如何在Laravel中查看我上传的pdf文件？

Hey guys need your help on this one. I find the file system of laravel 5.5 confusing I read the docs but I'm still confused, how do I retrieve and view the file that I uploaded? Here's my controller:

SoleDistcontroller.blade.php

public function store(Request $request)
    {
        //
        $Record=new SoleDist;
        $Record->name = $request->get('name');
        $Record->address = $request->get('address');
        $path = Storage::putFile('certificates',$request->file('certificate'));
        $Record->file_name = $path;
        $Record->save();
        return redirect()->back()->with('flash_message','Sole Distributor added successfully!');
    }

    /**
     * Display the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function show($id)
    {
        //
        $Record = SoleDist::find($id);
        $url = Storage::get($Record->file_name);
        return redirect($url);
    }
