Having trouble with transferring JSON data as a string from POSTMAN to a node server

My JSON data structure is as follows:

const json = {
   "name": "Peter",
   "age": 21
}

After calling JSON.stringify(json), the result is:

'{"name":"Peter","age":21}'

I am currently using POSTMAN to send data from the UI to my server with the following details:

POST
http:localhost:8888/user
Body -> JSON

{
  "user": { 
     "details": '{"name":"Peter","age":21}',
     "foo": "bar"
   }
}

The problem arises when sending over the data as I receive the error on the server:

SyntaxError: Unexpected token } in JSON at position 114

Any suggestions or solutions to this issue?

Answer №1

It is important to note that JSON does not support the use of single quotes. The data you are attempting to send is considered invalid due to this limitation. To rectify this, you should instead utilize double quotes and properly escape any internal quotes for the JSON key/value pairs:

{
  "user": { 
     "details": "{\"name\":\"Peter\",\"age\":21}",
     "foo": "bar"
   }
}
