我已升级到相对平稳的laravel 5.5。
但是我的图像功能现在出现错误。我不知道为什么
这是它在前端上的用法：http://website.com/media/1000x300/5/filename.jpg

但是我真的需要那个功能。我不知道自己在做什么错或需要更改什么？这就是我得到的错误

答案 0 :(得分：0)
您应该知道，在本地主机Laravel中使用public文件夹，并且在服务器内部（例如主机laravel）无法使用该文件夹，而laravel未知的服务器，您必须在config.php中定义上传文件夹，例如：
'public_path' => 'C:\xampp\htdocs\YOUR_WEB_APP\public', //in localhost
'public_path' => '/home/YOUR_WEB_APP/public_html', //in host
然后使用该图像并上传图像，将其调整为文件夹大小：
public function uploadImage($file, $filename)
{
$year = Carbon::now()->year;
$imagePath = "/uploads/post_images/" . $year . "/";
$public_html = config('app.public_path');
$data = $file->move($public_html . $imagePath, $filename);
$sizes = ['300', '600', '900'];
$url['images'] = $this->resize($data->getRealPath(), $sizes, $imagePath, $filename);
$url['thumbnail'] = $url['images'][$sizes[0]];
return $url;
}
