NodeJS API Request - parsed JSON Data

Question

I have this request which provides me JSON syntax

request( url, function (error, response) {
    console.log(JSON.parse(response.body))

This generates the following within the console:

{
  query: 'Manchester Holiday Inn',
  moresuggestions: 2,
  suggestions: [
    { group: 'CITY_GROUP', entities: [] },
    { group: 'HOTEL_GROUP', entities: [Array] },
    { group: 'LANDMARK_GROUP', entities: [] },
    { group: 'TRANSPORT_GROUP', entities: [Array] }
  ]
}

within the HOTEL GROUP syntax there is some additional information:

{
   "query":"Manchester Holiday Inn",
   "moresuggestions":0,
   "suggestions":[
      {},
      {
         "group":"HOTEL_GROUP",
         "entities":[
            {
               "geoId":"16071381",
               "destinationId":"4234234",
               "type":"HOTEL",
               "caption":"Manchester Holiday Inn Hotel",
               "name":"Manchester Holiday Inn Hotel"
            }
         ]
      },

I want to extract the destination ID and Hotel Name

     request( url, function (error, response) {
          const data = JSON.parse(response.body)
          hotelName = data['suggestions[1].entities[0].name'],
          hotelID = data["suggestions[1].entities[0].destinationId"]
          
          console.log(hotelName)
          console.log(hotelID)

But the output from the console shows that hotelName and hotelID are undefined. Not sure what I am doing wrong.

          undefined
          undefined

Answer 1

您可以像这样访问它

data["suggestions"][1]["entities"][0][name]

Answer 2

The syntax you're using to access the properties is wrong – you'll need

const hotelName = data.suggestions[1].entities[0].name
const hotelID = data.suggestions[1].entities[0].destinationId

instead.

You can also use object destructuring, like so:

const {name: hotelName, destinationId: hotelID} = data.suggestions[1].entities[0];
