自定义登录

如果不使用laravel-admin内置的认证登录逻辑,可以参考下面的方式自定义登录认证逻辑

首先要先定义一个user provider,用来获取用户身份, 比如app/Providers/CustomUserProvider.php

<?php

namespace App\Providers;

use Illuminate\Contracts\Auth\Authenticatable;
use Illuminate\Contracts\Auth\UserProvider;

class CustomUserProvider implements UserProvider
{
    public function retrieveById($identifier)
    {}

    public function retrieveByToken($identifier, $token)
    {}

    public function updateRememberToken(Authenticatable $user, $token)
    {}

    public function retrieveByCredentials(array $credentials)
    {
        // 用$credentials里面的用户名密码去获取用户信息,然后返回Illuminate\Contracts\Auth\Authenticatable对象
    }

    public function validateCredentials(Authenticatable $user, array $credentials)
    {
        // 用$credentials里面的用户名密码校验用户,返回true或false
    }
}

在方法retrieveByCredentialsvalidateCredentials中, 传入的$credentials就是登录页面提交的用户名和密码数组,然后你可以使用$credentials去实现自己的登录逻辑

Interface Illuminate\Contracts\Auth\Authenticatable的定义如下:

<?php

namespace Illuminate\Contracts\Auth;

interface Authenticatable {

    public function getAuthIdentifierName();
    public function getAuthIdentifier();
    public function getAuthPassword();
    public function getRememberToken();
    public function setRememberToken($value);
    public function getRememberTokenName();

}

上面interface每个方法的解释参考adding-custom-user-providers

定义好了User provider之后,打开app/Providers/AuthServiceProvider.php注册它:

<?php

namespace App\Providers;

use Illuminate\Support\Facades\Auth;
use Illuminate\Foundation\Support\Providers\AuthServiceProvider as ServiceProvider;

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

        Auth::provider('custom', function ($app, array $config) {

            // Return an instance of Illuminate\Contracts\Auth\UserProvider...
            return new CustomUserProvider();
        });
    }
}

最后修改一下配置,打开config/admin.php,找到auth部分修改:

    'auth' => [
        'guards' => [
            'admin' => [
                'driver' => 'session',
                'provider' => 'admin',
            ]
        ],

        // 修改下面
        'providers' => [
            'admin' => [
                'driver' => 'custom',
            ]
        ],
    ],

这样就完成了自定义登录认证的逻辑,自定义登录算是laravel中比较复杂的部分,需要开发者有耐心的一步步调试完成。
