php - 中未找到自动加载 PSR-4 命名空间接口(interface)

Question

{ 
       "autoload": {

       "psr-4": {
        "Acme\\": "src"
    }
}
}

我的 composer.json 文件

namespace Acme;

Interface Responds
{   
    public function userRegisteredSuccessfuly();

    public function userRegisteredunSuccessfuly();  
}

接口(interface)位于 C:\xampp\htdocs\bootcamp\src\respondstouserregistration.php

<?php 
namespace Acme;

class RegisterUser
{
    public function execute(array $data, Responds $listener) //data 
    {
        var_dump('registering the user.');
        $listener->userRegisteredSuccessfuly();
    }
}

在我引用的接口(interface)响应的 RegisterUser 中， registeruser 也位于 src

<?php 
namespace Acme;

class AuthController implements Responds
{
    protected $registration;

    public function __construct(RegisterUser $registration)
    {
        $this->registration = $registration;
    }

    public function register()
    {
        $this->registration->execute([], $this);
    }

    public function userRegisteredSuccessfuly()
    {
        var_dump('created successfuly. redirect somewhere.');
    }


    public function userRegisteredunSuccessfuly()
    {
        var_dump('created unsuccessfuly. redirect back.');
    }

}

在这个类中，我实现了响应接口(interface)。

AuthController 也位于 C:\xampp\htdocs\bootcamp\src\authcontroller.php

现在我的错误是

PHP Fatal error: Interface 'Acme\Responds' not found in C:\xampp\htdocs\bootcamp\src\authcontroller.php How can i make the Authcontroller locate the php file where the interface is?

PSR-4 自动加载假定您的类名与文件名匹配。所以你的 Interface Responds预计在responds.php文件，不在 respondstouserregistration.php文件。重命名文件，或将您的界面重命名为 Interface Respondstouserregistration
