Slim 框架消息:Callable Homecontroller 不存在 [英] Slim framework Message: Callable Homecontroller does not exist

问题描述

项目结构

<小时>

public/index.php

run();

<小时>

这里有 composer.json

<代码>{自动加载":{psr-4":{应用程序\\":源代码"}},要求": {"php": ">=5.5.0","slim/slim": "^3.1","slim/php-view": "^2.0","独白/独白": "^1.17",照亮/数据库":~5.1"，"slim/twig-view": "^2.3"},需要开发":{"phpunit/phpunit": ">=4.8 < 6.0"},自动加载开发":{psr-4":{"测试\\": "测试/"}},配置":{进程超时":0},}

<小时>

这是我的控制器，我得到了命名空间错误，并且在我看到的所有示例中都使用了它，所以..我不知道该怎么做

container = $container;}公共函数家($request，$response，$args){echo "locura";//你的代码//访问容器中的项目... $this->container->get('');返回 $response;}公共函数联系($request，$response，$args){//你的代码//访问容器中的项目... $this->container->get('');返回 $response;}}

<小时>

实际配置在我的 routes.php 中，我已经把这个:

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

<小时>

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 = $c->get("view");//从容器中检索视图"返回新的 HomeController($view);

};

但是我没有得到任何配置的结果

<小时>

我想从路由器加载 HomeController

这是我在输入 api.powertv/new

时遇到的错误

 类型:RuntimeException消息:Callable Homecontroller 不存在文件:/Users/alfonso/Sites/powertv_api/vendor/slim/slim/Slim/CallableResolver.php线路:90

我来了，我把这篇文章当作我的最后一个资源，如果失败了我不知道我要做什么.

解决方案

尝试在您的:

1. dependencies.php

   <前>$container['yourController'] = function ($c) {$view = $c['view'];返回新的 \App\Controllers\YourController($view);}

2. routes.php

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

Project Structure

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';



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

Here we have the 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
},
}

Here is my controller, i obtain a error with the namespace and in all the examples that i have seen use this so.. I don't know what to do more

<?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;
    }
}

---

Actual configuration In my routes.php I have put this:

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

---

Before configuration

In the above code, I tried to create the controller into the container, and then use

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

And in the dependencies.php I put this code:

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

};

but I didn't obtain any result with any configuration

---

I would like to load the HomeController from router

This is the error that I have when I put api.powertv/new

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

i come here, and I put this post like my last resource, if this fails I don't know what I am going to do.

解决方案

Try to use absolute namespace path in your:

1. dependencies.php

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

2. routes.php

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