Question

公开/ index.php的

<?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';



$app = new \Slim\App($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();

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，我得到了命名空间的错误，在我看到的所有示例中都使用了这个...我不知道该怎么做

<?php

namespace \App\Controllers;

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中我已经说明了这一点：

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

配置前

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');

在dependencies.php中我放了这段代码：

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

};

但我没有通过任何配置获得任何结果

我想从路由器加载HomeController

这是我把 api.powertv / new

时的错误

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

我来到这里，我把这篇文章写成我最后的资源，如果失败我不知道自己要做什么。

Answer 1

尝试在：

中使用绝对命名空间路径

dependencies.php

 $container['yourController'] = function ($c) {
  $view = $c['view'];
  return new \App\Controllers\YourController($view);
}

routes.php文件

  $app->get('your_defined_route_name', \App\Controllers\YourController::class . ':YourControllerMethod');

Answer 2

容器内的名称和您在路径中使用的人员必须匹配您已将容器密钥设置为HomeController并在路由中使用\HomeController，这些字符串不相等。

要么自己创建字符串

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

或使用::class语法：

$container[HomeController::class] = function($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

在Pheara的回答中我得到了另一个错误，是下一个错误：

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

错误的痕迹是下一个：

要解决此错误，您必须将命名空间放在第3行：

<?php 

namespace [yournamespace]

//rest of your controller

Slim框架消息：Callable Homecontroller不存在
