使用多用户登录可能遇到Argument 1 passed to Illuminate\Auth\EloquentUserProvider::validateCredentia...的错误，那么，如何实现多用户登录呢？
首先，进入/config/auth.php
<?php
return [
/*
|--------------------------------------------------------------------------
| Authentication Defaults
|--------------------------------------------------------------------------
|
| This option controls the default authentication "guard" and password
| reset options for your application. You may change these defaults
| as required, but they're a perfect start for most applications.
|
*/
'defaults' => [
'guard' => 'web', //默认的Auth方式
'passwords' => 'users',
],
/*
|--------------------------------------------------------------------------
| Authentication Guards
|--------------------------------------------------------------------------
|
| Next, you may define every authentication guard for your application.
| Of course, a great default configuration has been defined for you
| here which uses session storage and the Eloquent user provider.
|
| All authentication drivers have a user provider. This defines how the
| users are actually retrieved out of your database or other storage
| mechanisms used by this application to persist your user's data.
|
| Supported: "session", "token"
|
*/
'guards' => [
'web' => [ //默认的Auth方式
'driver' => 'session',
'provider' => 'users', //提供者，在下面设置
],
'admin' => [
'driver' => 'session',
'provider' => 'admins',
],
'add' => [ //这里是要增加的登录方式名称
'driver' => 'session', //使用session来控制登录，登出
'provider' => 'add', //使用的提供者名称
],
],
/*
|--------------------------------------------------------------------------
| User Providers
|--------------------------------------------------------------------------
|
| All authentication drivers have a user provider. This defines how the
| users are actually retrieved out of your database or other storage
| mechanisms used by this application to persist your user's data.
|
| If you have multiple user tables or models you may configure multiple
| sources which represent each model / table. These sources may then
| be assigned to any extra authentication guards you have defined.
|
| Supported: "database", "eloquent"
|
*/
'providers' => [
'users' => [
'driver' => 'eloquent',
'model' => App\Daili::class,
],
'admins' =>[
'driver' => 'eloquent',
'model' => App\Admin::class,
],
'add' => [
'driver' => 'eloquent', //这里用database或者eloquent,建议使用eloquent
'table' => 'App\Add::class', //用database的话，用表名，用eloquent的话，用App\Add::class
],
],
/*
|--------------------------------------------------------------------------
| Resetting Passwords
|--------------------------------------------------------------------------
|
| Here you may set the options for resetting passwords including the view
| that is your password reset e-mail. You may also set the name of the
| table that maintains all of the reset tokens for your application.
|
| You may specify multiple password reset configurations if you have more
| than one user table or model in the application and you want to have
| separate password reset settings based on the specific user types.
|
| The expire time is the number of minutes that the reset token should be
| considered valid. This security feature keeps tokens short-lived so
| they have less time to be guessed. You may change this as needed.
|
*/
'passwords' => [
'users' => [
'provider' => 'users',
'email' => 'auth.emails.password',
'table' => 'password_resets',
'expire' => 60,
],
],
];
相对应的，我们使用php artisan make:model Add，来创建一个model
<?php
namespace App;
// use Illuminate\Database\Eloquent\Model; //注意这里要改变，因为我们用的是Auth的
use Illuminate\Foundation\Auth\User as Authenticatable;
class Daili extends Authenticatable //继承从Model改成 Auth这个
{
protected $table = 'adds'; //表名
protected $fillable = [
'name','mobile','password'
];
protected $hidden = [
'password'
];
}可以了，大功告成，以后使用Auth::guard("add")就可以使用我们新添加的角色验证了！
