Question

我正在尝试通过python中的selenium浏览facebook。到目前为止，这是我的剧本。

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

usr = ""# I have put 3 different accounts and tested it. Same error
pwd = ""

driver = webdriver.Chrome('E:\python_libs\chromedriver.exe')

driver.get("https://www.facebook.com")

assert "Facebook" in driver.title

elem = driver.find_element_by_id("email")
elem.send_keys(usr)
elem = driver.find_element_by_id("pass")
elem.send_keys(pwd)
elem.send_keys(Keys.RETURN)



elem = driver.find_element_by_css_selector(".input.textInput")
elem.send_keys("Posted using Python's Selenium WebDriver bindings!")



elem = driver.find_element_by_css_selector(".selected")

elem.click()
time.sleep(5)




driver.close()

在获得并正确安装了chromedriver的Windows上运行此脚本会返回错误。

Traceback (most recent call last):
File "C:\Users\Home\Desktop\facebook_post.py", line 28, in <module>
elem.click()
File "C:\Python27\lib\site-packages\selenium-2.42.0-           py2.7.egg\selenium\webdriver\remote\webelement.py", line 60, in click

WebDriverException: Message: u'unknown error: Element is not clickable at point (481,     185). Other element would receive the click: <input type="file" class="_n _5f0v" title="Choose a file to upload" accept="image/*" name="file" id="js_0">\n  (Session info: chrome=35.0.1916.114)\n  (Driver info: chromedriver=2.10.267521,platform=Windows NT 6.1     x86)'

我无法做到这一点。任何帮助将不胜感激。

Graph API在这里不可行，因为我想以自己的身份浏览而不是某些应用程序。但是，如果我自己可以通过图形API或其他方式进行浏览，请告诉我们。

如果您多次执行此过程，Selenium在WebDriverWait中有一些选项可以不浪费太多时间并检查元素是否可见。

Here是有关Selenium和Waits的文档 this是Selenium的Python文档的一部分，它讨论了Expected Conditions类。似乎“可点击”是您可以检查的一个条件。

在我的情况下，我编写了一个简单的函数来处理可见性和点击，并在每次需要点击动态的东西时调用它。

我的示例代码：

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

Browser = webdriver.Chrome()

def wait_until_visible_then_click(element):
    element = WebDriverWait(Browser,5,poll_frequency=.2).until(
        EC.visibility_of(element))
    element.click()
