How to send multipart/form data with array from Java?

Question

When I use Postman, I send a request like "form-data", and it works.

I know how to make a request, but I do not know how to assemble the body of such a request.

enter image description here

The resource to which I should send the post request expects this format:

array 
(
   "data" =>  array
        (
            0 =>  array 
            (
                "external_id" => 123, 
                "count"       => 1,
                "price"       => 1000,
            ),
        1 =>  array 
            (
                "external_id" => 345,
                "count"       => 2,
                "price"       => 2000,
            ),
        2 =>  array 
            (
                "external_id" => 456,
                "count"       => 3,
                "price"       => 3000,
            ),
    ),

)

Thanks for any help.

Answer 1

have you tried with this in raw format?

I think when it comes to JSON structures a PHP array is taken like a JSON object. So what you would need to do here is to put all your JSON inside a data field of content-type application/json as shown in this screenshot and it should work. Let me know how it goes.
