如何使用python硒在chrome浏览器上单击下载图标

Question

我想通过单击Chrome浏览器上的下载图标来下载文件。 我尝试了几种方法，如Xpath和CSS，但它不起作用。请使用Python 3.x和Selenium对此有任何解决方案，请告诉我。

下面是我尝试过的代码，

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.chrome.options import Options
import time
class TEAutomation:
def automateTask(self):
chromeOptions = Options()
chromeOptions.add_experimental_option("prefs",{"download.default_directory": "/home/vishal/Documents/PythonProgram/"})
baseUrl = "https://www.te.com/commerce/DocumentDelivery/DDEController?Action=showdoc&DocId=Customer+Drawing%7F160743%7FM2%7Fpdf%7FEnglish%7FENG_CD_160743_M2.pdf%7F160743-1"
driver = webdriver.Chrome(executable_path="/home/vishal/PycharmProjects/VSProgramming/drivers/chromedriver",chrome_options=chromeOptions)
driver.maximize_window()
driver.get(baseUrl)
driver.implicitly_wait(10)
driver.find_element(By.XPATH,'//*[@id="download"]').click()
#driver.find_element(By.CSS_SELECTOR, '#download').click()
time.sleep(5)
driver.quit()
molexAuto = TEAutomation()
molexAuto.automateTask()

提前谢谢你。

也许当您尝试单击元素时，该元素仍未加载，请尝试使用WebDriverWait等待它，我没有 chrome，所以您必须自己测试：

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.support.wait import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
import time
class TEAutomation:
def automateTask(self):
chromeOptions = Options()
prefs = {
"download.default_directory": "/home/vishal/Documents/PythonProgram/",
"plugins.always_open_pdf_externally": True
}
chromeOptions.add_experimental_option("prefs", prefs)
baseUrl = "https://www.te.com/commerce/DocumentDelivery/DDEController?Action=showdoc&DocId=Customer+Drawing%7F160743%7FM2%7Fpdf%7FEnglish%7FENG_CD_160743_M2.pdf%7F160743-1"
driver = webdriver.Chrome(executable_path="/home/vishal/PycharmProjects/VSProgramming/drivers/chromedriver",chrome_options=chromeOptions)
driver.implicitly_wait(10)
driver.maximize_window()
driver.get(baseUrl)
time.sleep(5)
driver.quit()
molexAuto = TEAutomation()
molexAuto.automateTask()
