如何配置和使用远程Selenium节点

By minirplus on 2020-02-17 in DEV

为了避免本地Selenium服务器的稳定性问题，以及解决内网的可用性问题，采用Docker将Selenium服务安装在在线节点上，方便程序随时调用。

环境

Debian 10

1.安装Docker

apt-get remove docker docker-engine docker.io containerd runc

curl -fsSL https://download.docker.com/linux/debian/gpg | sudo apt-key add -

apt-get update

apt-get install docker-ce docker-ce-cli containerd.io

2.运行image

1	docker run -d -p 4444:4444 -v /dev/shm:/dev/shm selenium/standalone-chrome:3.141.59-zirconium

3.安装Facebook\WebDriver

1	composer require php-webdriver/webdriver

3.连接远程Selenium节点

<?php

// include composer autoload

require_once 'vendor/autoload.php';

use Facebook\WebDriver\Remote\DesiredCapabilities;

use Facebook\WebDriver\Remote\RemoteWebDriver;

use Facebook\WebDriver\WebDriverBy;

use Facebook\WebDriver\Exception\NoSuchElementException;

use Facebook\WebDriver\Exception\WebDriverCurlException;

use Facebook\WebDriver\Exception\HttpCommandExecutor;

use Facebook\WebDriver\chrome\ChromeOptions;

$host = 'http://localhost:4444/wd/hub';

$options = new ChromeOptions();

$options->addArguments([

'--aggressive-cache-discard',

'--disable-gpu-program-cache',

'--disable-gpu-shader-disk-cache',

'--gpu-program-cache-size-kb=1',

'--mem-pressure-system-reserved-kb=1',

'--disk-cache-dir=null'

]);

$caps = DesiredCapabilities::chrome();

$caps->setCapability(ChromeOptions::CAPABILITY, $options);

$driver = RemoteWebDriver::create($host, $caps);

try {

$result = 0;

// visit target

$driver->get('https://www.amazon.co.jp/gp/offer-listing/B0141ZPO1E/ref=dp_olp_new?ie=UTF8&condition=new');

// search price

$element = $driver->findElement(WebDriverBy::xpath('//*[@id="olpOfferList"]/div/div/div[2]/div[1]/span[1]'));

$result = $element->getText();

echo $result.'<br/>';

} catch ( \Exception $e) {

echo 'Exception: '.json_encode( $e->getResults() ).'<br/>';

}

ob_flush();

flush();

sleep(10);

}
