Question

我正在努力用Laravel图像干预调整图像大小。我可以正常命名和保存图像，但是当我添加图像干预时，它不会将创建的新文件保存到文件夹中。

以下是我在控制器中的内容

 //This all works
        $title = str_slug(request('title'));
        $filenameWithExt = $request->file('cover_image')->getClientOriginalName();
        $filename = pathinfo($filenameWithExt, PATHINFO_FILENAME);
        $extension = $request->file('cover_image')->getClientOriginalExtension();
        $fileNameToStore= $title.'.'.$extension;
        $thumbnailpic= 'thumb'.'-'.$fileNameToStore;
//store image
        $path = $request->file('cover_image')->storeAs('public/cover_images', $fileNameToStore);

//Here is where I am trying to resize and it breaks

        $file = Input::file('cover_image');
        Image::make( $file->getRealPath() )->fit(340, 340)->save('public/cover_images/' . $thumbnailpic);

这是我得到的错误

"Can't write image data to path (public/cover_images/thumb-imagename.png)"

如果我删除两行调整大小代码，一切都很完美。我在本地运行它已经完全打开所有权限。不知道还能做什么。谢谢！

问题似乎与保存路径有关，你能试试这样的完整路径，

Traceback:

File "/usr/lib/python2.7/site-packages/django/core/handlers/base.py"
in get_response
 174.                     response =
self.process_exception_by_middleware(e, request)

 172.                     response = response.render()

 160.             self.content = self.rendered_content

rendered_content
 137.         content = template.render(context, self._request)
File "/usr/lib/python2.7/site-packages/django/template/backends/django.py"

 95.             return self.template.render(context)

File "/usr/lib64/python2.7/contextlib.py" in __enter__
 17.             return self.gen.next()

exceptions must be old-style classes or derived from BaseException, not str

Exception Location:
/usr/lib/python2.7/site-packages/django/utils/module_loading.py in
import_string, line 23

我希望这会有所帮助

所以我终于明白了。我保存到public_path，图像干预显然不喜欢。所以我使用下面的代码

    $source = storage_path().'/app/public/cover_images/'.$fileNameToStore;
    $target = storage_path().'/app/public/cover_images/' . $thumbnailpic;


    Image::make($source)->fit(140, 140)->save($target);

它有效！

使用Laravel图像干预调整图像大小不会让我保存
