Selenium 只能在非无头模式下工作吗？

Question

我想在此页面上使用 Selenium： https : //www.avis.com/en/home

如果没有无头模式，该代码一切正常：

import requests
from bs4 import BeautifulSoup
import os, sys, time
import xlwings as xw
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.common.action_chains import ActionChains
from random import choice
from selenium import webdriver     
from sys import platform 

WAIT = 1
link = f"https://www.avis.com/en/home"
cd = '/chromedriver.exe'
options = Options()
# options.add_argument('--headless')
options.add_experimental_option ('excludeSwitches', ['enable-logging'])            
options.add_argument("user-agent=Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.106 Safari/537.36")    
driver = webdriver.Chrome (path + cd, options=options)
driver.get (link)
print(f"Read location VIE...")
driver.find_element_by_id("PicLoc_value").send_keys("VIE") 
driver.find_element_by_id("PicLoc_value").click()
time.sleep(WAIT)
print(f"Read from date 2021-07-06...")
driver.find_element_by_id("from").clear()
driver.find_element_by_id("from").click()
driver.find_element_by_id("from").send_keys("07/06/2021") 
time.sleep(WAIT)
print(f"Read to date 2021-07-21...")
driver.find_element_by_id("to").clear()
driver.find_element_by_id("to").click()
driver.find_element_by_id("to").send_keys("07/21/2021") 
time.sleep(WAIT)
driver.find_element_by_id("res-home-select-car").click()

但是当我取消注释行options.add_argument('--headless')它不再工作

我总是收到此错误消息：

Read location VIE...

Read to date 2021-07-21...

为什么这里 selenium 只能在没有无头模式的情况下工作？

Answer 1

使用无头模式时，您应该设置屏幕尺寸，因为无头模式下的默认屏幕尺寸是 800x600。
这就是为什么在无头模式下，对于在常规模式下运行良好的代码，您会遇到ElementClickInterceptedException错误。
所以，尝试添加

options.add_argument("--window-size=1920x1080")

此外，我们通常会添加以下内容：

options.add_argument('--no-sandbox')
options.add_argument('--disable-gpu')
