Question

所以我一直从我的app.php中收到此错误，并且不知道发生了什么。我正在关注有关如何在php中制作购物车的教程。我将保留代码和错误文本，也许你们有一个主意。

错误文字：

致命错误：未捕获的错误：找不到“ Cart \ App”类 C：\ xampp \ htdocs \ cart \ bootstrap \ app.php：11堆栈跟踪：＃0 C：\ xampp \ htdocs \ cart \ public \ index.php（3）：require（）＃1 {main}抛出在第11行的C：\ xampp \ htdocs \ cart \ bootstrap \ app.php中

为节省您一些时间，错误来自$ app =新应用；

代码：

<?php

use Cart\App;
use Slim\Views\Twig;
use Illuminate\Database\Capsule\Manager as Capsule;

session_start();

require __DIR__ . '/../vendor/autoload.php';

$app = new App;

$container = $app->getContainer();

$capsule = new Capsule;
$capsule->addConnection([
    'driver' => 'mysql',
    'host' => 'localhost',
    'database' => 'cart',
    'username' => 'root',
    'password' => '',
    'charset' => 'utf8',
    'collation' => 'utf8_unicode_ci',
    'prefix' => ''
]);

$capsule->setAsGlobal();
$capsule->bootEloquent();

Braintree_Configuration::environment('sandbox');
Braintree_Configuration::merchantId('MERCHANT_ID');
Braintree_Configuration::publicKey('PUBLIC_KEY');
Braintree_Configuration::privateKey('PRIVATE_KEY');

require __DIR__ . '/../app/routes.php';

$app->add(new \Cart\Middleware\ValidationErrorsMiddleware($container->get(Twig::class)));
$app->add(new \Cart\Middleware\OldInputMiddleware($container->get(Twig::class)));

Answer 1

use语句必须在autoload.php导入之后

Answer 2

9个小时后，我解决了它，因为它是拼写错误的名称，而不是我写的Nmae，所以对于每个有此问题的人，请检查所有您必须正确纠正的名称和类，这是唯一的解决方法
