使用Laravel、Ajax和jQuery的"Like“系统

<button id="like-btn">Like</button>
<span id="like-count">0</span>

<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
<script>
$(document).ready(function() {
    $('#like-btn').click(function() {
        $.ajax({
            url: '/like',
            method: 'POST',
            data: { post_id: 123 }, // 假设这是帖子的ID
            success: function(response) {
                $('#like-count').text(response.like_count);
            }
        });
    });
});
</script>

// routes/web.php
Route::post('/like', [LikeController::class, 'likePost']);

// app/Http/Controllers/LikeController.php
namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Models\Post;

class LikeController extends Controller
{
    public function likePost(Request $request)
    {
        $postId = $request->input('post_id');
        $post = Post::find($postId);

        // 假设有一个Like模型来处理"Like"关系
        $like = new Like();
        $like->user_id = auth()->id();
        $like->post_id = $postId;
        $like->save();

        return response()->json(['like_count' => $post->likes_count]);
    }
}
