CodeIgniter 4命名空间重复自身:找不到控制器或其方法:\\App\\Controllers\\App\\Controllers\\TypeBloodController::index

我无法使用CodeIgniter 4框架创建Restful API。
我使用$routes->resource()来定义方法。但是,我无法获得http://localhost:8080/type-blood和其他地址来返回我想要的。
我正确地配置了项目中的数据库,并选择查看数据。
《 Postman 》给我的回报是:

说明

如果提供的控制器没有前导反斜杠(\),则默认名称空间将被前置。
默认命名空间
当路由器匹配一个控制器时,路由器会在路由器指定的控制器前面添加默认的命名空间值。默认情况下,该值为App\Controllers

摘自CodeIgniter4/app/Config/Routing.php

class Routing extends BaseRouting
{
    // ...
    public string $defaultNamespace = 'App\Controllers';
    // ...
}

字符串
如果设置值为空字符串(“),它会让每个路由指定完全命名空间的控制器:

解决方案

app/Config/Routes.php
1.将默认命名空间设置为空字符串(“)。例如:$routes->setDefaultNamespace('');

  • 将所有基于字符串的控制器语法转换为数组可调用语法。例如:
    • 而不是:* $routes->get('/', 'Home::index');
    • 用途:铝 * $routes->get('/', [Home::class, 'index']);
  • 数组可调用语法(Since v4.2.0.)还允许在使用IDE或代码编辑器时快速导航到方法或控制器。

示例

<?php

use CodeIgniter\Router\RouteCollection;
use App\Controllers\TypeBloodController;
use App\Controllers\Home;

/**
 * @var RouteCollection $routes
 */
$routes->setDefaultNamespace('');

$routes->get('/', [Home::class, 'index']);

$routes->resource('type-blood', ['controller' => TypeBloodController::class]);

不幸的是,你不能使用限定名来指定 * 控制器 * 选项。根据文档,这是可能的,但这似乎是一个小错误,因为在这种情况下,它重复了命名空间。
你总是可以用spark命令检查你的路由。检查处理程序列。

php spark routes

字符串
在我的例子中,处理程序是:\App\Controllers\App\Controllers\Home::index,但它应该是:\App\Controllers\Home::index
你可以简单地修复它:

$routes->resource('type-blood', ['controller' => 'TypeBloodController']);


注意事项:如果你的资源和控制器名称相同,你可以省略 controller 选项。所以你可以在技术上将控制器的名称改为 TypeBlood,文件名改为 TypeBlood.php。然后简单地删除 controller 选项。
注意:如果您的控制器不在App\Controllers命名空间中,您可以使用 namespace 选项指定。例如:

$routes->resource('type-blood', ['controller' => 'TypeBloodController', 'namespace' => 'NotApp\Controllers']);


我创建了一个bug issue report,所以可能会在以后的版本中得到修复。

更新:文档将在以后的版本中得到改进。您可以使用以下(完全限定名称),而无需更改 default namespace 配置:

$routes->resource('test1', ['namespace' => '\\', 'controller' => Home::class]);
$routes->resource('test2', ['controller' => '\\' . Home::class]);
$routes->resource('test3', ['controller' => 'Home']);
