Question

这些数据是我得到的

ref

我可以使用此代码获得s值，并返回“ok”。

var SelectOptionItemSchema = mongoose.Schema({ "name": { "type": "String", "required": true, "unique": true } })

var SelectOptionItem = mongoose.model('SelectOptionItem', SelectOptionItemSchema);

var firstOptionItem = new SelectOptionItem({name: "1"}); //5a18cfe79a61fd183530d467
var secondOptionItem = new SelectOptionItem({name: "2"}); //5a18d0089a61fd183530d469

let modelFields = {
    "name": { "type": "String", "required": true, "unique": true },
    "description": { "type": "String" },
    "options": [{type: "ObjectId", ref: "SelectOptionItem"}],
    "company_id": { "type": "ObjectId", "ref": "Company", "required": true },
    "deleted": { "type": "Boolean", "required": true },
    "createdAt": { "type": "Number" },
    "updatedAt": { "type": "Number" }
};

var SelectOptionSchema = mongoose.Schema(modelFields)

var SelectOption = mongoose.model('SelectOption', SelectOptionSchema);

var data = { name: 'aa', description: 'aa', options: [ "5a18cfe79a61fd183530d467", "5a18d0089a61fd183530d469" ], company_id: '59b2cd9a072e4f28b839aaa0', deleted: false, createdAt: 1511569192524 }


var newSelectOption = new SelectOption(data)

SelectOption.find({}, function(err, response) { 
    console.log(response)
}).populate('options')

但是我得到了其他值的错误，如何从这个json获得t，r，s，v作为数组或字符串列表？

{
  "s": "ok",
  "t": [
    1509469200,
    1509469500,
    1509469800,
    1509470100,
    1509470400,
    1509470700,
    1509471000
  ],
  "r": [
    6040100,
    5955000,
    5955000,
    5999600,
    5999400,
    5999000,
    5960100
  ],
  "v": [
    3.06575198,
    7.92733913,
    6.04823174,
    0.87041449,
    0.27879491,
    0.31525724,
    0.08880846
  ]
}

Answer 1

创建一个类

Public Class JSON_result
    Public Property s As String
    Public Property t As Integer()
    Public Property r As Integer()
    Public Property v As Double()
End Class

然后将json反序列化为该类的对象。

Dim obj = JsonConvert.DeserializeObject(Of JSON_result)(response_jsonString)

现在您可以访问属性，

obj.s 和数组元素 obj.t(0) obj.r(0) obj.v(0)

Json反序列化具有多个值
