某些方法无法解析

Question

处理 API 项目。一切都很好，直到我必须添加新端点（也是新方法）并且我的新端点出现此错误，另一个端点运行良好。以下是错误日志：

我的新终结点的路由：

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

我的composer.json

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

试图composer dump-autoload但没有奏效。

Answer 1

PHP 找不到你的类。

1. 在索引中需要它.php
2. 修复 PSR-0/4 自动加载架构，然后转储自动加载

Answer 2

rsync服务器

时不小心。我上传到错误的目录Controller而不是Controllers.

Answer 3

我遇到了类似的问题，我到了那里。就我而言，Slim 无法实例化控制器类，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'或构造用户控制器并将array($controller, "getNotification")传递给$app->get()。
