Retrieving information from a JSON object that includes arrays

I've been researching how to extract data from the response body of a server, but I haven't had much luck finding a solution that works for my https request returning a JSON object.

//Initiate the request:
request({

  //Specify the request method:
  method: 'POST',
  //Include headers:
  headers: {
    'Content-Type': 'application/json',
    'Authorization': "Bearer "+ token,
    'X-Originating-Ip': ipAddress
  },
  //Provide the URL:
  url: 'URL',
  //Include the request body:
  body: { 'Body here'},
  }, function(error, response, body){

    //Display the response body:
    for(var i=0; body.data.listings.length; i++){
      console.log(data.listings[i].listingType);
    }
    console.log(response.statusCode);
  });

Due to security concerns, I'm unable to share the specific response body, but it contains multiple arrays in JSON format.

Answer №1

It may be beneficial to try

console.log(body.data.listing[i].listingType)

Here is another method that could help resolve the issue:

body.data.listings.forEach(function(element,index){
   //perform a task
}

Answer №2

The issue lies within the for loop

for(var i=0; body.data.listings.length; i++){
  console.log(data.listings[i].listingType);
}

Firstly, the termination condition of the loop is body.data.listings.length, which will always return the length of the listings array and is always truthy for a non-empty array. You should modify the loop declaration to

for(var i=0; i<body.data.listings.length; i++){

This way, it will accurately iterate over all items in the array. Secondly, as James pointed out, you should use

body.data.listings[i].listingType
instead of data.listings[i].listingType within the loop.
