--headless 不是 selenium python chrome webdriver 中的一个选项

Question

I would like to have selenium run a headless instance of google chrome to mine data from certain websites without the UI overhead. I downloaded the chromedriver executable from here and copied it to my current scripting directory. The driver appears to work fine with selenium and is able to browse automatically, however I cannot seem to find the headless option. Most online examples of using selenium with headless chrome go something along the lines of:

import os  
from selenium import webdriver  
from selenium.webdriver.common.keys import Keys  
from selenium.webdriver.chrome.options import Options  

chrome_options = Options()  
chrome_options.add_argument("--headless")  
chrome_options.binary_location = '/Applications/Google Chrome   Canary.app/Contents/MacOS/Google Chrome Canary'`    

driver = webdriver.Chrome(executable_path=os.path.abspath(“chromedriver"),   chrome_options=chrome_options)  
driver.get("http://www.duo.com")` 

However when I inspect the possible arguments for the selenium webdriver using the command chromedriver -h this is what I get:

D:\Jobs\scripts>chromedriver -h
Usage: chromedriver [OPTIONS]

Options
  --port=PORT                     port to listen on
  --adb-port=PORT                 adb server port
  --log-path=FILE                 write server log to file instead of stderr, increases log level to INFO
  --log-level=LEVEL               set log level: ALL, DEBUG, INFO, WARNING, SEVERE, OFF
  --verbose                       log verbosely (equivalent to --log-level=ALL)
  --silent                        log nothing (equivalent to --log-level=OFF)
  --append-log                    append log file instead of rewriting
  --replayable                    (experimental) log verbosely and don't truncate long strings so that the log can be replayed.
  --version                       print the version number and exit
  --url-base                      base URL path prefix for commands, e.g. wd/url
  --whitelisted-ips               comma-separated whitelist of remote IP addresses which are allowed to connect to ChromeDriver

No --headless option is available.

Could anyone provide some clarification for this? Does the chromedriver obtained from the link above allow for headless browsing?

Thanks

Answer 1

--headless is not argument for chromedriver but for Chrome . --headless Run chrome in headless mode, ie, without a UI or display server dependencies. ChromeDriver is a separate executable that WebDriver uses to control Chrome and Webdriver is aa collection of language specific bindings to drive a browser.

I am able to run in headless mode with this set of options. I hope this will help:

from bs4 import BeautifulSoup, NavigableString
from selenium.webdriver.chrome.options import Options
from selenium import webdriver
import requests
import re  
options = Options()
options.add_argument('--headless')
options.add_argument('--no-sandbox')
options.add_argument('--disable-gpu')
browser = webdriver.Chrome(chrome_options=options)  # see edit for recent code change.
browser.implicitly_wait(20)

Update 12 Aug 2019:

old : browser = webdriver.Chrome(chrome_options=options)

new : browser = webdriver.Chrome(options=options)

Answer 2

Try

options.headless=True

The following is how I set up my headless chrome

options = webdriver.ChromeOptions()
options.headless=True
options.add_argument('window-size=1920x1080')
prefs = {
"download.default_directory": r"C:\FilePath\Download",
"download.prompt_for_download": False,
"download.directory_upgrade": True}
options.add_experimental_option('prefs', prefs)
chromedriver = (r"C:\Filepath\chromedriver.exe")

--headless不是chromedriver而是Chrome参数，你可以在这里看到更多的参数或 chrome 的命令行开关
