我在数据库中有以下数据
db.report.insert({ "_id" : ObjectId("54d70"), "server" : { "timestamp" : "Thu Feb 12 07:14:19 2015", "person" : "lali", "candidate" : [ { "isno" : "63", "id" : "4c:64:33:e9" } ], "id" :"24" } })
db.report.insert({ "_id" : ObjectId("5471"), "server" : { "timestamp" : "Thu Feb 12 07:14:39 2015", "person" : "lali", "candidate" : [ { "isno" : "4", "id" : "4c:64:33:e9" } ], "id" : "24" } })
db.report.insert({ "_id" : ObjectId("5472"), "server" : { "timestamp" : "Thu Feb 12 07:14:09 2015", "person" : "lali", "candidate" : [ { "isno" : "6", "id" : "4c:64:33:e9" } ], "id" : "24" } })
通过输入值timestamp ''Thu Feb 12 07:14:19 2015' ,id 4c:64:33:e9 and id :24
我需要提取iso密钥值63 ,4 and 6
