如何使用retrofit getting response作为对象将post数据json发送到api

public interface ApiService {
    @POST("api/endpoint")
    Call<ResponseBody> sendData(@Body RequestBody requestBody);
}

Retrofit retrofit = new Retrofit.Builder()
        .baseUrl("https://api.example.com/")
        .addConverterFactory(GsonConverterFactory.create())
        .build();

ApiService apiService = retrofit.create(ApiService.class);

DataObject dataObject = new DataObject("value1", "value2");
Gson gson = new Gson();
String json = gson.toJson(dataObject);
RequestBody requestBody = RequestBody.create(MediaType.parse("application/json"), json);

Call<ResponseBody> call = apiService.sendData(requestBody);

call.enqueue(new Callback<ResponseBody>() {
    @Override
    public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
        if (response.isSuccessful()) {
            // 处理成功响应
        } else {
            // 处理错误响应
        }
    }

    @Override
    public void onFailure(Call<ResponseBody> call, Throwable t) {
        // 处理请求失败
    }
});
