我试图保存上传的pdf文件，但pdf文件名在存储链接上更改。保存时有没有办法保留原来的文件名？

public $code, $pdfs;

public function mount(Applicant $applicant)
    {
        $this->code = substr(str_shuffle(str_repeat("ABCDEFGHIJKLMNOPQRSTUVWXYZ", 5)), 0, 3).Carbon::createFromFormat('Y-m-d H:i:s', now())->format('md').rand(100, 999);
    }

public function submit(Request $request)
    {
 
        $this->validate([
             'pdfs.*' => 'mimes:pdf',
          ]);

        $filenames = collect($this->tests)->map->store($this->code.'/', 'public');
        return redirect()->route('careers.vacant');
    }

这是我刀

<form wire:submit.prevent="submit" class="pt-3" enctype="multipart/form-data">
<div class="form-group">
        <label class="form-label required" for="code" >Application {{ trans('fields.code') }}</label>
        <input class="form-control" type="text" name="code" id="code" wire:model.defer="code" >
        <div class="validation-message">
            {{ $errors->first('code') }}
        </div>
        <div class="help-block">
            {{ trans('fields.code_helper') }}
        </div>
    </div>

<input type="file" name="pdf" id="pdf" wire:model="pdfs" multiple >
    <div wire:loading wire:target="pdfs">Uploading...</div>
    @error('pdfs.*') <span class="error">{{ $message }}</span> @enderror

<div class="form-group">
        <button class="mr-2 btn btn-indigo" type="submit">
            {{ trans('global.submit') }}
        </button>
        <a href="{{ route('admin.applicants.index') }}" class="btn btn-secondary">
            {{ trans('global.cancel') }}
        </a>
    </div>
</form>

我需要像这样保存PDF：

$filenames = collect($this->tests)->map->store($this->code.'/'.pdfFileName, 'public');

编辑：

foreach ($this->tests as $file) {
            $name = $file->getClientOriginalName();
            $file->store('moca/'.$this->code.'/'.$name, 'public');

        }

我尝试了这段代码，但在路径$name成为一个文件夹，而不是成为文件的名称
