centos7上PhantomJS 過時以後改用Chrome時填的坑

忽然有個自動化需求因此準備使用模擬點擊的方法，

在使用以前的PhantomJS時，報錯

UserWarning: Selenium support for PhantomJS has been deprecated, please use headless versions of Chrome ……

這時候的方法就是換到chrome了，若是你沒裝過，那麼能夠按照這裏的方法去安裝，若是已經安裝了，也建議按照這裏的方法去排查可能出現的問題，

For Linux

1. Check you have installed latest version of chrome brwoser-> chromium-browser -version
2. If not, install latest version of chrome sudo apt-get install chromium-browser
3. get appropriate version of chrome driver from here
4. Unzip the chromedriver.zip
5. Move the file to /usr/bin directory sudo mv chromedriver /usr/bin
6. Goto /usr/bin directory cd /usr/bin
7. Now, you would need to run something like sudo chmod a+x chromedriver to mark it executable.

8. finally you can execute the code.

   from selenium import webdriver driver = webdriver.Chrome() driver.get("http://www.google.com") print driver.page_source.encode('utf-8') driver.quit() display.stop()

這樣只會就應該能夠用了，

若是還報錯，selenium.common.exceptions.WebDriverException: Message: '' executable may have wrong permissions.

那極有多是你沒把執行路徑添加到path，或者添加的路徑不完整，全路徑應該是包含chromedriver這個文件名的，不能只寫到它所在的文件夾，

eg,

chrome_path = '/usr/bin/chromedriver'
這樣就能夠了，下面是測試代碼，正常執行的，

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


chrome_options = Options()
chrome_options.add_argument('--headless')
chrome_options.add_argument('--disable-gpu')
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--disable-extensions')

chrome_path = '/usr/bin/chromedriver'
driver = webdriver.Chrome(executable_path=chrome_path, chrome_options=chrome_options)

driver.get("https://cnblogs.com/")
