Mongoimport 特定格式

编程问答 2022-05-01

问题描述

是否可以从 .json 文件导入这种格式的 mongo db？

{
  "user1": {
    "username": "u1","password": "passw1","id": 1
  },"user2": {
    "username": "u2","password": "p2","id": 2
  },"user3": {
    "username": "u3","password": "pw3","id": 3
  }
}

我尝试了命令 mongoimport --db mydatabase --collection users --file users.json --drop 并且该集合如下所示：

{ 
  "_id" : ObjectId("60a577984fc88b06cd3a6943"),"user1" : { "username" : "u1","password" : "password1","id" : 1 },"user2" : { "username" : "u2","password" : "password2","id" : 2 },"user3" : { "username" : "u3","password" : "password3","id" : 3 } 
}

我需要它看起来像什么：

{
  {"_id" : ObjectId("60a577984fc88b06cd3a6943"),"username" : "u1","password" : "passw1",{"_id" : ObjectId("60a577984fc88b06cd3a6943"),"username" : "u2","password" : "p2","username" : "u3","password" : "pw3","id" : 3 } 
}
