某些方法无法解决

Question

从事API项目。一切都很好，直到我必须添加一个新端点（也有新方法）并且我的新端点遇到此错误，另一个端点运行良好。下面是错误日志：

我的新端点的路由：

$app->get('/user/notification', 'UserController:getNotification');

我的班级：

class UserController{
    public function __construct($container)
    {
        // make the container available in the class
        $this->container = $container;
    }

    public function getNotification($request, $response, $args){
        //my code here
    }
}

我的dependencies.php：

use App\Controllers\UserController;
$container = $app->getContainer();
$container['UserController'] = function ($c) {
    return new UserController($c);
};

我的composer.json

{
    "name": "slim/slim-skeleton",
    "autoload": {
        "psr-4": {
           "App\\": "src/"
        }
    }
}

尝试到composer dump-autoload，但没有用。

Answer 1

PHP无法找到您的类。

1. 在index.php中要求它
2. 修复您的PSR-0 / 4自动加载架构，然后转储-自动加载

Answer 2

[rsync到服务器时不小心。我上传到错误的目录Controller而不是Controllers。

Answer 3

我有一个类似的问题，我到了那里。就我而言，Slim无法实例化Controller类，因为它只是拼写错误。

Answer 4

根据提供的代码，

'UserController:getNotification'不是有效的可调用对象。使用静态函数'UserController::getNotification'或构造UserController并将array($controller, "getNotification")传递给$app->get()。
