mkdir app01
cd app01

Telepítjük az aktuális könyvtárba a Leaf-t a vendor könyvtárba.

composer require leafs/leaf

A parancs után létrejön egy vendor nevű könyvtár. A leaf ebbe könyvtárba kerül függőségként.

Szükségünk van egy $app objektumra, amivel létrehozhatjuk az útválsztást:

index.php

<?php
 
require __DIR__ . '/vendor/autoload.php';
 
$app = new Leaf\App;
 
$app->get('/msg', function() use($app) {
    $app->response()->json(['msg' => 'Hi!']);
});
 
$app->run();

Az $app objektum helyett használhatjuk az app() függvényt:

index.php

<?php
 
require __DIR__ . '/vendor/autoload.php';
 
 
app()->get('/msg', function() {
    response()->json(['msg' => 'Hi!']);
});
 
app()->run();

php -S localhost:8000 -t .

Tesztelés HTTPie kliens segítségével:

http localhost:8000/msg

Hozzunk létre, például a projekt gyökérkönyvtárában egy EmplyoeeController.php fájlt:

EmployeeController.php

<?php
 
class EmployeeController {
    public function index() {
        response()->json('műkszik');
    }
}

index.php

<?php
require __DIR__ . '/vendor/autoload.php';
 
$app = new Leaf\App;
 
require "EmployeeController.php";
 
$app->get('/employees', 'EmployeeController@index');
 
$app->run();

index.php

<?php
require __DIR__ . '/vendor/autoload.php';
require 'api.php';
app()->run();

api.php

<?php
 
require "EmployeeController.php";
 
$app = new Leaf\App;
$app->get('/employees', 'EmployeeController@index');

EmployeeController.php

<?php
 
class EmployeeController {
    public function index() {
        response()->json('műkszik');
    }
}

composer require leafs/db

db()->connect([
  'dbtype' => 'sqlite',
  'dbname' => 'db.sqlite',
]);

// syntax
db()->connect('hostname', 'dbnev', 'user', 'titok', 'mysql');

Lekérdezés:

$emps = db()->query('SELECT * FROM employees')->all();

drop table if exists employees;
create table employees (
    id int unsigned not null primary key auto_increment,
    name varchar(50),
    city varchar(50),
    salary double,
    created_at timestamp default current_timestamp,
    updated_at timestamp default current_timestamp on update current_timestamp
);

Célszer a kontrollerek számára készíteni egy app/controllers könyvtárat. A TodoController osztályban a konstruktorban állítsuk be az SQLite-t:

app/controllers/TodoController.php

<?php
 
class TodoController {
  public function __construct() {
    db()->connect([
      'dbtype' => 'sqlite',
      'dbname' => 'db.sqlite'
    ]);
  }
  public function index() {
    $todos = db()->select('todos')->all();
    response()->json($todos);
  }
 
  public function create() {
    $res = db()
    ->insert('todos')
    ->params([request()->body()])
    ->execute();
 
    $id = db()->lastInsertId();
    $todo = db()->select('todos')->where('id', $id)->first();
    response()->json($todo);
  }
 
  public function update($id) {
    $res = db()
    ->update('todos')
    ->params(request()->body())
    ->where('id', $id)
    ->execute();
    $todo = db()->select('todos')->where('id', $id)->first();
    response()->json($todo);
  }
 
  public function delete($id) {
    $res = db()
    ->delete('todos')
    ->where('id', $id)
    ->execute();
    response()->json($res);
  }
}

app/routes/api.php

<?php
 
require "app/controllers/TodoController.php";
 
app()->get('/api/todos', 'TodoController@index');
app()->post('/api/todos', 'TodoController@create');
app()->put('/api/todos/{id}', 'TodoController@update');
app()->delete('/api/todos/{id}', 'TodoController@delete');

composer require leafs/auth

app/controllers/AuthController.php

<?php
 
class AuthController {
  public function __construct() {
    auth()->connect('', 'db.sqlite', '', '', 'sqlite');
  }
 
  public function login() {
    $data = auth()->login([
      'username' => request()->get('username'),
      'password' => request()->get('password')
    ]);
    response()->json(['auth' => $data]);
  }
  public function register() {
    $data = auth()->register([
      'username' => request()->get('username'),
      'password' => request()->get('password')
    ], ['username']);
 
    if(!$data) {
      $data = auth()->errors();
    }
    response()->json(['auth' => $data]);
 
  }
}

app/middlewares/Auth.php

<?php
 
auth()->connect('', 'db.sqlite', '', '', 'sqlite');
 
app()->registerMiddleware('auth', function () {
  $id = auth()->id();
  if (!$id) {
    response()->exit([
      'status' => 'error',
      'message' => 'Not authorized'
      ], 401);
  }
});

app/routes/api.php

<?php
 
require "app/controllers/TodoController.php";
require "app/controllers/AuthController.php";
require "app/middlewares/Auth.php";
 
app()->get('/api/todos', 'TodoController@index');
 
app()->post('/api/login', 'AuthController@login');
app()->post('/api/register', 'AuthController@register');
 
app()->group('/', ['middleware' => 'auth', function () {
  app()->post('/api/todos', 'TodoController@create');
  app()->put('/api/todos/{id}', 'TodoController@update');
  app()->delete('/api/todos/{id}', 'TodoController@delete');    
}]);

composer require leafs/cors

vagy:

leaf install cors

index.php

<?php
 
require __DIR__ . '/vendor/autoload.php';
 
require 'app/routes/api.php';
 
app()->cors();
app()->run();

Beállítás:

app()->cors([
  'origin' => 'http://example.com',
  'optionsSuccessStatus' => 200
]);
