Laravel

Question

所以我有一个 App\bindings.php 文件，我已将其添加到我的 composer.json 文件中：

"autoload": {
    "files": [
        "app/bindings.php"
    ]
},

在这个文件中，我尝试像这样为我的存储库设置绑定：

<?php 

function getRepoBinding($id)
{
    $repo = "{$id}Repository";

    $clientName = strtoupper(config('client.name'));
    $implementation = config('app.repo_implementation', 'Eloquent');
    $clientOverride = "App\Overrides\{$clientName}\Repositories\{$implementation}\{$repo}";
    $repo = class_exists($clientOverride) ? $clientOverride : "App\Repositories\{$implementation}\{$repo}";
    return $repo;
}
// Repository Interface Bindings
dd(getRepoBinding('Contribution'));
App::bind('ContributionIneterface', getRepoBinding('Contribution'));

但是，我运行一个 composer dump-auto 并尝试运行我的应用程序，但我收到以下错误：

Fatal error: Uncaught Error: Call to a member function make() on null in /home/vagrant/Code/famsapi/vendor/laravel/framework/src/Illuminate/Foundation/helpers.php:54

它似乎与全局配置帮助程序方法有关...但我不确定如何解决该问题。更好的是，如果你知道我如何以另一种方式做到这一点，我会洗耳恭听。

这是因为您在应用程序启动之前加载了该文件。

在您的 AppServiceProvider 中使用它
