Dalam era Internet, video telah menjadi cara penting untuk orang ramai memperoleh maklumat, mempelajari ilmu dan hiburan. Oleh itu, membina platform video dalam talian telah menjadi keperluan bagi banyak pembangun. Artikel ini akan memperkenalkan cara menggunakan rangka kerja Laravel untuk membangunkan platform video dalam talian dan menyediakan contoh kod khusus.
Sebelum memulakan pembangunan, kita perlu menjelaskan keperluan kita terlebih dahulu. Platform video dalam talian asas perlu mempunyai fungsi berikut:
composer create-project --prefer-dist laravel/laravel videoplatform
php artisan make:migration create_users_table php artisan make:migration create_videos_table php artisan make:migration create_categories_table php artisan make:migration create_comments_table
php artisan migrate
#🎜🎜 🎜🎜 #Dalam Laravel, penghalaan mengawal cara URL harus bertindak balas. Edit fail route/web.php dan reka laluan:
Route::get('/', 'HomeController@index')->name('home'); Route::get('/videos', 'VideoController@index')->name('videos.index'); Route::get('/videos/create', 'VideoController@create')->name('videos.create'); Route::post('/videos/store', 'VideoController@store')->name('videos.store'); Route::get('/videos/{id}', 'VideoController@show')->name('videos.show'); Route::get('/videos/{id}/edit', 'VideoController@edit')->name('videos.edit'); Route::put('/videos/{id}', 'VideoController@update')->name('videos.update'); Route::delete('/videos/{id}', 'VideoController@destroy')->name('videos.destroy'); Route::post('/comments', 'CommentController@store')->name('comments.store');
Paparan kod
class Video extends Model { // 添加分类关联关系 public function category() { return $this->belongsTo(Category::class); } // 添加评论关联关系 public function comments() { return $this->hasMany(Comment::class); } // 定义缩略图访问器 public function getThumbnailAttribute() { return Storage::url($this->attributes['thumbnail']); } }
class VideoController extends Controller { // 显示视频上传页面 public function create() { $categories = Category::all(); return view('videos.create', compact('categories')); } // 处理视频上传请求 public function store(Request $request) { $request->validate([ 'title' => 'required|max:255', 'description' => 'nullable|max:1000', 'category_id' => 'required|numeric', 'video_file' => 'required|mimetypes:video/mp4|max:102400', 'thumbnail_file' => 'required|mimetypes:image/jpeg,image/png|max:1024', ]); $video = new Video(); $video->title = $request->get('title'); $video->description = $request->get('description'); $video->category_id = $request->get('category_id'); $video->user_id = Auth::id(); $video_file = $request->file('video_file'); $video_file_name = uniqid().'.'.$video_file->getClientOriginalExtension(); Storage::putFileAs('public/videos', $video_file, $video_file_name); $video->video_file = 'storage/videos/'.$video_file_name; $thumbnail_file = $request->file('thumbnail_file'); $thumbnail_file_name = uniqid().'.'.$thumbnail_file->getClientOriginalExtension(); Storage::putFileAs('public/videos/thumbnails', $thumbnail_file, $thumbnail_file_name); $video->thumbnail = 'storage/videos/thumbnails/'.$thumbnail_file_name; $video->save(); return redirect()->route('videos.index'); } }
class CommentController extends Controller { public function store(Request $request) { $request->validate([ 'video_id' => 'required|numeric', 'content' => 'required|max:1000', ]); $comment = new Comment(); $comment->video_id = $request->get('video_id'); $comment->user_id = Auth::id(); $comment->content = $request->get('content'); $comment->save(); return redirect()->back(); } }
