AliasLoader 在 Laravel 中找不到 Facade

Facade not found by AliasLoader in Laravel

我在 'aliases'

下的 laravel 项目中为我的 'config/app.php' 添加了自定义外观

'GeoLocation' => '\App\Facades\GeoLocation',

自定义class的文件夹在'app/Facades/GeoLocation.php',服务提供商在'app/Providers/GeoLocationServiceProvider.php'

如何在 app.php 中声明正确的别名才能正确加载 Facade?错误信息是:

ErrorException in AliasLoader.php line 63: Class 'Facades\GeoLocation' not found

这是我的门面:

<?php namespace App\Facades;
use Illuminate\Support\Facades\Facade;

class GeoLocation extends Facade {
    protected static function getFacadeAccessor() { return 'geolocation'; }
}

会不会是我服务商的return值不对?

<?php namespace App\Providers;

use Illuminate\Support\ServiceProvider;

class GeoLocationServiceProvider extends ServiceProvider {

    public function register() {

        \App::bind('geolocation', function()
        {
            return new GeoLocation;
        });
    }
}

为了测试,我创建了另一个名为自定义函数的服务提供者:

<?php namespace App\Helpers;

class CustomFunction {
    //Generate random float between -1 and 1
    function f_rand($min = 0, $max = 1, $mul = 1000000) {
        if ($min>$max) return false;
        return mt_rand($min*$mul, $max*$mul) / $mul;
    }

    function test() {
        echo "OK";
    }
}

<?php namespace App\Providers;

use Illuminate\Support\ServiceProvider;

class CustomFunctionServiceProvider extends ServiceProvider {

    public function register() {

        \App::bind('customfunctions', function()
        {
            return new CustomFunction;
        });
    }
}

最简单的方法是将文件 app/Facades/GeoLocation.php' 的命名空间更改为 App\Facades;

然后将别名注册更新为

'GeoLocation' => 'App\Facades\GeoLocation',
