按时间间隔查询数据 MongoDB
-
有个问题想请求，数据库表中的数据如何按一定时间间隔提取数据，
数据如下：
{ "_id" : ObjectId("5a39c32aff6583393c37d981"), "uploadDate" : ISODate("2017-12-20T01:55:54Z"), "A" : "1" }
{ "_id" : ObjectId("5a39c32aff6583393c37d982"), "uploadDate" : ISODate("2017-12-20T01:55:55Z"), "A" : "1" }
{ "_id" : ObjectId("5a39c32aff6583393c37d983"), "uploadDate" : ISODate("2017-12-20T01:55:56Z"), "A" : "1" }
{ "_id" : ObjectId("5a39c32aff6583393c37d984"), "uploadDate" : ISODate("2017-12-20T01:55:57Z"), "A" : "1" }
{ "_id" : ObjectId("5a39c32aff6583393c37d988"), "uploadDate" : ISODate("2017-12-20T01:56:01Z"), "A" : "1" }
{ "_id" : ObjectId("5a39c32aff6583393c37d989"), "uploadDate" : ISODate("2017-12-20T01:56:02Z"), "A" : "1" }
{ "_id" : ObjectId("5a39c32aff6583393c37d98a"), "uploadDate" : ISODate("2017-12-20T01:56:03Z"), "A" : "1" }
{ "_id" : ObjectId("5a39c32aff6583393c37d98b"), "uploadDate" : ISODate("2017-12-20T01:56:04Z"), "A" : "1" }
{ "_id" : ObjectId("5a39c32aff6583393c37d98c"), "uploadDate" : ISODate("2017-12-20T01:56:05Z"), "A" : "1" }
{ "_id" : ObjectId("5a39c32aff6583393c37d98d"), "uploadDate" : ISODate("2017-12-20T01:56:06Z"), "A" : "1" }
{ "_id" : ObjectId("5a39c32aff6583393c37d98c"), "uploadDate" : ISODate("2017-12-20T01:56:09Z"), "A" : "1" }
{ "_id" : ObjectId("5a39c32aff6583393c37d98d"), "uploadDate" : ISODate("2017-12-20T01:56:10Z"), "A" : "1" }
{ "_id" : ObjectId("5a39c32aff6583393c37d98d"), "uploadDate" : ISODate("2017-12-20T01:56:11Z"), "A" : "1" }
{ "_id" : ObjectId("5a39c32aff6583393c37d98d"), "uploadDate" : ISODate("2017-12-20T01:56:12Z"), "A" : "1" }
按时间间隔5秒提取
结果如下：{ "_id" : ObjectId("5a39c32aff6583393c37d981"), "uploadDate" : ISODate("2017-12-20T01:55:54Z"), "A" : "1" }
{ "_id" : ObjectId("5a39c32aff6583393c37d988"), "uploadDate" : ISODate("2017-12-20T01:56:01Z"), "A" : "1" }
{ "_id" : ObjectId("5a39c32aff6583393c37d98d"), "uploadDate" : ISODate("2017-12-20T01:56:06Z"), "A" : "1" }
{ "_id" : ObjectId("5a39c32aff6583393c37d98d"), "uploadDate" : ISODate("2017-12-20T01:56:12Z"), "A" : "1" }没找到合适的方法，不知道那位兄台有好办法，谢谢！
