如何使用 Laravel 5.2 中的不同数据库 table 列名登录？

Question

我必须在 Laravel 5.2 中实现登录功能。我已经使用官方 Laravel 文档成功地做到了这一点，除了我不知道如何使用不同的数据库 table 列名称（即 st_username 和 st_password 来验证用户。

我已经在互联网上搜索了线索，但无济于事。我不知道我需要为 Auth 使用哪个 class（比如，使用 Illuminate......）。如果有人知道答案，请告诉我。

这是我的代码：

登录查看

@extends('layouts.app')
@section('content')

<div class="contact-bg2">
    <div class="container">
        <div class="booking">
            <h3>Login</h3>
            <div class="col-md-4 booking-form" style="margin: 0 33%;">
                <form method="post" action="{{ url('/login') }}">
                    {!! csrf_field() !!}

                    <h5>USERNAME</h5>
                    <input type="text" name="username" value="abcuser">
                    <h5>PASSWORD</h5>
                    <input type="password" name="password" value="abcpass">

                    <input type="submit" value="Login">
                    <input type="reset" value="Reset">
                </form>
            </div>
        </div>
    </div>

</div>
<div></div>

                    'email' => 'required|email|max:255|unique:users',
                    'password' => 'required|confirmed|min:6',
        ]);
    }

路由文件

Route::get('/', function () {
    return view('index');
});

Route::group(['middleware' => 'web'], function () {
    Route::auth();

    Route::get('/home', 'HomeController@index');
});

            'expire' => 60,
        ],
    ],
];

Answer 1

这很简单，只需在 Auth::attempt()/方法中使用所需的列名称，如下所示：

if (Auth::attempt(['st_username' =>$username,'st_password' => $password])) { 
    // Authentication passed... 
    return redirect()>intended('dashboard'); 
}

已更新： 如果您还希望更改默认身份验证 table 默认情况下为 users 或更改模型名称或默认路径 App\User，您可以在 config\auth.php

/*
|--------------------------------------------------------------------------
| Authentication Table
|--------------------------------------------------------------------------
|
| When using the "Database" authentication driver, we need to know which
| table should be used to retrieve your users. We have chosen a basic
| default value but you may easily change it to any table you like.
|
*/

//'table' => 'users', 
'table' => 'new_tables_for_authentication',



/*
|--------------------------------------------------------------------------
| Authentication Model
|--------------------------------------------------------------------------
|
| When using the "Eloquent" authentication driver, we need to know which
| Eloquent model should be used to retrieve your users. Of course, it
| is often just the "User" model but you may use whatever you like.
|
*/

//'model' => App\User::class,
'model' => App\Models\User::class,

Answer 2

我搜索了很多如何自定义 Laravel 5.2 授权表格，这对我 100% 有用。这是从下到上的解决方案。

这个解决方案最初来自这里：https://laracasts.com/discuss/channels/laravel/replacing-the-laravel-authentication-with-a-custom-authentication

但我必须进行一些更改才能使其正常工作。

我的网络应用程序是为 DJ 设计的，所以我的自定义列名称带有 'dj_'，例如名称是 dj_name

config/auth.php

// change this
'driver' => 'eloquent',
// to this
'driver' => 'custom',

在 config/app.php 中将您的自定义提供程序添加到列表中 ...

'providers' => [
    ...
    // add this on bottom of other providers
    App\Providers\CustomAuthProvider::class,
    ...
],

在文件夹 app\Providers 中创建 CustomAuthProvider.php

namespace App\Providers;

use Illuminate\Support\Facades\Auth;

use App\Providers\CustomUserProvider;
use Illuminate\Support\ServiceProvider;

class CustomAuthProvider extends ServiceProvider {

    /**
     * Bootstrap the application services.
     *
     * @return void
     */
    public function boot()
    {
        Auth::provider('custom', function($app, array $config) {
       // Return an instance of             Illuminate\Contracts\Auth\UserProvider...
        return new CustomUserProvider($app['custom.connection']);
        });
    }

    /**
     * Register the application services.
     *
     * @return void
     */
    public function register()
    {
        //
    }
}

也在文件夹 app\Providers

中创建 CustomUserProvider.php

<?php

namespace App\Providers;
use App\User; use Carbon\Carbon;
use Illuminate\Auth\GenericUser;
use Illuminate\Contracts\Auth\Authenticatable;
use Illuminate\Contracts\Auth\UserProvider;
use Illuminate\Support\Facades\Hash;
use Illuminate\Support\Facades\Log;

class CustomUserProvider implements UserProvider {

/**
 * Retrieve a user by their unique identifier.
 *
 * @param  mixed $identifier
 * @return \Illuminate\Contracts\Auth\Authenticatable|null
 */
public function retrieveById($identifier)
{
    // TODO: Implement retrieveById() method.


    $qry = User::where('dj_id','=',$identifier);

    if($qry->count() >0)
    {
        $user = $qry->select('dj_id', 'dj_name', 'first_name', 'last_name', 'email', 'password')->first();

        $attributes = array(
            'id' => $user->dj_id,
            'dj_name' => $user->dj_name,
            'password' => $user->password,
            'email' => $user->email,
            'name' => $user->first_name . ' ' . $user->last_name,
        );

        return $user;
    }
    return null;
}

/**
 * Retrieve a user by by their unique identifier and "remember me" token.
 *
 * @param  mixed $identifier
 * @param  string $token
 * @return \Illuminate\Contracts\Auth\Authenticatable|null
 */
public function retrieveByToken($identifier, $token)
{
    // TODO: Implement retrieveByToken() method.
    $qry = User::where('dj_id','=',$identifier)->where('remember_token','=',$token);

    if($qry->count() >0)
    {
        $user = $qry->select('dj_id', 'dj_name', 'first_name', 'last_name', 'email', 'password')->first();

        $attributes = array(
            'id' => $user->dj_id,
            'dj_name' => $user->dj_name,
            'password' => $user->password,
            'email' => $user->email,
            'name' => $user->first_name . ' ' . $user->last_name,
        );

        return $user;
    }
    return null;



}

/**
 * Update the "remember me" token for the given user in storage.
 *
 * @param  \Illuminate\Contracts\Auth\Authenticatable $user
 * @param  string $token
 * @return void
 */
public function updateRememberToken(Authenticatable $user, $token)
{
    // TODO: Implement updateRememberToken() method.
    $user->setRememberToken($token);

    $user->save();

}

/**
 * Retrieve a user by the given credentials.
 *
 * @param  array $credentials
 * @return \Illuminate\Contracts\Auth\Authenticatable|null
 */
public function retrieveByCredentials(array $credentials)
{

    // TODO: Implement retrieveByCredentials() method.
    $qry = User::where('email','=',$credentials['email']);

    if($qry->count() > 0)
    {
        $user = $qry->select('dj_id','dj_name','email','password')->first();


        return $user;
    }

    return null;


}

/**
 * Validate a user against the given credentials.
 *
 * @param  \Illuminate\Contracts\Auth\Authenticatable $user
 * @param  array $credentials
 * @return bool
 */
public function validateCredentials(Authenticatable $user, array $credentials)
{
    // TODO: Implement validateCredentials() method.
    // we'll assume if a user was retrieved, it's good

    // DIFFERENT THAN ORIGINAL ANSWER
    if($user->email == $credentials['email'] && Hash::check($credentials['password'], $user->getAuthPassword()))//$user->getAuthPassword() == md5($credentials['password'].\Config::get('constants.SALT')))
    {


        //$user->last_login_time = Carbon::now();
        $user->save();

        return true;
    }
    return false;


}
}

在App/Http/Controllers/Auth/AuthController.php全部改 'name' 到 'dj_name' 并添加自定义字段（如果有）...您还可以将 'email' 更改为您的电子邮件列名称

在Illuminate\Foundation\Auth\User.php中添加

protected $table = 'djs';
protected $primaryKey  = 'dj_id';

在 App/User.php 中将 'name' 更改为 'dj_name' 并添加您的自定义字段。要将 'password' 列更改为您的自定义列名称，请添加
```
public function getAuthPassword(){
    return $this->custom_password_column_name;
}
```
至此后台全部搞定，只需要更改布局login.blade.php、register.blade.php、app.blade.php...这里只需要更改'name' 到 'dj_name'、电子邮件或您的自定义字段... ！！！密码字段需要保留命名密码!!!

此外，要进行独特的电子邮件验证更改 AuthController.php

'custom_email_field' => 'required|email|max:255|unique:users',
to
'custom_email_field' => 'required|email|max:255|unique:custom_table_name',

此外，如果您想自定义 created_at 一个 updated_at 字段更改 Illuminate\Database\Eloquent\Model 中的全局变量。php

const CREATED_AT = 'dj_created_at';
const UPDATED_AT = 'dj_updated_at';

Answer 3

通过像这样更改 auth.php 中的模型，自定义 Auth::attempt() 对我不起作用：

'providers' => [
    'users' => [
        'driver' => 'eloquent',
        'model' => App\Person::class,
    ],
],

如果我尝试通过 Auth::attempt 中的自定义列名验证一个人：

if (Auth::attempt(['persUsername' => $request->user, 'persPassword' => $request->pass])) {
    return redirect()->intended('/');
}

我得到同样的错误：

ErrorException in EloquentUserProvider.php line 112: Undefined index: password

但我可以像这样验证一个人：

$person = Person
    ::where('persUsername', $request->user)
    ->where('persPassword', $request->pass)
    ->first();

if (! is_null($person)) {
    if ($person->persUsername === $request->user && $person->persPassword === $request->pass) {
        Auth::login($person, false);
        return redirect()->intended('/');
    }
}

但我想这不是应该的样子。

在提到的文件 (EloquentUserProvider.php) 中，我看到 'password' 是硬编码的。

public function retrieveByCredentials(array $credentials)
{
    $query = $this->createModel()->newQuery();

    foreach ($credentials as $key => $value) {
        if (! Str::contains($key, 'password')) {
            $query->where($key, $value);
        }
    }

    return $query->first();
}

public function validateCredentials(UserContract $user, array $credentials)
{
    $plain = $credentials['password'];

    return $this->hasher->check($plain, $user->getAuthPassword());
}

所以实际上没有办法使用自定义列名作为密码的简单方法吗？
