Php Laravel文件上载而不更改名称

我想上传一个文件到我的laravel项目。但我认识到拉威尔随机更改了我的文件名。如何将文件上载到laravel而不更改其名称。不知何故，我的验证也不起作用。我刚刚被重定向，没有任何消息。 这是我的刀

//show errors
@if ($errors->any())
    <div class="alert alert-danger">
        <ul>
        @foreach ($errors->all() as $error)
            <li>{{ $error }}</li>
        @endforeach
         /ul>
    </div>
@endif
// forms
<form action="{{ route('designers.store') }}" method="post" enctype="multipart/form-data">
    {{ csrf_field() }}
    <div class="form-group d-flex flex-column">
        <label for="exampleInputFile">File input</label>
        <input type="file" name="files[]" multiple>
    </div>
    <button type="submit">Submit</button>
</form>

您可以将控制器更改为：

use Illuminate\Support\Facades\Storage;

function yourFunction(){
    $this->validate($request,[
        'project'   => 'required|numeric',
        'totalItem' => 'required|numeric',
        'files'     => 'nullable|array|file|mimes:pdf,jpg,png,docx,xlsx' //This validates file and MIME type. Also if it isn't required, it should perhaps be nullable.
        ]);
    if($request->hasFile('files'){
        $files = $request->file('files');
        foreach($files as $file){
            $filename = $file->getClientOriginalName();
            Storage::disk('local')->put($filename, file_get_contents($file)); //This stores your file.
        }
    }
    //Save stuff to DB here
}

关于文件存储的正式文件： 关于MIME验证的正式文件：

use Illuminate\Support\Facades\Storage;

function yourFunction(){
    $this->validate($request,[
        'project'   => 'required|numeric',
        'totalItem' => 'required|numeric',
        'files'     => 'nullable|array|file|mimes:pdf,jpg,png,docx,xlsx' //This validates file and MIME type. Also if it isn't required, it should perhaps be nullable.
        ]);
    if($request->hasFile('files'){
        $files = $request->file('files');
        foreach($files as $file){
            $filename = $file->getClientOriginalName();
            Storage::disk('local')->put($filename, file_get_contents($file)); //This stores your file.
        }
    }
    //Save stuff to DB here
}
