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

Vue3+Ts封装Axios及Vue的Proxy配置 一、开箱即用的axios封装：Vue3+ts作者：诸葛小愚链接：https://juejin.cn/post/7107047280133275678来源：稀土掘金著作权归作者所有。商业转载请联系作者获得授权，非商业转载请注明出处。新建index.ts文件：需要定义请求返回的数据格式，这个可以和服务端约定好数据格式需要定义axios的配置信息，用于在创建axios实例时传入请求拦截器，前端所有的接口请求都会先达到请求拦截器，我们可以在此添加请求头信息响应拦截器，服务端返回的数据会先达到响应拦截器，我们可以处理服务端的响应信息。如果是报错，就处理常见的报错；如果是成功，就返回数据封装常用的get、put、post、delete接口方法封装axiosimport axios, {AxiosInstance, AxiosError, AxiosRequestConfig, AxiosResponse} from 'axios' import {ElMessage} from 'element-plus' // 数据返回的接口 // 定义请求响应参数，不含data interface Result { code: number; msg: string } // 请求响应参数，包含data interface ResultData<T = any> extends Result { data?: T; } const URL: string = '' enum RequestEnums { TIMEOUT = 20000, OVERDUE = 600, // 登录失效 FAIL = 999, // 请求失败 SUCCESS = 200, // 请求成功 } const config = { // 默认地址 baseURL: URL as string, // 设置超时时间 timeout: RequestEnums.TIMEOUT as number, // 跨域时候允许携带凭证 withCredentials: true } class RequestHttp { // 定义成员变量并指定类型 service: AxiosInstance; public constructor(config: AxiosRequestConfig) { // 实例化axios this.service = axios.create(config); /** * 请求拦截器 * 客户端发送请求 -> [请求拦截器] -> 服务器 * token校验(JWT) : 接受服务器返回的token,存储到vuex/pinia/本地储存当中 */ this.service.interceptors.request.use( (config: AxiosRequestConfig) => { const token = localStorage.getItem('token') || ''; return { ...config, headers: { 'x-access-token': token, // 请求头中携带token信息 } } }, (error: AxiosError) => { // 请求报错 Promise.reject(error) } ) /** * 响应拦截器 * 服务器换返回信息 -> [拦截统一处理] -> 客户端JS获取到信息 */ this.service.interceptors.response.use( (response: AxiosResponse) => { const {data, config} = response; // 解构 if (data.code === RequestEnums.OVERDUE) { // 登录信息失效，应跳转到登录页面，并清空本地的token localStorage.setItem('token', ''); // router.replace({ // path: '/login' // }) return Promise.reject(data); } // 全局错误信息拦截（防止下载文件得时候返回数据流，没有code，直接报错） if (data.code && data.code !== RequestEnums.SUCCESS) { ElMessage.error(data); // 此处也可以使用组件提示报错信息 return Promise.reject(data) } return data; }, (error: AxiosError) => { const {response} = error; if (response) { this.handleCode(response.status) } if (!window.navigator.onLine) { ElMessage.error('网络连接失败'); // 可以跳转到错误页面，也可以不做操作 // return router.replace({ // path: '/404' // }); } } ) } handleCode(code: number):void { switch(code) { case 401: ElMessage.error('登录失败，请重新登录'); break; default: ElMessage.error('请求失败'); break; } } // 常用方法封装 get<T>(url: string, params?: object): Promise<ResultData<T>> { return this.service.get(url, {params}); } post<T>(url: string, params?: object): Promise<ResultData<T>> { return this.service.post(url, params); } put<T>(url: string, params?: object): Promise<ResultData<T>> { return this.service.put(url, params); } delete<T>(url: string, params?: object): Promise<ResultData<T>> { return this.service.delete(url, {params}); } } // 导出一个实例对象 export default new RequestHttp(config);实际使用在使用时，我们需要在API文档中导入index.ts，会自动创建一个axios实例。我们在同目录下，新建一个login.tsimport axios from './' namespace Login { // 用户登录表单 export interface LoginReqForm { username: string; password: string; } // 登录成功后返回的token export interface LoginResData { token: string; } } // 用户登录 export const login = (params: Login.LoginReqForm) => { // 返回的数据格式可以和服务端约定 return axios.post<Login.LoginResData>('/user/login', params); }API接口也定义好了，再来一个页面简单试试：<script setup> import { reactive } from 'vue'; import {login} from '@/api/login.js' const loginForm = reactive({ username: '', password: '' }) const Login = async () => { const data = await login(loginForm) console.log(data); } </script> <template> <input v-model="loginForm.username" /> <input v-model="loginForm.password" type="password" /> <button @click="Login">登录</button> </template>二、Vue通过Proxy访问不同端口的API后台API使用Springboot开发,部署端口为81251.Vue项目根目录创建vue.config.jsmodule.exports = { devServer: { open: true, host: "127.0.0.1", port: 7123, hot: true, proxy: { "/api": { target: "http://localhost:8125", // 代理地址，这里设置的地址会代替axios中设置的baseURL changeOrigin: true, // 是否跨域 ws: false, // 如果要代理 websockets，配置这个参数 pathRewrite: { "^/api": "", }, }, }, }, };2.示例请求apis/index.ts... const URL = "/api"; ...apis/register.ts... // 用户注册 export const register = (params: RegisterReqForm) => { return axios.post<number>("/user/register", params); }; ...pages/login/Login.ts... async handleRegisterSubmit() { const data = await register(this.registerForm); message.success("用户注册成功"); }, ...根据如上代码可得请求地址为:/api/user/register,并没有host代理后的地址为:http://127.0.0.1:8125/user/register这样就实现前端127.0.0.1:7123代理请求访问127.0.0.1:8125引用1.开箱即用的axios封装：Vue3+ts:https://juejin.cn/post/7107047280133275678#heading-22.Proxy error: Could not proxy request... 问题解决:https://blog.csdn.net/ymiandi/article/details/125674056
