The content of this article is about thinkphp5 using the workerman timer to regularly crawl news information of a certain site. The content is very detailed. Friends in need can refer to it. I hope it can help you.

1. First install workererman through composer. There are detailed instructions in the extension of thinkphp5 complete development manual-"coposer package-"workerman:

#在项目根目录执行以下指令
composer require topthink/think-worker

Copy after login

2. Create the service startup file server.php in the project root directory:

<?php

define(&#39;APP_PATH&#39;, __DIR__ . &#39;/application/&#39;);
define("BIND_MODULE", "server/Worker");
// 加载框架引导文件
require __DIR__ . &#39;/thinkphp/start.php&#39;;

Copy after login

3. Create the server module in the application and create the controller Worker.php in the server:

<?php
namespace app\server\controller;
use think\worker\Server;

class Worker extends Server
{

    public function onWorkerStart($work)
    {
        $handle=new Collection();
        $handle->add_timer();
    }


}

Copy after login

4. Create the Collection.php class

<?php
namespace app\server\controller;
use app\common\model\ArticleModel;
use think\Controller;
use Workerman\Lib\Timer;

class Collection extends Controller{

	public function __construct(){
		  parent::__construct();
	}

	public function add_timer(){
        Timer::add(10, array($this, &#39;index&#39;), array(), true);//时间间隔过小，运行会崩溃
    }
    /**
     * 采集数据
     */

    public function index(){

       
        $total=$this->get_jinse();
        return json([&#39;msg&#39;=>"此次采集数据共 $total 条。",&#39;total&#39;=>$total]);
    }

  
    /**
     * 获取金色财经资讯
     */
    public function get_jinse(){
        $url="https://api.jinse.com/v4/live/list?limit=20";
        $data=$this->get_curl($url);
        $data=json_decode($data);
        $data=$data->list[0]->lives;

        $validate=validate(&#39;Article&#39;);
        $items=[];

        foreach ($data as $k=>$v){

            preg_match(&#39;/【(.+?)】(.+)/u&#39;,$v->content,$content);

            if(!@$content[2]){
                continue;
            }


            $list=array(
                &#39;source_id&#39;=>$v->id,
                &#39;source&#39;=>&#39;金色财经&#39;,
                &#39;title&#39;=>trim(preg_replace(&#39;/.*\|/&#39;,&#39;&#39;,$content[1])),
                &#39;content&#39;=>$content[2],
            );
            if($validate->check($list)){
                $items[]=$list;
            }
        }
        if($items){
            krsort($items);
            $model=new ArticleModel();
            $model->saveAll($items);
        }
        return count($items);
    }
    public function get_curl($url){
        $ch=curl_init();
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch,CURLOPT_URL,$url);
        curl_setopt($ch,CURLOPT_HEADER,0);
        curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
        $output = curl_exec($ch);

        if($output === FALSE ){
            echo "CURL Error:".curl_error($ch);
        }
        curl_close($ch);
        // 4. 释放curl句柄

        return $output;

    }
  
}

Copy after login
