[javascript] How to send data in request body with a GET when using jQuery $.ajax()

The service API I am consuming has a given GET method that requires the data be sent in the body of the request.

The data required in the body is a list of id's separated by hypen and could potentially be very large and thus it must be sent in the body otherwise it will likely foobar somewhere in the browsers/proxies/webservers etc chain. Note I don't have control over the service or API so please don't make suggestions to change it.

I am using the following jQuery code however observing the request/response in fiddler I can see that the "data" I am sending is ALWAYS converted and appended to the query string despite me setting the "processData" option to false...

$.ajax({
   url: "htttp://api.com/entity/list($body)",
   type: "GET",
   data: "id1-id2-id3",
   contentType: "text/plain",
   dataType: "json",
   processData: false, // avoid the data being parsed to query string params
   success: onSuccess,
   error: onError
});

Anyone know how I can force the "data" value to be sent in the body of the request? Any assistance is appreciated, thanks in advance.

Just in case somebody ist still coming along this question:

There is a body query object in any request. You do not need to parse it yourself.

E.g. if you want to send an accessToken from a client with GET, you could do it like this:

const request = require('superagent');_x000D_
_x000D_
request.get(`http://localhost:3000/download?accessToken=${accessToken}`).end((err, res) => {_x000D_
  if (err) throw new Error(err);_x000D_
  console.log(res);_x000D_
});

The server request object then looks like {request: { ... query: { accessToken: abcfed } ... } }

we all know generally that for sending the data according to the http standards we generally use POST request. But if you really want to use Get for sending the data in your scenario I would suggest you to use the query-string or query-parameters.

1.GET use of Query string as. {{url}}admin/recordings/some_id

here the some_id is mendatory parameter to send and can be used and req.params.some_id at server side.

2.GET use of query string as{{url}}admin/recordings?durationExact=34&isFavourite=true

here the durationExact ,isFavourite is optional strings to send and can be used and req.query.durationExact and req.query.isFavourite at server side.

3.GET Sending arrays {{url}}admin/recordings/sessions/?os["Windows","Linux","Macintosh"]

and you can access those array values at server side like this

let osValues = JSON.parse(req.query.os);
        if(osValues.length > 0)
        {
            for (let i=0; i<osValues.length; i++)
            {
                console.log(osValues[i])
                //do whatever you want to do here
            }
        }

You can send your data like the "POST" request through the "HEADERS".

Something like this:

$.ajax({
   url: "htttp://api.com/entity/list($body)",
   type: "GET",
   headers: ['id1':1, 'id2':2, 'id3':3],
   data: "",
   contentType: "text/plain",
   dataType: "json",
   success: onSuccess,
   error: onError
});
