<?php /** * 抓取快照生成工具 */ namespace App\Modules\XXXX\Commands; use Illuminate\Console\Command; use Illuminate\Support\Facades\DB; class RunSnapshotCommand extends Command { /** * The name and signature of the console command. *调用list显示命令的时候会被用到 * @var string */ protected $signature = 'huiliu:snapshot {--table_name=} {--start=}{--end=}'; /** * The console command description. *调用list显示命令的时候会被用到 * @var string */ protected $description = "抓百度快照!"; /** * @param string $table_name 表名 * @param int $start 开始id 默认：0 * @param int $end 结束id 默认：最大id */ public function handle() { $table_name = $this->option('table_name'); $start = empty($this->option('start') ) ? 0 : $this->option('start') ; $max = DB::table($table_name)->count(); $end = empty($this->option('end') ) ? $max : $this->option('end') ; DB::beginTransaction(); try { DB::table($table_name)->select('snapshot', 'url', 'id')->whereBetween('id', [$start,$end])->chunk(100, function ($users) { $table_name = $this->option('table_name'); foreach ($users as $user) { $kuaizhao = $this->kuaizhao($user->url); $update = DB::table($table_name) ->where('id', $user->id) ->update(['snapshot' => $kuaizhao]); var_dump($user->id); } }); DB::commit(); }catch (\Exception $e){ var_dump('error in update ,rollback~ '); DB::rollBack(); } } /** * 将回流url转换成快照 */ public function kuaizhao($url) { $text = $url; $url = 'http://www.baidu.com/s?word='.$text; $curl = app('curl'); $html = $curl->get($url); $regex = "/<a.?data-click=\"{'rsv_snapshot':'1'}.*?\">(.*?)<\/a>/is"; preg_match($regex,$html,$matches); $regex1 = "/(href=\").*?(\")/i"; if (!isset($matches[0])){ return $text; }else{ preg_match($regex1,$matches[0],$matches1); $replaceList = array("href=\"","\""); $url = str_replace($replaceList, "", $matches1[0]); return $url; } } }

使用方法：php artisan huiliu:snapshot --table\_name=XXXXX --start=12

功能：将会执行上面的handel方法，修改表名为XXXX的表中从id为12行开始到结束的url为对应的百度快照。

注：XXX根据需求修改
