Laravel 5.2 LengthAwarePaginator在导航到下一页时不显示任何结果

Question

我使用的是LengthAwarePaginator，它将从Twitter api获得的结果分页。第一页工作得很好但是当我通过分页链接导航到任何其他页面时，它不会给出任何结果。

路线：

Route::any('/search', ['uses' => 'TweetController@getSearch', 'as' => 'search']);

TweetController：

public function getSearch(Request $request)
{
    $currentPage = LengthAwarePaginator::resolveCurrentPage();

    $perPage = 6;

    $tweetArray = Twitter::getUserTimeline(['screen_name' => $request['search'], 'count' => $request['count']]);

    $tweetPerPage = array_slice($tweetArray, (($currentPage-1) * $perPage), $perPage, true);

    $tweets = new LengthAwarePaginator($tweetPerPage, count($tweetArray), $perPage, $currentPage, ['path' => $request->url()]);

    return view('tweets', ['tweets' => $tweets]);
}

tweet.blade.php：

<div class="row">
    <form action="{{ route('search') }}" method="post">
        <div class="col-md-5 col-md-offset-3">
            <div class="input-group">
                <span class="input-group-addon" id="basic-addon1">@</span>
                <input type="text" class="form-control" placeholder="Search using Twitter Handle" name="search" aria-describedby="basic-addon1">
                <div class="input-group-btn">

                        <span class="caret"></span>
                    </button>
                    <ul class="dropdown-menu dropdown-menu-right">
                      <li><a href="#">10</a></li>
                      <li><a href="#">20</a></li>
                      <li><a href="#">30</a></li>

    $('.dropdown-menu > li').click(function() {

        $('.number').html(cnt);
    });
