如何在Laravel 5.2中使用不同的數據庫表列名進行登錄？

Question

我必須在Laravel 5.2中實現登錄功能。 我使用Laravel官方文檔成功完成了這項工作，但我不知道如何使用不同的數據庫表列名稱（即st_username和st_password對用戶進行身份驗證。

我在互聯網上尋找線索，但無濟於事。 我不知道我需要使用哪個類（比如，使用Illuminate .......）來驗證。 如果有人知道答案，請告訴我。

這是我的代碼：

登錄視圖

@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>

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

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

我搜索了很多如何自定義Laravel 5.2授權表格，這對我來說是100％的工作。 這是從下到上的解決方案。

此解決方案最初來自此處： https ： //laracasts.com/discuss/channels/laravel/replacing-the-laravel-authentication-with-a-custom-authentication

但我不得不做一些改變才能讓它發揮作用。

我的網絡應用程序適用於DJ，因此我的自定義列名稱為'dj_'，例如name為dj_name

1. 配置/ auth.php

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

2. 在config / app.php中將您的自定義提供程序添加到列表中...

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

3. 在文件夾app \\ Providers中創建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() { // } } 

4. 在文件夾app \\ Providers中創建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; } } 

5. 在App / Http / Controllers / Auth / AuthController.php中將所有'name'更改為'dj_name'並添加自定義字段（如果有）...您還可以將'email'更改為您的電子郵件列名稱

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

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

7. 在App / User.php中，將“name”更改為“dj_name”並添加自定義字段。 將“密碼”列更改為自定義列名添加

    public function getAuthPassword(){ return $this->custom_password_column_name; } 

8. 現在后端已經全部完成，所以你只需要更改布局login.blade.php，register.blade.php，app.blade.php ...這里你只需要將'name'改為'dj_name'，電子郵件，或者你的自定義字段...... !!! 密碼字段需要保留命名密碼!!!

此外，要進行唯一的電子郵件驗證，請更改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，如果要使自定義created_at，updated_at字段更改Illuminate \\ Database \\ Eloquent \\ Model.php中的全局變量

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

Answer 2

這很簡單，只需在Auth :: attempt（）/方法中使用所需的列名，如下所示：

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

更新：如果您還希望更改默認users默認身份驗證表，或者默認情況下更改型號名稱或路徑App\\User ，您可以在config\\auth.php找到這些設置

/*
|--------------------------------------------------------------------------
| 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 3

通過在auth.php中更改模型，自定義Auth :: attempt（）對我不起作用：

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

如果我嘗試通過Auth :: attempt中的自定義列名稱驗證Person：

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

我犯了同樣的錯誤：

EloquentUserProvider.php第112行中的ErrorException：未定義的索引：密碼

但我可以像這樣驗證一個人：

$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('/');
    }
}

但我認為那不是應該的樣子。

在提到的文件（EloquentUserProvider.php）中，我看到'密碼'是硬編碼的。

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());
}

所以實際上沒有辦法使用自定義列名稱來輕松實現密碼？
