在本教程中，我们将使用 Lithe 创建一个工作的 TodoList 应用程序。您将学习如何构建项目、创建交互式视图以及实施 RESTful API 来管理您的任务。该项目将作为如何使用 PHP 构建现代 Web 应用程序的绝佳示例。
首先，让我们创建一个新的 Lithe 项目：
composer create-project lithephp/lithephp todo-app cd todo-app
使用以下设置编辑项目根目录中的 .env 文件：
DB_CONNECTION_METHOD=mysqli DB_CONNECTION=mysql DB_HOST=localhost DB_NAME=lithe_todos DB_USERNAME=root DB_PASSWORD= DB_SHOULD_INITIATE=true
运行命令来创建新的迁移：
php line make:migration CreateTodosTable
在 src/database/migrations/ 中编辑生成的迁移文件：
return new class
{
public function up(mysqli $db): void
{
$query = "
CREATE TABLE IF NOT EXISTS todos (
id INT(11) AUTO_INCREMENT PRIMARY KEY,
title VARCHAR(255) NOT NULL,
completed BOOLEAN DEFAULT FALSE,
created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
)
";
$db->query($query);
}
public function down(mysqli $db): void
{
$query = "DROP TABLE IF EXISTS todos";
$db->query($query);
}
};
运行迁移：
php line migrate
生成一个新模型：
php line make:model Todo
编辑文件 src/models/Todo.php:
namespace App\Models;
use Lithe\Database\Manager as DB;
class Todo
{
public static function all(): array
{
return DB::connection()
->query("SELECT * FROM todos ORDER BY created_at DESC")
->fetch_all(MYSQLI_ASSOC);
}
public static function create(array $data): ?array
{
$stmt = DB::connection()->prepare(
"INSERT INTO todos (title, completed) VALUES (?, ?)"
);
$completed = false;
$stmt->bind_param('si', $data['title'], $completed);
$success = $stmt->execute();
if ($success) {
$id = $stmt->insert_id;
return [
'id' => $id,
'title' => $data['title'],
'completed' => $completed
];
}
return null;
}
public static function update(int $id, array $data): bool
{
$stmt = DB::connection()->prepare(
"UPDATE todos SET completed = ? WHERE id = ?"
);
$stmt->bind_param('ii', $data['completed'], $id);
return $stmt->execute();
}
public static function delete(int $id): bool
{
$stmt = DB::connection()->prepare("DELETE FROM todos WHERE id = ?");
$stmt->bind_param('i', $id);
return $stmt->execute();
}
}
生成一个新的控制器：
php line make:controller TodoController
编辑文件 src/http/controllers/TodoController.php:
namespace App\Http\Controllers;
use App\Models\Todo;
use Lithe\Http\Request;
use Lithe\Http\Response;
class TodoController
{
public static function index(Request $req, Response $res)
{
return $res->view('todo.index');
}
public static function list(Request $req, Response $res)
{
$todos = Todo::all();
return $res->json($todos);
}
public static function store(Request $req, Response $res)
{
$data = (array) $req->body();
$todo = Todo::create($data);
$success = $todo ? true : false;
return $res->json([
'success' => $success,
'message' => $success ? 'Tarefa criada com sucesso' : 'Falha ao criar tarefa',
'todo' => $todo
]);
}
public static function update(Request $req, Response $res)
{
$id = $req->param('id');
$data = (array) $req->body();
$success = Todo::update($id, $data);
return $res->json([
'success' => $success,
'message' => $success ? 'Tarefa atualizada com sucesso' : 'Falha ao atualizar tarefa'
]);
}
public static function delete(Request $req, Response $res)
{
$id = $req->param('id');
$success = Todo::delete($id);
return $res->json([
'success' => $success,
'message' => $success ? 'Tarefa removida com sucesso' : 'Falha ao remover tarefa'
]);
}
}
创建src/views/todo目录并添加index.php文件：
<!DOCTYPE html>
<html>
<head>
<title>TodoList com Lithe</title>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">

Configurando as Rotas
</h2>
<p>Atualize o arquivo src/App.php para incluir as rotas da TodoList:<br>
</p>
<pre class="brush:php;toolbar:false">use App\Http\Controllers\TodoController;
$app = new \Lithe\App;
// Rota para a página principal
$app->get('/', [TodoController::class, 'index']);
// Rotas da API
$app->get('/todos/list', [TodoController::class, 'list']);
$app->post('/todos', [TodoController::class, 'store']);
$app->put('/todos/:id', [TodoController::class, 'update']);
$app->delete('/todos/:id', [TodoController::class, 'delete']);
$app->listen();
要启动开发服务器，请运行：
php line serve
在浏览器中访问 http://localhost:8000 查看运行中的应用程序。
我们的 TodoList 具有以下功能：
