Instead of Unirest, I'm using okhttp because there are responses where I only need the header so I don't need to download it using its ResponseBody.string() method.

I am however having a hard time building my requests for POSTs with a RequestBody. In Unirest, you only need to use thefieldmethod to add to the itsRequestBody`:

Unirest.post(baseUrl + "/api/user")

                .header("Authorization", token)

                .field("id", id)

                .field("property", property)

                .asJson();

But in OkHttp, if I want to add a RequestBody I have to do this (in most cases where I don't really have a json lying around):

OkHttpClient httpClient = new OkHttpClient();

Map<String, Object> payload = new HashMap<>();

payload.put("user_id", userId);

payload.put("client_id", clientId); 

payload.put("type", status.getStatus());

payload.put("description", ""); 

payload.put("duration", 0); 



String requestBody = new ObjectMapper().writeValueAsString(payload);



Call call = httpClient.newCall(

        new Request.Builder()



                .url(url) 

                .header("Authorization", tempToken)

                .post(RequestBody.create(MediaType.get("application/json"), requestBody))

                .build()

);

I'm using a Map to create a json string because this is the easiest way for me to create a json.

Does OkHttp have something easier similar to Unirest's field method for creating a RequestBody?

I found okhttp has FormBody which has a Builder:

Call call = httpClient.newCall(

        new Request.Builder()

                .url(url)

                .header("Authorization", tempToken)

                .post(new FormBody.Builder()

                        // TODO user getId()

                        .add("id","")

                        .add("custom_fields", field)

                        .build())

                .build()

);

OkHttp doesn't have asJson. You can add a custom interceptor or implement a separate JSONObject.

Build JSON using JSONObject:

JSONObject jsonObject = new JSONObject();

try {

    jsonObject.put("username", "yourEmail@com");

    jsonObject.put("password", "yourPassword");

    jsonObject.put("anyKey", "anyValue");

} catch (JSONException e) {

    e.printStackTrace();

}

Then call OkHttp like this:

public static final MediaType JSON = MediaType.parse("application/json; charset=utf-8");



OkHttpClient client = new OkHttpClient();



String post(String url, String json) throws IOException {

  RequestBody body = RequestBody.create(JSON, json);

  Request request = new Request.Builder()

      .url(url)

      .post(body)

      .build();



  Response response = client.newCall(request).execute();

  return response.body().string();

}
