关于上传大文件的TokenMismatchException

I want to upload a big file and I get TokenMismatchException it works on small files and I DID add csrf_field but it still gives me this error.

I changed the upload_max_filesize post_max_size and I reset wamp but I get this error.

form:

<form  action="/upload" method="post" enctype="multipart/form-data">
            {{ csrf_field()}}
            <input type="file" name="file">
            <button type="submit">send</button>
</form>

controller:

public function index2(Request $request){
    $file=$request->file('file');
    $file->move('test','test.zip');
    return 'done';
}

if you upload more then your server's post_max_size setting the input will be empty, hence a token miss-match so if you have 2 upload input's in your form and your upload_max_filesize is 2G, your post_max_size needs to be at least 4G
