumbnails/default/url)");
  search.setMaxResults(NUMBER_OF_VIDEOS_RETURNED);

  SearchListResponse searchResponse = search.execute();
  List<SearchResult> searchResultList = searchResponse.getItems();

我想使用 setPublishedAfter 选项

请帮忙谢谢

Youtube api v3 表示“publishedAfter 参数指示 API 响应应仅包含在指定时间之后创建的资源。该值是 RFC 3339 格式的日期时间值 (1970-01-01T00:00: 00Z)"因此，您的问题很可能是因为您的日期格式。查看您的“myDateTime”对象。错误应该接近它。另请查看我的代码:

Calendar cal = Calendar.getInstance();
Date currentDateOfAmerica=cal.getTime();
cal.set(12, cal.get(12)-1);
Date dateOneMinuteBefore=cal.getTime();
DateTime dt1 = new DateTime(dateOneMinuteBefore);
DateTime dt2 = new DateTime(currentDateOfAmerica);

search.setPublishedAfter(dt1);
search.setPublishedBefore(dt2);

这段代码设置搜索从现在到一分钟前上传的视频
