如何从数组而不是 Object 中提取数据？

Question

How to correctly extract data from array instead of [Object]

apiClient

export interface apiRequest {
  locations: LocationOptions[];

}
interface FOLocations {
  locationId: number;
}

interface LocationResult {
  location: FOLocations[];
  cityName: string;
}

export const locationCheck = async (
  apiKey: string,
  payload: apiRequest
): Promise<LocationResult[]> => {
  let response = await axios.post<LocationResult[]>(
    `api...`,
    payload
  );
  return response.data;

runCode

  const locationPayload : apiRequest = {
      locations:[{ cityName: "London"},{cityName: "New York"},{cityName: "Paris"}],
    };
    const locationResponse = await locationCheck(apiKey,locationPayload);
    const locationResponseRes =  locationResponse;
    console.log(locationResponseRes);

I need to get to values locationResponseRes.cityName. Actual output:

[
  {
    location: { locationId: 1, address: [Object] },
    deliveryOptions: [ [Object] ]
  },
  {
    location: { locationId: 2,},
    cityName: [ [Object] ]
  }
]
{
  "location": {
    "locationId": 1,
    cityName: [ [Object] ]
  }
}

Expected output(that what i got in Postman)

[
    {
        "location": {
            "locationId": 1,
            "cityName: "London",
        }
    },
    {
        "location": {
            "locationId": 2,
            "cityName": "New York",
        },    
},
]

and how to get to locationResponseRes.cityName ?

Answer 1

There are several ways that are used to console nested objects.

The best way to do so, while preserving the pretty print, is to use

console.log(JSON.stringify(obj, null, 2))

where 2 is the number of spaces to use for indentation.

Another option is to use

const util = require('util')

console.log(util.inspect(myObject, {showHidden: false, depth: null}))

// alternative shortcut
console.log(util.inspect(myObject, false, null, true /* enable colors */))

or

require('util').inspect.defaultOptions.depth = null
console.log(obj)

but the problem is that the nested objects after level 2 are now flattened, and this might be a problem with complex objects.
