안드로이드 코드는 retrofit부분만 업로드함

public class ApiClient {
    private static final String BASE_URL = "서버주소";
    private static Retrofit retrofit;

    public static Retrofit getApiClient()
    {
        Gson gson = new GsonBuilder()
                .setLenient()
                .create();

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

        return retrofit;
    }

}

public interface RetrofitInterface {
    //api를 관리해주는 인터페이스
    @Multipart
    @POST("upload_chat.php")
    Call<String> request(@Part MultipartBody.Part file);

}

  private void uploadChat(){
        RequestBody requestFile = RequestBody.create(MediaType.parse("multipart/form-data"), imageFile);
        MultipartBody.Part body = MultipartBody.Part.createFormData("uploaded_file", imageFileName, requestFile);
        RetrofitInterface retrofitInterface=ApiClient.getApiClient().create(RetrofitInterface.class);
        Call<String> call=retrofitInterface.request(body);
        call.enqueue(new Callback<String>() {
            @Override
            public void onResponse(Call<String> call, Response<String> response) {
                Log.e("uploadChat()", "성공 : ");
            }

            @Override
            public void onFailure(Call<String> call, Throwable t) {
                Log.e("uploadChat()", "에러 : " + t.getMessage());
