python - selenium.common.exceptions.ElementNotVisibleException : Message: element not visible while invoking send_keys in ubuntu headless browser through python

Question

我在使用 send_keys 时遇到问题

options = webdriver.ChromeOptions()
options.add_argument('headless')
driver = webdriver.Chrome(executable_path= '/home/ec2-user/chromedriver', chrome_options=options)
base_url = "https://www.xxxxxxxx.com/"
driver.get(base_url)
driver.find_elements_by_xpath("//input[@id = 'homepage_search_box']")[0].send_keys("Pink's Hot Dogs")

上面的代码在 Windows 中完美运行，但是当涉及到 ubuntu 时，它会抛出类似的错误

selenium.common.exceptions.ElementNotVisibleException: Message: element not visible
  (Session info: headless chrome=67.0.3396.99)
  (Driver info: chromedriver=2.40.565383 (76257d1ab79276b2d53ee976b2c3e3b9f335cde7),platform=Linux 4.14.47-56.37.amzn1.x86_64 x86_64)

HTML:

<form class="form-inline" onsubmit="simple_search(jQuery('#homepage_search_box').val());return false;">
    <div class="form-group col-md-8">
        <label class="sr-only" for="homepage_search_box">Company Name or Report #</label>
        <input name="homepage_search_box" id="homepage_search_box" class="form-control" placeholder="Company Name or Report #" type="text">
    </div>
    <div class="form-group col-md-4">
        <button type="submit" class="btn btn-default">Search</button>
    </div>
</form>

谁能帮忙

driver.find_elements_by_xpath("//input[@id = 'homepage_search_box']")[0]

要将字符序列发送到搜索框，您需要引发WebDriverwait以使所需的元素可点击，并且您可以使用以下任一方法解决办法如下:

• 代码块:

  # -*- coding: UTF-8 -*-
  from selenium import webdriver
  from selenium.webdriver.common.by import By
  from selenium.webdriver.support.ui import WebDriverWait
  from selenium.webdriver.support import expected_conditions as EC
  
  options = webdriver.ChromeOptions() 
  options.add_argument("start-maximized")
  options.add_argument('disable-infobars')
  options.add_argument('--headless')
  driver=webdriver.Chrome(chrome_options=options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
  driver.get("https://www.ripoffreport.com/")
  WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input.header-field#header-search-text"))).send_keys("Pink's Hot Dogs")
  # WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//input[@class='header-field'][@id='header-search-text']"))).send_keys("Pink's Hot Dogs")
  print("Search Text Sent")
  

• 控制台输出:

  Search Text Sent
