“无法将图像数据写入路径” - Laravel Image Intervention

Question

Can't write image data to path (Laravel)

I'm not able to save anything to the storage directory in a Laravel project and receive the following error:

I've spent the last three weeks trying to find out why I can't save images to the Storage folder in Laravel with no luck. I've scoured StackOverflow and have come to the conclusion that it's probably due to my Docker image. I'd love to use my custom images if possible but get them working. Here's my setup:

Dockerfile (base image)

Upload Image File (Laravel)

    public function updateProfilePic(Request $request)
    {
        $request->validate([
            'upload_profile_pic' => 'required|image|mimes:jpeg,jpg,png|max:2048',
        ]);
        $id = request()->get('id');

        $file = $request->file('upload_profile_pic');
        $img = Image::make($file)
            ->resize(320, 240)
            ->save(storage_path(), $file->getClientOriginalName());

        // Upload Profil Pic (IMAGE INTERVENTION - LARAVEL)
        //Image::make($request->file('upload_profile_pic'))->fit(150, 150)->save(storage_path('avatars/'.$id.'.png'));

        session()->flash("message", "Profile picture updated successfully.");
        return redirect()->back();
    }

@leo I apologize I never came back to answer this. I don't remember the exact fix but I believe I was misusing storage_path . Here is the corrected PHP code:

    public function uploadPostImage(Request $request)
    {
        $request->validate([
            'upload_image' => 'required|image|mimes:jpeg,jpg,png|max:2048',
        ]);
        $id = mt_rand(100000000000, 999999999999); # TODO: This is hacky, fix down the road

        if (!is_dir(storage_path("app/public/post-images"))) {
            mkdir(storage_path("app/public/post-images"), 0775, true);
        }

        // Upload Avatar (IMAGE INTERVENTION - LARAVEL)
        Image::make($request->file("upload_image"))->save(storage_path("app/public/post-images/".$id.".png"));

        session()->flash("message", "Image uploaded successfully.");
        return redirect()->back();
    }

I used the same Docker image and docker-compose file which means it must have been fixed by using storage_path correctly.
