Laravel 5 如何在数据提交时替换中间件中的数据

在Laravel5.8应用程序中，在提交带有数据的表单后，我需要清除数据，比如双空格，所以我创建了中间件 带清算代码：

app/Http/Middleware/WorkTextString.php：

<?php

namespace App\Http\Middleware;

use Closure;
use App\Http\Traits\funcsTrait;
use function PHPSTORM_META\type;

class WorkTextString
{

    use funcsTrait;
    public function handle($request, Closure $next, $strip_tags_excluding= false )
    {
        $inputDataArray = $request->all();

        \Log::info($request->all());


        $stripTagsExcludingArray= $this->pregSplit('/ /',$strip_tags_excluding);
        foreach( $inputDataArray as $next_field_name=>$next_field_value ) {
            if ( !empty($next_field_value) and is_string($next_field_value) ) {
                $skip_strip_tags= in_array($next_field_name,$stripTagsExcludingArray);
                $inputDataArray[$next_field_name] = $this->workTextString($next_field_value, $skip_strip_tags);
            }
        }

        \Log::info('$inputDataArray:: ::');  // I CHECK AND SEE CLEARED DATA!
        \Log::info($inputDataArray);

        $request->replace($inputDataArray); // THAT DOWS NOT WORK ?

        return $next($request);
    }

}

已修改： 我找到一篇文章 在阅读这篇文章时，我想我必须使用中间件的cleanData，所以我评论了以前使用的方法并添加了 方法：

只是为了检查和替换任何值

但我在日志文件中出错：

而且没有我在\Log:：info中写的消息。。。 哪条路是对的

---

如何正确执行？

我在模型中找到了一个决策方法，用于任何需要清除的字段：

public function setNameAttribute($value)
{
    $this->attributes['name'] = $this->workTextString($value);
}

---

没有中间件，它对我有效

尝试使用

$request->merge

方法我尝试了$request->merge（$inputDataArray）；返回$next（$request）；再次存档-我的数据清除不是AppliedPL，请查看ModifiedWho在中间件中替换了提交的数据，请给出一个提示，您使用了哪种方法？您必须使用更新的数据调用merge。类似这样的内容：

$inputdataarraywhithouttags=removeUnwantedTags（$inputDataArray）
$request->merge（$inputDataArrayWithoutTags）
返回$next（$request）
