Laravel+Scout+Elasticsearch实现中文分词搜索功能 一、准备工作1.配置机器ssh连接sudo apt update sudo apt install openssh-server # ssh二、Docker安装ElasticSearch2.1 安装说明在平时工作的时候，开发环境大多数会安装单机ElasticSearch，但生产环境基本会安装ElasticSearch集群版。不过中文搜索，会实现分词器集成，可以采用IK分词器。ElasticSearch采用Kibana实现数据可视化分析也是当前主流，所以我们除了安装ElasticSearch和IK分词器外，还需要安装Kibana。安装实践:1:ElasticSearch单机安装 2:IK分词器安装 3:Kibana安装 2.2 Docker安装ElasticSearch当前ElasticSearch已经到了8.0，新版本都有很多新特性，性能和功能都有大幅提升，我们建议使用较高版本，这里将采用8.6.0版本。 2.2.1 网络创建高版本安装Kibana的时候需要和ElasticSearch在同一网段内，所以采用docker安装首先要确认网段，为了方便操作，我们直接创建一个网络，创建脚本如下:sudo docker network create elastic-series2.2.2 ElasticSearch安装安装ElasticSearch脚本如下:sudo docker run -d \ --name elasticsearch \ -e "ES_JAVA_OPTS=-Xms512m -Xmx512m" \ -e "discovery.type=single-node" \ -v es-data:/usr/share/elasticsearch/data \ -v es-plugins:/usr/share/elasticsearch/plugins \ --privileged \ --network elastic-series \ -p 9200:9200 \ -p 9300:9300 \ elasticsearch:8.6.0命令说明：-e "cluster.name=es-docker-cluster"：设置集群名称-e "http.host=0.0.0.0"：监听的地址，可以外网访问-e "ES_JAVA_OPTS=-Xms512m -Xmx512m"：内存大小-e "discovery.type=single-node"：非集群模式-v es-data:/usr/share/elasticsearch/data：挂载逻辑卷，绑定elasticsearch的数据目录-v es-logs:/usr/share/elasticsearch/logs：挂载逻辑卷，绑定elasticsearch的日志目录-v es-plugins:/usr/share/elasticsearch/plugins：挂载逻辑卷，绑定elasticsearch的插件目录--privileged：授予逻辑卷访问权--network elastic-series ：加入一个名为elastic-series的网络中-p 9200:9200：端口映射配置Docker安装ElasticSearch下载可能会比较慢，需要耐心等待，效果如下：安装完成后，在浏览器中输入：http://192.168.211.128:9200/即可看到elasticsearch的响应结果：You can Generate a new password using/usr/share/elasticsearch/elasticsearch-setup-passwords auto/interactiveinteractive is where you will have to enter password for all user.auto will just print passwords on the shell.elseYou can turn off x-pack security in elasticsearch.yml2.2.2.1 关闭安全验证1.进入容器内部sudo docker exec -it -u root <container> bash2.安装Vim,为编辑文件做准备apt-get update apt-get install vim3.编辑config/elasticsearch.yml# 追加 xpack.security.enabled: false4.退出并重启容器exit sudo docker restart <container>刷新页面,得到正常响应 3 安装Kibana我们可以基于Http请求操作ElasticSearch，但基于Http操作比较麻烦，我们可以采用Kibana实现可视化操作。2.2.2.2 设置密码详见引用第九条三、Docker安装Kibana3.1 Kibana介绍Kibana 是一个免费且开放的用户界面，能够让您对 Elasticsearch 数据进行可视化，并让您在 Elastic Stack 中进行导航。您可以进行各种操作，从跟踪查询负载，到理解请求如何流经您的整个应用，都能轻松完成。Kibana 让您能够自由地选择如何呈现自己的数据。不过借助 Kibana 的交互式可视化，您可以先从一个问题出发，看看能够从中发现些什么。 可视化界面如下： 3.2 Kibana安装使用Docker安装Kibana非常简单，只需要执行如下命令即可，但是执行命令需要注意Kibana操作的ElasticSearch地址，因为Kibana是需要连接ElasticSearch进行操作的，命令如下:sudo docker run -d \ --name kibana \ -e ELASTICSEARCH_HOSTS=http://192.168.211.128:9200 \ --network elastic-series \ -p 5601:5601 \ kibana:8.6.0命令说明：--network elastic-series ：加入一个名为elastic-series的网络中，与elasticsearch在同一个网络中-e ELASTICSEARCH_HOSTS=http://192.168.211.128:9200"：设置elasticsearch的地址，因为kibana已经与elasticsearch在一个网络，因此可以用容器名直接访问elasticsearch，也可以写IP地址实现访问。-p 5601:5601：端口映射配置安装的时候如果没有镜像，会下载镜像，效果如下：kibana安装会比较耗时间，也需要耐心等待下载安装完成，如果想实时知道服务安装运行的状态，可以通过查看日志实现，查看日志如下：docker logs -f kibana日志中如果出现了http://0.0.0.0:5601即可访问Kibana后台服务，日志如下：访问http://192.168.211.128:5601效果如下：可以点击Add integrations，添加示例数据，如下图，随意选一个即可，不选其实也是可以的。 3.3 Kibana中文配置我们发现Kibana是英文面板，看起来不是很方便，但Kibana是支持中文配置，所以我们可以把Kibana配置成中文版，便于我们操作。切换中文操作如下:#进入容器 docker exec -it kibana /bin/bash #进入配置文件目录 cd /usr/share/kibana/config #编辑文件kibana.yml vi kibana.yml #在最后一行添加如下配置 i18n.locale: zh-CN #保存退出 exit #并重启容器 docker restart kibana 等待Kibana容器启动，再次访问http://192.168.211.128:5601/效果如下： 四、IK分词器安装我们打开Kibana，点击开发工具，操作如下：输入如下操作，用于查询分词：上图测试代码如下:GET _analyze { "analyzer": "standard", "text": "过去无可挽回,未来可以改变" }表示使用standard对过去无可挽回,未来可以改变进行分词。分词：提取一句话或者一篇文章中的词语。我们在使用ElasticSearch的时候，默认用standard分词器，但standard分词器使用的是按空格分词，这种分词操作方法不符合中文分词标准，我们需要额外安装中文分词器。 4.1 IK分词器介绍IK Analyzer是一个开源的，基于java语言开发的轻量级的中文分词工具包。从2006年12月推出1.0版开始， IKAnalyzer已经推出了多个大版本。最初，它是以开源项目Luence为应用主体的，结合词典分词和文法分析算法的中文分词组件。IK Analyzer则发展为面向Java的公用分词组件，独立于Lucene项目，同时提供了对Lucene的默认优化实现。 ElasticSearch内核其实就是基于Lucene，所以我们可以直接在ElasticSearch中集成IK分词器，IK分词器集成ElasticSearch下载地址：https://github.com/medcl/elasticsearch-analysis-ik/releases 4.2 IK分词器配置下载安装包elasticsearch-analysis-ik-8.6.0.zip后，并解压，目录如下：我们只需要将上面ik拷贝到ElasticSearch的plugins目录中即可，但由于当前服务采用的是docker安装，所以需要将文件拷贝到docker容器的plugins目录才行。操作如下：#将ik文件夹拷贝到elasticsearch容器中 docker cp ik elasticsearch:/usr/share/elasticsearch/plugins #重启容器 docker restart elasticsearch操作效果如下： 4.3 分词测试IK分词器包含两种模式：ik_smart：最少切分ik_max_word：最细切分 前面使用默认的standard分词器，对中文分词非常难用，安装IK分词器后，我们可以使用IK分词器测试，测试代码如下：GET /_analyze { "analyzer": "ik_max_word", "text": "过去无可挽回,未来可以改变" }测试效果如下：我们可以发现对中文的分词效果是比较不错的，但也存在一些不足，比如无可挽回我们希望它是一个词，而可挽回我们希望它不被识别一个词，又该如何实现呢？自定义词典参考引用中的第2个链接五、Laravel集成使用的第三方包matchish/laravel-scout-elasticsearch:https://github.com/matchish/laravel-scout-elasticsearch名称版本php^8.0.2laravel/framework^9.19matchish/laravel-scout-elasticsearch^6.05.1 介绍Laravel Scout 为 Eloquent 模型 的全文搜索提供了一个简单的基于驱动程序的解决方案，通过使用模型观察者，Scout 将自动同步 Eloquent 记录的搜索索引。目前，Scout 附带 Algolia、MeiliSearch 和 MySQL / PostgreSQL (database) 驱动程序。此外，Scout 包括一个「collection」驱动程序，该驱动程序专为本地开发使用而设计，不需要任何外部依赖项或第三方服务。此外，编写自定义驱动程序很简单，你可以使用自己的搜索实现自由扩展 Scout。由于没有自带Elasticsearch的驱动,所以需要第三方包5.1 安装包和配置1.引入包composer require matchish/laravel-scout-elasticsearch2.env设置环境变量SCOUT_DRIVER=Matchish\ScoutElasticSearch\Engines\ElasticSearchEngine ELASTICSEARCH_HOST=192.168.211.128:92003.config/app.php中配置provider'providers' => [ // Other Service Providers \Matchish\ScoutElasticSearch\ElasticSearchServiceProvider::class ],4.发布配置文件php artisan vendor:publish --tag config会新增config/elasticsearch.php文件5.2 更新模型1.更新模型<?php namespace App\Models; use App\Trait\DefaultDatetimeFormat; use Illuminate\Database\Eloquent\Model; use Laravel\Scout\Searchable; class Video extends Model { use DefaultDatetimeFormat, Searchable; protected $fillable = ['img', 'title', 'innerVideoHref', 'innerHref', 'viewNumber', 'likeNumber', 'helpInfo', 'type']; /** * Get the indexable data array for the model. * 我想只根据title来分词检索 * @return array */ public function toSearchableArray() { return $this->only(['title']); } /** * Get the index name for the model. * 指定索引的名称 * @return string */ public function searchableAs() { return 'videos_index'; } /** * 指定 搜索索引中存储的唯一ID * @return mixed */ public function getScoutKey() { return $this->id; } /** * 指定 搜索索引中存储的唯一ID的键名 * @return string */ public function getScoutKeyName() { return 'id'; } }2.修改config/elasticsearch.php<?php return [ 'host' => env('ELASTICSEARCH_HOST','192.168.211.128:9200'), 'indices' => [ 'mappings' => [ 'default' => [ 'properties' => [ 'id' => [ 'type' => 'keyword', ], ], ], // 与上一步的索引名称对应 'videos_index' => [ 'properties' => [ 'title' => [ 'type' => 'text', 'analyzer' => 'ik_max_word', 'search_analyzer' => 'ik_max_word', ], ], ], ], 'settings' => [ 'default' => [ 'number_of_shards' => 1, 'number_of_replicas' => 0, ], ], ], ];3.索引的批量导入php artisan scout:import5.3 使用场景：根据当前播放的视频名称,检索出来十个相关的视频作为推荐public function play($type, $id) { // 直接根据类型和视频ID进行查询 $video = Video::where('type', $type)->where('id', $id)->first(); $videoSeries = Video::search($video->title)->take(10)->get(); dd($videoSeries); }六、遇到的问题6.1 Kibana 服务器尚未准备就绪。在服务器上部署时,访问Kibana出现了查看日志docker logs kibana [2023-01-18T02:05:30.467+00:00][ERROR][elasticsearch-service] Unable to retrieve version information from Elasticsearch nodes. connect ECONNREFUSED 127.0.0.1:9200原因是创建容器时填写的sudo docker run -d \ --name kibana \ -e ELASTICSEARCH_HOSTS=http://127.0.0.1:9200 \ -p 5601:5601 \ kibana:8.6.0这里不可以使用127.0.0.1需要使用私有IP重新创建后即可正常访问6.2 无法访问在虚拟机上部署时按照步骤并开放端口是可以访问9200和5601端口在服务器上按照 创建网络 -> 创建elasticsearch、kibana容器设置网络 的步骤走下来 始终访问不了对应的端口不清楚原因,于是去掉了创建容器时的网络配置引用1.如何在 Ubuntu 20.04 启用 SSH

初探Laravel Starters Kits的Breeze&Vue 简介Breeze 是官方推荐的起手套装，内建有登入、注册、忘记密码等常用的用户功能，另外可以选择使用 Vue 或者 React 来建立SPA单页页面。首先，Breeze 适用于专门初始化的工具，如果项目已经开发到一半的话可能会有冲突，所以不适用。最好建立一个初始化的工程。创建工程1.创建项目如果是8或更低的版本中前端资源打包使用了mix执行npm install 和 npm run dev后，页面无法正常解析，属于是坑了解决方案：https://learnku.com/laravel/t/69192所以避免踩坑直接采用了最新版的v 9.3.3的Laravelcomposer create-project laravel/laravel=9.*.* --prefer-dist projectName2.安装breezecomposer require laravel/breeze --dev官方文档:https://laravel.com/docs/9.x/starter-kits#laravel-breeze-installation3.安装breeze & React/Vuephp artisan breeze:install vue # Or... php artisan breeze:install react php artisan migrate npm install npm run dev4.查看效果需要跑两个控制台图中左侧运行服务端:php artisan serve右侧运行前端:npm run dev访问http://127.0.0.1:8000查看!自带了登录、注册功能，单页应用全程无刷新，nice!架构分析探索一下 Laravel 是如何实现这些的1.浅析路由和组件首先看到 routes/auth.php,这里定义了使用者登录之前的页面路由与 API,包含注册、登入登出、忘记密码等。以 Get/login 为例，由 AuthenticatedSessionController 的 create 方法处理请求后回传登录页面。 在这之前加上了 guest 这个 middleware，如果请求带有已登录的状态，则不回传页面而直接跳到首页。Route::middleware('guest')->group(function () { // ... Route::get('login', [AuthenticatedSessionController::class, 'create']) ->name('login'); // ... });看看 AuthenticatedSessionController 的 create方法做了什么/** * Display the login view. * * @return \Inertia\Response */ public function create() { return Inertia::render('Auth/Login', //resources\js\Pages\Auth\Login.vue 页面组件 // 页面组件的Props参数 [ 'canResetPassword' => Route::has('password.request'), 'status' => session('status'), ]); }再看一下对应的Vue组件<script> defineProps({ canResetPassword: Boolean, status: String, }); </script> <template> ... <div v-if="status" class="mb-4 font-medium text-sm text-green-600"> {{ status }} </div> ... ... <Link v-if="canResetPassword" :href="route('password.request')" class="underline text-sm text-gray-600 hover:text-gray-900"> Forgot your password? </Link> ... </template>瞬间明白，php中可以直接返回信息回传给Inertia.js进行渲染页面，组件中进行defineProps声明后即可使用。2.Inertia原理這邊簡單說下 Inertia.js 的運作方式，最初連上網站的時候，會回傳一個帶有 Inertia 功能的全頁應用，而這個應用裡所有的 link 都會經過 Inertia 的處理，當點擊 link 時並不會直接跳轉網址而是變成發送一個 XHR 到 Laravel ，並經由 API 回傳 Inertia 渲染的畫面元件，進行畫面的更新。而說是 API 渲染元件其實有點不太準確，收到請求後 Inertia Render 會將 Vue/React 元件轉換成 JSON 並回傳(不是 Html)，再經由前端的 Inertia 解析後重新渲染部分的畫面，達到類前端 App 的效果，所以實際的渲染還是發生在前端，API 只是提供資料。另外這個方法前端是沒有路由器的，Laravel 伺服器提供畫面的路由器替代了這部分。本段来自:https://ithelp.ithome.com.tw/articles/10267034?sc=iThelpR3.Vue目录结构进一步学习留个官方文档入口: https://laravel.com/docs/9.x/vite引用1.Laravel8.5使用套件laravel breeze ,所有页面版式都未正确加载:https://learnku.com/laravel/t/691922.Laravel Starter kits :https://laravel.com/docs/9.x/starter-kits#introduction3.使用 Breeze 建立基礎專案框架:https://ithelp.ithome.com.tw/articles/10267034?sc=iThelpR4.Migrating from Laravel Mix to Vite:https://github.com/laravel/vite-plugin/blob/main/UPGRADE.md#migrating-from-laravel-mix-to-vite5.Bundling Assets (Vite)：https://laravel.com/docs/9.x/vite

使用Nginx反向代理接入欣赏小姐姐视频站点 前言最近网上冲浪发现了这种欣赏小姐姐的视频站点 ::(你懂的) ，于是想整一个集成到blog里。源站点： 欣赏小姐姐：https://xjiejie.vip/ 成果展示: 欣赏小姐姐：https://www.lisok.cn/online-tiktok.html1.先抓包拿接口😋 对方的反扒意识蛮强的 1.屏蔽了页面上的右键 2.F12打开开发者工具，页面会自动关闭 3.若可以成功打开开发者工具，那么页面在请求数据的时候还会再次检测，若被发现页面会自动关闭。于是干脆放弃用开发者工具了,直接上Fiddler成功拿到接口:URL:https://xjiejie.vip/zb_users/theme/lanyexvideo/include/video.php Param: # 随机值,防止懒请求： t:xxx Header: # 模拟请求的过程中发现有防盗链,校验Referer请求头 Referer:https://xjiejie.vip/ 2.页面请求博客的网络请求用的JQuery,那请求就由Ajax负责：index.html$(".getUrl").click(function () { let url = "https://xjiejie.vip/zb_users/theme/lanyexvideo/include/video.php?t=" + Math.random(); $.ajax({ url: url, type: "GET", dataType: "json", success: function (data) { console.log(data); $("#video").attr("src", data.playurl); }, }); });遇到了跨域问题,意料之中,这肯定不能让对方服务器去加响应头,只得我们自己去做一个代理访问。3.PHP代理流程：由原来的前端直接访问对方服务器 变成了 前端访问自己的代理PHP文件，再由PHP去向对方服务器发起请求返回结果。proc.php<?php // 对方的响应有gzip压缩，需要解压缩 function gunzip($zipped) { $offset = 0; if (substr($zipped, 0, 2) == "\x1f\x8b") $offset = 2; if (substr($zipped, $offset, 1) == "\x08") { return gzinflate(substr($zipped, $offset + 8)); } return "Unknown Format"; } // 发起网络请求 $url = 'https://xjiejie.vip/zb_users/theme/lanyexvideo/include/video.php?t=' . time(); // 发起GET请求 $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // 设置请求头 curl_setopt($ch, CURLOPT_HTTPHEADER, array( 'Content-Type: application/json', 'Accept: application/json', 'Referer: https://xjiejie.vip/', 'Accept-Encoding: gzip, deflate, br', )); // 关闭ssl curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false); curl_setopt($ch, CURLINFO_HEADER_OUT, 0); curl_setopt($ch, CURLOPT_HEADER, 0); $output = curl_exec($ch); // 若有错误，则抛出异常 if (curl_errno($ch)) { echo 'Error:' . curl_error($ch); exit; } curl_close($ch); // 输出结果 $arr = []; // 获取请求头的Referer $arr = json_decode(gunzip($output), true); $arr['referer'] = $_SERVER['HTTP_REFERER']; $arr['host'] = $_SERVER['HTTP_HOST']; // 输出json header('Content-Type: application/json'); echo json_encode($arr);对应的前端的请求路径也要修改index.htmllet url = "/proc.php" + Math.random();4.Nginx代理最近刚开始学习Nginx,边查资料边测试，实现了这个功能4.1 编写配置文件直接在网站的配置文件中做如下修改：lisok.cn.... location /xjiejie/video/ { proxy_pass https://xjiejie.vip/zb_users/theme/lanyexvideo/include/video.php; proxy_set_header Referer "https://xjiejie.vip/"; proxy_set_header Content-Type "application/json"; proxy_set_header Accept-Encoding "gzip, deflate, br"; proxy_set_header User-Agent "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/103.0.0.0 Safari/537.36"; proxy_set_header Accept "application/json"; proxy_set_header Host "xjiejie.vip"; } location / { # ！！！原先下三行的内容是没有在 location / 中的！！！ #REWRITE-START URL重写规则引用,修改后将导致面板设置的伪静态规则失效 include /www/server/panel/vhost/rewrite/lisok.cn.conf; #REWRITE-END } ....index.htmllet url = "/xjiejie/video?t=" + Math.random(); $.ajax({ url: url, type: "GET", dataType: "json", success: function (data) { console.log(data); $("#video").attr("src", data.playurl); }, }); });更新:2022.9.8 更新接口今天访问的时候发现不能播放视频了,查看接口发现对方更换了域名nginx配置文件也进行同步更新即可 location /xjiejie/video { proxy_pass https://xjiejie.co/zb_users/theme/lanyexvideo/include/video.php; proxy_set_header Referer "https://xjiejie.co/"; proxy_set_header Content-Type "application/json"; proxy_set_header Accept-Encoding "gzip, deflate, br"; proxy_set_header User-Agent "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/103.0.0.0 Safari/537.36"; proxy_set_header Accept "application/json"; proxy_set_header Host "xjiejie.co"; }5.注意事项PHPStudy集成的是Nginx v1.15.11，这版本使用中会有问题,即使修改了Referer后，反向代理访问对方的站点还是会返回404,后面升级到Nginx v1.16.1就好了。typecho会有伪静态的配置,若先加载的伪静态配置会导致访问接口时候返回页面未找到的404错误，所以nginx的配置项要先于伪静态的配置项。
