Laravel 5.7身份验证错误凭据与记录不匹配

Question

所以我在Laravel 5.7中做这个uni项目，我想添加身份验证，我使用这个命令安装了预制的Laravel身份验证解决方案

php artisan make:auth

但我注意到它使用电子邮件而不是用户名，在我的项目环境中，电子邮件甚至不是用户的属性之一，所以我做了一些关于如何使用用户名进行身份验证而不是电子邮件的研究我在youtube上关注了一个视频教程但是我没有为我工作，即使我做了完全相同的步骤。这是我的用户表结构：（id，username，password，telephone，usertype，remember_token，created_at，updated_at）

这是我的login.blade.php文件：

@extends('layouts.app')

@section('content')
<div class="container">
    <div class="row justify-content-center">
        <div class="col-md-8">
            <div class="card">
                <div class="card-header">{{ __('Login') }}</div>

                <div class="card-body">
                    <form method="POST" action="{{ route('login') }}">
                        @csrf

                        <div class="form-group row">
                            <label for="username" class="col-md-4 col-form-label text-md-right">{{ __('Pseudo Utilisateur') }}</label>

                            <div class="col-md-6">
                                <input id="username" type="text" class="form-control{{ $errors->has('username') ? ' is-invalid' : '' }}" name="username" value="{{ old('username') }}" required autofocus>

                                @if ($errors->has('username'))

                                @endif

这是user.php

<?php

namespace App;

use Illuminate\Notifications\Notifiable;
use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Foundation\Auth\User as Authenticatable;

class User extends Authenticatable
{
    use Notifiable;

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'username', 'password', 'telephone', 'usertype'
    ];

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password', 'remember_token',
    ];
}

这是LoginController

<?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');
    }

    public function username(){

      return 'username';
    }
}

我通过phpmyadmin添加了一个用户并尝试登录但我收到一个错误：“这些凭据与我们的记录不符。”

提前致谢。

Answer 1

您需要更改Illuminate \ Foundation \ Auth \ AuthenticatesUsers上的用户名值将电子邮件更改为用户名。

public function username()
    {
        return 'email'; //change this to username
    }

Answer 2

首先写“php artisan migrate：fresh”并编写上面的代码最后写“php artisan migrate”

class AppServiceProvider extends ServiceProvider
 {
/**
 * Bootstrap any application services.
 *
 * @return void
 */
public function boot()
{
    Schema::defaultStringLength(150); //database has storage of 150 and is extended to 150;
}
/**
 * Register any application services.
 *
 * @return void
 */
public function register()
{
    //
}
}
