一、dialog_id

message 表添加 dialog_id

 php artisan make:migration add_dialog_id_to_messages --table=messages

修改database/migrations/add_dialog_id_to_messages.php

public function up()
{
    Schema::table('messages', function (Blueprint $table) {
        $table->bigInteger('dialog_id')->default(0);
    });
}

public function down()
{
    Schema::table('messages', function (Blueprint $table) {
        $table->dropColumn(['dialog_id']);
    });
}

执行数据迁移

php artisan migrate

修改 app/Message.php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Message extends Model
{
    protected $table = 'messages';

    protected $fillable = ['from_user_id','to_user_id','content','dialog_id'];

    public function fromUser()
    {
        return $this->belongsTo(User::class,'from_user_id');
    }

    public function toUser()
    {
        return $this->belongsTo(User::class,'to_user_id');
    }
}

修改 app/Http/Controllers/MessagesController.php

public function store()
{
    $message = $this->messageRepository->create([
        'to_user_id' => request('user'),
        'from_user_id' => user('api')->id,
        'content' => request('content'),
        'dialog_id' => time().Auth::id(),
    ]);
    if($message){
        $status = true;
    }else{
        $status = false;
    }
    return response()->json(['status'=>$status]);
}

二、创建控制器

创建收件箱控制器

php artisan make:controller InboxController

修改 routes/web.php

Route::get('inbox', 'InboxController@index');
Route::get('inbox/{dialogId}', 'InboxController@show');
Route::post('inbox/{dialogId}/store', 'InboxController@store');

修改 app/Repositories/MessageRepository.php

namespace App\Repositories;

use App\Message;

class MessageRepository
{
    public function create(array $attributes)
    {
        return Message::create($attributes);
    }

    public function getMessageList()
    {
        return Message::where('to_user_id',user()->id)
            ->orWhere('from_user_id',user()->id)
            ->with(['fromUser','toUser'])
            ->get()
            ->unique('dialog_id')
            ->groupBy('to_user_id');
    }

    public function getMessageListByDialogId($dialogId)
    {
        return Message::where('dialog_id', $dialogId)->latest()->get();
    }

    public function store($dialogId)
    {
        $message = Message::where('dialog_id', $dialogId)->first();
        $toUserId = $message->from_user_id === user()->id ? $message->to_user_id : $message->from_user_id;
        return Message::create([
            'from_user_id' => user()->id,
            'to_user_id' => $toUserId,
            'content' => request('content'),
            'dialog_id' => $dialogId
        ]);
    }
}

修改 app/Http/Controllers/InboxController.php

namespace App\Http\Controllers;

use App\Repositories\MessageRepository;

class InboxController extends Controller
{
    protected $messageRepository;

    public function __construct(MessageRepository $messageRepository)
    {
        $this->messageRepository = $messageRepository;
        $this->middleware('auth');
    }

    public function index()
    {
        $messages = $this->messageRepository->getMessageList();
        return view('inbox.index', compact('messages'));
    }

    public function show($dialogId)
    {
        $messages = $this->messageRepository->getMessageListByDialogId($dialogId);
        return view('inbox.show', compact('messages','dialogId'));
    }

    public function store($dialogId)
    {
        $this->messageRepository->store($dialogId);
        return back();
    }
}

三、创建视图

修改 resources/assets/css/style.css

.message-list {
    margin-top: 80px;
}

.a-avatar {
    width: 75px;
    display: block
}

.avatar {
    border-radius: 50%;
}

执行 gulp

gulp

新建 resources/views/inbox/index.blade.php

新建 resources/views/inbox/show.blade.php

访问：http://127.0.0.1:8000/inbox 进行测试
