我正在使用自动生成的身份验证设置进行登录和注册等。我已经使注册工作，但无法使登录工作。
默认情况下，当我运行它时，我收到此错误
SQLSTATE[42S22]: Column not found: 1054 Unknown column 'email' in 'where clause' (SQL: select * from `consumers` where `email` = jermayne21@gmail.com limit 1)
这是可以理解的，我的数据库中的电子邮件列是con_email，我的密码列是con_password
我更新了LoginController.php，将email和password属性更改为上述列。
LoginController.php
<?php
namespace App\Http\Controllers\Auth;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use Illuminate\Foundation\Auth\AuthenticatesUsers;
use App\User;
class LoginController extends Controller
{
use AuthenticatesUsers;
/**
* Where to redirect users after login.
*
* @var string
*/
protected $redirectTo = '/home';
/**
* Create a new controller instance.
*
* @return void
*/
public function __construct()
{
$this->middleware('guest')->except('logout');
}
public function username()
{
return 'con_email';
}
public function getAuthPassword()
{
return $this->con_password;
}
}
User.php（供参考）
<?php
namespace App;
use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;
class User extends Authenticatable
{
use Notifiable;
protected $table = 'consumers';
protected $primaryKey = 'con_id';
/**
* The attributes that are mass assignable.
*
* @var array
*/
protected $fillable = [ 'con_id', 'con_fname', 'con_lname', 'con_email', 'con_password', 'total_earned'];
/**
* The attributes that should be hidden for arrays.
*
* @var array
*/
protected $hidden = [
'con_password', 'remember_token',
];
}

从默认代码进行更改后，我不再收到错误消息。当我登录时只是重新加载到登录屏幕而没有任何验证错误（但好像它几乎是一个错误的信息但是它不是错误的登录信息。
有关我发现的类似问题的其他答案的问题
我没有AuthController.php，但我已经阅读了许多答案，声明要在该文件中覆盖它。当我运行php artisan make:auth时，它会自动生成LoginController.php，ForgotPasswordController.php，RegisterController.php和ResetPasswordController.php这是laravel 5.5中的最新更新（或者可能是在5.2中完成的）我读的是什么）我在所有控制器中得到了相同的当前错误，所以我想可能AuthController.php被更改为上面的4个独立控制器。
答案 0 :(得分：2)
for laravel5.5
app / Http / Controllers / Auth / LoginController.php - 添加了函数username()
<?php
namespace App\Http\Controllers\Auth;
use App\Http\Controllers\Controller;
use Illuminate\Foundation\Auth\AuthenticatesUsers;
class LoginController extends Controller
{
/*
|--------------------------------------------------------------------------
| Login Controller
|--------------------------------------------------------------------------
|
| This controller handles authenticating users for the application and
| redirecting them to your home screen. The controller uses a trait
| to conveniently provide its functionality to your applications.

*/
use AuthenticatesUsers;
/**
* Where to redirect users after login.
*
* @var string
*/
protected $redirectTo = '/home';
/**
* Create a new controller instance.
*
* @return void
*/
public function __construct()
{
$this->middleware('guest')->except('logout');
}
/**
* Get the login username to be used by the controller.
*
* @return string
*/
public function username()
{
return 'con_email';
}
}
模型app / User.php - 添加了函数getAuthPassword（）
<?php
namespace App;
use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;
class User extends Authenticatable
{
use Notifiable;
/**
* The attributes that are mass assignable.
*
* @var array
*/
protected $fillable = [
'name', 'con_email', 'con_password',
];
/**
* The attributes that should be hidden for arrays.
*
* @var array
*/
protected $hidden = [
'con_password', 'remember_token',
];
/**
* Get the password for the user.
*
* @return string
*/
public function getAuthPassword()
{
return $this->attributes['con_password'];
}
}

您必须覆盖postLogin()
Auth/AuthController.php功能
/**
* Handle a login request to the application.
*
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
*/
public function postLogin(Request $request)
{
$this->validate($request, [
'email' => 'required|email', 'password' => 'required',
]);
$credentials['con_email'] = $request->input('email');
$credentials['con_password'] = $request->input('password');
if ($this->auth->attempt($credentials, $request->has('remember')))
{
return redirect()->intended($this->redirectPath());
}
return redirect($this->loginPath())
->withInput($request->only('email', 'remember'))
->withErrors([
'email' => $this->getFailedLoginMessage(),
]);
}
