https://github.com/medcl/elasticsearch-analysis-ik 文档
elasticsearch基本概念
索引index
类型type
文档document
字段field
模板template
es标准查询地址
http://localhost:991/myindex/share/1
索引名称/索引类型名称/索引文档唯一标识
搜索模板的基本步骤
1.安装elasticsearch和ik插件
2. elasticsearch的laravel scout包安装
3. 创建ylaravel的索引和模板
4.导入数据库已有的数据
5. 搜索页面和逻辑展示
安装
1.安装elasticsearch和ik插件
https://github.com/medcl/elasticsearch-rtf 集成包
主要使用 bin/elasticsearch-plugin list analysis-ik插件,其他的可删除
启用插件
bin/elasticsearch -d
查看 ps aux |grep java
ll
vim logs/elasticsearch.log
9200 9300
2.安装laravel使用elastic的包
安装laravel/scout (5.4开始使用)
http://d.laravel-china.org/docs/5.4/scout (使用说明)
1. composer require laravel/scout
2. config/app.php 中添加 Laravel\Scout\ScoutServiceProvider::class,
3. php artisan vendor:publish --provider="Laravel\Scout\ScoutServiceProvider"
安装scout的驱动
https://github.com/ErickTamayo/laravel-scout-elastic
1. composer require tamayo/laravel-scout-elastic
2. config/app.php 中添加 ScoutEngines\Elasticsearch\ElasticsearchProvider::class,
修改scout.php
config/scout.php
1. 'driver' => env('SCOUT_DRIVER', 'elasticsearch'),
2. 'elasticsearch' => [
'index' => env('ELASTICSEARCH_INDEX', 'laravel'),
'hosts' => [
env('ELASTICSEARCH_HOST', 'http://localhost'),
],
],
自定义脚本创建es的index和template
创建command
php artisan make:command ESInit
\app\Console\Commands\ESInit.php 修改
protected $signature = 'es:init';//使用什么命令来启动
protected $description = 'init larave es for post ';//命令描述
挂载
\app\Console\Kernel.php 修改
protected $commands = [
\App\Console\Commands\ESInt::class
//
];
执行 php artisan 查看是否添加
编辑handle
composer require guzzlehttp/guzzle
\app\Console\Commands\ESInit.php 修改
use GuzzleHttp\Client;
public function handle()
{
$client = new Client();
// 创建模版
$url = config('scout.elasticsearch.hosts')[0] . '/_template/tmp';
$client->put($url, [
'json' => [
'template' => config('scout.elasticsearch.index'),
'settings' => [
'number_of_shards' => 1
],
'mappings' => [
'_default_' => [
'_all' => [
'enabled' => true
],
'dynamic_templates' => [
[
'strings' => [
'match_mapping_type' => 'string',
'mapping' => [
'type' => 'text',//分析成文本
'analyzer' => 'ik_smart',//使用ik_smart
'ignore_above' => 256,
'fields' => [
'keyword' => [
'type' => 'keyword'
]
]
]
]
]
]
]
]
]
]);
$this->info("========创建模板成功===========");
//创建index
$url = config('scout.elasticsearch.hosts')[0] . '/' . config('scout.elasticsearch.index');
$client->put($url, [
'json' => [
'settings' => [
'refresh_interval' => '5s',
'number_of_shards' => 1,
'number_of_replicas' => 0,
],
'mappings' => [
'_default_' => [
'_all' => [
'enabled' => false
]
]
]
]
]);
$this->info("========创建index成功===========");
}
导入文章的数据
post.php (model)
use Laravel\Scout\Searchable;//加入特性
//定义索引里的type
public function searchableAs(){
return "post";
}
//定义那些字段可被搜索
public function toSearchableArray(){
return [
'title'=>$this->title,
'content'=>$this->content
];
}
命令行导入
php artisan scout:import "\App\Post"
搜索
public function search()
{
$this->validate(request(),[
'query' => 'required'
]);
$query = request('query');
$posts = Post::search(request('query'))->paginate(10);
return view('post/search', compact('posts', 'query'));
}
对应关系
<!-- 粉丝用户 -->
public function fuser(){
return $this->hasOne(\App\User::class,'id','fan_id');
}
<!-- 用户文章列表 -->
public function posts(){
return $this->hasMany(\App\Post::class,'user_id','id');
}
<!-- 关注我的 -->
public function fans(){
return $this->hasMany(\App\Fan::class,'star_id','id');
}
<!-- 我关注的 -->
public function stars(){
return $this->hasMany(\App\Fan::class,'fan_id','id');
}
<!-- 我要关注某人 -->
public function dofan(){
$fan = new \App\Fan();
$fan->star_id = $uid;
return $this->stars()->save($fan);
}
<!-- 取消关注 -->
public function undofan(){
$fan = new \App\Fan();
$fan->star_id = $uid;
return $this->stars()->delete($fan);
}
<!-- 当前用户是否被uid关注 -->
public function hasFan($uid){
$this->fan()->where('fan_id',$uid)->count();
}
<!-- 当前用户是否关注了uid -->
public function hasStar($uid){
$this->stars()->where('star_id',$uid)->count();
}
个人中心demo
public function show(User $user){
<!-- 返回个数 srars_count fans_count posts_count -->
$user = User::withCount(['stars','fans','posts'])->find($user->id);
<!-- 文章取前10条 -->
$posts = $user->posts()->orderBy('create_at','desc')->take(10)->get();
}
关注用户
public function fan(User $user){
$m = \Auth::user();
$m->doFan($user->id)
}
ajax中是用post请求
$.ajaxSetup({
headers:{
'X-CSRF-TOKEN':$('meta[name="csrf-token"]').attr('content')
}
})
