Silex找不到控制器类 - Silex can't find Controller Class

Silex can't find Controller Class

本文关键字：控制器找不到 Silex | 更新日期: 2023-09-26

项目目录结构

/composer.json
/web/index.php
/app/controller/IndexController.php

composer.json

{
  "require" : {
    "silex/silex": "*"
  },
  "autoload": {
    "psr-0": {
            "": "./"
        }
  }
}

index . php

<?php
require_once __DIR__.'/../vendor/autoload.php';
use Silex'Application;
$app = new Application();
$app['debug'] = true;
$app->get('/', 'App''Controller''IndexController::getIndex');
$app->run();

IndexController.php

<?php
namespace App'Controller;
use Silex'Application;
class IndexController
{
    public function getIndex(Application $app)
    {
        return "You got the index, congrats!";
    }
}

每当我

cd web/
php -S localhost:8080
curl http://localhost:8080

从项目根目录我得到以下异常

InvalidArgumentException in ControllerResolver.php line 153:
Class "App'Controller'IndexController" does not exist.
in ControllerResolver.php line 153
at ControllerResolver->createController('App'Controller'IndexController::getIndex') in ControllerResolver.php line 80
at ControllerResolver->getController(object(Request)) in HttpKernel.php line 135
at HttpKernel->handleRaw(object(Request), '1') in HttpKernel.php line 68
at HttpKernel->handle(object(Request), '1', true) in Application.php line 581
at Application->handle(object(Request)) in Application.php line 558
at Application->run() in index.php line 12

这对我来说毫无意义。这个程序实际上在我的MacBook上运行得很好，但是当我把它部署到我的Ubuntu VPS上时，我得到了上面的异常，尽管在两个环境中运行的代码是相同的。为什么Silex找不到我的控制器?

在我的例子中，我错过了use Symfony'Component'HttpFoundation'Request;行。

从这篇文章:

检查你的控制器是否有这个:

使用Silex '应用;

使用Symfony ' HttpFoundation ' '组件请求;

try this

"autoload" : {
    "psr-4" : {
        "App''Controller''" : "app/controller/"
    }
}

这是一个大小写问题。我的macbook有一个不区分大小写的文件系统，我的Linux VPS有一个区分大小写的文件系统，所以当部署到VPS时，我不得不在我的项目中大写目录，以便Silex可以正确地解析控制器。
