Slim3 - 传递给构造函数的参数 1 必须是 Slim\Views\Twig 的实例

Question

我正在使用 Slim3，但在注册依赖项时遇到问题。根据错误，我创建的构造函数期望参数 1 的类型为 Slim\Views\Twig.

问题是我正在传递 Slim\Views\Twig 的实例 - 至少我认为是。我已经几个月没有使用 Slim，所以我可能遗漏了一些明显的东西。尽管如此，我还是找不到问题。

我得到的错误是：

Catchable fatal error:  Argument 1 passed to App\Controllers\RegistrationController::__construct() must be an instance of Slim\Views\Twig, instance of Slim\Container given

controllers/RegistrationController.php

<?php

namespace App\Controllers;

class RegistrationController {
  protected $view;

  public function __construct(\Slim\Views\Twig $view) {
    $this->view = $view;
  }

  public function register($request, $response, $args) {
    // Does some stuff ...
  }
}

dependencies.php

<?php

use \App\Controllers\RegistrationController;

$container = $app->getContainer();

// Twig View
$container['view'] = function ($c) {
    $settings = $c->get('settings')['renderer'];
    $view = new \Slim\Views\Twig($settings['template_path']);
    $basePath = rtrim(str_ireplace('index.php', '', $c['request']->getUri()->getBasePath()), '/');
    $view->addExtension(new Slim\Views\TwigExtension($c['router'], $basePath));
    return $view;
};

// monolog
$container['logger'] = function ($c) {
    $settings = $c->get('settings')['logger'];
    $logger = new Monolog\Logger($settings['name']);
    $logger->pushProcessor(new Monolog\Processor\UidProcessor());
    $logger->pushHandler(new Monolog\Handler\StreamHandler($settings['path'], $settings['level']));
    return $logger;
};

// sqlite3
$container['db'] = function ($c) {
    return new SQLite3(__DIR__ . '/../db/prod.db');
};

// Registration Controller
$container['RegistrationController'] = function($c) {
  return new RegistrationController($c->get('view'));
};

路线

$app->post('/signup', '\App\Controllers\RegistrationController:register');

还尝试了以下方法：

$app->post('/signup', \App\Controllers\RegistrationController::class . ':register');

有什么想法吗？

Answer 1

问题是我错误地定义了路线，我完全错过了 Container Resolution

上的部分

它应该是这样的：

$app->post('/signup', 'RegistrationController:register');
