Extract information from a string to retrieve the array specifications

After making a request to the server, I received the following response:

{
  "statusCode": 200,
  "body": "{\"Errors\":\"\",\"Message\":\"\",\"Output\":\"\",\"TokenID\":\"F106457749C\",\"OrgID\":0,\"OutputObject\":{\"Details\":{\"CatalogDetail\":[{\"CatalogID\":74,\"CategoryID\":22,\"ShortCatalogName\":\"Email Forwarding\",\"CatalogName\":\"Email Forwarding\",\"Description\":\"Use this catalog for email forwarding \",\"IsVendor\":false,\"IsPackage\":false,\"AncestorParent_CategoryID\":58,\"IsEntitled\":0,\"CategoryName\":\"Email\",\"ServiceCatalogBGColor\":\"\"}],\"BaseUrl\":\"https://serviceimg-attachments\"}}}",
  "headers": {
    "cache-control": "private",
    "content-type": "application/octet-stream",
    "server": "Microsoft-IIS/8.5",
    "set-cookie": [
      "ASP.NET_SessionId=m0jbtyi12mzefkkyh3xd4i0m; path=/; HttpOnly",
      ".ASPXAUTH=41C6BC3E87DBF106457749C; path=/"
    ],
    "x-aspnet-version": "4.0.30319",
    "x-powered-by": "ASP.NET",
    "date": "Mon, 15 Oct 2018 17:51:09 GMT",
    "connection": "close",
    "content-length": "779"
  }
}

I am attempting to parse the string response.body in order to retrieve the array 

response.body.OutputObject.Details.CatalogDetail
. However, I am encountering an issue where Details is undefined. Could someone provide guidance on how to access the CatalogDetail Array?

Thank you, Arul

Answer №1

Here is a suggestion for you:

You can parse the JSON string like this:
var jsonObj = JSON.parse("your json string");

Answer №2

In order to access the object, it is necessary to first parse the JSON data. The JSON.parse method can be used to parse the JSON string.

var jsonData = '{"success":true, "quantity":10}';
var obj = JSON.parse(jsonData);

Answer №3

This is the method I've been using and it's effective. Instead of trying to parse the entire object at once, extract the body object first.

var body = JSON.parse(data["response"])

After that, you can access the specific details like this.

JSON.parse(data["response"]).OutputObject.Details.CatalogDetail

Answer №4

To properly read the content, it is necessary to interpret the body as JSON data. Most likely, the framework being utilized offers a method similar to response.json(), but alternatively, you can employ JSON.parse.

response = {
  "statusCode": 200,
  "body": "{\"Errors\":\"\",\"Message\":\"\",\"Output\":\"\",\"TokenID\":\"F106457749C\",\"OrgID\":0,\"OutputObject\":{\"Details\":{\"CatalogDetail\":[{\"CatalogID\":74,\"CategoryID\":22,\"ShortCatalogName\":\"Email Forwarding\",\"CatalogName\":\"Email Forwarding\",\"Description\":\"Use this catalog for email forwarding \",\"IsVendor\":false,\"IsPackage\":false,\"AncestorParent_CategoryID\":58,\"IsEntitled\":0,\"CategoryName\":\"Email\",\"ServiceCatalogBGColor\":\"\"}],\"BaseUrl\":\"https://serviceimg-attachments\"}}}",
  "headers": {
    "cache-control": "private",
    "content-type": "application/octet-stream",
    "server": "Microsoft-IIS/8.5",
    "set-cookie": [
      "ASP.NET_SessionId=m0jbtyi12mzefkkyh3xd4i0m; path=/; HttpOnly",
      ".ASPXAUTH=41C6BC3E87DBF106457749C; path=/"
    ],
    "x-aspnet-version": "4.0.30319",
    "x-powered-by": "ASP.NET",
    "date": "Mon, 15 Oct 2018 17:51:09 GMT",
    "connection": "close",
    "content-length": "779"
  }
}
body = JSON.parse(response.body)
body.OutputObject.Details.CatalogDetail

Answer №5

Use JSON.parse(data.body) to convert the string into JSON format and perform any desired operations,

Here is a code snippet for reference:

var data = {
  "statusCode": 200,
  "body": "{\"Errors\":\"\",\"Message\":\"\",\"Output\":\"\",\"TokenID\":\"F106457749C\",\"OrgID\":0,\"OutputObject\":{\"Details\":{\"CatalogDetail\":[{\"CatalogID\":74,\"CategoryID\":22,\"ShortCatalogName\":\"Email Forwarding\",\"CatalogName\":\"Email Forwarding\",\"Description\":\"Use this catalog for email forwarding \",\"IsVendor\":false,\"IsPackage\":false,\"AncestorParent_CategoryID\":58,\"IsEntitled\":0,\"CategoryName\":\"Email\",\"ServiceCatalogBGColor\":\"\"}],\"BaseUrl\":\"https://serviceimg-attachments\"}}}",
  "headers": {

    "connection": "close",
    "content-length": "779"
  }
};
var output = JSON.parse(data.body);
console.log(output.OutputObject.Details.CatalogDetail);

Answer №6

To access specific properties, use JSON.parse and refer to the documentation on Property Accessors.

  var obj = {
      "statusCode": 200,
      "body": "{\"Errors\":\"\",\"Message\":\"\",\"Output\":\"\",\"TokenID\":\"F106457749C\",\"OrgID\":0,\"OutputObject\":{\"Details\":{\"CatalogDetail\":[{\"CatalogID\":74,\"CategoryID\":22,\"ShortCatalogName\":\"Email Forwarding\",\"CatalogName\":\"Email Forwarding\",\"Description\":\"Use this catalog for email forwarding \",\"IsVendor\":false,\"IsPackage\":false,\"AncestorParent_CategoryID\":58,\"IsEntitled\":0,\"CategoryName\":\"Email\",\"ServiceCatalogBGColor\":\"\"}],\"BaseUrl\":\"https://serviceimg-attachments\"}}}",
      "headers": {
        "cache-control": "private",
        "content-type": "application/octet-stream",
        "server": "Microsoft-IIS/8.5",
        "set-cookie": [
          "ASP.NET_SessionId=m0jbtyi12mzefkkyh3xd4i0m; path=/; HttpOnly",
          ".ASPXAUTH=41C6BC3E87DBF106457749C; path=/"
        ],
        "x-aspnet-version": "4.0.30319",
        "x-powered-by": "ASP.NET",
        "date": "Mon, 15 Oct 2018 17:51:09 GMT",
        "connection": "close",
        "content-length": "779"
      }
    }

    var formated = JSON.parse(obj.body);

    var CatalogDetail = formated.OutputObject.Details.CatalogDetail[0];
    console.log(CatalogDetail);

Answer №7

the reason for this issue is that the body's value is in string format. If you want to access it as a JSON format, you will need to parse it first. Below is a code snippet for more clarification:

var response = {
  "statusCode": 200,
  "body": "{\"Errors\":\"\",\"Message\":\"\",\"Output\":\"\",\"TokenID\":\"F106457749C\",\"OrgID\":0,\"OutputObject\":{\"Details\":{\"CatalogDetail\":[{\"CatalogID\":74,\"CategoryID\":22,\"ShortCatalogName\":\"Email Forwarding\",\"CatalogName\":\"Email Forwarding\",\"Description\":\"Use this catalog for email forwarding \",\"IsVendor\":false,\"IsPackage\":false,\"AncestorParent_CategoryID\":58,\"IsEntitled\":0,\"CategoryName\":\"Email\",\"ServiceCatalogBGColor\":\"\"},{\"CatalogID\":75,\"CategoryID\":22,\"ShortCatalogName\":\"Email Forwarding2\",\"CatalogName\":\"Email Forwarding2\",\"Description\":\"Use this catalog for email forwarding \",\"IsVendor\":false,\"IsPackage\":false,\"AncestorParent_CategoryID\":58,\"IsEntitled\":0,\"CategoryName\":\"Email\",\"ServiceCatalogBGColor\":\"\"}],\"BaseUrl\":\"https://serviceimg-attachments\"}}}",
  "headers": {
    "cache-control": "private",
    "content-type": "application/octet-stream",
    "server": "Microsoft-IIS/8.5",
    "set-cookie": [
      "ASP.NET_SessionId=m0jbtyi12mzefkkyh3xd4i0m; path=/; HttpOnly",
      ".ASPXAUTH=41C6BC3E87DBF106457749C; path=/"
    ],
    "x-aspnet-version": "4.0.30319",
    "x-powered-by": "ASP.NET",
    "date": "Mon, 15 Oct 2018 17:51:09 GMT",
    "connection": "close",
    "content-length": "779"
  }
}
var body = JSON.parse(response.body)
var Catalogs = body.OutputObject.Details.CatalogDetail;
for(var i=0;i<Catalogs.length;i++){
    console.log("CatalogID : " + Catalogs[i].CatalogID)
    console.log("ShortCatalogName : " + Catalogs[i].ShortCatalogName);
}
$.each(Catalogs, function( index, value ) {
  console.log(  "CatalogID : " + value.CatalogID );  
  console.log(  "ShortCatalogName : " + value.ShortCatalogName );
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
you can utilize either a simple for loop or $.each loop to iterate through the array
