我必须在Laravel 5.2中实现登录功能。我使用官方的Laravel文档成功完成了这项工作，但我不知道如何使用不同的数据库表列名称来验证用户，即st_usernameand st_password。
我在互联网上寻找线索，但无济于事。我不知道我需要使用哪个类（比如，使用Illuminate .......）来验证。如果有人知道答案，请告诉我。
这是我的代码：
登录视图
@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>

我搜索了很多如何自定义Laravel 5.2授权表格，这对我来说是100％的工作。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
但我不得不做一些改变才能让它发挥作用。
我的网络应用程序适用于DJ，因此我的自定义列名称为'dj_'，例如name为dj_name
// change this
'driver' => 'eloquent',
// to this
'driver' => 'custom',
'providers' => [
...
// add this on bottom of other providers
App\Providers\CustomAuthProvider::class,
...
],
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()
{
//
}
}

// TODO: Implement retrieveById() method.

{
// 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;
}
}
protected $table = 'djs';
protected $primaryKey = 'dj_id';
public function getAuthPassword(){
return $this->custom_password_column_name;
}
此外，要进行唯一的电子邮件验证，请更改AuthController.php
'custom_email_field' => 'required|email|max:255|unique:users',
to
'custom_email_field' => 'required|email|max:255|unique:custom_table_name',
此外，如果要使自定义created_at，updated_at字段更改Illuminate \ Database \ Eloquent \ Model.php中的全局变量
const CREATED_AT = 'dj_created_at';
const UPDATED_AT = 'dj_updated_at';
这很简单，只需在Auth :: attempt（）/方法中使用所需的列名，如下所示：
if (Auth::attempt(['st_username' =>$username,'st_password' => $password])) {
// Authentication passed...
return redirect()>intended('dashboard');
}
更新：如果您还希望默认更改默认认证表users或默认更改模型名称或路径App\User，您可以在config\auth.php中找到这些设置
/*
|--------------------------------------------------------------------------
| 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,
通过在auth.php中更改模型，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中的自定义列名称验证Person：
if (Auth::attempt(['persUsername' => $request->user, 'persPassword' => $request->pass])) {
return redirect()->intended('/');
}
我犯了同样的错误：
EloquentUserProvider.php第112行中的ErrorException：未定义的索引：密码
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('/');
}
}
但我认为那不是应该的样子。
在提到的文件（EloquentUserProvider.php）中，我看到'密码'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称来轻松实现密码？
