纤细的框架消息:不存在可召唤的homecontroller

Question

项目结构

---

public/index.php

<?php

require __DIR__ . '/../vendor/autoload.php';
ini_set('display_errors', 'On');
if (PHP_SAPI == 'cli-server') {
    // To help the built-in PHP dev server, check if the request was actually for
    // something which should probably be served as a static file
    $url  = parse_url($_SERVER['REQUEST_URI']);
    $file = __DIR__ . $url['path'];
    if (is_file($file)) {
        return false;
    }
}

session_start();
// Instantiate the app
$settings = require __DIR__ . '/../src/settings.php';

$app = new SlimApp($settings);
// Set up dependencies
require __DIR__ . '/../src/dependencies.php';
// Register middleware
require __DIR__ . '/../src/middleware.php';
// Register routes
require __DIR__ . '/../src/routes.php';
// Run app
$app->run();

在这里我们有composer.json

{
"autoload":{
    "psr-4": {
        "App\": "src"
    }
},
"require": {
    "php": ">=5.5.0",
    "slim/slim": "^3.1",
    "slim/php-view": "^2.0",
    "monolog/monolog": "^1.17",
    "illuminate/database": "~5.1",
    "slim/twig-view": "^2.3"
},
"require-dev": {
    "phpunit/phpunit": ">=4.8 < 6.0"
},
"autoload-dev": {
    "psr-4": {
        "Tests\": "tests/"
    }
},
"config": {
    "process-timeout" : 0
},
}

这是我的控制器，我获得了名称空间的错误，在我看到的所有示例中，我都不知道该怎么做

<?php
namespace AppControllers;
class Homecontroller
{
    protected $container;
    // constructor receives container instance
    public function __construct(ContainerInterface $container) {
        $this->container = $container;
    }
    public function home($request, $response, $args) {
        echo "locura";
        // your code
        // to access items in the container... $this->container->get('');
        return $response;
    }
    public function contact($request, $response, $args) {
        // your code
        // to access items in the container... $this->container->get('');
        return $response;
    }
}

---

实际配置在我的routes.php中，我把以下内容：

$app->get('/new', Homecontroller::class . ':home');

---

在配置之前

在上面的代码中，我尝试将控制器创建到容器中，然后使用

$app->get('/new', 'HomeController:home');

和dependencies.php我放了此代码：

$container['HomeController'] = function($c) {
$view = $c->get("view"); // retrieve the 'view' from the container
return new HomeController($view);

};

，但我没有获得任何配置的结果

我想从路由器加载homecontroller

这是我放置 api.powertv/new

时遇到的错误

 Type: RuntimeException
 Message: Callable Homecontroller does not exist
File:       /Users/alfonso/Sites/powertv_api/vendor/slim/slim/Slim/CallableResolver.php
Line: 90

我来这里，我把这篇文章像我的最后一个资源一样，如果失败了，我不知道我会做什么。

Answer 1

尝试在您的：

中使用绝对的名称空间路径

1. dependencies.php

    $ container ['yourcontroller'] =函数（$ c）{  $ view = $ c ['view'];  返回新 app  controllers  yourcontroller（$ view）;}

2. routes.php

     $ app-> get（'your_defined_route_name'， app  controllers  yourcontroller :: class。'：yourcontrollermethod'）;

Answer 2

容器内的名称和您在路由中使用的人必须匹配您已将容器键设置为HomeController并在路线中使用的HomeController，这些字符串不等。

自我创建字符串

$container['HomeController'] = function($c) {
    $view = $c->get("view"); // retrieve the 'view' from the container
    return new HomeController($view);
};
$app->get('/new', 'HomeController:home');

或将::class语法用于两者：

$container[HomeController::class] = function($c) {
    $view = $c->get("view"); // retrieve the 'view' from the container
    return new HomeController($view);
};
$app->get('/new', [HomeController::class, 'home');
// or $app->get('/new', HomeController::class . ':home');

Answer 3

带有pheara的答案，我获得了另一个错误，是下一个错误：

Type: Error
Message: Undefined constant 'Appcontrollers'
File:/Users/alfonso/Sites/powertv_api/src/Controllers/HomeController.php
Line: 5

错误的跟踪是下一个：

要解决此错误，您必须将命名空间放在3行中：

<?php 
namespace [yournamespace]
//rest of your controller
