拉威尔：搜索结果搜索？page=2不显示任何内容，只显示空白页

Question

我的分页工作正常，但是当使用搜索组件时，它只显示结果的第一页。我的页面URL没有搜索看起来像：http://localhost:8000/dictionary-management/postcode?page=2它的工作正确。

带搜索的我的第一页URL：http://localhost:8000/dictionary-管理/邮政编码/搜索和它的工作正常。

带搜索的我的第二页URL：http://localhost:8000/dictionary-管理/邮政编码/搜索？页面=2，没有显示内容，只有空白页面。

这是我的控制器搜索方法：

public function search(Request $request) {
    $constraints = [
        'postcode' => $request['postcode'],
        'address' => $request['address']
    ];

    $postcodes = $this->doSearchingQuery($constraints);
    return view('dictionary-mgmt/postcode/index', ['postcodes' => $postcodes, 'searchingVals' => $constraints]);
}

private function doSearchingQuery($constraints) {
    $query = Postcode::query();
    $fields = array_keys($constraints);
    $index = 0;
    foreach ($constraints as $constraint) {
        if ($constraint != null) {
            $query = $query->where( $fields[$index], 'like', '%'.$constraint.'%');
        }

        $index++;
    }
    return $query->Paginate(5);
}

这是我的路线：

Route::resource('dictionary-management/postcode', 'PostCodeController');
Route::post('dictionary-management/postcode/search', PosstCodeController@search')->name('postcode.search');

这是我的索引视图：

@extends('dictionary-mgmt.postcode.base')
@section('action-content')
    <!-- Main content -->
    <section class="content">
      <div class="box">

        <div class="col-sm-4">

这是我的搜索组件：

   <div class="row">
  @php
    $index = 0;
  @endphp
  @foreach ($items as $item)
    <div class="col-md-6">
      <div class="form-group">
          @php
            $stringFormat =  strtolower(str_replace(' ', '', $item));
          @endphp
          <label for="input<?=$stringFormat?>" class="col-sm-3 control-label">{{$title[$index]}}</label>
          <div class="col-sm-9">
            <input value="{{isset($oldVals) ? $oldVals[$index] : ''}}" type="text" class="form-control" name="<?=$stringFormat?>" id="input<?=$stringFormat?>" placeholder="{{$title[$index]}}">
          </div>
      </div>
    </div>
  @php
    $index++;
  @endphp
  @endforeach
</div>

请帮忙，我不知道我的错在哪里。。。

试试这个

 {{ $postcodes->appends(request()->input())->links()}}

而不是{$postcodes-
