Retrofit post request structure

Question

I need to make a POST-request in android. Before I tried it in Postman and it works fine.

But in Android (I'm using Retrofit2) it don't want to connect with server.

My ApiService:

@POST("home/info/")
Call<ResponseData> getJson(@Body Post post);

My RetrofitClient:

Retrofit.Builder()
            .baseUrl(http://api.beauty.dikidi.ru/)
            .addConverterFactory(GsonConverterFactory.create())
            .build();

My Post body class

private String city_id;

public String getCity_id() {
    return city_id;
}

public void setCity_id(String city_id) {
    this.city_id = city_id;
}

I tried different solutions: @Query, @Field. I tried to play with URL like here. My breakepoint in OnResponse is not reached. Please, help me to set up connection!

It shows that connection is OK but parametres are passing incorrectly.

The problem with passing parametres was resolved. Now code inside in Retrofit is not called.

Call snippet:

    ApiService apiService = RetrofitClient.getApiService();
    Call<ResponseData> call = apiService.getJson(CITY_ID);
    call.enqueue(new Callback<ResponseData>() {
        @Override
        public void onResponse(Call<ResponseData> call, Response<ResponseData> response) {
            int status = response.code();
            String count = response.body().getData().getBlock().getShare().getCount();
            Log.d("myLog", count);
            getViewState().showShare(count);
        }

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

        }
    });

@ADM in presenter. Should I to update my post with call point? — , Mar 14 '18 at 09:23
Please use Intercepter and debug how your requests are passing... — Shalu T D, Mar 14 '18 at 09:24
@ShaluTD Intercepter? Do you mean breakpoint? If yes, I use it. — , Mar 14 '18 at 09:26
No. I am saying the https://www.learn2crack.com/2016/06/retrofit-okhttp-logging-interceptor.html. why you reduce my point? — Shalu T D, Mar 14 '18 at 09:29
You can change post method of your parameter - check it -https://stackoverflow.com/questions/21398598/how-to-post-raw-whole-json-in-the-body-of-a-retrofit-request — Adil, Mar 14 '18 at 09:31

Try this

@POST("home/info/{city_id}")
Call<ResponseData> getData(@Path("city_id") int cityId);

It is incorrect URL for this API. It would be too easy – Mar 14 '18 at 10:29

Here is some steps for call post request in retrofit.

Make http request with retrofit.

public IWebInterface serviceCallApi() {
 HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
        logging.setLevel(HttpLoggingInterceptor.Level.BODY);
        OkHttpClient.Builder builder = new OkHttpClient.Builder()
                .connectTimeout(Constants.Web.CONNECTION_TIMEOUT, TimeUnit.SECONDS)
                .writeTimeout(Constants.Web.CONNECTION_TIMEOUT, TimeUnit.SECONDS)
                .readTimeout(Constants.Web.CONNECTION_TIMEOUT, TimeUnit.SECONDS);
        builder.addInterceptor(logging);
        OkHttpClient client = builder.build();
        Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(add_your_base_url)
                .client(client)
                .addConverterFactory(JacksonConverterFactory.create())
                .build();
        return retrofit.create(IWebInterface .class);
}

Create interface which will append request parameter

public interface IWebInterface {
@POST("home/info/")
@FormUrlEncoded
Call<ResponseData> getJson(@Field("city_id") String title);

}

Now you already created model. fill this model as a body to your retrofit call

 public boolean callApi(){
 boolean isSuccess = false;
 Call<ResponseData> call = serviceCallApi.getJson(pass_your_city);
        try {

            Response<ResponseData> response= call.execute();
            if (response.code() == 200) {
                ResponseData responseParser = response.body();
                if (responseParser != null) {
                    isSuccess = true;                       
                }
            }  
        } catch (IOException e) {
            Log.e("Exception", e.getMessage());
        }
}
 return isSuccess;

}

your model :

public class Post {

    @SerializedName("city_id")
    @Expose
    private String title;           
    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }


}

here is the steps i did in my project for call POST retrofit. Hope it will help you!!

I tried like this but there is no profit. I found out that the connection is OK, but parametres are passing incorrectly. Is there any problem in annotations or URL? — , Mar 14 '18 at 10:04
I don't know how is request url looks like. In my task I need to make a POST-request with "city_id" parameter. In Postman it works fine, but in Retrofit it isnt — , Mar 14 '18 at 10:17
Hmm.. It works (so what was in my base code), but code inside retrofit is not called. Now i will update my post — , Mar 14 '18 at 10:47
you have to check if have done some minor mistake, if post helpfull than you can accept or make upvote @EAMax thanks!! — Hemant Parmar, Mar 14 '18 at 11:55
