未找到 Laravel Passport 安装类

Question

我正在尝试将我的 Laravel 应用程序配置为使用 Passport，但在我的 AppServiceProvider.php 中加载类时遇到了困难。这是我所做的......

<?php // AuthServiceProvider.php

namespace S1\Providers;

use Laravel\Passport\PassportServiceProvider;
use Illuminate\Support\Facades\Gate;
use Illuminate\Foundation\Support\Providers\AuthServiceProvider as 
ServiceProvider;

class AuthServiceProvider extends ServiceProvider
{
...
    public function boot()
    {
        $this->registerPolicies();
        Passport::routes();
        Passport::tokensCan([
            'client' => 'this is a api client test'
        ]);
    }
}

.

<?php .  // auth.php
 ...
return [

    'guards' => [
        'web' => [
             'driver' => 'passport',
            'provider' => 'users',
        ],
], ...

.

<?php // app.php

'providers' => [
...
Laravel\Passport\PassportServiceProvider::class,
....

.

<?php  // AppServiceProvider.php

namespace S1\Providers;

use Illuminate\Support\ServiceProvider;
use S1\Providers\AppServiceProvider;
use Laravel\Passport\PassportServiceProvider;

class AppServiceProvider extends ServiceProvider
{

    public function register()
    {
        // Enable Laravel Migrations Generator for development only
        if ($this->app->environment() !== 'production') {
            $this->app->register(\Way\Generators\GeneratorsServiceProvider::class);
            $this->app->register(\Xethron\MigrationsGenerator\MigrationsGeneratorServiceProvider::class);
        }
    }
}

这样做的结果是出现以下错误：

  [Symfony\Component\Debug\Exception\FatalThrowableError]  
  Class 'S1\Providers\Passport' not found   

我确实有这个工作，但不得不重新构建，现在我无法克服这个错误。我的命名空间出了点问题，但我不知道是什么。

Answer 1

在您的AuthServiceProvider.php 中，更改：

use Laravel\Passport\PassportServiceProvider;

到：

use Laravel\Passport\Passport;

Answer 2

好像忘记导入护照了，试试添加这个

use App\Passport\Passport;

到您的 AppServiceProvider

<?php  // AppServiceProvider.php

namespace S1\Providers;

use App\Passport\Passport;

use Illuminate\Support\ServiceProvider;
use S1\Providers\AppServiceProvider;
use Laravel\Passport\PassportServiceProvider;

class AppServiceProvider extends ServiceProvider
{

    public function register()
    {
        // Enable Laravel Migrations Generator for development only
        if ($this->app->environment() !== 'production') {
            $this->app->register(\Way\Generators\GeneratorsServiceProvider::class);
            $this->app->register(\Xethron\MigrationsGenerator\MigrationsGeneratorServiceProvider::class);
        }
    }
}

Answer 3

请检查您的 composer.json，laravel/passport 是否将其包含在“require”中，如下所示：

"require": {
        "php": ">=5.6.4",
        "laravel/framework": "5.4.*",
        "laravel/passport": "^3.0",
        "laravel/tinker": "~1.0"
 },

如果不重新运行

作曲家需要 laravel/passport

Answer 4

为您的特定Laravel 版本安装正确的Passport 版本。假设你有 Laravel 5.5，安装 Passport 4.0：

composer require laravel/passport=~4.0

检查你的 Laravel 版本：

php artisan --version

或者查看composer.json中require对象下的"laravel/framework": "5.5.*",。

<?php

namespace App\Providers;

use Laravel\Passport\Passport;

use Illuminate\Support\Facades\Gate;
use Laravel\Passport\PassportServiceProvider;
use Illuminate\Foundation\Support\Providers\AuthServiceProvider as ServiceProvider;

class AuthServiceProvider extends ServiceProvider
{
    /**
     * The policy mappings for the application.
     *
     * @var array
     */
    protected $policies = [
        'App\Model' => 'App\Policies\ModelPolicy',
    ];

    /**
     * Register any authentication / authorization services.
     *
     * @return void
     */
    public function boot()
    {
        $this->registerPolicies();

        Passport::routes();

        //
    }
}
