1 UVOD
Mrežni servis (web service) predstavlja način komunikacije između dva elektronska uređaja na
mreži. Ova komunikacija se obično vrši tako što klijent šalje zahtev pomoću mrežnog servisa serveru
i rezultujuća informacija se vraća klijentu u nekom obliku. Danas se koriste dva dominantna mrežna
servisa SOAP i REST (RESTful).
U ovom radu radićemo na Translate web servisu koji je baziran na RESTful servisu čija će
glavna funkcija biti prevod prosleđenih reci na jedan od selektovanih jezika. Prevod reči će biti
baziran na principu reč za reč i podržavaće više jezika koji korisnik može da koristi.
Web servis će imati nekoliko metoda koji komuniciraju sa bazom jezika od kojih će neke
omogućavati korisniku da trazi i dobije prevod tražene reči, a ostale omogućavati privilegovanom
korisniku (adminu) ubacivanje, izmenu ili brisanje iz baze podataka web servisa.
Uz diplomski poželjno je da se napravi sajt koji komunicira sa web servisom, sa odvojenom
zasebnom bazom za korisnike. Sajt treba da pokaže mogućnosti i funkcionalnost zasebnog web
servisa.

2 RADNO OKRUŽENJE
Prilikom izrade web servisa korišćen je Slim framework v.3.0. Pored toga, na
serverskoj strani podaci su skladišteni u MySQL bazu podataka koja je administrirana
alatima PhpMyAdmin, dok sajt translate je napisan u funkcionalnom PHP-u sa takođe MySQL
bazu podataka koja je takođe administrirana alatima PhpMyAdmin.
Web servis ne poseduje nikakav dizajn sem index strane u kojoj su opisanne funkcije
servisa. Dok sajt sluzi da pokaže funkcionalnost web servisa i sajt sadrži JavaScript sa JQuery
bibliotekom, CSS3 i HTML5. Sajt je responsive (prilagođava se veličini ekrana korisnika).
U toku razvoja aplikacije korišćena su sledeća razvojna okruženja:
• Notepad++
• PhpMyAdmin
• Advanced REST client

2.1 Slim Framework
Slim je mikro PHP framework koji omogućava brzo pisanje moćnih web aplikacija i API-
a. Sto nas dovodi do zaključka da slim framework sadrzi samo najvazniji set alata koji
omogućavaju veliku fleksibilnost u pravljenju web servisa.
Slim framework je napravljen 2013 godine kada su micro framework-ci doživeli veliki
uspeh i ostao je popularan do dana danas. „Micro“ zato što je sastavljen samo od neophodnih
stvari da se napravi web applikacija. Obični micro framework radi na principu primanja HTTP
zahteva, obradjivanje tog HTTP zahteva preko određenog kontrolera, i vraća HTTP odgovor.
Slim framework je otišao stepenicu više i ponudio još dodatne alate za manipulaciju HTTP
odgovora (HTTP keš, ažuriranje statusa, preusmerenje, itd.).
Medjutim, veliki broj programera su više upućeni u velike full-stack framework-e kao što
su Laravel ili Symfony. Ovi odlični framework-ci imaju veliku podršku i veliku grupu ljudi
koje rade na svakodnevnom razvijanju softvera. Za neke projekte full-stack framework-ci su
idealno rešenje jer imaju ogromne mogućnosti, dok zahtevaju dodatno podešavanje i dodatnu
logiku. Dok sa druge strane ako pravite web servis koji je zasnovan na REST-u, Slim
framework je idealno rešenje jer poseduje dosta manje podešavanja a pruža velike mogućnosti
u toj oblasti.

3 ORGANIZACIJA
Kao sto je navedeno diplomski se sastoji iz dva dela:
WEB SERVIS-a pisanog u Slim framework Lokalnom sajtu koji komunicira sa web servisom
3.1 Web SERVICE
Poseduje pet različitih metoda, koji manipulišu sa bazom podataka. Ne poseduje nikakv
GUI jer poenta web servisa je u obrađivanju poslatih informacija i dobijanja odgovora u odnosu
na poslati zahtev. Baza podataka sadrži sedam različitih jezika : Arapski, Nemački, Italijanski,
Portugalski, Ruski i Španski.

URLM E T O D A
PARAMETRI OPIS
v1/translate
POST
translateFrom, translateTo, words
Prevodi reči na jedan selektovan jezik, morate proslediti jezik od (translateFrom) i jezik na (translateTo) i reči (kao string parametar)
v1/translates
POST
translateFrom, words
Prevodi reči na sve jezike, morate proslediti jezik od (translateFrom) i reči (kao string parametar)
v1/insertTranslates
POST
english,arabic, german,italian, portuguese, russian, Spanish
Ubacuje podatke u bazu, ubacuje reči u sve jezike zato sto REST redi na principu reč za reč, tako da je portrebno proslediti po jednu reč za svaki jezik u bazi (english,arabic,german,italian, portuguese,russian,spanish)
v1/deleteTranslates
DELETE
word,languageBrise podatke iz baze, mora da se prosledi reč (word) I takođe jezik gde ta reč postoji (language)
v1/editTranslatesPUT
english,arabic, german,italian, portuguese, russian, Spanish
Edituje reči u bazi, edituje reći u svim jezicima zato sto REST radi na principu reč za reč, tako daj je potrebno proslediti reč za svaki jezik (english, arabic, german,italian,portuguese,russian,spanish), kao i id reči koju zelite da editujete.

3.2 Lokalni Sajt
Lokalni sajt koji prati funkcije web servisa i na najbolji način ih primenjuje. Sajt predstavlja neku vrstu online prevodioca, koji prevodi reč za reč. Postoji mogućnost prevoda određene reči na sve jezike iz baze kao i mogućnost prevoda na samo jedan od odabranih jezika. Sajt poseduje autentifikaciju, gde korisnik koji ima admin privilegije, moze da:• Dodaje nove admin usere• Dodaje nove podatke u bazu web servisa• Brise podatke iz baze web servisa• Edituje podatke iz baze web servisa
Obični korisnici su u mogućnosti da prevode reči. Metode su sledeće:
3.2.1 Organizacija lokalnog sajta
Slika 2 Organizaciona šema lokalnog sajta
10
3.2.2 Prikaz Translate
Stranica služi za prevod reči.Poseduje mogucnost prevoda reči na jedan jezik ili prevoda reči na sve jezike u bazi. Ukoliko korisnik traži prevod reči koja nije trenutno u bazi podataka dobiće obavestenje da reč ne postoji.
Slika 3 Prikaz translate strane lokalnog sajta
11
3.2.3 Prikaz Log In
Modalni prozor pisan u Java Script-u koji u koliko korisnik nije ulogovan daje opciju korisniku da se uloguje, a ukoliko je ulogovan, daje opciju korisniku da se izloguje.
Slika 4 Prikaz log in modalnog prozora lokalnog sajta
12
3.2.4 Prikaz Create Account
Stranica služi za kreiranje novog naloga. Ukoliko je rola usera admin on poseduje opciju kreiranja drugih admin korisnika, koji imaju dodatne opcije za razliku od normalnih korisnika.
Slika 5 Prikaz strane za kreiranje lokalnog sajta
13
3.2.5 Prikaz Admin Page
Stranica kojoj mogu da pristupe samo autorizovani korisnici sa ulogom admina. Na stranici imaju mogućnost:
Dodavanja novih reči u bazu web servisa Brisanje reči iz bare web servisa Editovanje reči iz baze web servisa

5 BAZA PODATAKA
Diplomski sadrži dve MySQL baze podataka koje su administrirane sa phpMyAdmin
alatom.
5.1 Web servis baza podataka
Slika 9 Struktura baze podataka web servera
63
5.1.1 Struktura baze podataka
Baza podataka sadrži sedam tabela, dok svaka tabela sadrži dve kolone. Jedna je id,
druga je reč.
5.2 Localhost sajt baza podataka
Slika 10 Struktura baze podataka lokalnog sajta
5.2.1 Struktura baze podataka
Postoje dve tabele, jedna je uloga, a druga je korisnik. Tabela uloga se sastoji od id-a i od uloge koju korisnik moze da poseduje.
Druga tabela je tabela korisnik koja sad sedam kolona: ID - id broj First_Name – Ime korisnika Last_Name – Prezime korisnika E-Mail – Email korisnika Username – Korisničko ime Password – Lozinka korisnika Role – Uloga korisnika ( pokazuje na tabelu uloga )

Napravljen je translate web servis koji je baziran na RESTful servisu čija je glavna funkcija
prevod prosleđenih reci na jedan od selektovanih jezika. Prevod reči je baziran na principu reč za reč i
trenutno podržava sedam jezika (Arapski, Nemački, Italijanski, Portugalski, Ruski i Španski).
Web servis poseduje pet različitih metoda koji komuniciraju sa bazom jezika od kojih dve
omogućavaju korisniku da trazi i dobije prevod tražene reči, a ostale tri omogucavaju privilegovanom
korisniku (adminu) ubacivanje, izmenu ili brisanje iz baze podataka web servisa. Servis je pisan u
Slim frameworku koji je veoma pogodan za handlovanje grešaka koji mogu da dodju prilikom
prosledjivanja parametra servisu ili greske prilikom kucanja url-a.
Uz diplomski je uradjen sajt koji komunicira sa web servisom, sa odvojenom zasebnom bazom
za korisnike. Sajt na najbolji način pokazuje funkcionalnost zasebnog web servisa.
Ovim diplomskim je napravljen web servis koji može da se koristi sa bilo kakvim sajtom koji
na dobri način koristi funkcije koje pruža taj web servis. U budućnosti web servis se može proširiti sa
većom bazom podataka tako da podržava vise od sedam jezika. Ili da se ubaci glasovna komunikacija
sa web servisom.
