php这个样式谁会做，不知道做

Question

1.修改member表，增加字段remember_token，字段类型为varchar 长度100，允许为空；修改post表，增加user_id字段，保存发布文章的用户的id。2.为member表创建对应的模型类注意：模型类的初始化设置3.为post表创建对应的模型类注意：模型类根据对应数据表的初始化设置4.通过post的模型类实现文章的添加功能注意：需要通过Auth类获取登录用户的id一并添加到数据库中。Auth::guard(‘blog’)->id()获取登录用户的id5.制作首页效果参考如下图：查询所有文章信息，将文章的标题和发布时间输出到页面

为了帮助您解决这个问题，我会分步骤地解释如何完成每个任务，并提供相应的代码示例。这里假设您正在使用 Laravel 框架。

首先确保您的环境已经安装了Laravel，如果没有，请按照官方文档进行安装：https://laravel.com/docs/8.x/installation

第一步：修改数据库

1. 使用Artisan命令行工具来迁移数据库结构。首先创建两个迁移文件，分别用于member和post表：

php artisan make:migration add_remember_token_to_members --table=members
php artisan make:migration add_user_id_to_posts --table=posts

打开这两个文件（通常位于database/migrations目录），然后分别编辑它们：

add_remember_token_to_members.php:

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class AddRememberTokenToMembers extends Migration
{
    public function up()
    {
        Schema::table('members', function (Blueprint $table) {
            $table->string('remember_token', 100)->nullable();
        });
    }

    public function down()
    {
        Schema::table('members', function (Blueprint $table) {
            $table->dropColumn('remember_token');
        });
    }
}

add_user_id_to_posts.php:

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class AddUserIdToPosts extends Migration
{
    public function up()
    {
        Schema::table('posts', function (Blueprint $table) {
            $table->unsignedBigInteger('user_id')->after('id')->nullable();
            $table->foreign('user_id')->references('id')->on('members');
        });
    }

    public function down()
    {
        Schema::table('posts', function (Blueprint $table) {
            $table->dropForeign(['user_id_foreign']);
            $table->dropColumn('user_id');
        });
    }
}

运行迁移：

php artisan migrate

第二步：创建模型

在app/Models目录下创建Member.php和Post.php模型文件，内容如下：

Member.php:

namespace App\Models;

use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;
use Illuminate\Database\Eloquent\Factories\HasFactory;

class Member extends Authenticatable
{
    use HasFactory, Notifiable;

    protected $fillable = [
        'name',
        'email',
        'password',
        // 其他字段...
    ];

    protected $hidden = [
        'password',
        'remember_token',
    ];

    public function posts()
    {
        return $this->hasMany(Post::class);
    }
}

Post.php:

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Post extends Model
{
    use HasFactory;

    protected $fillable = [
        'title',
        'content',
        // 其他字段...
    ];

    public function user()
    {
        return $this->belongsTo(Member::class);
    }
}

第三步：创建控制器

创建一个名为ArticleController.php的控制器文件，用于处理文章相关操作：

namespace App\Http\Controllers;

use App\Models\Post;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;

class ArticleController extends Controller
{
    public function index()
    {
        $posts = Post::all();

        return view('articles.index', ['posts' => $posts]);
    }

    public function store(Request $request)
    {
        $validatedData = $request->validate([
            'title' => 'required|string|max:255',
            'content' => 'required|string',
        ]);

        $post = new Post();
        $post->title = $validatedData['title'];
        $post->content = $validatedData['content'];
        $post->user_id = Auth::guard('blog')->id();
        $post->save();

        return redirect('/articles');
    }
}

第四步：创建视图

在resources/views/articles目录下创建index.blade.php，内容如下：

@extends('layouts.app')

@section('content')
    <h1>文章列表</h1>
    @foreach ($posts as $post)
        <div>
            <h2>{{ $post->title }}</h2>
            <p>创建时间：{{ $post->created_at->format('Y年m月d H:i:s') }}</p>
        </div>
    @endforeach
@endsection

第五步：定义路由

在routes/web.php文件中添加以下路由：

Route::get('/articles', [App\Http\Controllers\ArticleController::class, 'index'])->name('articles.index');
Route::post('/articles', [App\Http\Controllers\ArticleController::class, 'store'])->name('articles.store');

第六步：实现登录状态判断与退出功能

在resources/views/layouts/app.blade.php中添加导航栏部分，并使用Laravel Blade模板引擎的@auth和@guest语句判断用户登录状态：

<nav class="navbar navbar-expand-md navbar-light bg-white shadow-sm">
    <div class="container">
        <!-- Brand -->
        <a class="navbar-brand" href="{{ url('/') }}">
            {{ config('app.name', 'Laravel') }}
        </a>

        <!-- Toggler/collapsibe button -->
        <button @click="toggleNavbar" class="navbar-toggler" type="button" data-bs-toggle="collapse"
                data-bs-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false"
                aria-label="Toggle navigation">
            <span class="navbar-toggler-icon"></span>
        </button>

        <!-- Navbar links -->
        <div class="collapse navbar-collapse" id="navbarSupportedContent">
            <!-- Left Side Links -->
            <ul class="navbar-nav me-auto mb-2 mb-lg-0">
                <li class="nav-item">
                    <a class="nav-link active" aria-current="page" href="#">首页</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="#">添加文章</a>
                </li>
            </ul>

            <!-- Right Side Links -->
            @auth('blog')
                <ul class="navbar-nav ms-auto mb-2 mb-lg-0">
                    <li class="nav-item dropdown">
                        <a href="#" class="nav-link dropdown-toggle" id="navbarDropdownMenuLink" role="button"
                           data-bs-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
                            {{ auth('blog')->user()->nickname ?? '匿名' }}
                        </a>
                        <ul class="dropdown-menu dropdown-menu-end" aria-labelledby="navbarDropdownMenuLink">
                            <li><a class="dropdown-item" href="#">个人中心</a></li>
                            <li><hr class="dropdown-divider"></li>
                            <li><a class="dropdown-item" href="{{ route('logout', ['guard' => 'blog']) }}"
                                   onclick="event.preventDefault();
                                                   document.getElementById('logout-form').submit();">
                                    退出
                                </a>
                                <form id="logout-form" action="{{ route('logout', ['guard' => 'blog']) }}" method="POST"
                                      style="display: none;">
                                    @csrf
                                </form>
                            </li>
                        </ul>
                    </li>
                </ul>
            @else
                <ul class="navbar-nav ms-auto mb-2 mb-lg-0">
                    <li class="nav-item"><a class="nav-link" href="{{ route('login', ['guard' => 'blog']) }}">登录</a></li>
                    <li class="nav-item"><a class="nav-link" href="{{ route('register', ['guard' => 'blog']) }}">注册</a></li>
                </ul>
            @endauth
        </div>
    </div>
</nav>

第七步：创建登录和注册视图

在resources/views/auth目录下创建login.blade.php和register.blade.php，并根据需要配置表单和验证规则。

第八步：配置 guards

在config/auth.php文件中配置多租户 guards，例如：

'guards' => [
    'web' => [
        'driver' => 'session',
        'provider' => 'users',
    ],

    'api' => [
        'driver' => 'token',
        'provider' => 'users',
    ],

    'blog' => [
        'driver' => 'session',
        'provider' => 'blog-users',
    ],
],

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

    'blog-users' => [
        'driver' => 'eloquent',
        'model' => App\Models\Member::class,
    ],
],

这样就完成了所有的要求。记得运行以下命令来清除缓存和重新生成路由：

php artisan cache:clear
php artisan route:cache

现在你应该可以在本地服务器上访问http://127.0.0.1:8000/articles查看文章列表，并且根据登录状态展示不同的导航栏。
