如何通过PHP和Vue实现员工考勤的请假功能

// 员工请假列表接口
$app->get('/leaves', function($request, $response, $args) {
    $db = $this->get('db');

    $leaves = $db->table('leaves')
        ->join('employees', 'leaves.employee_id', '=', 'employees.id')
        ->select('leaves.*', 'employees.name')
        ->get();

    return $response->withJson($leaves);
});

// 创建员工请假记录接口
$app->post('/leaves', function($request, $response, $args) {
    $db = $this->get('db');
    $data = $request->getParsedBody();

    $leave = $db->table('leaves')->insert([
        'employee_id' => $data['employee_id'],
        'leave_type' => $data['leave_type'],
        'start_date' => $data['start_date'],
        'end_date' => $data['end_date'],
        'status' => '待审批'
    ]);

    return $response->withJson(['success' => true]);
});

// 更新员工请假记录接口
$app->put('/leaves/{id}', function($request, $response, $args) {
    $db = $this->get('db');
    $data = $request->getParsedBody();

    $leave = $db->table('leaves')->where('id', $args['id'])->update([
        'status' => $data['status']
    ]);

    return $response->withJson(['success' => true]);
});
