Colaboratory上でSeleniumが使えないか試した(そしてダメだった)

Posted at

やりたかったこと

前回の続きとして、Beautiful SoupでHackMDへログイン状態でアクセスするためにSeleniumが使えないか試してみた。

やったこと

Firefoxのheadlessモードを試す

必要な物をインストール

!apt-get update
!apt-get install firefox
!wget https://github.com/mozilla/geckodriver/releases/download/v0.20.1/geckodriver-v0.20.1-linux64.tar.gz
!tar -zxvf geckodriver-v0.20.1-linux64.tar.gz
!cp ./geckodriver /usr/local/bin
!pip install selenium

コード

from selenium import webdriver
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary
from selenium.webdriver import FirefoxOptions

opts = FirefoxOptions()
opts.add_argument("--headless")
browser = webdriver.Firefox(firefox_options=opts)

browser.get('http://www.google.com')
print(driver.page_source)
browser.quit()

結果

WebDriverException: Message: Process unexpectedly closed with status signal
!cat geckodriver.log

Chromeのheadlessモードを試す

必要な物をインストール

!dpkg -i google-chrome-stable_current_amd64.deb

!wget https://chromedriver.storage.googleapis.com/2.38/chromedriver_linux64.zip
!unzip chromedriver_linux64.zip
!cp chromedriver /usr/local/bin/

コード

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

options = Options()
options.add_argument('--headless')
executable_path="/usr/local/bin/chromedriver"
service_args=["--verbose", "--log-path=/content/chromedriver.log"]

driver = webdriver.Chrome(chrome_options=options, executable_path=executable_path, service_args=service_args)

# Googleのトップ画面を開く。
driver.get('https://www.google.co.jp/')

print(driver.page_source)
