Retrofit posts empty data

I'm new to Retrofit. I simply add a row to my database with using retrofit but i used field parameters in my api interface like this.

Call<String> matchWith(@Field("fbid") String fbid, @Field("matchwith") String matchwith);

It is hard to write for big objects so i decided to use @Body annotation. But now its posting empty row/object in my mysql database. (With @Field annotation in api interface my code inserts the data correctly)

Here is my code

@POST("/insertuser.php")
Call<User> postUser(@Body User user);



Retrofit retrofit = new Retrofit.Builder()
            .baseUrl("http://myurl.com")
            .addConverterFactory(GsonConverterFactory.create())
            .build();

    Connect connect = retrofit.create(Connect.class);

    Call<User> call = connect.postUser(user);
    call.enqueue(new Callback<User>() {
        @Override
        public void onResponse(Call<User> call, Response<User> response) {

        }

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

        }
    });

In my object class i used @SerializedName and @Expose retrofit still inserts empty I have tried with just @SerilizedName and just with @Expose after that I used nothing but I got same result.

HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
        logging.setLevel(HttpLoggingInterceptor.Level.BODY);
        OkHttpClient.Builder httpClient=new OkHttpClient.Builder();
        httpClient.addInterceptor(logging);**


        if (retrofit == null) {
            retrofit = new Retrofit.Builder()
                    .baseUrl(BASE_URL)
                    .addConverterFactory(GsonConverterFactory.create())
                    .client(httpClient.build())
                    .build();
        }

Now you can see if you send the correct data and server responses correctly, otherwise search the problem in server

There is difference between @Field and @Body annotations. Your API might be accepting data as form-data only. That is why your data is considered as empty data when you send it through request body i.e. using @Body annotation.

You can change your web API to accept data as request body and then use as your are using.
