##1 .First, introduce the sphinxapi class file into Yii2.0. The steps to introduce it are:
(1) Create a new folder libs in the root directory, Place the class file sphinxapi.php into the libs folder.
(2.) Then add Yii::$classMap to the web.php configuration in the config folder of the root directory. ['SphinxClient'] = '@app/libs/sphinxapi.php';
(3.) Use in the controller use SphinxClient;
(4.) I use two tables here, the blog post table ex_blog and the blog post classification table ex_blog_type

/* * Sphinx搜索 */ public function actionSearch(){ //判断是否是POST提交 if(\Yii::$app->request->isPost){ $title = \Yii::$app->request->post('title'); //$author = \Yii::$app->request->post('author'); //$type_name = \Yii::$app->request->post('type_name'); $sphinx = new SphinxClient(); $sphinx->SetServer('127.0.0.1',9312); //SPH_MATCH_ALL匹配所有查询词(默认模式) $sphinx->SetMatchMode ( SPH_MATCH_ALL); //匹配查询词中的任意一个 $sphinx->SetMatchMode ( SPH_MATCH_ANY); //将整个查询看作一个词组,要求按顺序完整匹配 $sphinx->SetMatchMode ( SPH_MATCH_PHRASE); $data = $sphinx->Query("$title","*"); //判断键值是否存在 if(!array_key_exists("matches",$data)){ exit("没有检索到您需要的信息"); } // 1.Matches中就是查询的结果了,但是仿佛不是我们想要的数据。 // 2.根据官方的说明是Sphinx并没有连接到MySQL去取数据,只是根据它自己的索引内容进行计算; // 3.因此如果想用Sphinx提供的API去取得我们想要的数据,还必须以查询的结果为依据(也就是ID为依据); // 4.根据ID再次查询MySQL从而得到我们想要的数据。 //获取主键 (这里的主键就是数据在数据库中的自增ID) 通过ID在根据数据库 查询出数据 $key = array_keys($data['matches']); //把数组元素组合为一个字符串 $key = join(',',$key); //根据获取到的ID在查询数据库 $query = new \yii\db\Query(); //使用框架中的in 哈希格式 来检索 $blogInfo = $query->from(['b'=>'ex_blog','bt'=>'ex_blog_type'])->where(['id'=>[$key]])->all(); //将数组转换为Json类型 echo json_encode($blogInfo); }else{ echo "非正常提交"; } }

<script> function search(){ //获取搜索的数据 var title = $("#title").val(); var author = $("#author").val(); var type_name = $("#type_name").val(); //发送AJAX请求 $.ajax({ url:"?r=sphinx/search", data:{title:title,author:author,type_name:type_name}, type:"POST", success:function(msg){ //alert(msg); //将JSON数据转换为对象 obj = eval("("+msg+")"); var table = ''; table += '<table border="1" align="center" width="800" style="text-align: center">' table += '<tr id="tr">'; table += '<td>编号</td>'; table += '<td>标题</td>'; table += '<td>作者</td>'; table += '<td>类型</td>'; table += '<td>封面</td>'; table += '<td>添加时间</td>'; table += '<td>操作</td>'; table += '</tr>'; for(var i in obj){ table += "<tr class='content'>" table += "<td>"+obj[i].id+"</td>"; table += "<td>"+obj[i].title+"</td>"; table += "<td>"+obj[i].author+"</td>"; table += "<td>"+obj[i].type_name+"</td>"; table += '<td><img src='+obj[i].pic+' alt="封面" width="50" height="50"></td>'; table += "<td>"+obj[i].time+"</td>"; table += "<td> <a href=''>删除</a> | <a href=''>编辑</a> </td>"; table += "</tr>" } table += '</table>'; //将表格赋值到页面 $("#table").html(table); //将原有的内容移除 //$(".content").remove(); //将返回的数据追加到原来位置 //$("#tr").after(tr); } }); } </script>

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4.
