Laravel多用户Auth登录

使用多用户登录可能遇到Argument 1 passed to IlluminateAuthEloquentUserProvider::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" => AppDaili::class,
        ],
        "admins" =>[
            "driver" => "eloquent",
            "model" => AppAdmin::class, 
        ],

         "add" => [
             "driver" => "eloquent", //这里用database或者eloquent,建议使用eloquent
             "table" => "AppAdd::class", //用database的话，用表名，用eloquent的话，用AppAdd::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 IlluminateDatabaseEloquentModel; //注意这里要改变，因为我们用的是Auth的
use IlluminateFoundationAuthUser 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！
