使用Selenium单击自动化

Question

为了从网站自动下载，我使用这个python脚本来自动执行点击操作。但点击不起作用。

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
import time

browser = webdriver.Firefox()
browser.maximize_window()
browser.implicitly_wait(20)
browser.get('http://download.cnet.com/most-popular/windows/')
linkElem = WebDriverWait(browser, 20).until(EC.element_to_be_clickable((By.PARTIAL_LINK_TEXT, "CCleaner")))
linkElem.click() # follows the "CCleaner" link

我第一次遇到这个错误：

selenium.common.exceptions.ElementNotInteractableException: Message: Element could not be scrolled into view

然后我添加这一行：

linkElem = WebDriverWait(browser, 20).until(EC.element_to_be_clickable((By.PARTIAL_LINK_TEXT, "CCleaner")))

现在我收到这个错误：

    linkElem = WebDriverWait(browser, 20).until(EC.element_to_be_clickable((By.PARTIAL_LINK_TEXT, "CCleaner")))
  File "/usr/lib/python2.7/site-packages/selenium/webdriver/support/wait.py", line 80, in until
    raise TimeoutException(message, screen, stacktrace)
selenium.common.exceptions.TimeoutException: Message: 

我尝试过人们用来解决这个问题但没有用的东西。

您的代码似乎与Chrome一起使用，我只添加了底部的两行，并下载了CCleaner。

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
import time

browser = webdriver.Chrome()  # Firefox()
browser.maximize_window()
browser.implicitly_wait(20)
browser.get('http://download.cnet.com/most-popular/windows/')
linkElem = WebDriverWait(browser, 20).until(EC.element_to_be_clickable((By.PARTIAL_LINK_TEXT, "CCleaner")))
linkElem.click() # follows the "CCleaner" link

download = browser.find_element_by_id('download-now-btn-text')
download.click()
