以上是html部分，下面是php部分
public function getsearch(){ //这个方法是表单点击搜索时action提交的方法 $client = ClientBuilder::create()->build(); $keys = Request::instance()->param('keyword'); $keys = $keys ? $keys : '测试'; $params = [ 'index' => 'article_index', 'type' => 'article_type', 'body' => [ 'query' => [ 'match' => [ 'content' => $keys ] ] ] ]; $response = $client->search($params); $str = ''; $list = $response['hits']['hits']; //pp($list);die; $str .= '<script src="https://cdn.staticfile.org/jquery/1.10.2/jquery.min.js"></script> <!-- 最新版本的 Bootstrap 核心 CSS 文件 --> <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap@3.3.7/dist/css/bootstrap.min.css"> <!-- 最新的 Bootstrap 核心 JavaScript 文件 --> <script src="https://cdn.jsdelivr.net/npm/bootstrap@3.3.7/dist/js/bootstrap.min.js"></script>'; $str .= '<table class="table table-hover"> <thead> <tr> <th>id</th> <th>title</th> <th>content</th> </tr> </thead> <tbody>'; foreach ($list as $k => $v) { $str .= '<tr><td>' . $v['_source']['id'] .

最终效果
