Tips：只是提供一个思路，实际项目中还需维护代理池可用性等细节部分
实战步骤
- 框架及核心库部署
- 定时更新代理池进程
- 定时爬取列表页进程
- 主进程定时从Redis中读取列表页任务，有则将每一项丢给异步任务执行
环境
- CentOS 7.2
- PHP7.2
- Swoole 4.3.5
- Google Chrome 78.0.3904.108
- ChromeDriver 78.0.3904.105
Composer
- facebook/webdriver=1.7
- easyswoole/easyswoole=3.1.18
- easyswoole/curl=1.0.1
框架及核心库部署
1、安装EasySwoole 3.1.18版本
[root@ar414.com phpseleniumdemo] composer require easyswoole/easyswoole=3.1.18
[root@ar414.com phpseleniumdemo] php vendor/easyswoole/easyswoole/bin/easyswoole install

install success,enjoy!2.安装核心库facebook/webdriver、easyswoole/curl
[root@ar414.com phpseleniumdemo]# composer require facebook/webdriver=1.7
[root@ar414.com phpseleniumdemo]# composer require easyswoole/curl=1.0.1 3、确认运行没报错
[root@ar414.com phpseleniumdemo]# php easyswoole start

main server SWOOLE_WEB
listen address 0.0.0.0
listen port 9501
sub server1 CONSOLE => SWOOLE_TCP@127.0.0.1:9500
....定时更新代理池进程
Tips：代理资源请自行解决，这里只提供例子，实际是用不了的
1、 创建项目主目录
[root@ar414.com phpseleniumdemo]# mkdir App
#composer 指定App作用域
[root@ar414.com phpseleniumdemo]# cat composer.json
{
"autoload": {
"psr-4": { "App\\": "App/"
}
},
"require": {
"easyswoole/easyswoole": "3.1.18",
"facebook/webdriver": "^1.7",
"easyswoole/curl": "1.0.1"
}
}
#更新composer autoload
[root@ar414.com phpseleniumdemo]# composer dump-autoload2、创建进程目录（将代理池更新作为一个子进程随项目启动运行）
[root@ar414.com phpseleniumdemo]# mkdir App/Process 3、代理池定时爬取（使用Redis List类型保证最新代理IP在头部，爬虫逻辑每次从头部获取，一个代理IP只用一次）

*/
namespace App\Process;
use App\Lib\Curl;
use App\Lib\Kv;
use EasySwoole\Component\Process\AbstractProcess;
class UpdateProxyPool extends AbstractProcess
{
//这里的代理IP都只支持socks5协议
private $proxyListApi = "http://www.zdopen.com/ShortS5Proxy/GetIP/?api=%s&akey=%s&order=2&type=3";
const PROXY_KV_KEY = 'spider:proxy:list';
const TIMER = 15;
protected function initProxyListApi()
{
// $this->proxyListApi = sprintf($this->proxyListApi,$_ENV['PROXY_LIST_API'],$_ENV['PROXY_LIST_KEY']);
$this->proxyListApi = sprintf($this->proxyListApi,20191231231237085,'72axxxae0fe34');
}
public function run($arg)
{
$this->initProxyListApi();
//依赖 composer require easyswoole/curl=1.0.1
while (true)
{
$ret = Curl::get($this->proxyListApi);
var_dump($ret);
if($ret) {
$ret = json_decode($ret,true);
if($ret['code'] == 10001 && isset($ret['data']['proxy_list']) && !empty($ret['data']['proxy_list']) ) {
foreach($ret['data']['proxy_list'] as $proxy) {
$proxyItem = $proxy['ip'] . ':'.$proxy['port'];
Kv::redis()->lPush(self::PROXY_KV_KEY,$proxyItem);
}
}
}
sleep(self::TIMER);
}
}
}4、配置代理池更新进程随项目启动时启动（完整代码链接）
public static function mainServerCreate(EventRegister $register)
{
//更新代理池进程
ServerManager::getInstance()->getSwooleServer()->addProcess((new \App\Process\UpdateProxyPool('UpdateProxyPool', []))->getProcess());
}定时爬取列表页进程
爬取列表页进程（完整代码链接）
<?php
/**

* User: ar414.com@gmail.com
* Date: 2019/12/7
* Time: 22:01
*/
namespace App\Process;
use App\Lib\ChromeDriver;
use App\Lib\Kv;
use EasySwoole\Component\Process\AbstractProcess;
use EasySwoole\EasySwoole\Logger;
class ListSpider extends AbstractProcess
{
const API = 'https://www.188-sb.com/SportsBook.API/web?lid=1&zid=3&pd=%23AC%23B151%23C1%23D50%23E10%23F163%23&cid=42&ctid=42';
const LIST_KV_KEY = 'spider:list';
const TIMER = 20; //20秒执行一次
public function run($arg)
{
while (true)
{
try
{
$driver = (new ChromeDriver(true))->getDriver();
$driver->get(self::API);
$listStr = $driver->getPageSource();
var_dump($listStr);
file_put_contents("/www/wwwroot/blog/phpseleniumdemo/listStr.html",$listStr);
preg_match_all("/PD=(.*);/U",$listStr,$list);
$list = array_unique($list[1]);
if($list)
{
Kv::redis()->set(self::LIST_KV_KEY,json_encode($list));
}
var_dump('done');
$driver->close();
$driver->quit();
}
catch (\Throwable $throwable)
{
$driver->close();
$driver->quit();
Logger::getInstance()->log($throwable->getMessage(),'ListSpiderError');
var_dump($throwable->getMessage());
}
sleep(self::TIMER);
}
}
}主进程定时从Redis中读取列表页任务，有则将每一项丢给异步任务执行
1、完整代码链接
public static function mainServerCreate(EventRegister $register)
{
//更新代理池进程
ServerManager::getInstance()->getSwooleServer()->addProcess((new \App\Process\UpdateProxyPool('UpdateProxyPool', []))->getProcess());
//列表爬取进程
ServerManager::getInstance()->getSwooleServer()->addProcess((new \App\Process\ListSpider('ListSpider', []))->getProcess());
$register->set($register::onWorkerStart,function(\swoole_server $server,$workerId){
if($workerId == 0)
{
Timer::getInstance()->loop(30000, function () {
$ret = Kv::redis()->get(ListSpider::LIST_KV_KEY);
if($ret){
$ret = json_decode($ret,true);
foreach($ret as $item) {
TaskManager::async(function () use($item){
(new ItemSpider(true))->run($item);
return true;
}, function () use($item){
var_dump("{$item} Done");
});
}
}
});
}
});
