how to pass raw json data to retrofit 2.0

Question

Hi i am new to retrofit and facing problem to post json data for calling api's. I tried with many solutions but not getting the answer.

This is my code

                      Map<String,String> data=new HashMap<>();
                data.put("email",email);
                data.put("feedback",feedback);
                RequestBody body = RequestBody.create(okhttp3.MediaType.parse("application/json; charset=utf-8"), (new JSONObject(data)).toString());
                Call<Feedback> call = apiInterface.feedbackResponse(accessToken,tokenType,client,expiry,uid,body);
                call.enqueue(new Callback<Feedback>() {
                    @Override
                    public void onResponse(Call<Feedback> call, Response<Feedback> response) {
                        Log.e("Response",String.valueOf(response.code()));
                        Message message=response.body().getMessage();
                        String messageBody=message.toString();
                        String status=response.body().getStatus();
                        Toast.makeText(getApplicationContext(),status+" : "+messageBody,Toast.LENGTH_LONG).show();
                    }

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

                    }
                });

and My interface is

      @POST("feedbacks")
public Call<Feedback> feedbackResponse(@Header(ApiConstant.ACCESS_TOKEN) String accessToken, @Header(ApiConstant.TOKEN_TYPE) String tokenType,
                                       @Header(ApiConstant.CLIENT) String client, @Header(ApiConstant.EXPIRY) String expiry,
                                       @Header(ApiConstant.UID) String uid, @Body RequestBody feedback);

Using headers like this is not giving problem as i am using it for every api. So dont consider headers is the problem.

My Response is

  public class Feedback {
private Message message;

private String status;

private Data data;

public Message getMessage ()
{
    return message;
}

public void setMessage (Message message)
{
    this.message = message;
}

public String getStatus ()
{
    return status;
}

public void setStatus (String status)
{
    this.status = status;
}

public Data getData ()
{
    return data;
}

public void setData (Data data)
{
    this.data = data;
}

@Override
public String toString()
{
    return "ClassPojo [message = "+message+", status = "+status+", data = "+data+"]";
}

}

Plese suggest me the right way.

Change signature to

@POST("feedbacks")
    public Call<Feedback> feedbackResponse(@Header(ApiConstant.ACCESS_TOKEN) String accessToken, @Header(ApiConstant.TOKEN_TYPE) String tokenType,
                                           @Header(ApiConstant.CLIENT) String client, @Header(ApiConstant.EXPIRY) String expiry,
                                           @Header(ApiConstant.UID) String uid, @Body Map<String,Object> feedback);

and calling to

Map<String,Object> data=new HashMap<>();
                data.put("email",email);
                data.put("feedback",feedback);
apiInterface.feedbackResponse(accessToken,tokenType,client,expiry,uid,data);

or change @Body data type to JsonObject and try

JsonObject data = new JsonObject();
    data.addProperty("email",email);
    data.add("feedback",new Gson().toJsonTree(feedback));
apiInterface.feedbackResponse(accessToken,tokenType,client,expiry,uid,data);

or you can also try @Body FeedbackRequestData data . there are multiple way to do it.

apiInterface must initialize with gson parser. And if header is required in every request then use okHttp interceptor.

Make sure your Feedback class is generated by http://www.jsonschema2pojo.org/ while choosing JSON and GSON
