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，在我的项目的上下文中，电子邮件甚至不是用户的属性之一，所以我对如何使用用户名而不是电子邮件，我跟着 youtube 上的视频教程，但我没有为我工作，即使我做了完全相同的步骤。这是我的用户表结构：（id、用户名、密码、电话、用户类型、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'))
                                    <span class="invalid-feedback" role="alert">

                                    </span>
                                @endif
                            </div>
                        </div>

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',
    ];
}

这是登录控制器

<?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，但出现错误：“这些凭据与我们的记录不匹配。”

提前致谢。

Answer 1

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()
{
    //
}
}

Answer 2

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
    }
