如何覆盖 laravel 照亮 ServiceProvider

Question

我升级了 php 版本，现在从 vendor/illuminate/support/ServiceProvider.php 调用 loadViewsFrom 方法 生成错误，因为 $this->app->config['view'] 不是数组。

protected function loadViewsFrom($path, $namespace)
{
    if (is_array($this->app->config['view']['paths'])) {
        foreach ($this->app->config['view']['paths'] as $viewPath) {
            if (is_dir($appPath = $viewPath.'/vendor/'.$namespace)) {
                $this->app['view']->addNamespace($namespace, $appPath);
            }
        }
    }

    $this->app['view']->addNamespace($namespace, $path);
}

如何在不升级 laravel 版本且不修改供应商文件的情况下解决此问题？

我试图从 composer autoload 覆盖地图类并运行 composer dump-autoload，但没有成功。

我的作曲家是这样的：

...
"autoload": {
    "exclude-from-classmap": ["vendor/illuminate/support/ServiceProvider.php"],
    "psr-4": {
        "App\\": "app/",
        "Illuminate\\": "app/illuminate/"
    }
},
...

在 app/illuminate/support 我添加了我的自定义 ServiceProvider.php。

另外，我尝试在 bootstrap/app.php 中映射：

$app->singleton(
    Illuminate\Support\ServiceProvider::class,
    App\illuminate\support\ServiceProvider::class
);

供应商类仍在使用。

框架和php版本：

Laravel Framework Lumen (5.6.4) (Laravel Components 5.6.*)

php version: 7.4.13

如果$this->app->config['view'] 不是数组，那么您的问题出在您的config/view.php 文件中。

默认情况下，此文件如下所示

<?php

return [

    /*
    |--------------------------------------------------------------------------
    | View Storage Paths
    |--------------------------------------------------------------------------
    |
    | Most templating systems load templates from disk. Here you may specify
    | an array of paths that should be checked for your views. Of course
    | the usual Laravel view path has already been registered for you.
    |
    */

    'paths' => [
        resource_path('views'),
    ],

    /*
    |--------------------------------------------------------------------------
    | Compiled View Path
    |--------------------------------------------------------------------------
    |
    | This option determines where all the compiled Blade templates will be
    | stored for your application. Typically, this is within the storage
    | directory. However, as usual, you are free to change this value.
    |
    */

    'compiled' => env(
        'VIEW_COMPILED_PATH',
        realpath(storage_path('framework/views'))
    ),

];

如您所见，返回了 array。所以你应该更好地解决这个问题，而不是覆盖服务提供者。
