sending a JSONArray containing only a string in retrofit

Question

so I am trying to make a server request and the expected body for this request looks like this: ["1"]

but if I send a string as "[\"1\"]", I am getting an error

looking at the body, it's clear that I have to send a JSONArray , I tried achieving this using the following code:

JSONArray array = new JSONArray();
array.put("1");

but my body on stetho is shown as :

{
    "values":["1"]
}

maybe I am using a wrong class or something !

EDIT:

This is my api call with

OkHttpClient okHttpClient = new OkHttpClient.Builder()
                    .addNetworkInterceptor(new StethoInterceptor())
                    .build();

RetrofitService retrofitService2 =new Retrofit.Builder()
                    .baseUrl("http://blynk-cloud.com/")
                    .client(okHttpClient)
                    .addConverterFactory(GsonConverterFactory.create())
                    .build()
                    .create(RetrofitService.class);

retrofitService2.closeDoor("3bf11f14e6094dd5a8f31f6d6fac8f3d",
                    "[\"1\"]")
                    .enqueue(new Callback<String>() {
                        @Override
                        public void onResponse(Call<String> call, Response<String> response) {
                           {

                            }

                        }

                        @Override
                        public void onFailure(Call<String> call, Throwable t) {

                        }
                    });

closeDoor method:

@PUT("/{id}/update/D12")
    Call<String> closeDoor(@Path("id") String id, @Body String code);

my stetho response :

`["1"]` is not a properly formatted JSON string. If that is what you have to send, you are not going to be able to get it from any of the Android JSON classes; you'll need to just construct the string yourself and send it. — Scott Kronheim, Dec 21 '17 at 13:38
i was sending ["1"] as a string using "[\"1\"]" but it was still giving me the same issue — Abhishek Tiwari, Dec 21 '17 at 13:40
Can you update your post to include the code you are using to create the HTTP request and send it? Are you using the native HttpURLConnection class, or a HTTP library? — Scott Kronheim, Dec 21 '17 at 13:42
using retrofit here i am getting server error code 500 and everything seems to be fine except for maybe the body, are you sure this is the way? — Abhishek Tiwari, Dec 21 '17 at 13:51
Post your `RetrofitService` interface, at least the `closeDoor` method. There might be some clues there. — Leo Aso, Dec 21 '17 at 13:56

If you want to send request JSON like this ["1"]

Change to :

    JsonArray array = new JsonArray();
    array.add(new JsonPrimitive("1"));
    //output ["1"]

Instead of:

    JSONArray array = new JSONArray();
    array.put("1");

The reason you are getting a 500 error is that you are sending the response as text\plain as supposed to application\json which the server is expecting.

As suggested here, to send a raw JSON you need to use a RequestBody and pass it instead of String

RequestBody body = new RequestBody.create(MediaType.parse("application/json"),"[\"1\"]");

retrofitService2.closeDoor("3bf11f14e6094dd5a8f31f6d6fac8f3d",body).enqueue(...)

And change your retrofit method to

@PUT("/{id}/update/D12")
Call<String> closeDoor(@Path("id") String id, @Body RequestBody body);
