PHP与REST API项目实战：从入门到进阶

composer require slim/slim
composer require doctrine/orm

<?php
namespace App\Model;

use Doctrine\ORM\Mapping as ORM;

/** @ORM\Entity */
class User {
    /** @ORM\Id @ORM\GeneratedValue @ORM\Column(type="integer") */
    private $id;

    /** @ORM\Column(type="string") */
    private $name;
    
    // ...
}

<?php
use Slim\App;
use App\Model\User;

$app = new App();

$app->get('/users', function ($request, $response) {
    // 获取所有用户
    $users = $entityManager->getRepository(User::class)->findAll();
    return $response->withJson($users);
});

<?php
use Respect\Validation\Validator as v;

$validation = v::key('name', v::stringType()->notEmpty());
if (!$validation->validate($request->getParsedBody())) {
    return $response->withJson(['error' => 'Invalid name'], 400);
}

<?php
$app->add(new \Slim\Middleware\ErrorMiddleware([
    'displayErrorDetails' => true
]));

<?php
use App\Model\User;

$user = new User();
$user->setName($request->getParsedBody()['name']);
$entityManager->persist($user);
$entityManager->flush();

<?php
use App\Model\User;

$users = $entityManager->getRepository(User::class)->findAll();

<?php
use App\Model\User;

$user = $entityManager->getRepository(User::class)->find($request->getAttribute('id'));
