Question

我使用的是Slim3，但我在注册依赖项时遇到了问题。根据错误，我创建的构造函数需要参数1的类型为Slim\Views\Twig。

问题是我正在传递Slim\Views\Twig的实例 - 至少我认为我是。我在几个月内没有使用过Slim，所以我可能会遗漏一些明显的东西。从来没有我能找到问题。

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

控制器/ 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');

还尝试了以下内容：

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

有什么想法吗？

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

上的部分

以下是它的外观：

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

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