将 LinkedHashMap 添加到 JSON object 内部的数组时出现问题

Question

I have this LinkedHashMap {Label=BEER, ID=179039, URL=https://website.website.com/browse/178974/178973/179039, Children=[]}

I also have a JSONObject with a single ArrayList inside of it like this: {"Categories":[]}

I am trying to append this LinkedHashmap to the array inside of the JSONObject, something like this:

{"Categories":[{Label=BEER, ID=179039, URL=https://website.website.com/browse/178974/178973/179039, Children=[]}]}

However when i do, and i print to the console, this is the output {"Categories":[{"link":"","URL":"https:\/\/Website.Website.com\/browse\/178974\/178973\/179039","Children":[]}]}

As you can see, the URL has come out wrong, and I am unsure as to why. Here is my code:

LinkedHashMap<String,Object> jo=new  LinkedHashMap<String,Object>();
       jo.put("link", "");
       jo.put("URL", "https://Website.Website.com/browse/178974/178973/179039");
       jo.put("Children",new ArrayList<>());
       List<LinkedHashMap<String,Object>> categories = new ArrayList<LinkedHashMap<String,Object>>();
       categories.add(jo);
       JSONObject ja1 = new JSONObject();
       ja1.put("Categories",categories);
       System.out.println(ja1);``` 

Note, this happens when I also simply just add the LinkedHashmap to the JSONObject EG:

{"Categories":{"link":"","URL":"https:\/\/Website.Website.com\/browse\/178974\/178973\/179039","Children":[]}}

I am using import org.json.simple.JSONObject;

Does anyone know why it is coming out incorrectly?

Answer 1

Using your code with:

import org.json.simple.JSONObject;

I also have this string:

{"Categories":[{"link":"","URL":"https:\/\/Website.Website.com\/browse\/178974\/178973\/179039","Children":[]}]}

Using your code with

import org.json.JSONObject; 

I have the following result:

{"Categories":[{"link":"","Children":[],"URL":"https://Website.Website.com/browse/178974/178973/179039"}]}

But if you desired to keep using org.json.simple.JSONObject; you might look up this page: How to add a URL String in a JSON object
